Applying coatings at low temperatures. Is it possible to paint in sub-zero temperatures At what temperature to varnish wood
What to do if you need to paint the fence, and the outside temperature is negative? A decade ago, the answer would have been obvious: wait for warm weather. Modern technologies offer coloring compositions for use in the cold.
To paint or not to paint
To begin with, we will determine whether it is possible to paint the fence in winter, in terms of the suitability of materials.
The metal does not change its structure when climate and temperature change. The fact is that it does not absorb water, and this is its main advantage. Over time, a fence made of a profiled sheet can only heat up and stretch a little in a linear direction, and when it cools down, return to its shape. Compositions for painting metal are adapted to this quality - they form an elastic film on the surface.
Painting wooden fence not recommended in winter. The fact is that moisture constantly accumulates between the fibers of the tree. At positive temperatures, there is a constant moisture exchange in the wood, in frost the water freezes, expanding the structure of the material, the applied layer of enamel will seal the ice, and when thawed, the water will repel the paint and the latter will bubble. In addition, the process of active decay will begin.
Painting the wood is possible, but after the test: several strips of wide adhesive tape are glued to a clean area of \u200b\u200bthe fence. After a day or two, the result is evaluated: if condensation has formed on the surface of the film or there is frost on the inside, then painting will be meaningless. In the absence of water loss, the fence can be covered with a layer of enamel.
Features of work in the winter
Is it possible to paint the fence at sub-zero temperatures - found out. The next question is how to work at negative temperatures. There are several basic rules:
- Use only those intended for use in winter conditions enamel. Mainly alkyd paints based on solvents that do not change their consistency in frost. Sellers regulate them as paints for metal, but use on wooden surfaces is allowed.
- The surface to be painted must be dry.
- Metals must be degreased with acetone or isopropanol.
- It is not recommended to work in the temperature range of -5…+50С. At high humidity there is a high chance of condensation.
- The coloring composition must be necessarily warm (above 00C). If the design is large and requires a long time to cover, it is recommended to put the bucket of paint in a container with warm water to maintain a comfortable consistency of the working composition.
- You can often hear advice: warm up the metal with a hairdryer before painting. It is worth remembering that the material has a high heat transfer and instantly cools in the cold. Therefore, you need to paint with a hairdryer in your hands or leave this idea.
Ordinary enamels in the cold dry for a long time - from 3 to 7 days. This should be remembered before applying the second layer. Special compositions dry from 1 hour.
Overview of effective enamels for winter use
Exists a large number of specially designed coloring compositions for operation at low temperatures. They differ from the usual:
- Do not freeze in the cold;
- Form an elastic layer even under extreme conditions;
- Suitable for wood and metal;
- Combine anti-corrosion, fire, antifungal (for wood) properties;
- Dries quickly compared to conventional formulations.
The main selection criterion is the temperature range of application. And the price, of course, matters.
We will consider the main compositions suitable for painting simple structures.
SEVERON
CJSC Alp-Emal - large domestic manufacturer coatings, supplies the market with the most widely used composition SEVERON, it is used for painting large objects of national importance (oil pipelines, construction cranes, bridges, power lines, etc.).
The coating is fire-resistant, forms a slightly combustible film, resistant to high temperature+150°С. The lower threshold of stability is -60°С.
Painting metal fence Severon enamel does not require additional priming, and the application of two or three layers can be done in one day.
Price - about 130 rubles / liter.
Primer-enamel SEREROL
The product of the same Alp-Emal factory is compatible with different materials, has similar characteristics:
Enamel does not require a primer, but the surface must be free of dirt and grease. The application is carried out with the usual devices - rollers, brushes. Skin contact should not be prolonged.
Price - about 160 rubles / liter.
ORTAMET
This winter-hardy composition is suitable for covering a rusted fence. It is applied at temperatures up to -15 ° C with any tools. The active base transforms the centers of corrosion into a reliable protective covering dark brown or black. Suitable for use on all metals. For the application to be effective and to obtain the ideal effect, it is necessary to remove the old peeling paint from the fence. Drying time "to touch" - 2-3 hours, layer polymerization - about a day under adverse conditions.
Price - about 140 rubles / liter.
ZIMAPRIM
Special compound resistant to chemicals. This can be recommended in areas where roads are abundantly sprinkled with melting substances. If your fence is constantly in contact with treated snow, its outer side can be treated with winterprime. The paint is expensive - about 230 rubles / liter.
Primer-enamel quick-drying on rust "ANTIKOR" winter
Universal enamel for metal, wood, concrete and stone.
The coating is resistant to absolute humidity and a wide temperature range from -60 to + 300°C.
The preparation of the base is carried out in the usual way: removal of old paint, sanding, degreasing. Application is carried out with a roller, brush or spray gun. The average price of primer-enamel for rust "Anticor" is 190 rubles / liter.
Zinc-filled enamel primer "ZITAN"
This composition is suitable for a low-carbon steel fence. The paint forms a matte protective film that prevents the penetration of moisture and hides the defects of the metal surface.
Priming enamel FESTPRO XC-7200 ®
There are silicon-containing, chemical-resistant and weather-resistant preparations for winter application, but they are intended for coloring. industrial facilities constantly in contact with aggressive media. Such enamels are expensive and it is irrational to use them for a fence.
Conclusion
Painting the fence in winter is possible, the main thing is to properly prepare the surface and choose the composition. The list of colors is not limited to the above list. Read the instructions, choosing the right composition, this is the main source that will provide information on the application and method of applying the drug to the surface.
Went to a seminar organized by publishing house"Origami" magazine "Ochistka.Okraska", held in St. Petersburg on November 14-15, 2011 under the title "The practice of applying paint and varnish coatings at low temperatures."
In addition to listening to the information that I know about the types of corrosion and how to deal with it, about the Wiwa painting equipment, which I will talk about later in the Equipment section, where the experience of working with many painting machines is already described, and showed a small master class on coloring of corrugated board.
I also listened to a very interesting lecture by technologists of the Morozov Chemical Plant on applying paint at low temperatures.
Morozovsky Chemical Plant is the oldest Russian enterprise for the production of enamels. It was he who began to produce heat-resistant enamels of the well-known types KO and OS. I will also talk about enamels, but later, in the Materials section. I think it will be interesting.
I had a long-standing correspondence relationship with MHZ. 
It was very nice to meet you in real life. There is no doubt about their professional approach to ACS. What are the trips of the chief technologist of the Moscow Chemical Plant Urvantseva G. to many facilities where they are painted with enamels, her constant consultations and technical supervision over the production of painting at the facilities. Great amount grateful comments about MHZ.
So, back to the main topic of the seminar.
Paints can be applied at low temperatures. For this, the following conditions must be met:
1) It is impossible to paint at a temperature of +-5 degrees. C. This is due to the formation of condensate, dew, on the metal surface. In general, this temperature is the worst for staining with any paints.
2) The surface to be painted and the paint must be at the same temperature. When applied by airless spray warm paint on a cold surface, when two materials come into contact different temperatures condensation also forms. Even if we all understand that airless dyeing is very fast, nevertheless, condensation forms.
3) The question of how to paint concrete surfaces at low temperatures requires additional consideration.
Of course, a lot has been said about the fact that it is possible to paint with OS and KO enamels produced by MHZ, up to -10 degrees C, without loss of quality, but I did not have to work with them at such a temperature.
I had to work with enamels:
PF-115 and XV-0278, at temperatures from -0 to -10 degrees. S. It was just cold to work on. I painted in a cold room, with paint that was stored there.
ХВ -174 in the open air at a temperature of 0, + 5 degrees C metal structures of the same temperature, paint stored at the same temperature.
PF-100 indoors at a temperature of -5, + 7 degrees C, which was eventually raised to +12 degrees C
As seen, temperature regime not followed everywhere.
As a result:
Application:- just like always.
Drying: XB 0278, 2-3 hours (same as always)
PF-100 - drying 2-3 days (according to the passport - a day)
PF - 115 drying from 7-10 days or more (according to the passport - a day)
XB -174, the same as always, drying 2-3 hours.
Polymerization: XB 0278, 5-7 days (same as always).
PF-100, 5 days.
PF - 115, not known. When we left the object, it was not dry yet 🙂
XB -174, drying 2-3 hours (same as always).
Exploitation: XB 0278 has been standing for more than a year, without coating defects.
PF-100, no negative reviews, it is impossible to get into the painting area
PF - 115, stood for half a year, in the fall it began to fly off with mugs.
XB -174, stood for a year. Started to fly off burdocks.
It should be noted that PF-100 and XV-0278 enamels are classified as primer-enamels for rust. They have additional additives in their formula, have an order of magnitude different cost. Although I am skeptical about coatings such as primer-on-rust, nevertheless, in these conditions they showed the best results.
PF-115 based on Russian SNIP is not recommended for painting metal structures used in industrial environments. Therefore, the legality of the project for painting PF-115, metal structures is in great doubt. Even under the conditions of application at low temperatures, she behaved in the most pleasing way.
An example of painting XB-174, which does not differ from XB-0278 in its plastic properties, showed non-compliance with technologies and the result was not long in coming.
Thus, on a personal practical experience from my observations, I can confirm quality coating can be done at low temperatures. The main thing is not to carry out painting work at + - 5 degrees. FROM.
The need to paint a concrete floor, fence, facade or metal structures, is also present in winter, when it is cold outside and the temperature reaches -15C °. Not every paint or primer copes with this task. Many paint and varnish materials cannot be used in the cold, therefore, for outdoor work, in winter, special materials are needed that are suitable for use at low temperatures and provide high-quality coverage under these conditions.
NPP GC produces a number of special paints for the winter period in order to provide its customers with the opportunity to perform work at any time of the year:

Wood paints for outdoor use in winter

PRICE |
For coloring wooden facades buildings and other wooden surfaces. Is different high level hiding power, weather resistant, chemical resistant detergents and UV radiation, water-repellent. It is used at negative temperatures up to -5°С.
The recommended temperature threshold for painting work should not be less than +5 degrees C. If for objective reasons there is an urgent need to varnish the floor at a negative temperature, it is worth paying close attention to preliminary surface preparation.
In addition to the fact that any floor must be cleaned of traces of the old coating, cleaned, washed and dried, there are additional recommendations for the preparation of various materials varnished surface at temperatures below 0 C:
- it is advisable to paint or varnish concrete floors no earlier than a year after creation, so that the surface is “dust-free”. Without pre-exposure, it is possible to carry out painting work on bulk concrete floors in workshops, hangars, warehouses;
- the metal floor must first be removed from moisture or ice and treated with a torch of a burner (gasoline or gas);
- varnishing a wooden floor at low temperatures is extremely undesirable due to frozen moisture particles in the porous structure of wood - the surface is unevenly protected by paintwork materials. To make sure that the base does not contain excess moisture, you can use a piece of adhesive tape glued to the floor surface for a day. If no condensation appears on the tape during this time, varnishing and staining can be carried out.
What minus temperature can wood varnish withstand?
Modern manufacturers of coatings, due to additional inclusions, have ensured that their products can withstand short-term sub-zero temperatures. However, temperatures below -5°C are detrimental to wood varnished products.
Experienced builders advise covering the indoor floor with outdoor varnish, which can withstand lower temperature conditions, but there are “pitfalls” here as well. If a large traffic is planned in the room, i.e., a load on the surface, the varnish for outdoor work will undergo very rapid abrasion and will be covered with “paths”.
What else is worth thinking about when painting at low temperatures?
For a quality result, namely for an ideal lacquered surface, it is necessary to remember such nuances as:
- Quality tools. Ideal wood varnish brush- wide and flat. The bristle can be both natural and artificial. The basic rule is that artificial pile should not be painted, otherwise the surface will acquire a dirty shade with stains;
- Rationally selected varnish. In order for the result to meet expectations, carefully study all the offers of coatings manufacturers. Do not hesitate to ask for help from the specialists of building stores or online markets: one “missed” question threatens not to be the most impressive effect of the work done.
- Lacquer applied at low temperatures dries 3 times longer. Professionals in such cases recommend after applying coatings block the object with scaffolding with film and provide with a thermal gun.
Before deciding on such a desperate act as varnishing a floor at sub-zero temperatures, repeatedly weigh the pros and cons. The formation of condensate, which adversely affects adhesion, is unavoidable under such conditions. This means that such a coating will not differ in durability.
Are there facade paints that can be applied at low temperatures?
Facade paints, which can be applied at low temperatures, are called all-weather (or winter) paints.
All-weather acrylic frost-resistant paint Akrial-Lux designed specifically for severe climatic conditions, including areas with abrupt changes weather conditions. Winter paint is used for painting facades made of concrete, foam concrete, asbestos cement in all climatic zones, in industrial centers with high air pollution.
All season winter paint for facade works Akrial-Lux possesses high resistance to an ultraviolet and atmospheric influences, forms a strong vapor-permeable covering. It has excellent adhesion to concrete, foam concrete, asbestos cement, brick, plaster.
Is it possible to paint the facade of a wooden house in rainy or cold weather?
It fits well on surfaces previously painted with oil, alkyd, latex and other paints (with the exception of lime paints).
All season winter paint Akrial-Lux applied to the surface with a brush, roller or paint sprayer in 1-2 layers. Painting work should be carried out at an air temperature not lower than -20ºС, provided that the treated surface is dry and not icy. Winter paint significantly increases the moisture resistance, weather resistance and service life of the facade.
For the restoration and restoration of building facades, special restoration paint is used. facade. This special paint is recommended for especially responsible and construction and restoration works on the most complex objects.
The paint can be applied at any time of the year at temperatures from -20°С to +35°С.

Back to the list of questions
print version
The main part of painting work is carried out at positive temperatures, the lowest recommended threshold is +5 C. However, sometimes there is an urgent need to paint, for example, the facade of a building, in negative temperatures. This may be due to both updating the appearance of the building, and with the delivery of the facility on time.
How facade paint behaves at sub-zero temperatures
In addition, there are still objective production reasons for these works at temperatures below 0 C.
Rules and recommendations for painting surfaces at sub-zero temperatures
Compliance general principles technology of painting works, implies a thorough preparation of the surface for painting. Everything is thoroughly cleaned of traces of old paint, processed with sandpaper, putty is applied to all irregularities, and, if necessary, coated with a primer. So, before painting the wall or the surface to be painted must be clean and dry.
- metal coloring
If we are going to paint metal, then there should be no condensation or ice on it. Mechanical cleaning of the surface will not work, there will still be a thin layer invisible to the eye. Therefore, in addition to removing moisture microparticles, it is recommended to treat the surface with a torch of a gas or gasoline burner.
- wood coloring
It is strongly not recommended to paint a tree in the cold season.
This is due to the fact that between the fibers of wood there is always a certain percentage of moisture. At negative values water between the fibers turns into ice and the surface is incompletely impregnated with paintwork materials. If, nevertheless, an urgent need arose, stick a piece of adhesive tape 5 * 5 cm on wooden surface and, if condensation does not appear on the adhesive tape in a day, then such a surface is more or less suitable for painting. Thus, when painting wood, you must make sure that the substrate does not contain frozen water.
- concrete coloring
Concrete, like wood, has a porous structure. In addition, concrete structures outdoor conditions subject to weathering. Another feature of concrete is that it is desirable to paint it no earlier than 1 year after installation. This is due to its hygroscopicity and the need for dedusting. Basically, in negative temperatures, without preliminary exposure, a self-leveling concrete floor is painted in hangars, workshops and warehouses handed over to the customer.
- painting brick, plastered surface
Applies general technology surface preparation before painting.
With such a boundary condition, condensation forms on the surface to be painted, especially on a metal one. The value of painting for condensation, even if imperceptible, will impair adhesion and significantly reduce the polymer properties of the paint used. In the future, this will certainly affect the quality and durability of the entire coating.
When painting objects in conditions of negative temperatures, be sure to keep in mind that the drying time of paintwork materials can be 2-3 times longer than the similar painting time at positive outdoor temperatures. Therefore, after applying paintwork materials to the surface, it is desirable to cover the object with scaffolding with a film and provide an additional thermal gun.
The choice of paint must be approached very seriously. The final result of the work depends on your choice - the durability and quality of the resulting protective coating.
Paints that are used at low temperatures
Universal(wood, concrete, plaster, brick)
Tikkurila Euro Facade(up to -20 C)
Forms a high quality weather resistant coating. For the first layer, the paint is diluted with Euro Facade thinner in the amount of 10-20% of the total mass. For the final coating, the paint is applied without dilution. After drying, a durable matte finish is obtained. When used, the temperature of the applied paint must be at least +10 C. Consumption 1l./6m2.
Metal
Miranol - thixotropic (jelly-like) high gloss alkyd enamel, diluted up to 30% by volume. Good light and weather resistance. Consumption 1l/12-14m2.
Pansarimaali- excellent alkyd semi-gloss paint with active anti-corrosion properties. It is mainly used for painting roofs, drainpipes, railings and similar metal structures. In negative temperatures, it needs to be diluted up to 30% with a solvent. Consumption 1l/8-12m2.
Garden- semi-gloss alkyd enamel, with excellent wear-resistant characteristics. When working below 0 C, it needs to be diluted with solvents up to 30% by volume. Consumption 1l/8-12m2.

Benefits of paint over rust
AT repair work we are often faced with the need to paint metal pipes and metal structures, as well as other metal products. The big problem here is that the metal often oxidizes in the presence of moisture and rusts. To remove rust from metal, it requires mechanical cleaning, then anti-corrosion treatment and painting. This is a very troublesome undertaking, often structural details are not available for cleaning rust.
Finally, to facilitate this process, rust paints were created, they are also very beautiful as decorative coating. These are modern paints of a wide spectrum of action.
The advantages of this type of paint:
- applied directly to the rusty surface
- creates a coating on the metal that repels water and dirt
- covers the base well
- strong adhesion to the base
- anti-corrosion
- fast drying
- coating is durable, up to 8 years
- wealth of colors
The disadvantages of this type of paint:
- you can not paint with her objects that are heated to more than 150 degrees Celsius.
- it is impossible for objects painted with this paint to come into contact with drinking water
Types of rust paints
To achieve the desired effect when processing these paints, it is necessary to understand their types and areas of applicability. Rust paints are classified according to the basis of the main substance, purpose and maximum temperature usage, number of components. So, there are water-based paints with phosphoric acid, they are the cheapest, but they have low resistance to environment; there are two-component additives with epoxy resins, polyurethane, and corrosion inhibitors. According to the main substance, paints are divided into:
- Epoxy. Toxic, do not use at home. Suitable for highly heated metal structures.
- Oil. Contains drying oil and natural oils. Temperature resistant. Anti-corrosion protection outdoors is low, suitable indoors.
- Alkyd. For galvanized metal. Extremely flammable, should not be used on highly heated metal structures. Very adhesive.
- Acrylic. Prolonged anti-corrosion protection. Suitable for highly heated structures, such as heating elements, indoors and outdoors.
- Special paint for rust 3 in 1. Reduces the cost and shortens the restoration of rusted metal. Quickly applied directly to bare metal. Low cost. Includes resin, anti-corrosion elements. Highly adhesive, fast drying, protects for up to 8 years.
- Hammer colors. Gives a rough, hammer-like finish with a metallic sheen.
The paint uses alkyds, acrylics, epoxies, aluminum powder. Gives also glossy and semi-gloss shades. Also suitable for non-ferrous metals. The primer before drawing can be not applied. The first layer acts as a primer, the second is anti-corrosion, the third acts as the actual enamel. Do not paint objects heated above 150 degrees.
- Anti-corrosion paints for car body repair.
- Aerosol form. It has many functions, convenient for touching up in places of painting defects and difficult access. Also suitable for non-ferrous metals and other natural materials. The universal grade of this paint also performs the functions of a primer, anti-corrosion and decorative.
Methods for protecting metal from rust:
- Active electrochemical protection
- Galvanic sacrificial protection
- Cold galvanized matella
- Rust capping in a polymer film, metal painting
- Phosphating, rust conversion
Outdoor Rust Paint
Metal structures where anti-corrosion painting is necessary:
- plumbing and heating pipes
- metal fences
- architectural plan metal structures
- greenhouses
- lattices, gates
Applying rust paint to the surface
In order to achieve the expected effect during the repair, it is necessary to correctly follow the stages of processing the object with these paints. You need to carefully follow the sequence of actions, otherwise your work may be defective.
- Paint heating systems only when they are turned off, use heat-resistant paint that can withstand up to 150 degrees.
- Furnaces are painted with compositions that can withstand up to 500 degrees.
- Non-ferrous metals require special primers.
- Outdoor facilities require organic solvents.
- If the rust is loose, it must first be removed, otherwise the paint will peel off.
- Before using the paint, check that its heat resistance corresponds to the heating temperature of the product to be painted.
best paint for rust
The price depends on the company and on the components.
Let us pay attention only to the most widely used varieties of paints, the high quality of which has been proven in practice.
Hammerite for rust:
The most popular. With its help, you can achieve the effect of gloss, hammer and slightly matte. Does not allow dirt to accumulate on the structure. It is used in the design of cottages, in industrial construction, in roofing works, in painting communications, industrial and agricultural equipment, various metal structures. The surface may not be cleaned.
PromAlpForum
Withstands from -20 to + 80 degrees of temperature. The paint acts simultaneously as a primer, rust converter and decorative coating. Dries quickly, multiple coats applied per day. It is necessary to ensure that the surface does not exfoliate before painting. Do not use with bituminous materials. Non-ferrous metals must first be primed.
Primers-enamels for rust:
Very easy to use, really facilitate the process of destroying rust when applied. They give the effect of 3 in 1, i.e. act simultaneously as a primer, anti-corrosion agent and decorative coating. The surface is cleaned of dirt, degreased with white spirit, rust is removed with a spatula, metal brush or emery. Mix and apply two coats at intervals of 30 minutes to 5 hours. If this time has elapsed, the second layer can be painted only after 30 days.
Other popular most purchased rust paints:
- Enamel primer “Rzhavoyed-Universal. Cleans and primes the base. The filled color is created with the second layer.
- Paint "Stainless steel". Alkyd based, quick drying, anti-corrosion.
- Paint "Meerk iron". Good lays down, masks flaws. Doesn't do much against rust. Low price.
- Primer-enamel Alpina (Direct auf Rost). There is no lead, unlike many other paints. Does not smell, creates a durable coating, fits well. First, it is enough to remove dirt from the metal.
In general, when using rust paint, it is important to read its instructions carefully because there can be significant differences in application. different varieties these colors. At the same time, it should be noted that in some instructions the paint quality is somewhat overestimated, so it is necessary to check in other sources whether it is really necessary to prime the surface before use, as well as such indicators as, for example, paint suitability at -20 degrees frost, are written only for force majeure, in reality this does not mean that it is usually used at this temperature.
Usually, painting work is planned for the warm season, when the temperature regime is most favorable for this. The lower recommended temperature threshold for painting is plus 5 degrees. But now there are many modern paints and soils that are suitable even for negative temperatures. In this regard, the minimum possible limit at which temperature you can paint on the street has changed.
Features of painting work in winter
In industrial conditions, the need for painting at low temperatures arises if you need to hand over the object on time, or you urgently need to update the surface of the building. In everyday life, such urgency is rarely observed, but it still happens. There are a number of painting features in the cold season:
- The most unfavorable temperature the use of paints, enamels and primers in winter - from minus 5 degrees to plus 5 degrees. Even in cold weather, it is better to work, because it is in the specified range that condensation will form on any surface. In the presence of moisture, the adhesion of the coating deteriorates greatly, the properties of the paints change. The quality of the coating is reduced, it will not last long.
- If you decide to paint facades in cold weather, you need to remember that facade paint of any brand dries 2-3 times longer than in warm weather. To get a high-quality coating, you need to use a thermal gun for drying or stretch the film on scaffolding.
- You should choose only enamel suitable for the winter season, a primer. Using the wrong material will cause it to freeze, and the ice will not allow the product to be applied to the walls. The final result of the work depends on the quality of the paint.
A number of modern paints are perfectly applied at zero temperature and in frost, some can be applied down to -20 degrees. There is good means resistant to temperature extremes. It is important that the temperature of the paintwork material itself during operation be positive. If the material is cold, it is placed in a container in a bucket of warm water.
In the rules for the operation of the primer and paint in cold air, mandatory surface preparation is mentioned. You can not use coloring materials without certain actions:
- clean the work area from the old coating;
- treat the surface with a sandblasting machine, sandpaper or in another convenient way;
- close up irregularities with putty;
- if technology requires, carry out priming (walls should be primed if indicated by the manufacturer on the package with paint).
Can't work if it's raining or snow - you need to wait for the onset of normal weather. It is necessary to carry out staining with a roller, brush, but it is better to forget about the spray gun - its nozzle will quickly clog.
The most important thing is to make the surface clean and dry. You should also bring the enamel to the desired viscosity. Usually water-based paints are used, which are diluted with water. It must be remembered that alkyd materials sharply increase the viscosity in the cold, and do not forget to dilute and heat them up in time.
Priming work
In winter, a primer is used that is resistant to low temperatures (frost-resistant soil). If iron is stained, special phosphating compounds are used. They can be applied over rust, as they include special anti-corrosion components. Priming provides additional protection against corrosion, increases the adhesion of the final coating.
Painting the facades of the house
Carrying out exterior facade work in winter is possible with the right paint. After cleaning from dirt, dust, the walls are sanded, if there are areas of old paint or mold, they are removed. Next, the walls are primed with a product of the same brand with the main paint - this will improve the quality of the coating. They work with packages brought from the heat. As soon as the material begins to freeze, it is removed into heat, another package is taken out. The second coat of paint is usually applied after 3-5 days.
Painting bricks and surfaces with plaster
The coloring of such surfaces does not differ from that of the facades of the house. It is only important not to do the painting immediately after the masonry is completed - the work is postponed, the minimum period is a year. If you paint immediately, the coating will peel off. Surface preparation is required (cleaning with a brush from dirt, dust, mold). The chipped plaster is cleaned, the holes are sealed, and allowed to dry well. You can also fill deep holes with frost-resistant silicone sealant. After priming, the wall is allowed to dry for 5-7 days, then it is painted with a roller or brush.
Concrete processing
Concrete floors and walls have a porous surface. Also, the outer side of concrete products weather faster and the dye of the coating loses its brightness. Concrete staining can be done a year after installation, it is necessary to allow part of the concrete dust to escape. In some cases, it is possible to paint surfaces without curing - for example, in a workshop, in a warehouse, in a hangar.
Metal processing
In winter, it may be necessary to paint pipes, garage walls, iron sheathing of sheds, profiled fences, etc. The metal does not absorb moisture, so it does not change properties depending on the climate. For painting work, special compositions for metal should be used - at sub-zero temperatures they form a strong elastic film.
Tips for painting metal in winter:
- the surface must be dry, clean, free of rust with abrasive tools;
- if there is frost, the surface is treated with a flash of a gas burner - a brush or scraper will be ineffective;
- preliminarily carry out degreasing with isopropanol, acetone.
Wood painting
It is not recommended to paint wood, products from fiberboard, chipboard, lining in winter. If the house is wooden on the outside, it is better to leave its coloring until the warm season. Water accumulates between the fibers of the tree, which freezes in frost. The structure of the material expands, and the paint applied from above seals it in this state along with the ice. After thawing, the water begins to push out the paint, the latter does not stand up and goes in bubbles. Also under the enamel rotting of the tree begins.
If staining is urgently needed, a test is done first. Stick adhesive tape on the surface with a wide strip, leave for 2 days, then remove. If there is condensation on the tape, do not paint. With a dry strip, staining can be done after preliminary priming.
Painting work indoors
Painting a house inside during cold weather is much easier than doing outside work. But the specifics of painting must be taken into account.
Balcony
Painting a balcony or loggia in an apartment in winter may be required during the sale to improve the surface of walls, ceilings, and floors. The most difficult thing is to tint a cold balcony - it is better to wait for the positive temperature and only then carry out painting work. If absolutely necessary, you can purchase paint that can withstand low temperatures, wait for a sunny day, make sure that the walls of the loggia are warm enough, and paint.
Staining is carried out only in the morning - the coating will dry faster due to the warming of the sun. If there is an outlet, you can take out a heater to the insulated balcony, this will allow you to carry out work efficiently. Good for balcony acrylic water-based formulations- with their use, poisoning can be avoided, they are environmentally friendly, odorless. These colors enhance thermal insulation characteristics walls, allow them to "breathe", fade and collapse very slowly. If there are plastic or metal parts on the balcony, it is better to varnish them. The lining is covered with acrylic varnish.
Batteries
Painting a battery in winter has a number of features. To paint the radiator, you need to prepare a brush with metal bristles, brushes - simple and radiator with a long handle. You will also need sandpaper, a dusting brush, a knife. Be sure to purchase a primer for metal, paint, solvent. The basic composition must necessarily be suitable for radiators and contain anti-corrosion additives, be non-toxic. Best suited means:
- acrylic;
- alkyd;
- water-dispersion;
- silicone;
- based on heat-resistant varnish;
- zinc.
How many degrees can these enamels withstand? They are designed for a standard temperature of +80 degrees. Some are available in aerosol form - they are sold in a spray can, and even the most inaccessible places can be easily painted by spraying. Batteries for painting are best removed by shutting off the water supply. If this is not possible, it is worth waiting until the batteries are turned off in the spring. Hot batteries will be painted poorly, the coating will often swell. After cleaning the surface, it is primed, sequential painting is done in 2 layers. Each layer must dry completely.
Window
Painting wooden windows in frost outside is undesirable, as well as other wood products. Only the use of heat guns will make it possible to dry the product well, but the complexity of the work will increase significantly. From the inside, painting is carried out in the same way as it is done in warm weather. old paint need to be removed, primed the surface, then apply suitable composition. Plastic windows you can also paint with special paints if you want to update their color.
What colors are used in winter
Enamels and primers, which are used at low temperatures, are diverse. Their properties:
- do not freeze in the cold;
- suitable for different types materials;
- can be operated at temperatures up to -10 ... -20 degrees;
- form an elastic layer;
- Dries faster than regular paint.
Water-based paints
This type of paint is most in demand in winter. Very popular are the products of Dufa and Batilith, Dulux and Tikkurila, which produce many types of corresponding paints and varnishes. Good frost-resistant paints are produced by the German company Caparol. A number of manufacturers produce frost-resistant water-based paint AK-115, which can withstand up to -20 degrees below zero. Other known materials:
- parade f20;
- Lacra;
- Alpa Façade;
- primer Brite Professional;
- Vincent Muralith F1.
Oil paints
Oil materials are now almost not used. In terms of properties, they are much inferior water-based paints, their service life is not more than 2-3 years. It is necessary to dilute the funds with drying oil, special solvents. Only some paints marked PF, MA, GF are suitable for working in the cold.
Aerosol paints
Enamels in cylinders are used, for the most part, for painting batteries, cars, plastic products. They are quite expensive, but they create a high-quality coating. Popular brands are:
- maxi color;
- Colomix;
- dupli color;
- vixen.
Most paints of this type can be used down to -15 degrees.
Storage temperature of paints and varnishes
Usually allowable temperature storage is indicated on the packaging of the material. According to GOST, paints and varnishes can be stored at a temperature of -40 ... + 40 degrees, but individual conditions may exist for each specific material.
