How to treat larch decking boards. How to cover a larch deck board? How to paint a larch house

Let’s immediately answer the question of what planken is: it is a finishing material that is traditionally made from Siberian larch. Since the products are made from this type of wood, they have a mass unique properties, which are typical specifically for larch.

Among all positive qualities one can note the resistance to various atmospheric phenomena, taking into account our climatic zones - thanks to this larch plank can be safely use not only indoors, but also directly outdoors.

Planken is very beautiful, and at the same time natural. With its help, you can radically transform the interior of your room or the architectural appearance of the entire house. Due to the fact that the material very naturally imitates timber (almost 100%), even a modest cottage house made of SIP panels or lightweight concrete structure you can make it look real wooden house, which looks very status.

How to paint and protect larch planks? All serious manufacturers have recommendations - what, in what sequence and how much to apply to the surface to be treated.

The simplest and reliable option DIY is an alkyd system of transparent (glazing) products: antiseptic primer - protects against fungus, mold, does not form a film and finish (Sikkens) - transparent semi-matte coating containing an internal UV filter, which enhances the protective properties of the coating.

Now in more detail for professionals.
The general universal recommendation has the following sequence: primer-color-intermediate sanding-finishing coat.
All finishing coatings are divided into two large groups: solvent-water and solvent-organic. Ideally, the entire line of materials is based on one binder. The second important choice is an opaque (completely covering the texture of the wood) paint and varnish material or a glaze (emphasizing the texture of the wood).
wood) coating. The first one is 2 times more durable. But with water-soluble materials there can be problems. Water dissolves salts in larch, which have an acidic environment, and reddish spots may form. In extreme cases, rapid detachment occurs. Plus resinousness, which, as a rule, prevents impregnation aqueous compounds. As a result, there is the same violation of adhesion and spotting noticeable in area due to different absorbency of the surface. Therefore, alkyd-based materials are better suited for painting this type of wood.

Now let’s determine the quality of painting with glaze materials on a large surface. If the wood of one board out of a hundred initially differs in tone from the rest - what is the solution? The first thought is to apply another coat of paint. Will this solve the problem? - no, it won’t, because due to the transparency of the paint and varnish material, what was light will become a tone darker with the second layer, and what was dark will become even darker, so it will not be possible to even out the difference in tone with glazing materials. The absorbency of boards can also be different due to different densities. And the original color of the board varies significantly, even in boards from the same trunk, from amber to red. Therefore, when painting larch products with glazing materials, you must either select boards that are approximately the same tone, or use opaque paints and varnishes.

At the House of Paint you can choose any system of wood protection and coloring: organic ( alkyd materials) glazing products: antiseptic primer - s Protects against fungus, mold, does not form a film and finish (Sikkens) - a transparent semi-matte coating containing an internal UV filter that enhances the protective properties of the coating. But if the solution to paint wood without preserving the wood texture is more suitable for you, then you can use opaque materials: opaque priming , with excellent adhesion -(Sikkens) - And semi-matte finish, highly scratch resistant (Sikkens).

If we talk about water glazing products, we recommend professional materials: antiseptic primer (Sikkens) provides effective protection from blue rot and finish (Sikkens) - semi-matte coating with high UV protection, retains elasticity over a long period. If your choice fell on opaque water-based materials, then we offer a painting system: primer (Sikkens), which dries quickly and has excellent adhesion to wood, and finish (Sikkens), a matte finishing coat with high degree scratch protection and other
m mechanical influences.

Another useful advice: on new wooden surfaces, after applying water-based materials (primer or impregnation), pile rises. If it is necessary to obtain a perfectly uniform surface, then after the applied primer layer has dried, it is necessary to carefully sand the raised pile; it is available in two versions - gray (fine abrasive) and red. This abrasive allows you to remove only the lint without damaging the applied coating. Then you can apply the next layer of paint material.

I would like to say a few words about the oil, which is also popular now. According to professional technologists, it is better not to use oil on the facade or to choose wood for this system that is least susceptible to rotting - larch, oak, teak. Any oil manufacturer recommends updating the coating at least once every 1–2 years, and this is quite labor-intensive. Sikkens alkyd-based wood preservatives are recommended to be renewed after 5–7 years, depending on the climatic conditions the area where it is located wooden house, and on water based every 3–5 years.
Recommendations regarding the so-called “Yacht” varnish. It should not be used for painting outside; the reason for its failure is that it is a hard, durable, inextensible coating, and wood is “breathable”, i.e. the structure changing its volume - as a result - a bursting, flaking, coating that eventually develops and a hellish job of continuous sanding.

Treated with professional Sikkens paints and varnishes, the wood acquires a very important property, namely resistance to fading, since larch turns black in the open sun. In addition to protecting the wood, which gives the product the necessary properties, color is also important paint and varnish materials, which will help give the wood the desired shade. Our qualified specialists will help you choose effective system protection, decide on color scheme and, if required, they will make an individual color selection based on your sample.

Practice shows that in ANY house or bathhouse there are places or structures for the manufacture of which it is desirable to use wood species that are especially resistant to decay. Usually these are FLOORS in the house, floors of open vernades, terrace boards, boards on open or closed veranda under a canopy or deck board, solid wood floor boards used in damp places, near swimming pools, in baths, steam rooms, saunas, etc. To reduce the risk of damage to the floorboard and extend the time efficient work From the moment of laying the floor to updating the floor covering, it is possible and recommended to use larch boards and floors. Larch wood is particularly resistant to damage from moisture and does not rot for a long time. It is even used to make a backing beam, backing board or lower crowns wooden house, on which a frame made of pine, fir, aspen, etc. is laid. But having chosen larch as a building material or made larch floors, we may be faced with the task of selecting the final protective impregnation for a given type of wood, i.e. how to paint and treat the larch floor. The thing is that it is difficult to apply varnishes and paints to larch wood and lumber due to its specific properties - natural oiliness, which prevents the “sticking” of surface paints and varnishes, and quite high friability, which affects the degree of change in the geometry of the board when humidity changes treated wooden surface. Conventional varnishes and paints practically DO NOT stick to larch floorboards or protective coating, treated with varnish and wood paint on larch turns out to be NOT durable at all. It is safer to treat larch floors with impregnation, which does not peel off, does not form a hard surface film, but protects the wood from moisture and allows the wood to “breathe”, i.e. OIL and WAX.

Impregnation for floorboards and larch floors

Treating larch with OIL and WAX for wood is IDEAL option when choosing impregnation for floorboards and larch floors. It is NECESSARY to protect larch floorboards, because... although wood of this species is least susceptible to rotting and is quite durable, but like ordinary wood it can DARKEN, or rather acquires a dark brown color, gets WET, absorbs MOISTURE, swells and deforms. In addition, you want to preserve the natural structure and color of fresh wood or give wooden floor shade of more valuable types of wood, for example the color of NUT, OAK, BEECH, wenge, etc. If in this case, for larch floors or floors in baths, saunas, steam rooms and washrooms, VARNISH or paint cannot provide high-quality protection, then a RELIABLE protection option can be treating boards, timber, interior elements with Wood Oil, Liquid or Solid Wood Wax , Oil with wax, Oil with wax impregnation for floorboards, parquet or parquet board, both inside and outside the house and even if the floor boards of the open veranda are processed.

If your country house is not heated regularly, heating of the house occurs seasonally, with breaks for a relatively long time, during which the temperature in the room can fluctuate significantly if the room is subject to changes in humidity, humidity changes or if you install a heating system in the house wooden floors, then the choice of impregnation for processing wooden walls, ceilings and floorboards or parquet should be in favor of floor oil and parquet oil, oil with wax for flooring, as well as wax for floorboards or wax for parquet. This choice is obvious, because The use of varnishes when treating heated floors can lead to rapid peeling, cracking and peeling. Peeling of varnish and paint can occur due to a fairly rapid change in the geometry and volume of the parquet lamellas or a completely imperceptible deformation of the floorboard, expansion or contraction of the floorboards due to a rapid change in temperature when they are heated, followed by cooling and cooling. To solve the problem of how to treat a heated wooden floor, consider wood oil or wax for floors and parquet.

The ideal condition and well-groomed appearance of the flooring, as well as the floors in the house, can be ensured by oils, waxes and your attentive participation and careful attitude towards wooden surfaces from natural wood. Choose oil and wax impregnations specially adapted for these purposes for floorboards and heated wooden floors.

Painting planken

If the task is to change the natural color of wood, painting the plank is a mandatory technological operation. In addition, planken made from natural wood requires mandatory processing. protective compounds due to the characteristics of the “living” material, its susceptibility to rotting, damage by fungi, mold and insects.

Even larch, ash and thermowood, which are relatively resistant to environmental influences, will retain their strength and durability much longer. spectacular look, being processed. Thus, painting plank accomplishes several tasks, not just changing the color of the wood.

The most popular materials for processing façade plank, lining and other finishing materials made of wood:

Varnishes: alkyd-urethane, polyurethane, water-based acrylic.
Antiseptic impregnations, aqueous and organic solvents.
Oils and oil waxes (compositions based on natural oils with the addition of beeswax or carnauba wax).

According to the degree of hiding power (opacity) of the finish, materials are divided into:

Covering (covering).

They form a dense, opaque film, these include paints and enamels.

Glazing.

Creates a translucent coating. Includes impregnations, stains, tinting varnishes, tinting oils and waxes.

Colorless.

Completely transparent compositions: varnishes, antiseptics, oil and wax.

The choice of processing agent is determined by what end result the customer needs. In this case, it is necessary to take into account the characteristics of the chosen finishing material: resistance of the coating to water and sunlight, ease of cleaning and, if necessary, restoration of the coating.

Varnishes and paints

Treating outdoor planks made of larch, pine and other materials with paints or varnishes involves preliminary impregnation with antiseptic primers. The film of varnish or paint that forms on the surface of the wood is resistant to moisture and ultraviolet radiation, however, if damaged, the defective area will need to be thoroughly sanded and repainted, which is not always possible to do on your own.

Impregnations

Modern professional impregnations, especially the so-called “glazes,” are applied in two or three layers and do not require additional coating with varnishes. The intensity and coverage of the color varies by the number of layers applied. Impregnations penetrate deep into the wood, can be used without prior priming with an antiseptic (if specified by the manufacturer) and are resistant to aggressive influences. Damaged coating can be restored relatively simply, without special equipment.

Oils/oil waxes

When painting planken with oil, the composition deeply saturates the wood without forming a noticeable film. After polymerization, the surface becomes harder and more resistant to impacts, and has excellent resistance to sun rays and water. If necessary, it can be restored by wiping the damaged area with a rag moistened with the same oil or wax with which the planken was originally treated.

Due to the ease of application and subsequent care of the product, as well as the ability of oils and waxes to effectively emphasize the depth of texture and natural beauty of wood, the demand for these materials is increasing. "Planet Lesa" paints planks with waxes and oils in the workshop using its own multi-stage technology, which will ensure the beauty and durability of the coating on your facade.

Specifics of painting planken

When installing planks, gaps are left for ventilation and compensation for wood expansion; accordingly, each plank should be processed on all sides before installation. To save material, it is permissible to limit yourself to one layer of protective coating on non-visible surfaces.

Factory planken is supplied sanded and ready for painting, but additional sanding with a fine-grained abrasive will remove minor transport defects and improve the final result. The same applies to brushed (aged) planken.

If you don't want to bother with painting by yourself or are planning to install a façade or interior decoration premises in winter, you can buy already painted planken boards. It is impossible to achieve the same quality as in a workshop manually. The price of such products is affordable, and allows you to save on your own labor costs and the purchase of painting materials. In the near future we will try to post a video of painting planken in our production.

If you have a need to make a strong and durable covering on a loggia, porch or on an area under open air, then you need a material that is resistant to various types of weather conditions. One of the best options- This is a board made of larch.

Altai larch is considered the most popular species construction wood, thanks to its high consumer properties. It is necessary to note such qualities as resistance to destruction caused by atmospheric conditions. It resists rotting several times longer than pine. This material has been used in construction for a long time and is in demand for good reason.

Features of larch

High durability is due to the unique characteristics of wood:

In density and hardness it is second only to oak;
Very high resin content;
Special resin composition;
High resistance in humid environments.

For a long time in the Urals and Siberia, houses were built only from larch. Churches, barns and similar structures, lined with boards made of this wood, have been standing for more than 300 years. Long-lasting railway sleepers and the piles on which Venice stands are made from this type of wood. And this is the best proof of the durability and practicality of wood.

Boards made from huge tree trunks are ideal for constructing open terraces, gazebos, playgrounds, patios, all kinds of stairs, piers and paths. Designers are also happy to use this material for landscaping. In most cases, deck boards are used, which are also called “deck boards”. Its purpose is structures in open space.

Mechanical processing of wood, with all its complexity, allows you to obtain precise dimensions and smooth surfaces boards. Grooves 2-3 mm deep are cut on one side. On the other side there is a deep groove that serves for ventilation and water drainage. But still, for greater durability, appropriate treatment is needed against rotting and damage by various bugs.

Causes of wood destruction

Perhaps the main reason for the destruction of any wood is climate. Seasonal changes have an adverse effect on larch products. Over the course of a year, the material is subjected to heavy loads, consisting of:

Direct rays of the sun;
Dampness;
Sudden changes in temperature;
High humidity;
Excessive heating.

Ultraviolet radiation has a detrimental effect on wood. It loses color and acquires gray shade, the protective properties of the resin are destroyed. In wet weather, wood absorbs moisture and releases it when dry. When these processes are uneven, they can cause the material to warp. High humidity can lead to rotting. However, with direct exposure to sunlight, moisture evaporation occurs unevenly. The top layer dries out, but the bottom layer remains damp, which causes cracks to form.

Deck boards made from larch are also at risk when outdoors. They are divided into several types:

Climatic (in the form of precipitation, temperature changes, ultraviolet radiation);
Biological (fungus and mold damage);
Mechanical (formation of potholes, scratches, abrasion).

But one of the most hazardous factors– a sharp change in temperature. There may be frosts at night in spring and autumn, and in daytime the temperature rises to 15-20°. If the wood is not treated with protective ingredients, then at temperatures below zero, moisture crystallizes directly in the fibers and then freezes. This leads to the formation of cracks, splits and warping of the material.

Processing methods

Now it's time to figure out how and with what to protect terrace board so that it maintains its reliability and does not lose attractive looking throughout the entire service life. Despite the fact that larch flooring elements are most often supplied to the buyer already treated with appropriate compounds, it is still necessary to update the protection at least once a season. Today there are many technologies that protect wood from various destructive factors.

Coloring

Coloring allows you to create an attractive appearance, which is an important component in production. construction work. The paint must be oil based. It is ideal for protecting terrace structures. Coating in several layers will completely hide possible flaws. Along with this, a special glazing paint is produced, which does not hide the texture of the wood, but gives it an even more distinct appearance. You can paint in 2-3 layers using a regular brush. It is advisable to carry out coating with coloring compounds in the fresh air.

Vacuum processing

Vacuum processing is usually carried out under special conditions. It allows you to improve the quality of the material:

The resin evaporates and dries;
The color is saturated;
Thermal conductivity indicators improve;
Density increases;
Moisture absorption decreases;
Increases resistance to fungal infections;
Resistance to deformation increases.

Heat treatment

If you treat the decking board on special equipment, then the material practically loses moisture and becomes suitable for the construction of buildings near water (piers, pool framing), and interior decoration.

Chemical treatment

This method is intended to protect the material from biological threats. The industry produces enough preparations for wood treatment. Some are water-based (leachable), while others are made from an oily organic compound (non-leachable). Do not forget that impregnation for such protection should be carried out several times a year.

Important! It is recommended to treat decking boards outdoors, with minimal air humidity. First you need to remove all dirt, and then cover it with several layers. protective agent. Timely care the material will allow you to maintain the color palette and reliability of the coating.

Materials used

Like any tree, larch from time to time needs preventive treatment against rotting, fungi and other destructive factors. The selection of products should take into account their purpose, properties and frequency of application. There is no need to skimp on protective drugs. Caring for wood begins even before installing the decking board.

The following types of compositions are used:

Antiseptic – provide protection against fungus;
Fire retardant - increase heat resistance and fire resistance;
Paints and varnishes protect the wood from loss of color and increase its aesthetic appearance.

Antiseptics are made on the basis of waterproof and water-repellent compounds. They are designed to protect larch products from fungal infections and insects. Often a tree turns black when outdoors. An antiseptic can easily cope with this problem. This impregnation is divided into several groups:

Water-soluble emulsion;
Oily coatings;
Antiseptics based on organic solvents;
Combined formulations.

Fire retardant is a special solution that prevents fire. Treatment with this composition gives the wood fire resistance and resistance to fire. When the combustion temperature is reached, the fire retardant foams and forms a heat-insulating foam suspension that protects the wood from ignition.

Varnishes and paints are used to process wood intended for interior decoration. But before applying paint coating it is necessary to treat the board with a filler, which provides an additional protective coating. Wood intended for outdoor use is impregnated with primers, glazes, oils containing linseed base, and emulsions containing beeswax.

Natural materials used for finishing flooring, have always been valued for their high qualities, environmental friendliness and practicality. Particularly popular among them is larch, used to cover the floors of terraces and verandas. Painting larch deck boards - important point during operation and maintenance. The question of how to treat or open a larch floor for maximum protection is faced by every owner. country house or dachas who decide to use this material.

Features of larch flooring

Larch is a hard type of wood that can withstand heavy loads. In terms of strength, it is not inferior to oak, and the presence in the composition large quantity gum (resins), provides larch with hardness that increases over time and does not expose the surface to moisture.

How to choose the right larch for building a floor on a terrace or open area shown in the video:

The advantages of installing larch flooring include:

If properly cared for, a terrace with a larch floor will last for decades, delighting owners and guests with its beauty and elegance.

Important! To extend the life of the terrace flooring, you should regularly paint larch decking boards with compounds specially designed for this purpose.

Factors that destroy wood flooring

The most dangerous thing for a wooden surface is the wrong climate. environment, which includes temperature fluctuations, high humidity or too dry weather. In addition, when the decking is constantly outdoors, during the year its surface is exposed to such unfavorable factors as:

Direct sunlight;
Water and snow;
Sudden temperature changes;
Temperature too high or too low;
Dampness.

All these factors provoke destruction wooden covering, the composition of its surface structure is disrupted. It loses its natural color, becomes gray, and the resins that provide protective properties are destroyed. When the humidity level changes, the wood becomes saturated with water, and when the temperature rises, evaporation occurs. Moreover, the liquid begins to evaporate first from the surface, but inside the boards remain wet and begin to undergo destruction.

The wood on the surface of the larch begins to crack and become covered with fungus, eventually becoming completely unusable.

All harmful effects can be divided into three types:

Climatic;
Biological;
Mechanical.

Attention! The most dangerous impact is the formation of condensation on the surface of larch due to temperature changes. It quickly renders the tree unusable.

Materials and methods of processing larch floors

To protect the larch decking from various types negative impact is used as various technologies, and materials. The most common ones are listed below.

Coloring

To treat larch, a special glaze paint is used, which is a translucent composition that simultaneously performs the function of both decorating and protecting the wooden surface. When applying such a composition to a textured surface, it provides it with smoothness; on a plastered surface, on the contrary, it creates the appearance of volume and relief.

Glazing compounds for oil based provide the coated surface with properties such as:

Protection from moisture and temperature changes;
Wear resistance and protection from mechanical damage;
Safety.

Attention! One of the main disadvantages of such material for the surface of a terrace board is long term drying of the layers, which is usually about 1 day.

Glazing paint gives larch a more distinct textured look, while hiding possible flaws.

Vacuum treatment

This method of surface treatment is carried out under special conditions and contributes to an effect that is designed to endow the material with the following properties:

Evaporate and dry the constituent resins;
Get rich color;
Improve the thermal conductivity of the material;
Increase density;
Reduce the ability to absorb moisture;
Increase protective properties against fungal penetration;
Increase resistance to fungus and mold.

Heat treatment

Processing larch at high temperatures using special equipment allows you to minimize its water absorption capacity. This type of surface treatment of the material is most in demand for the construction of structures near water, swimming pools and other places with high humidity levels.

Chemical treatment.

This type of treatment protects the coating from biological threats. Variety of options available on the market building materials involves the use of either water-based substances (wash-out type) or oil-based preparations (non-wash-out impregnations).

Important! Processing by any of chemical compositions Manufacturers and builders recommend cleaning larch surfaces several times a year, during periods of particular activity of insect pests.

Processing should be carried out at minimal air humidity and in open space. First, remove any existing contaminants from the surface and apply several layers of the chemical.

Materials for processing

An important step to ensure effective and long term service of larch decking is the use of antiseptic impregnations that protect the wood from mold and mildew.

Important! Although decking boards are treated with an antiseptic at the factory, it never hurts to treat the material yourself before installation.

The ends of the boards are covered with wax emulsion impregnation, antiseptics are applied to inner part boards, and the top coating is treated with various oils, paints or varnishes.

The following protective compounds used for decking boards are distinguished:

Antiseptic- protecting against mold and mildew;
Fire retardant - providing high level fire safety;
Paints and varnishes - increasing aesthetics appearance and protection against color loss.

Among the varieties of antiseptic compositions for larch, the most popular preparations are water-soluble emulsions and oil compositions. Sometimes organic solvents, as well as combined formulations, are used as antiseptics.

Fire retardants used to increase fire resistance when the ambient temperature rises to the maximum acceptable values begin to foam and form foam on the surface of the boards, protecting the coating from fire.

Among paint and varnish products, intended for wooden surfaces, terrace oil is especially popular, which emphasizes the natural structure of larch and reliably protects it from all types of threats. The market offers a wide variety of materials of this type, with different additional functions- tinting effect, anti-slip effect, antibacterial type and containing wax, which provides maximum moisture resistance and protection of the surface from precipitation.

Yacht or front view of this composition. Yacht varnish increases the wear resistance and strength of the floor covering, while facade varnish is more flexible and reliably protects against any deformation. The choice should be based on the operating conditions of the larch floor.

Used for protection and various paints for outdoor wooden surfaces. They can be made based on:

Oils or alkyd resins. Their use is advisable when the floor has already been covered with a composition of a similar type;
Water-based acrylic components. They are not afraid of atmospheric influences, both temperature and humidity changes;
Polyurethane. Creates a durable film on the surface with a high degree of wear resistance;
Latex. They are odorless, remain on the surface for a long time and allow the wood to breathe.

Conclusion

Larch - excellent material for the manufacture of coverings for wooden terraces and other structures in open spaces. In order for the larch structure and surface to last a long time, it should be periodically treated with protective compounds, and also proper care behind the coating, applying special means and specialized compounds.
