Acrylic sealants: characteristics and applications. Which sealant to choose: silicone, acrylic or polyurethane

Sealants are called building materials, the main purpose of which is to fill various voids. At the same time, due to the special properties of the composition, the solidified mass protects objects from the penetration of cold and moisture, as well as from foreign objects entering holes and crevices. Insulating products are produced in the form of a pasty or viscous substance. The scope of acrylic sealant depends on the basic composition, but for the most part, these products are considered universal. The service life of almost all sealants is estimated at fifteen years or more. The article will discuss how to choose an acrylic sealant.

The main effect of acrylic sealant occurs after the polymer (or oligomeric) base begins to harden (and sometimes as a result of solvent evaporation), that is, the vulcanization process occurs. But there is also such a variety of mass, which throughout the entire service life remains in the form of a non-drying putty.

Modern repair and construction works are practically unthinkable without the use of sealing compounds at a certain stage. Indeed, it is thanks to them that it is possible to easily and without subsequent problems close up joints in any structure or achieve a hermetic connection. Materials are used both in home repairs and in professional construction.

Main Features almost all types of sealants can be called:

  • good and reliable adhesion to any materials;
  • elasticity and plasticity of the applied layer;
  • resistance to high temperatures and various atmospheric phenomena;
  • safety and environmental friendliness for both humans and environment.

Although almost all products can boast of these properties, their widest range is still on the market, which means that in order to make the right choice, you should familiarize yourself with these materials more thoroughly.

General information about sealants

First of all, it should be said that sealants are divided by composition. So, depending on the presence of certain components in the base, they can be:

  • acrylic (based on acrylic acid);
  • silicone (the main ingredient is silicone rubber, used for sealing joints in wet rooms, for glazing windows and balconies, for mounting polycarbonate structures, insulation of boards and various components household appliances and so on);
  • bituminous (bitumen-based, used for sealing roof structures, seams in the chimney, joints on the plinth or foundation);
  • butyl (butyl is used as the basis, most often such a product is used in the manufacture of double-glazed windows);
  • polyurethane (based on a highly elastic polymer - synthetic elastomer, used for bonding materials and sealing joints and seams between them, for example, wood, metal, ceramics, concrete, brick, and so on);

  • thiokol (based on polysulfide rubbers, used in professional construction for sealing interpanel and interblock seams and joints, as well as in window structures);
  • MS - polymeric (based on modified silicone, has wide range applications, due to high adhesion with most popular building surfaces).

The most common types for general purpose of all the above products, silicone and acrylic products are considered. The difference between them is that acrylic sealants do not have a sharp specific smell, and, in addition, their further coloring is allowed. Also, in terms of price, acrylic products are cheaper than silicone ones. It is worth saying in more detail about their main differences.

How is acrylic sealant different from silicone

  • Despite the fact that silicone sealant is the most popular type of product for grouting and various cracks, all the same, acrylic products compare favorably with them. Of course, as noted above, first of all we are talking about a lower price and the possibility of coloring the finished layer.
  • Also, although acrylic is inferior in moisture resistance to silicone, special antifungal and antibacterial components are added to its composition, thanks to which any dampness is not terrible for the applied seam.

  • Besides, acrylic materials easy enough to renew, which is almost impossible to do with silicone compounds. If you need more serious protection, you can purchase special acrylic sealants with water-repellent properties by adding silicone as ingredients.
  • Well, comparisons in terms of aesthetics will also have an advantage with acrylic sealants, since they create a transparent layer on the surface, while silicone has the appearance of a noticeable white stripe.
  • The main thing to remember when using certain materials is that they have preferred applications.

The main characteristics of acrylic sealant

Acrylic sealant is usually called a composition based on acrylic acid, or based on acrylate. The main purpose of such products is to connect and seal inactive or fixed structures. The insulating effect begins to appear after moisture evaporates from the surface of the applied layer.

Most often, such a sealant is used to seal cracks, seams and joints in a stone or concrete surface, cracks between cracked boards, a gap between a wall and a window sill, or between a wall and a door frame.

Composition of acrylic sealant something like this:

  • acrylic emulsion;
  • titanium dioxide;
  • calcium carbonate;
  • special plasticizers;
  • various additives.

Advantages of acrylic sealant:

  • ease of use;
  • it is allowed to paint the finished layer, as well as to plaster;
  • during operation does not emit toxic chemical elements, that is, it is safe for humans and the environment;
  • there is no need to ventilate the room during the application of the product;
  • non-combustible material;
  • acrylic sealant can be selected in the desired color;

  • it will also not be difficult to buy products for a certain type of material, for example, a special acrylic accent sealant is sold for wood.
  • relatively low cost.

Of course, despite all the advantages of such products, it also has its own significant limitations:

  • loss of elastic properties at low temperature;
  • the product is ineffective in conditions constant contact with water;
  • limited service life;
  • may change color upon drying, for example, krass acrylic sealant acquires a yellowish color.

Manufacturers of modern products are trying to improve the quality of their product by adding various elements to the composition that can increase the period of operation of the sealing layer and significantly increase resistance to deformation.

Specifications of acrylic sealant

  • Recommended application parameters: the width of the joint can vary from 6 mm to 5 cm, while the thickness should be within 1/2 of the width. If the seam has a size exceeding 6 mm, then it is best to use a special sealing cord (diameter 6-50 mm);
  • acrylic sealant consumption: consumption of 1 pack of material for standard application (joint 1 cm wide and 0.6 cm thick): containers with a volume of 22 kg are enough for an area of ​​up to 300 running meters; tuba, with a volume of 325 ml, can be sealed up to 5 linear meters;
  • surface temperature during application: from +4 to +32 degrees;
  • ambient temperature: from -40 to +120 degrees;
  • painting: it is allowed to paint the finished layer with latex paints, after 21-30 days after applying the sealant;
  • hardening time: with a joint thickness of 10-12 mm, the layer will harden within 21-30 days, while maintaining the temperature within 20-25 degrees and humidity at 50-60%;
  • setting time with the surface; up to 60 minutes;
  • frost resistance: withstands up to 5 freeze / thaw cycles (at a temperature of -15 degrees);
  • elongation at break: 550%;
  • does not tolerate moisture well, if it is necessary to work in wet weather, then the outer layer should be covered with polyethylene, it is not recommended to apply it to surfaces that are constantly in the aquatic environment;
  • packaging: cartridge, tubes, plastic bucket or tubes;
  • shelf life: unpacked, it can be stored for 12 months from the time of packaging, at a temperature of +20 degrees.

So, acrylic sealant is a viscous mass designed to fill various voids.

The main characteristics for which this product is purchased are:

  • high strength;
  • resistance to deformation;
  • excellent adhesion to most surfaces;
  • elasticity.

At the same time, a good sealant must fully retain its physical, chemical and mechanical properties during operation, and also not emit toxic substances i.e. be safe.

Commercially available products are divided into one-component, two-component and multi-component formulations. If the product is ready for use immediately after purchase, it means that it is based on one specific component, but if the mass should be mixed before use, then this is a polycomponent sealant.

Acrylic sealants are most often used to bond wood, brick, stone, plaster and drywall surfaces together. They are also used to seal seams and cracks in inactive structures located indoors.

How to apply acrylic sealant

  • For the use of one-component acrylic products are not required accessories and knowledge of some special rules. Products are odorless, do not irritate the skin, so you can apply even without using gloves and other protective equipment. In addition, even if the composition gets on the skin, it is easy to wash off with a simple warm water until the sealant is dry. The same goes for the instruments that interacted with the mass.

  • Of course, when sealed various surfaces some important rules. So, if the sealant is used in the bathroom, then before you start using water, you must wait for the top layer to harden, otherwise it may blur.
  • If this is not suggested by the instructions, then it is not recommended to dilute the composition with water or a chemical solvent. The process of polymerization (that is, curing) occurs in two stages. First, a film appears on the surface, which, although strong, allows for some adjustments, this phase takes 1-3 hours (depending on environmental conditions). At the second stage, the final solidification of the mass occurs, and this process can last several days. At this time, it is advisable not to touch the applied layer and not expose it to moisture.
  • To apply the sealant, you should use a special gun (when packaged in foil tubes or a cartridge) or a spatula (when packaged in plastic buckets), but if the mass is sold in the form of tubes, then it is simply squeezed onto the seam. The applied layer should be given the required shape within 10 minutes, since in the future the formation of a film will begin and it will be problematic to correct the seam.
  • When opening the package, it is optimal to immediately use the entire product, otherwise in the future it will lose its main qualities.

How to make the right choice

  • When choosing a sealant, one should proceed from what materials it is needed for. Thus, plastics (for example, polycarbonate, teflon, polyvinyl chloride, or polyethylene) have minimal adhesion to sealants. Therefore, in order to increase adhesion with such a surface, it is recommended to purchase specialized sealants or additionally use primers that create an intermediate layer and contribute to a reliable and durable connection of various surfaces.
  • When applying a sealant in an aggressive environment (high humidity, sharp temperature fluctuations), you should buy products with fungicides in the composition. Just remember that they are suitable for areas such as a bathroom, pool or balcony, but it is not recommended to use them in the kitchen, especially in places that come into contact with food.
  • Acrylic sealants for aquariums are highly resistant to aggressive environments, but are safe for living organisms. In addition, they have increased tensile strength. Therefore, if there is a need to isolate the seams in a home aquarium, then it is necessary to choose just such acrylic compounds.

  • When there is a need to seal joints in materials with elevated temperatures, then the sealant should be purchased with an acceptable operating temperature not less than +300 degrees. Only in this case it is allowed to seal cracks or seams in stove and fireplace structures and not be afraid that the composition will lose elasticity or collapse under the influence of heat. Now you can find sealants that can withstand temperatures up to +1500 degrees and are fire resistant.
  • Acrylic sealants are not recommended for external sealing of windows or double-glazed windows, as well as in places where there is frequent contact with water or chemicals.

AT construction stores you can also find acrylic sealants produced by other manufacturers. In this case, be sure to pay attention to the composition of the product and the expiration date.

It is also not recommended to choose goods of unknown brands at too low a price. Some manufacturers, in an attempt to reduce the cost of their products, significantly change the composition or use low-quality raw materials, as a result of which the sealant loses its basic properties. Therefore, it will be optimal to purchase goods from trusted manufacturers and suppliers.

Sealing joints during construction and repair is a common problem. It is not only sealing sinks, bathtubs and shower tray, for which sanitary silicone bathroom sealant is used, but also various cracks and seams. In most cases, universal silicone or acrylic sealants perform well.

How to choose a sealant for cracks in the wall? A common problem is the choice - silicone or acrylic. What to choose for the bathroom and can acrylic be painted? What sealants are best used for outdoor work? These questions will be discussed in the article.

Acrylics and silicones are often confused by people who have little experience with building chemicals. Both products are usually bought in tubes, which are used with special guns. However, you should carefully consider which product to choose - acrylic or silicone and what is the difference between them.

This auxiliary building material is quite popular and has a wide range of applications.

Silicone sealant has a fairly wide application:

  • for filling and sealing seams,
  • door frames,
  • window sills,
  • cracks in the floor
  • seams in tiles
  • bath and shower joints with tiles.

Acrylic joint sealers can perform some of these tasks. It all depends on the operating conditions.

What is the difference between acrylic sealant and silicone sealant?

Silicone sealants for seams allow simultaneous sealing and joining of two materials. They can be used for most building structures and equipment such as ceramics, glass, stone, wood, sanitary ware, etc. Depending on the type of elements to be joined, the correct type of silicone should be selected.

Advantages of silicones:

  • high elasticity,
  • resistance to sub-zero temperatures.

Depending on the type of silicone, they are more or less resistant to moisture and mold. Unfortunately, a serious disadvantage of silicone is the inability to color it. Although colored silicone sealants can be found on the market, for example for ceramic tiles and porcelain stoneware, but their color does not always meet our needs.

Acrylic sealants mainly used for sealing and filling gaps inside the building. Apart from a few exceptions, acrylics should not be used outdoors because this material is not resistant to low temperatures. winter temperatures and can quickly crack.

Like silicones, modern quality acrylic sealants are also flexible and suitable for most common building materials. They should not be used, however, if in addition to sealing gaps, we need to firmly and permanently glue the elements - silicones are much better suited for this purpose. An important advantage acrylic fillers is that they can be painted with any paints, both traditional and decorative. Acrylic sealants are also available in a painted version.

Acrylics are mainly used for sealing:

  • ceramic materials,
  • concrete,
  • drywall,
  • can be used in sealing glass and steel.

However, acrylics should not be used where cracks are subject to prolonged contact with moisture - sanitary silicone is used to seal such places.

Acrylic sealants

Traditional acrylic caulk is commonly used to fill joints in plaster and can be painted over. There are also special acrylics on the market, which form the best surface for painting, because thanks to the special composition, the adhesion of the paint is increased. Such acrylics do not cause discoloration of the paint.

Acrylic sealants harden much faster than silicone, but have less elasticity, so it is recommended to fill them with joints and cracks no wider than 15 mm.

You can also purchase special acrylics for plaster, which include a number of minerals in their composition, so that they bond better with such a surface.

Acrylic sealants for outdoor use

In some cases, it is necessary to use exterior sealants, which we can also paint or plaster. For these purposes, frost-resistant acrylic, created relatively recently with the help of new technologies, is suitable.

Most of these acrylics remain flexible at temperatures as low as -20 degrees Celsius. It is important, however, to protect the acrylic from moisture for at least 5-8 hours after filling the gaps. This will allow it to harden well and maintain frost resistance. After hardening, it can be safely painted or covered with plaster. However, it is worth considering whether it is better to use outdoor silicone, which is more resistant to moisture and mold. Poor quality acrylics can crack quickly due to large temperature fluctuations and prolonged exposure. high humidity.

Universal silicone sealant can be used for:

  • ceramic tile grouts,
  • grouting in bricks,
  • patching cracks in plaster
  • sealing cracks in concrete, etc.

However, it should not be used to seal metals as it can cause oxidation.

Universal silicone is able to withstand low temperatures and moisture, can be used both inside and outside the building. It is very flexible and is ideal for sealing joints in concrete floors, filling joints in plaster on walls, sealing windows and doors, unless, of course, you plan to paint the joint.

Most general-purpose silicone sealants are resistant to freezing temperatures down to -30 degrees Celsius, which is 10 degrees more than good quality specialized frost-resistant acrylics. If necessary, you can also purchase high temperature silicones. Silicones are resistant to temperatures up to 120 degrees, and specialized ones can withstand temperatures over 300 degrees.

Sanitary silicone sealant is ideal for:

  • shower trays,
  • baths,
  • shells,
  • toilets,
  • countertops,
  • and other bathroom and kitchen equipment.

It does not discolour ceramic sanitary ware and acrylic bathtubs, and at the same time is resistant to moisture and mold. It forms a stable and elastic grout that is resistant to the commonly used household chemicals, unlike many universal silicones which can turn yellow in the bathroom. It does not cause discoloration of plaster, grout tiles and has very good adhesion to smooth surfaces.

If you are choosing a silicone bath sealant, which one is better to figure out based on the offers on the market. In the bathroom, for sealing fillet joints between tiles or porcelain stoneware, you should choose the composition right color, as close as possible to the color of the grout.

In the kitchen, sanitary silicone can be used to seal worktops and install gas and induction cooktops.

In contrast to acrylic, sanitary silicone has good adhesive properties, in which case the sink or shower tray usually does not require additional fixing to the surface.

Silicone sealant for glass and mirrors

For sealing and bonding glass to other building materials it is recommended to use special products. Silicone sealants for glass and mirrors have great adhesion, and also do not change the color of the glass, which, unfortunately, is quite common with cheap universal silicones. They do not cause metal discoloration, of stainless steel, brass or aluminium.

In addition, they are much less sensitive to yellowing, which is a common problem with silicone compounds, which can be more noticeable in the case of mirrors or other glass elements.

Silicone glass sealants are resistant to high and low temperatures, freezing, and can also be used outdoors.

From right choice appropriate building chemistry depends on its service life, strength, tightness of the seams and the final result of our work. Therefore, you should carefully choose the option for each room and purpose, taking into account humidity, temperature regime, the need for staining and other factors.

Acrylic sealant is a polymeric non-toxic material designed for processing various holes, joints and slots when performing construction and repair work. The insulating substance is available in the form of viscous, flowing or pasty bases.

Composition

Acrylic sealants are made on the basis of acrylate or acrylic acids. The presence of these substances contributes to the effective sealing and connection of fixed or inactive structures.

Auxiliary components of acrylic sealants are:

  • acrylic emulsion;
  • calcium carbonate;
  • titanium dioxide;
  • plasticizers;
  • various chemical additives.

Advantages

Acrylic sealant for outdoor use has the following set of advantages:

  • the ability to maintain high elasticity after pouring;
  • the possibility of surface treatment with paints and varnishes;
  • resistance to direct sunlight;
  • low content of organic solvents;
  • good adhesion in contact with wet substrates;
  • resistance to high and low temperatures.

Differences between acrylic and silicone sealants

Although acrylic wood sealant is in high demand, silicone-based special crack and joint sealants are also considered a popular product.

If we talk about the difference between acrylic sealant that is decisive for the consumer, then the budget cost comes first, as well as the possibility of coloring. Despite the fact that silicone has increased moisture resistance, acrylic compounds contain a significant proportion of antibacterial and antifungal elements. Thanks to the presence of such components, any moisture and dampness become not afraid of the sealed seams.

Acrylic sealant is easily updated by applying the next layer, which is practically not possible with the use of silicone compounds. Not in the last place in this case is the aesthetic component. Silicone sealant leaves visible white streaks on itself while acrylic products create an even transparent layer.

Acrylic sealant: application

Treating cracks with acrylic sealants does not require knowledge of any rules. The insulating substance is contained in convenient containers, does not irritate the skin and is odorless. While the composition has not hardened, it is possible to thoroughly clean hands and tools.

And silicone compounds are removed only with the use of special solvents. Removing the old hardened layer of silicone paste can become a real problem. To do this, you must first remove the silicone composition mechanically, and then long time wash off residues with specialized washes.

How is acrylic sealant used? The application of the substance occurs in several stages. A surface film forms immediately after application. Depending on the humidity and temperature indicators of the environment, acrylic sealant can harden from one to two hours. This time is completely sufficient to adjust and change the shape of the seam. Further, within a few days, complete polymerization of the substance occurs.

Precautionary measures

Acrylic sealant white is ideal for a wide variety of exterior and internal works. However, its use requires careful attitude. With significant sudden changes in temperature, as well as the impact on the substance of heavy precipitation, some deformation of the material is possible.

It is absolutely not recommended to use white acrylic sealant in expansion joints, which can lead to surface flaking. If, if you need to perform complex outdoor work, there is no other available alternative, then it is better to use an acrylate sealant. This substance has excellent adhesion, as well as increased resistance to weathering.

Specifications

There are a number of recommended settings that are required for efficient processing seams with acrylic sealants. So, the width of the applied seam should be no more than 6 mm. Otherwise, it may be necessary to apply a special sealing cord to hold the layer.

The consumption of acrylic sealant is as follows: a standard container with a volume of 22 kg is enough to process more than 300 linear meters of area. At the same time, the recommended temperature for applying the substance varies from 4 to 32 ° C.

It is allowed to paint the surface of joints sealed with acrylic sealants using latex paints after several days after application. In this case, the surface of the sealant seizes for about an hour.

Acrylic sealants do not tolerate an abundance of moisture quite well. Therefore, it is recommended to work with them in dry weather. If the substance has to be used in conditions of high humidity or during precipitation, in this case the outer layer of the sealant should be temporarily covered with a layer of polyethylene.

As for the packaging of acrylic sealants, they are available in the form of tubes, plastic buckets, cartridges or tubes. The choice of one or another package depends on the operating conditions.

With regard to the duration of storage, the period of use after unpacking the sealant is about a year under normal conditions. At the same time, acrylic sealants fully retain their basic properties if the ambient temperature does not exceed 20 ° C.

A necessary and indispensable material in the repair of any structures, including wooden ones, is a sealant. But how to choose the best acrylic sealant and what material properties to focus on when choosing?

Purpose of sealants and what to consider when choosing

The main purpose of the material:

  • sealing seams and crevices wooden floors, walls, etc.;
  • end protection wooden structures;
  • processing of joints of any parts;
  • filling cracks;
  • other repair work.

The building materials market is full of all kinds of sealants for various purposes. Sometimes such an abundance of compositions leads to a stupor, because the buyer does not always know which option to choose.

  • intended place of use and type of surface. They produce compositions for external and internal work, universal application, for windows, roofs, etc.;
  • environmental features and factors affecting the structure treated with acrylic grease. From general group emit heat-resistant, fire-resistant, sanitary and compositions, the list of which is only replenished;
  • sealant composition.

Acrylic VS Silicone: Key Differences

Many people ask: "Is acrylic sealant better than silicone sealant and what is the reason for this factor?" Naturally, there were some differences, but they are as follows:

  1. Limited scope of silicone sealant. This is about budget options silicone acid lubricants, which sometimes react with the treated surface: metal, cement-containing surface, natural stone(marble, granite). Therefore, the choice of composition must be approached more carefully. Builders recommend, giving preference to this option, use it only on plastic, ceramic or wooden surfaces. While acrylic-based gels are devoid of such a disadvantage. They are boldly called universal, since, regardless of the material being processed, they do not harm the structure.
  2. Aesthetically, acrylic sealants are better. On top of them, you can apply any paint that will lie flawlessly and will adhere well to the surface. Another plus is that the acrylic-based composition does not become cloudy over time and does not turn yellow, compared to silicone.
  3. Possibility of use in rooms with a high level of moisture. Choosing which sealant for acrylic baths fit best of all, the owners are faced with a difficult task: which of the compositions to give preference to? According to customer reviews, it is not difficult to understand that most choose silicone compounds, which are famous for their moisture resistance. Not sure which sealant for acrylic bath pick up? Here it is worth considering the fact that silicone, under the influence of moisture, including sanitary, after some time changes color from transparent to yellowish with a cloudy tint, and sometimes even becomes moldy. The components contained in the acrylic lubricant prevent the development of fungus, which makes it undoubtedly better for use in conditions of high humidity.

Expert opinion and customer reviews about sealants

For the entire period of evolution, it is difficult to remember the number of names and types of materials that were presented on the market. Some of them have long gone from store shelves, while others have been holding leading positions in sales for decades.

When choosing a sealant for wood, as buyers write, first of all pay attention to the price-quality ratio, which is determined by the brand. The loud name of the company, supported by the reputation, speaks of quality. That is why buyers prefer reliable manufacturers, as can be seen from the reviews studied on the Web.

Many refuse the classic and familiar option for everyone - silicone sealant, speaking of the acrylic composition as one of the best. A wide range of products makes the product advantageous for purchase, because the client has the opportunity to choose a sealant for any type of surface, which is beneficial.

According to experts, acrylic compounds, due to their merits, are slowly replacing silicone ones, as can be seen from the recommendations of customers who have already tried using such a lubricant.

In general, reviews of acrylic sealants are positive, and buyers note good adhesion to the surface, the quality and price of the product, making it an advantage in choice.

What kind of sealant for wood?

Depending on the component composition, there are four groups of sealants used for working with wood:

  • acrylic;
  • silicone;
  • bituminous;
  • polyurethane.

Features of acrylic-based wood sealant

This type of sealant is often used for interior work with wood - it is the preferred choice. Unlike other compositions, it lends itself well to staining with acrylic-containing paints or varnish, which is important when interior decoration and room design.

The tool is moisture resistant and not waterproof. The first option is more popular, as it is more actively used in repairs and is not afraid of negatively affecting factors. In addition, waterproof lubricants bond porous surfaces well. Compared to a waterproof sealant, the second one is much more capricious and is not suitable for all types of work. When working with this type of material, it is worth paying attention to some distinctive characteristics. Non-moisture resistant acrylic sealant does not tolerate moisture, and if even a small amount of water enters, the formed seam begins to disintegrate. In addition, it is susceptible to low temperatures. Despite this, even such a material is characterized by some advantages, including complete safety for the human body and no smell. Among the shortcomings, the property of reduced elasticity is distinguished.

The main purpose of acrylic sealant for wooden surfaces- filling of cracks and seams, which in the future, without timely processing, will succumb to deformation loads.

How to choose a lubricant for the joints of concrete structures?

Insulation of the roof and facade elements is not complete without a special sealant on an organosilicon or polysulfide liquid viscous rubber base. Such lubricants are characterized by resistance to temperature extremes in a wide range - -55 ... + 80 ˚С. Familiarize yourself with the features of the compositions for seams when performing outdoor work.

Species diversity of mixtures

Sealants are classified by type, based on the type of base, which happens:

  • bituminous;
  • polyurethane;
  • acrylic;
  • silicone.

Since the topic of the article is devoted to acrylic sealants, we will dwell on this type of lubricant in more detail, specifying information about sealants for joints in concrete.

With the help of such a composition, it is easy to get rid of cracks in concrete, smooth out joints in the floor, windows, walls. The only drawback of acrylic joint sealant is its low elasticity, which makes the material unsuitable for interior work.

From positive qualities composition notes:

  • easy connection with porous surfaces, provided by increased adhesion of the sealant;
  • absence bad smell;
  • component composition that does not include any kind of solvents;
  • an extensive range and the ability to choose a pigmented sealant that does not differ in color from the surface being treated;
  • the possibility of painting, varnishing after the complete curing of the lubricant.

Of the features of the material, the need to apply to an exceptionally dry surface and the difficulty of working with a sealant at low temperatures are mentioned.

Having studied the features of the types of sealants described above and familiarized with the details of the use of the material, it remains only to say that the choice is only up to the buyer, but positive reviews, unique characteristics and availability of the material make it the preferred choice for any construction work.
