When carrying out repair and construction work, acrylic sealants are actively used. The main advantage of these compounds is affordable cost, easy application and good technical characteristics. This is one of the most demanded materials for work on concrete and wood, sealing joints between logs and ceramic tiles.
Hermetics on an acrylic base expelled from the arsenal of builders gypsum and alabaster, as well as putty and putty. Due to the low price and its properties can compete with silicone based sealants. There are material shortcomings, considering that you can avoid serious problems. The main purpose of all brands of acrylic sealants - the filling of voids in motionless and inactive designs.
The main advantages of acrylic sealants
Creates sealants based on acrylates, which affects the technical and decorative characteristics. As a solvent, after evaporation of which the composition acquires its practical properties, water is used. The classic acrylic white sealant has the following important advantages:
- stability of seal dimensions after application;
- long-term preservation of its properties - no less than 10-15 years;
- the hardened sealant tolerates vibration well;
- retains its color throughout its life;
- antifungal components protect against the formation of fungi and mold;
- environmentally friendly composition that does not have unpleasant odors;
- high level of fire safety;
- it is stained with acrylic or oil paints;
- affordable cost.
Manufacturers produce frost-resistant sealants, moisture-proof compounds that can be used in bathrooms and other rooms with high humidity.
Various brands of acrylic sealants are used, the classification of which can be based both on application and color. By its shade, the compositions are white, transparent and colored. After applying acrylic sealant, it practically does not change its shade. If the transparent silicone becomes cloudy, then acrylic does not lose its light transmitting ability. This property can be used when working with glass surfaces, decorating furniture.
An important advantage of acrylic sealants is the ability to stain. Silicone seams have low water absorption, paint does not lie on them, and the white surface does not remain long, acquiring a characteristic yellow tinge. For this reason, in the course of finishing work, builders prefer to use acrylic sealants to seal seams.
Disadvantages of acrylic sealants
One of the main disadvantages of universal acrylic sealants is low water resistance. It is for this reason that it is recommended to use a specialized acrylic sealant for the bathroom when working in this room. Universal compounds, developed on the basis of an aqueous dispersion, therefore under the influence of high humidity they are destroyed. Acrylic sealants are not suitable for systems with high loads. Regular squeezing or stretching will lead to the destruction of the joints.
A complex relationship between acrylic sealants and temperature regimes. Manufacturers produce frost-resistant compounds used for outdoor works. The maximum temperature at which acrylates retain their characteristics reaches + 80 ° C. By this indicator, they are inferior to silicone compounds, but are quite suitable for operation in all climatic zones. On the other hand, the frost-resistant and heat-resistant properties of universal acrylic sealants can become irrelevant in a situation where the surface temperature on which they are applied will experience temperature fluctuations of 10%. In such conditions, sealant for joints crack, begins to pour, losing its practical and decorative properties.
The loss of elasticity and technical characteristics occurs also with the use of universal brands in the cold. They try to use them to reduce the cost of repair work, but it is better to use frost-resistant compounds. Only in this case it is possible to seal seams, joints without loss of elasticity irrespective of operating conditions.
Main technical parameters
The scope of use of any building material is determined by its basic technical parameters. Acrylic sealant has the following characteristics:
- recommended width of the seam - no more than 5 cm;
- recommended joint thickness - 50% of the width;
- flow rate - a standard tube with a volume of 325 ml is calculated for 5 running meters of joints with a width of 10 mm and a thickness of 6 mm;
- recommended application surface temperature - from +5 to + 32 ° C;
- operating temperature range - from -40 to +80 ° C;
- staining - 21-30 days after application;
- time of full hardening - 21-30 days at humidity of air of 50-60%;
- setting with the surface - up to 60 min;
- frost resistance - up to 5 cycles.
When planning the work, it is necessary to take into account all technical parameters, only in this case it will be possible to guarantee the high quality of the work performed.
Areas of application of acrylic sealants
Sealing operations can be made with waterproof and non-waterproof compositions on an acrylic basis. Experts recommend that they be used for internal work. For outdoor use, only frost-resistant compounds are suitable, which can be operated indoors.
The non-resistant single-component sealant, due to its properties, can only be used in dry rooms with normal humidity. It is used for the installation of wooden, plastic plinth, foam pliers. Used sealant for tiles from expanded polystyrene, when working with plasterboard.
With the help of acrylic, it is possible to install decorative elements on walls of concrete or brick, seal seams between tiles or clinker. The sealant provides a quality connection of wood components, thanks to good adhesion to this base. It is actively used in the repair of furniture at home.
Waterproof sealant on acrylic base is used much wider, it has excellent adhesion to the following reasons:
- wood and plywood;
- tiles and ceramic bricks;
- aerated concrete and foam concrete;
- concrete plates.
Sealant is applied on rough, porous and smooth surfaces. You can use it in the kitchen and in the bathroom, where the humidity is higher than in the other rooms. This is a good sealant for windows, used to seal joints in wooden frames.
Acrylic sealants are used to seal seams in a laminate and the floorboard, the manufacturer produces a wide range of products with a shade that is close in color to different types of wood. Due to this and good adhesion to wood, such compounds are widely used for sealing joints between logs. From environmentally friendly material today, build homes, cottages, baths, motels and holiday homes. In this case, traditional technologies are not always used to seal seams, which are formed between logs. Previously, hemp was used for log cabins, but the durability and quality of such a sealing do not always suit potential customers.
Used acrylic sealant for wood is close in color to the wood used. It is recommended to use a sealant for outdoor work that can withstand high humidity and condensation. Internal and external seams are sealed, this helps to prevent the appearance of drafts, dampness, insects in the house. Also, the joints between the wooden logs and the concrete of the foundation are subjected to treatment, since acrylic has an excellent adhesion to these substrates.
Acrylic sealant is the ideal material for the frame, with its help perform the finish trim. Also, compositions with a shade under the wood are used for the repair of houses from profiled and glued beams or cottages with a block-house finish, lining, imitation of the beam. It is used to seal the holes formed when knots fall out, as well as other flaws in the surface of the wood. In the process of exploitation, the tree is crumbed and crevices are formed between the walls of the lining or the blockhouse, which can also be removed with acrylic based sealant.
Used sealant for fixing ceramic and tile to surfaces, including in log buildings. This material is more simple to use than specialized adhesive compositions. When laying the tiles there is enough time for adjustment, which allows to ensure high quality of work. The same composition can be used for jointing, waterproof sealant reliably protects the inner surface of the tile from increased humidity. The most popular white sealant is a universal shade, which is suitable for a variety of tinted collections of tiles.
The sealant for concrete is used in the repair of window sills made of this material. With its help, the cracks and seams between the slab and the wall are closed. Sealing the connection between the window sill and the wall will ensure the absence of drafts in the house and prevent the formation of dampness.
Manufacturers produce special sealants for windows, they can be applied on the surface of concrete and wood. Accordingly, the scope of such material is expanded, for example, with this acrylic, crevices in logs, as well as between the wall and the floor can be sealed. The compositions developed for the laminate flooring, a popular floor covering, are no less effective when working with wall boards, blockhouse, imitation lumber, plywood and MDF.
When choosing a sealant, you need to pay attention not only to the water resistance of the composition, but also to its elasticity. If the sealed surfaces can be subject to vibration, then it is better to apply a frost-resistant composition. Its elasticity is much higher due to special additives that do not allow the composition to break down under the influence of low temperatures.
Acrylic compositions some experts recommend for roofing works. At the same time, low resistance to water flows, temperature changes and high temperature is completely forgotten. Roofing material in the sun can heat up to 80-90 degrees, which is critical for acrylic. Use acrylic sealant can only be done with the installation of wooden roof windows, sealing the connections between the frame and the truss system. For other types of roofing work, different brands of waterproof silicone sealants are more suitable.
How to choose the right acrylic sealant
The sealant has good adhesion to most materials, but plastics are an exception to this rule. Ensure good adhesion to them can only specialized compounds. If these are not available, then it is necessary to use a primer as an additional layer between the plastic and the acrylic sealant.
Moisture-resistant compounds used in the bathroom, in the kitchen or on the balcony, should contain fungicidal additives. In this case, mold and fungi will not form in the filled joints, which can destroy the compaction. To seal the aquariums it is recommended to use specialized sealants. They have increased resistance to aggressive environments, while absolutely safe for living organisms.
Sealants are often used to seal the masonry of fireplaces, stoves and pipes. For these purposes, only specialized formulations capable of withstanding high temperatures should be used. Acrylic sealants are not suitable for this purpose, as the limit of their heat resistance does not exceed + 120 ° C.
Features of the use of acrylic sealants
How to apply one-component acrylic based sealants? This is one of the most easy to use materials, the method of application depends on the form of delivery. Sealants are packed in tubes or plastic buckets. Tubes are the best option for applying in narrow seams formed by ceramic tiles. Plastic buckets are relevant for large volumes of work, for example, sealing joints between logs log.
To work with acrylic based sealants, professional skills are not needed. It is enough to have the desire to perform a job qualitatively, and simple hand tools should be at hand. Regardless of the form of packaging and the type of single-component sealant used, qualitative preparation of the surface is required. In the seams there should be no dust, residues of building materials. All surfaces that will come in contact with the sealant must be clean and degreased. Only in this case the necessary adhesion and preservation of the properties of the applied acrylic will be ensured.
If sealant is used in tubes, an assembly pistol is required for operation. It is easy to operate and affordable. The tube is inserted into the gun, the "nose" is cut off and the dispenser is installed. Using a piston, the mixture is uniformly squeezed out. It should be applied at an angle of 45 degrees to the sealed joint, this will ensure maximum adhesion to the surface.
When using a sealant, packed in plastic buckets, a rubber spatula is used for the application. This hand tool is practical and convenient to use, it is used for compaction and for removing surpluses. Correction of the seam is carried out until the sealant is frozen. A thin layer of dried sealant can be removed with a damp cloth.
When using waterproof or conventional acrylic sealant on objects with a large amount of work there is a desire to save. Reduce the consumption can be with a special sealing cord, which fits into the seam. This is relevant for the deep cracks between the sills and frame, plinth and wall, when layi
ng large-format tiles. Using this material will help reduce the consumption of sealant by 70-80% and accelerate the process of filling voids.
One of the main advantages of sealants of this type is the possibility of their further staining. To do this, the dried layer of waterproof sealant must be treated with sandpaper, remove dust and debris, after which you can apply acrylic or oil paint.
Sealants of white or any other color based on acrylate are environmentally friendly compounds. As a solvent, water is used, so when it comes to hand, the sealant is easily washed off with water.
Leading manufacturers of acrylic sealants
All the positive properties of compositions based on acrylates are characteristic only for quality products. The availability of acrylic acid derivatives and their low price lead to the fact that acrylic sealants are often falsified. For this reason it is necessary to use the products of well-known manufacturers, in our market, sealants from Poland, Germany and Russia deserve the greatest attention. Among the most famous manufacturers:
- Novbytkhim is a Russian company that produces acrylic sealants in compact tubes;
- Zigger is a German manufacturer of one-component compositions for repairing parquet and laminate, as well as tubes with white sealant for sealing seams and cracks;
- Henkel is a German company offering quality frost-resistant sealants in various containers;
- Belinka is a company from Slovenia, producing elastic sealants for parquet and civil works;
- Loctite - Russian frost-resistant sealant for sealing seams of inactive structures;
- Penosil - compounds with high adhesion, can be used for working with plastics, manufactured at Russian enterprises of the international concern;
- Tytan are practical sealants from Poland, distinguished by an excellent balance between price and quality.
It is not recommended to use cheap acrylic sealants of unknown brands, to reduce the cost can only be due to the use of poor quality raw materials and a large number of fillers. Such compositions have weak technical characteristics, are characterized by low viscosity and poor adhesion, are characterized by a short service life.
