Brick varnishes: varieties and application features

Brick varnish, necessary for both external and internal work, is used to create a protective surface layer and give a more attractive appearance. It is able to increase the service life by many years and protect the base from external influences, be it atmospheric phenomena or chemicals.

The modern market offers a huge assortment of similar products, varying in quality and price. In this article, we will look at the advantages of brick varnish, its characteristics, types, and also give a small overview of the most popular products.

By its properties, brick varnish is a versatile tool that is suitable for both external and internal work. It fits perfectly on both vertical and horizontal bases, while not rolling or deforming. The product has a huge number of advantages, thanks to which it is in high demand.

As you know, brick begins to gradually lose its strength from constant interaction with moisture. Most of all, the external walls of buildings are subject to destruction, which take on precipitation and dust throughout the year. That is why it is important to qualitatively protect the facade by treating it with varnish, which will not only give it water-repellent properties, but also prevent deformation of the supporting structural elements.

Another plus is the protection of the masonry from high temperature values, which is especially important for brick fireplaces. In addition to giving the exterior gloss, the structure will be protected from fire for many years to come.

It is also an excellent remedy for preventing white salt stains on exterior walls or brick fences. The composition protects against the appearance of fungus or mold, increases the level of protection against exposure to ultraviolet rays, which are known to be most harmful. Accordingly, you can be sure that the color of the masonry will not fade in the sun.

The wall or floor will look in a more advantageous light when coated with brick varnish: the product gives the surface a smooth and shiny look. Due to the special properties of the composition, dust accumulation is also prevented. When walls are covered with varnish with a high gloss percentage, the effect of a wet surface is achieved. Such products, as a rule, are used more often for country brick houses or for interior decoration at the request of the owners.

Varnishes vary in gloss levels. The choice depends entirely on your taste preferences. You can cover the walls of the house with a glossy or matte finish. There are also semi-gloss and semi-gloss varieties.

Another classification implies separation by internal composition. Despite the versatility of brick varnishes, each substrate has a specific product. In total, there are three most common types: polyurethane, polymer and silicone-acrylic. Each of them has its own set of characteristics.

They are among the most popular, since in order to protect against corrosion and other types of damage, they can be applied not only to brick substrates. Due to the versatility of the composition, it is perfect for covering walls even at sub-zero temperatures. A big advantage of polymer products is the speed of drying, which significantly reduces the duration of work.The mixture is resistant to any temperature extremes and changes in the level of humidity, it can be used not only for external, but also internal work in rooms without constant heating.

Another plus is the ease of applying the composition: it can be used by both professional craftsmen and beginners in repair. The polymer product increases the wear resistance of any surface, as it is resistant to abrasion, protects against damage and scratches. Gives a shiny appearance.

These paints and varnishes have a fairly affordable price, so they will be affordable for many.

Such products are more often used for indoor work. They can cover not only brick bases, but also ceramic tiles, concrete, drywall or metal. The product prevents the appearance of a yellow tint on the walls. Often, silicone-acrylic compounds are also used to cover decorative surfaces.

This type of mixtures can be colored due to special polymers in the composition, so in addition to gloss and protective film, the wall can get any color of your choice. Thanks to this paint and varnish coating, the surfaces of the house will be resistant to alkaline compounds, acetone, oils and other chemicals. However, such varnishes have a high price, so their use is recommended more on internal coatings than on external facades.

In contrast to their polymer analogs, mixtures are not consumed so economically. This is another reason why silicone acrylic products are recommended for indoor applications that are guaranteed to be protected from external influences.

These products are also versatile in their properties and can be used for both external and internal purposes. After application, the mixture forms a thin transparent film on top of the base, which serves as protection against negative weather conditions. Polyurethane varnishes can also be colored if you add a special dye to them. It is such a paint and varnish that creates a wet effect on a brick surface, thereby giving it an even greater shine.

The composition is recommended to be used more for external work.as it has excellent protective characteristics and can be used on concrete substrates. The increased moisture-resistant properties of polyurethane mixtures provide wall protection from water.

In addition to the three main ones, one more type of varnish for bricks is distinguished - this is a special mixture for stoves. Its composition has increased heat resistance and protects the masonry from constant contact with fire.

One of the manufacturers of the highest quality brick varnishes is German company Pufas... A huge number of construction products are produced under the brand name, but the brick lacquer of this concern has the largest number of positive reviews.

American firm Petri has been supplying its products all over the world for many years. One of the most popular products is a wet effect stone paint that protects the surface from dirt and rapid wear.

Among domestic manufacturers, one of the leaders is Neomid brand, which supplies the market with a semi-matt varnish "Neomid STONE". Due to the complete absence of a toxic odor, this composition can also be used indoors.

"Chief Technologist" manufactures high-quality products from imported raw materials, which will be an excellent assistant for completing repairs. Heat-resistant varnishes for bricks will protect surfaces from any negative influences.

The scope of application of such varnishes is much wider than it seems at first glance. In addition to brick walls, heat-resistant coatings will also provide excellent protection for substrates made of other materials. It is possible to apply paint and varnish compositions on concrete and mineral surfaces, on gypsum and ceramic tiles, natural stone, slate.After drying, a protective film forms, giving the base a shine, emphasizing its texture and naturalness. By the way, it is recommended to varnish not only the brick itself, but also the seams between them.

The modern construction market offers a wide range of varnishes for brick and stone. There are goods at both high and low prices. Many people will like aerosols, which will greatly facilitate repair work.

It is important not only to use the composition correctly, but also to correctly select it in advance:

• When buying a varnish for external work, pay attention to the level of its moisture resistance, it should be as high as possible in order to provide high protection against water and ultraviolet radiation.
• It is necessary to apply the mixture in two or three layers, first letting each previous coating harden. This approach will prevent drips.

• To give the surface a more interesting look, many designers recommend painting the inter-brick seams in a different color, which will provide, in addition to a beautiful appearance, a greater level of protection for the base.
• For concrete surfaces, it is recommended to use a polyurethane compound, as it will provide maximum protection against moisture. Varnishes can also be applied to foundations or bearing surfaces.
• Polyurethane mixtures have an affordable price and economical consumption, which is why they are most often used for outdoor work.
• For interior decoration, it is recommended to use silicone-acrylic mixtures, since they do not have a toxic odor and give an enhanced shine to the surface.
