Varnishes for bricks: types and features of application

Brick lacquer, necessary for both external and internal works, is used to create a protective layer of the surface and make it more attractive. It is able to increase the service life for many years and protect the foundation from external influences, be it atmospheric phenomena or chemicals.

The modern market offers a huge range of similar products, different in quality and price. In this article we will look at the benefits of lacquer for bricks, its characteristics, types, as well as a brief overview of the most popular products.

According to its properties, brick lacquer is a universal tool that is suitable for both exterior and interior.It fits perfectly on both vertical and horizontal bases, while it does not roll down and does not deform. The product has a huge number of advantages, thanks to which it is in high demand.

As you know, a brick begins to gradually lose its strength from the constant interaction with moisture. The outer walls of buildings, which take up precipitation and dust throughout the year, are most susceptible to destruction. That is why it is important to qualitatively protect the facade, treating it with varnish, which not only gives it water-repellent properties, but also prevents deformation of the supporting structural elements.

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

This is also an excellent tool to prevent white salt stains on external walls or brick walls. The composition protects against the appearance of fungus or mold, increases the level of protection against exposure to ultraviolet rays, which, as you know, can do the most harm.Accordingly, you can be sure that the color of the masonry will not burn out in the sun.

The wall or floor will look in a better light if they are 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 the walls are coated with varnish with a large percentage of gloss, a wet surface effect is achieved. Such products are usually used more often for suburban brick houses or for interior decoration at the request of the owners.

Lucky vary in gloss level. 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 involves the separation of the internal composition. Despite the universality of lacquers for bricks, each base corresponds to 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 one of the most popular, as in order to protect against corrosion and other types of damage, they can be applied not only on brick bases. Due to the versatility of the composition, it is perfect for covering walls even at sub-zero temperatures. A great advantage of polymer products is drying speed, which significantly reduces the duration of work. The mixture is resistant to any temperature changes and changes in the humidity level, it can be used not only for exterior but also for interior work in rooms without constant heating.

Another advantage is the ease of applying the composition: It can be used by both professional masters and beginners in repairs. The polymer product increases the wear resistance of any surface, as it is resistant to abrasion, protects against damage and scratches. Gives a brilliant look.

These paints have a fairly affordable price, so many will be affordable.

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

This type of mixture can be colored due to the special polymers in the compositiontherefore, in addition to the gloss and protective film, the wall can receive any color of your choice. Thanks to this lacquer coating, the surface of the house will be resistant to alkaline compounds, acetone, oils and other chemical means. However, these varnishes have a high price, so their use is recommended more on the internal surfaces, rather than external facades.

Unlike their polymer analogs, mixtures are not consumed so economically. This is another reason why silicone-acrylic products are recommended to be applied in rooms that are guaranteed to be protected from external influences.

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

The composition is recommended to use more for external work., as it has excellent protective characteristics and can be used on concrete foundations. Increased moisture-resistant properties of polyurethane mixtures protect walls from water.

In addition to the three main, there is another type of varnish for bricks - a special mixture for furnaces. Its composition has high heat resistance and protects the masonry from constant contact with fire.

One of the manufacturers of the highest quality brick lacquers 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 most positive reviews.

American company Petri For many years, supplies its products worldwide.One of the most popular products is a wet effect lacquer coating to protect the surface from dirt and rapid wear.

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

"Chief Technologist" produces high-quality products from imported raw materials, which will be a great assistant to complete the repair. Heat-resistant brick lacquers will protect the surface from any negative effects.

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 be an excellent protection for the bases of other materials. It is possible to apply paint and varnish compositions both on concrete and mineral surfaces, on gypsum and ceramic tiles, natural stone, slate. After drying, a protective film is formed, giving the base 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 brick and stone lacquers. There are goods both at high and at low prices. Many will appreciate the aerosols, which greatly facilitate repair work.

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

• When buying a varnish for external works, 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 UV light.
• It is necessary to apply mixes on two or three layers, previously giving to each previous covering to stiffen. This approach will prevent drips.

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