How to choose a stone and concrete varnish for outdoor use (frost-resistant)
Concrete is pretty tough, wear-resistant and durable material that is not afraid of temperature changes and aggressive chemicals. Now, different types of structures are made from concrete, including foundations, buildings, floors, walls and interfloor ceilings.
Although the material itself is very durable, its surface needs reliable protection, which the concrete varnish composition can provide, which significantly increases its service life. So, let's talk about stone and concrete varnish. Each type of concrete varnish has some characteristics.
They produce paint and varnish materials that have increased wear resistance, high temperature resistance and excellent moisture resistance or fire resistance.
But each varnish composition for stone and concrete has such characteristics, properties and Features:
Despite the fact that stone and concrete are strong materials, they are under conditions of increased mechanical impact or outdoors, under the influence of aggressive natural conditions, precipitation and temperature changes, and also the surface of such materials can begin to exfoliate, crumble and turn into dust.
The base can be significantly strengthened by lacquer compounds used for brick, stone and concrete.
Protective varnishes are applied after perfect drying of concrete, the varnish composition will strengthen concrete surfaces, and also increase the technical properties and service life of such a material.
Manufacturing companies make a varnish composition for concrete for interior work, and for application in the open air. Varnish compositions are usually used to cover the following objects:
Please note that they use a lacquer composition for concrete to strengthen the material, make it resistant to abrasion, and also to make the stone more beautiful.
In shops you can purchase various varnish compositions for concrete for outdoor use and interior decoration. For each type of varnish composition, different bases are used, depending on this, they can be:
They have the maximum indicators of resistance to moisture, and therefore are mainly used in places where the air humidity is constantly increased. Most often, polyurethane varnish for concrete is used for outdoor work, where it will be applied to paths, sidewalks, and also to protect saunas and swimming pools.
Silicone solutions were able to combine excellent decorative properties, as well as high resistance to moisture.
Moreover, varnish solutions should be divided according to composition, and varnishes can be divided according to the type of gloss, and there are the following varieties:
By the way, the last two are applied to create an attractive finish, they will create the effect of a wet stone. But the first two concrete solutions are used in those rooms where there is increased traffic, and the varnish layer will experience daily increased mechanical loads.
This applies to industrial premises, public places such as airports, train stations and the rest. On the matte surface, scratches and other defects are not very noticeable.
Despite the very high cost, such materials are the most popular.They quickly and easily penetrate the concrete base, strengthen the materials, fill all cracks, and this greatly increases the strength of the screed. You can also use a polyurethane mixture together with the same impregnation composition, due to which the effectiveness of the layer will greatly increase.
Moreover, the impregnation improves the adhesion performance, as well as resistance to moisture and mechanical stress, which will increase the life of the concrete.
One of the most high-quality and popular compositions is the polyurethane varnish composition for concrete Tistrom. The solution from this manufacturer is most often in the garage, in the warehouse, in the workshop and in other places.
The main advantage of Thistrom varnish is its high resistance to the effects of chemical oils, petroleum products and other technological solutions. This varnish mixture can be easily applied, and in addition to excellent protective properties, it also has an external attractiveness and decorative effect.
Thystrome is not afraid of wet cleaning, which does not lose its technical properties. This mixture is also often used to strengthen concrete floors on a farm, livestock farms, in a production organization.
It is these compositions that will enhance the quality of concrete, and after using such a varnish, the coating will receive very excellent performance properties. Polymer agents are much better able to repel moisture than polyurethane varnish for concrete (for outdoor use), and they are ways to effectively resist an aggressive environment, applied both indoors and outdoors. After the composition dries, the base will become strong and durable, and the polymer products dry out quickly enough, and therefore are often used to cover large areas.
Styrene will be the main component of such varnish mixtures, which makes the coating highly durable and resistant to various chemicals. One of the most popular representatives of polymer solutions will be Teksol varnish for concrete surfaces, which can be used as an element of decoration, when processing curbs, bricks, paving stones, stone and the rest. Texol can be easily applied, and after drying is extremely slow to wear off, have high resistance to aggressive atmospheric influences.
Although they are quite expensive, it will compensated by the small consumption of such mixtures when processing one square meter. As a rule, mixtures based on silicone and acrylic are matte.
Such solutions can be applied with existing production. The most rational use of such varnish compositions will be to cover those places that are subject to enormous loads and severe wear.
A layer of such a varnish applied to a stone or brick will not turn yellow even after many years, and the resulting film has a high protection against moisture.Acrylic and silicone compounds are usually odorless and are safe for indoor use. These varnishes can be applied to all types of building materials, including metal and plaster.
By adding special pigments to them, it is possible to give such solutions a special texture and range.
It should be remembered that any varnish for concrete and stone is a synthetic mixture, since there will not be superfluous protective agents, namely respirator, gloves and glasses. If the varnish is applied indoors, then the room must be thoroughly ventilated. Before applying the varnish composition to a concrete surface, bricks or even stones, such building materials should be pre-prepared.
This will include cleaning from dust, dirt, grease, drying and, if necessary, priming.
When applying varnish solutions, the air temperature should not exceed +35 degrees. Almost all types of varnishes can be applied using a roller, brush and pneumatic spray from a spray bottle. If the substance is sprayed, then first it is worth diluting it to the required viscosity level. It is required to varnish at least in two layers, and if the surface of concrete or other building material is very porous, then at least 3-4 layers are required.
So that the varnish solution does not run out during application, when purchasing it, you should correctly calculate the consumption per square meter, and then buy the required amount of funds.
Experts advise covering concrete bases with a polyurethane agent, because they have the highest moisture resistance. And if you need to process internal walls or artificial stone, then it is better to apply acrylic or silicone varnish compositions to them. Polymers cost much less, have a huge range of applications, and can be applied to both interior and exterior surfaces. Before you start using any means, be sure to read the full instructions.
