Concrete is the most popular building material in our time. It is from concrete that both small residential premises and huge industrial facilities are built. And of course, regardless of the type of construction, concrete needs to be strengthened, strengthened, protected, etc. Today, there are many different materials of construction chemicals that are designed to protect against damage and extend the service life of concrete foundations. In this article, we propose to deal with such a coating as concrete varnish.
What are the varnishes for concrete?
Depending on the main constituent material , there are the following types varnishes for concrete:
based on acrylic- water-based
- based on polyurethane
- polymer-based
Each of these types is a high-quality and reliable material, which is selected depending on the operational needs of the surface.
In addition to varnishes for concrete, there are membrane-forming agents, which many manufacturers also refer to as varieties of varnishes or even sell them, the names "varnish for concrete". Although this is not entirely true, the varnish and the membrane-forming agent have a number of differences.
What is the difference between a membrane forming agent (curing) and a concrete varnish?
The membrane forming agent (or curing for concrete, as many masters call it) is the same transparent hardener for the concrete surface as the varnish, but its strength and wear resistance are slightly lower. This material perfectly serves as a concrete base hardener. It provides a longer service life of concrete in comparison with a "bare" concrete screed.
In addition to improving the strength characteristics, increasing wear resistance, insulation and protection of concrete, varnish for concrete creates a beautiful surface that can be both glossy and matte or semi-matte.
An excellent example of curing for concrete is a material based on Teknokur 100 acrylic emulsion. Thanks to it, freshly laid concrete will be protected from moisture loss (rapid moisture loss leads to cracks) and its mechanical strength will be significantly improved.
Apply the material in 2 layers with a break of 6 hours with a spray gun or roller immediately after pouring the concrete mixture. The density of Teknokur 100 is 1.01 kg/l.
What are the advantages of using varnish for concrete?
Practice shows that the application of varnish for concrete significantly increases its service life, because this material:
- Increases the wear resistance of the surface
- Increases the water resistance of the surface
- Prevents the formation of cracks on the surface as a result of freeze-thaw cycles
- Protects the surface from burnout or from other atmospheric influences
- Some species varnishes, for example, Teknocila 300 protect the surface from the influence of chlorides
- Some – give the surface resistance to UV radiation, for example, Teknocila 350
- And some, like Teknocila 400, make the surface resistant to various chemicals and alkalis.
