Concrete Smooth – how to do?

Concrete Smooth may be required when making stairs or flat floors. As a rule, such a coating can be found in parking lots or in industrial workshops: the concrete surface is shiny and very smooth to the touch. In this case, the effect is achieved by using special technology with the addition of “topping”. The manufacturing process for such a coating requires expensive floor polishing techniques. Also sometimes there is a smooth-looking concrete wall or the surface of a staircase in a private house. This is an example of high-quality applied microcement – a two-component mineral composition for the manufacture of a finishing coat.

Concrete Smooth – make floors

Raw concrete floors themselves have two main disadvantages. Firstly, during active use, the coating gives a large amount of dust generated during the erasing of small particles of sand and cement from the upper layer of the concrete slab. Secondly, the material itself has great porosity, which leads to the unimpeded absorption of any liquid that enters such a floor.

Obviously, in residential premises, both of these drawbacks preclude the use of untreated concrete as a topcoat. For this reason, in most cases, in private houses and apartments, concrete screed is used as a rough floor, on which one of the most popular finishing coatings is installed, such as laminate, parquet, linoleum or others.

However, if a system of underfloor heating is laid in a concrete slab, it will work much more efficiently if the concrete is not covered with a finish coating. An additional finishing layer on top of the plate will create a heat-insulating barrier that prevents the passage of thermal radiation. This not only increases the energy consumption for space heating, but also reduces the level of comfort from the thermal sensations obtained by contact with the floor surface.

There are two technologies that allow you to get Concrete Smooth without having to apply a layer of plastic. The first is a modification of the top layer of the concrete screed using liquid glass (potassium or sodium silicate) or sodium or magnesium fluorosilicate. The use of fluorosilicates can achieve the greatest smoothness and even a mirror effect on the surface of concrete.

The essence of the method is that, when in contact with concrete, these compositions form a new hardened layer, which is several times more wear-resistant than a simple concrete coating. Due to its increased strength, such a surface does not form dust and is completely waterproof. In addition, due to the lack of plastic, such a coating can be considered absolutely environmentally friendly and completely acceptable for use at home.

The only significant drawback is the cost. The coating manufacturing process involves applying a protective composition in several layers. In addition, after the last layer has dried, the floor is ground by a special machine with disks having diamond spraying on work surfaces. To obtain such a degree of smoothness, as in the photo above, you will need a technique with discs that rotate at a speed of at least 1000 rpm.
