Liquid glass for waterproofing

 Liquid glass for waterproofing

The modern market offers a huge range of waterproofing, differing in terms of use, cost and other characteristics. This product is actively used both in everyday life and during large-scale finishing and construction works. The scope of this composition will be discussed in the article.

General information

Liquid glass is a special solution based on water with the addition of potassium and sodium silicates. The composition has a viscous and at the same time dense structure, due to which the product is ideally suited for waterproofing works.

When considering the structure of the material, you can see small crystals.These elements tend to increase after application to the surface. Components fill in small cracks. Thanks to this function, liquid glass has an air-tight and water-repellent property.

How does the product work?

The principle of the special composition has an adhesive ability. Special solution molecules penetrate deep into the porous substance, creating a dense and wear-resistant film. Due to this function, adhesion is formed. According to visual signs, the composition of the glass is similar to rubber, only in the state of liquid. In the manufacture of the product, in addition to the main components, manufacturers use quartz sand and soda.

In the manufacturing process, liquid glass goes through several stages:

  • splitting up;
  • burning;
  • re-crushing, in which the material is converted into powder.
