What is sealant used for?

Concrete is capable of collapsing. This comes from the negative effects of the environment, as well as due to improper mixing of the solution. Sealants prevent cracking, while concrete does not lose its quality.

/

To close cracks in the material, a special mixture is used, based on polyurethane. This tool is used for external work.

What are sealants?

According to the method of exposure, they are divided into two types:

  • Surface - used to form a film on the surface that protects concrete from the negative effects of moisture;
  • Penetrating - these are compounds that protect concrete, passing in depth.

Where is sealant used?

Choosing the right composition depends on the purpose of using the sealant. Before purchasing it is necessary to carefully study the information on the package. There should be information about such qualities as:

  • Resistance to low temperatures;
  • Heat resistance, etc.
/

Among other things, it should be remembered that it is impossible to use sealant, which is intended for internal work, outside the building. Otherwise, the material will collapse very quickly.

/

If the sealant will be used to seal compounds that are located under water, you should choose a composition that is designed for use under pressure. This information is available on the packaging.
