Work of the caulker
The first mission of the caulking specialist is to prepare the surfaces before applying the silicone in order to obtain a good adhesion and a good seal in a durable way.
1- Cleaning the surface
2- Applying a primer
3- Application of sealant for perfect caulking joints
For a good adhesion, the sealant is installed after the application of the primer. The seal is placed straight and continuously with a suitable pistol, avoiding bubbles or asperities and weaving the seal with a spatula.

Role of sealants in caulking
The main role of sealants is to fill a gap to prevent water, air, dust or insects from entering. These seals are also used as a protective layer on a surface that provides
- sound insulation (noise-cancelling) and
- thermal insulation (heat preservation).
The sealing process simply forms a protective barrier against the external elements.
