  • Strengthening the protective properties of the treated surface: water resistance, heat and cold resistance, resistance to mechanical stress and vibration, respectively;
  • providing the necessary performance properties to the base layer, as an example, plasticity, to prevent cracking.
  • Improving the caliber of the working surface following the prior rougher treatment and preparing it for further finishing;
  • Offering the surface a decorative look, uniform coloration.

  • After sealing the joints of KNAUF-sheets using a thin border of the AC ~ 0.30-0.35 kg/m2
  • at full puttying of the surface with 1 mm layer thickness ~ 1.7 kg/m2

Procedure of functions

The warmth of the base along with the space air must be 10°C.

KNAUF-boards must be firmly constructed on the load-bearing framework, be sterile, clean and dust-free. Puttying the joints of KNAUF-boards need to be created at the operational temperatures and humidity requirements, after all work associated with its modifications, which instills linear deformations of gypsum board sheets.

Plaster and concrete foundations must be dry, cleaned of dust, dirt and delamination. Massive irregularities or damages have to be levelled with KNAUF-Fugenfüller compound and dried.
