To avoid the water loss of Silicon A4 and get better adherence to the wall, 1 kg Izole Lak Pure Acrylic Primer should be mixed with 5 lt of water and must be applied to the wall by using brush or paint roller until the surface is saturated. Acrylic Putty must be applied for slight imperfections and Rustik Putty must be applied for subtler imperfections.
Silicon A4 must be reduced by using approximately 20% water and it has to be applied as two layers by a regular or lambskin paint roller.
12 hours are needed for the first coat to be dry. Before applying the second layer, Silicon A4 must be reduced by using approximately 5% water.
Proper paint roller is used downwards to give texture to the surface. Application must be made with care without applying too much pressure on the surface.
The surface becomes dry in 12 hours under the temperature of 20oC and 65% humidity conditons. It takes 36 hours to be resistant to impacts and dry completely.
For the application of Silicon A4, the surface must be stable and solid. So if it is applied in a new construction, four weeks are needed for the hardening of the cement.
