Base preparation

The surface needs to be dry and clean, without dust, dirt, oil or any other greasy spots and must be completely clean. In case of chalked or particularly absorbent plasters we suggest to apply the base Siloxan Q with water.
We always suggest to use this treatment when the surface you want to paint presents tough absorbance diversities.



Dilution in weight with water: the first layer until 40%, the second until 20%. Apply the second layer after 8 hours minimum from the first. The application can be done with a brush or with a wool roll.
