Primers to be used under polysilicate (low-alkali) products
Main advantages of primers under polysilicate products:
- high adhesion to finishing materials (top coats);
- limited and equalized surface absorption;
- reduced chalking;
- surface impregnated mineral substrate;
- easy application and lower consumption of top coats (renders) and paints;
- colored primer used under renders reduces the effect of seeing through substrate.
