Studies were performed on the production of highly dispersed carbonate-silicate fillers by the precipitation procedure. The fillers were subjected to surface modification employing for this purpose either the dry or the wet technique. For the modification various acrylic derivatives and silane coupling agents were used. The obtained products showed variable hydrophobic character and particle homogeneity. The modified and the unmodified carbonate-silicate fillers were used in facade acrylic paints and in silicate paints. Application of the fillers promoted production of facade acrylic paints of properties consistent with the norms an of silicate paints of a good density in the formulation system.
