Criteria of using water-dispersion synthetic polymers for interior finish of pre-plastered or pre-puttied premises are determined. Acrylic and styrene-acrylic dispersions, due to containing ion carboxylic groups, are exposed to the alkaline impact that requires their study in the course of their interaction with high-alkaline cement systems. To analyze the degrees of influence of an alkaline agent, rheological peculiarities of dispersions have been determined with increasing the PH level. It is revealed that acrylic dispersions have higher viscosity at high shear rates; styrene-acrylic dispersions are the least susceptible to the impact of calcium hydroxide, have low viscosity at an equal concentration and size of polymer particles. These properties are used for producing efficient water priming compositions of deep penetration on the basis of styrene-acrylic dispersions, and, on the basis of acrylic dispersions, for producing paints with a high content of pigments.
