Low-viscous liquid consisting of water-dispersed SOKRAT styrene-acrylic polymer, miscible with water in any ratio. The evaporation of water creates a continuous, smooth and slightly sticky film. Mainly used as an additive for lime, lime-cement, cement and mortar mixtures, as well as for the production of spray plaster for permanently damp and alkaline environments. Also used as a primer under facade coating material and under sealants S-T1, S-T5 (requires dilution). When used as a primer, the dilution ratio with water is from 1:6 to 1:10.
