Primer Coat – STYRMANN ST 60. Application: grounding porous and absorbent concrete and ceramic foundations, cement panels, aerated concrete panels, gypsum-paper boards, gypsum surfaces, calciferous cement surfaces, etc. The emulsion penetrates deeply into the oldest and driest foundations, which become significantly reinforced. It improves adherence of the applied plaster and prevents diffusion of contaminations between the foundation and the new coating.
