Features
Reduce porosity and absorption. Provides uniform absorption on the surface. Extends working time for cementitious and gypsum based finishing products. Fixes the dusting parts on the surface and improves the strength and solidity of the surface and adhesion of tiles, plasters, wall papers. Prevents shrinkage cracks. Forms a flexible, compact, shiny film. On the surface of gypsum, prevents chemical reaction between sulphates and the cement aluminates of the tile adhesives, in the presence of moisture, leads to the formation of salt named “ettringite” which is the cause of tile breaking away from gypsum substrate. Prevents over-rapid absorption of water by the substrate. Solvent free. Ready to use. Easily applicable with roller and brush.
