Mapei Primer G is a water-based dispersion of special synthetic resins which, once applied to any surface, dry to form a flexible, compact, shiny coating to consolidate the surface. Primer G also improves the adhesion of smoothing compounds, paint, wallpaper adhesive, tile adhesives and mortar for renders. Primer G applied to the surface of gypsum or cement prevents any chemical reaction between sulphates and the cement alluminates of the tile adhesive which, in the presence of moisture, leads to the formation of the salt '’ettringite’ the accumulation of which causes tiles to break away from gypsum substrates.
