Do you have detailed description on what this does and how it should be applied?
David Sowter | 21 May 2020

Hi David,
Synthetic resin based primer in water dispersion.
Treating gypsum or anhydrite surfaces prior to installing ceramic tiles and stone material with cementitious adhesives or levelling. The surfaces to be treated must be clean and porous.
Dilute Primer G with water from 1:1 to 1:3 to protect old floors before levelling, to fix the residual dusting and to provide even absorption of substrates prior to levelling or laying. Apply on perfectly dry gypsum or anhydrite surfaces (residual moisture content less than 0.5%).

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.

Kind regards,
Paula Podgorska Reply | 21 May 2020
