Primer G is a synthetic resin-based primer which, once applied to any surface, dry to form a flexible, compact, shiny coating which consolidates the surface, where needed. Primer G also improves the adhesion of smoothing compounds, paint, adhesive for wallpaper, adhesive for tiles and mortar for renders.

The film of Primer G on the surface of gypsum or cement, prevents any chemical reaction between sulphates and the cement alluminates of the tile adhesives which, in the presence of moisture, leads to the formation of the salt “ettringite’’ which is the cause of tiles breaking away from gypsum substrates. Primer G makes wallpaper stripping far easier and decreases the amount of glue used for paperhanging. When used before applying sprayable plasters,Primer G prevents over-rapid absorption of water by the substrate, prolongs finishing time and helps prevent shrinkage cracks.

WHERE TO USE

• For treating gypsum surfaces prior to fixing ceramic tiles.
• As an anchoring coat for gypsum-based sprayable plasters.
• To improve the adhesion of smoothing compounds on cementitious oranhydrite and gypsum-based surfaces.
• To provide uniform absorption in cementitious or gypsum surfaces
