Mapei Primer G 1kg – Box of 12

Primer G is a synthetic resin-based primer that dries to create a flexible, compact, and shiny coating on various surfaces, effectively consolidating them where necessary. This primer enhances the adhesion of smoothing compounds, paints, wallpaper adhesives, tile adhesives, and render mortars. Additionally, it forms a protective film on gypsum and cement surfaces, preventing chemical reactions between sulphates and cement aluminates, which can cause ettringite formation and subsequent separation when moisture is present. When used prior to wallpaper application, it reduces substrate absorption, decreasing glue usage and simplifying wallpaper removal. It also extends workability time for sprayable plasters by preventing rapid water absorption and helps minimize shrinkage cracks. Moreover, it reduces air bubble formation and slows drying in self-levelling compounds, making the application process easier. Importantly, Primer G is non-flammable, allowing safe use in closed and unventilated spaces without special precautions.

Key Points:

Surface Consolidation: Dries to form a flexible, compact coating that strengthens surfaces and improves adhesion for various materials.

Chemical Protection: Prevents harmful chemical reactions between sulphates and cement aluminates, safeguarding against ettringite formation in moist conditions.

Efficiency in Application: Reduces substrate absorption during wallpaper application, minimizes glue usage, and eases wallpaper removal, while also extending workability for sprayable plasters and self-levelling compounds.

Safety: Non-flammable and can be safely used in enclosed spaces without the need for special precautions.
