Mapei Primer G | Synthetic Resin Primer
Professional Water-Based Primer for Floor Preparation & Surface Consolidation
Mapei Primer G is a synthetic resin-based primer in water dispersion designed to improve adhesion, regulate substrate absorption, and prepare surfaces prior to the installation of flooring systems, smoothing compounds, adhesives, renders, and ceramic tiles.
This professional-grade primer creates a flexible and compact surface film that helps consolidate dusty or porous substrates while improving the adhesion performance of self-levelling compounds, adhesives, and smoothing systems.
Primer G is suitable for use on cementitious, gypsum, anhydrite, plaster, terrazzo, fibre board, and similar absorbent surfaces where controlled absorption and improved bonding performance are required.
Its low VOC formulation and easy application make it ideal for both commercial and residential flooring preparation projects.

Coverage Information
Approximate consumption:
0.08 – 0.15 kg/m² depending on substrate porosity and application requirements.
Actual coverage may vary depending on substrate absorbency and dilution ratios.
Installation Overview
Substrates must be clean, dry, structurally sound, and free from oils, grease, dust, paint, wax, and loose material prior to application.
Primer G may be diluted with water depending on the application and substrate requirements.
Typical dilution examples include:
- 1:1 for cementitious substrates prior to smoothing compounds
- 1:2 for gypsum plaster anchoring applications
- 1:3 for wallpaper preparation
Apply evenly using a brush, roller, or spray system and allow to dry prior to subsequent applications.
