Mapei Primer G 5Kg

Mapei Primer G is a water dispersion of special synthetic resins which, once applied to any surface, dry to form a flexible, compact, shiny coating which consolidates the surface. Primer G can also improve the adhesion of smoothing compounds.

Key Features

• Very low volatile organic compound
• Helps prevent shrinkage cracks
• Prevent chemical reactions between sulphates

Surface Preparation
The substrate must be clean, dry and free from oils, grease and other loose materials. Cracks in concrete surfaces must be repaired first and anhydrite surface must be mechanically abraded.

Recommended Systems
1: As a treatment for ceramic tiles installed on gypsum : Stir the Primer G just before use, spread it uniformly on the surface with a flat brush without diluting it. If the gypsum plaster surface is especially smooth and glossy it is recommended to abrade it beforehand, once dry fix the tiles.
2: As an anchoring coat for gypsum plasters : Dilute Primer G 1:2 with water and stir well, spread the mix on the surface with a flat brush or spray pump. Apply the sprayable gypsum as soon as Primer G is dry.
3: As a primer before self levelling compounds : Cementitious substrates – Dilute Primer G 1:1 or 1:3 with water (depending on substrate absorption). : Ceramic, marble and non-absorbent substrates – Dilute Primer G 1:1 with water. : Gypsum based substrate – Use Primer G neat.
4: As a primer for wallpaper adhesives – Dilute Primer G 1:3 with water.
4: As a primer between smoothing layers – Dilute Primer G 1:3 with water.

Consumption
The consumption of Primer G will depend on the porosity and absorption of the surface. Normal consumption is between 0.1 and 0.2 kg/m²

Mapei Primer G is a resin primer suitable for use on absorbent substrates such as plasterboard or plywood prior to tiling, Application is quick and easy using a brush or roller.
