Mapei Eco Prim T Plus

Mapei Eco Prim T Plus is a solvent free, low odour acrylic primer for interior use to aid adhesion on all absorbent and non absorbent surfaces.

Best Uses

Mapei Eco Prim T Plus is a solvent-free, low odour, easily applied acrylic resin-based primer in water dispersion. It has excellent bonding, flexibility, water and ageing resistant characteristics. Eco Prim T Plus is an easily applied, ready to use light blue coloured liquid. It is applied by brush or roller. Eco Prim T Plus is not flammable and shows a very low emission of volatile organic compounds (EMICODE EC1 Plus), so it is absolutely harmless to the health of the installer and the end-user. It can be stored with no particular precautions.

Mapei Eco Prim T Plus is formulated as an all purpose primer for interior use to improve adhesion of smoothing compounds on all absorbent and non-absorbent surfaces. Mapei Eco Prim T Plus is suitable for use to prepare cementitious and gypsum based subfloors before the application of Mapei levelling products. It is also suitable for application to prepare surfaces with traces of glue or old existing smoothing compounds before smoothing or applying cementitious adhesives.

Mapei Eco Prim T Plus is ideal as a primer for preparation of surfaces in gypsum, anhydrite, wood, marine plywood chipboard, ceramic or natural stone before smoothing or applying cementitious adhesives. It is also ideal as a bonding aid for cementitous smoothing compounds on substrates consolidated or waterproofed with Mapeproof ESM, Mapeproof One Coat or Mapeproof 1K Turbo.

Application

Preparing the substrate
Substrates must be uniformly dry, sound, free of dust, loose particles, cracks, paint, wax, oil, rust, traces of gypsum or other products that can interfere with bonding. It is essential to make sure there is no rising damp present. All subfloors must contain an effective membrane to prevent rising damp.

Applying The Primer
Eco Prim T Plus can be applied with a brush or roller. It is usually diluted 1 to 2 with water when applying on cementitious or anhydrite surfaces. It is used undiluted on existing ceramic tile, natural stone, wood and adhesive residues (as long as they are water resistant). When the adhesive is completely dry it is possible to apply a smoothing compound or mortar. Drying time varies with the absorbency of the substrate and environmental conditions (temperature and humidity) approximately between 2 and 5 hours.

However, it is recommended not to wait more than 24 hours. If the product is used as a bonding aid for cementitious smoothing compounds on substrates consolidated or waterproofed with Mapeproof ESM, Mapeproof One Coat or Mapeproof 1K Turbo, Eco Prim T Plus must be applied neat at least 2 hours and no more than 24 hours after applying one of the above membranes.
