Mapei Eco Prim T Plus Primer is an all-purpose primer for interiors to improve adhesion of levelling compounds on all absorbent and nonabsorbent surfaces. It is a solvent-free, easily applied acrylic resins-based primer in water dispersion. It has excellent bonding, flexibility, water and ageing resistant characteristics. It is ready to use and easily applied by brush or roller.
Mapei Eco Prim T Plus Primer is suitable for preparing very compact and smooth cementitious renders and concrete floors before the application of levelling compounds. It is also suitable for preparing surfaces with traces of glue or old existing smoothing compounds, and gypsum, anhydrite, wood, marine plywood chipboard, ceramic or natural stone substrates before smoothing or applying cementitious adhesives.
Mapei Eco Prim T Plus can also be used as a bonding aid for cementitous smoothing compounds on substrates consolidated or waterproofed with Mapeproof ESM, Mapeproof One Coat or Mapeproof 1K Turbo.
Mapei Eco Prim T Plus should only be applied on internal flooring. If applying to wood, ensure it is moisture-stable. Do not apply on substrates subject to rising damp.
Mapei 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 treated with an epoxy or polyurethane membrane, such as Mapeproof ESM, Mapeproof One Coat or Mapeproof 1K Turbo, Mapei Eco Prim T Plus must be applied neat at least 24 hours after and no more than 7 days after applying one of the above membranes.
Consumption varies from 0.10 to 0.20 kg/m², depending on the porosity of the substrate and on how it is applied.
