Mapei Acrylic Primer, 20Kg, Used for Cement and Gypsum Substrates to Improve Adhesion of Adhesives and Levelling Compounds

It can be used on a wide range of surfaces including walls, floors, plaster, cement-based substrates, concrete, masonry, and other common building substrates, for both interior and exterior projects.

The product comes in a 20 kg bag and is designed to be environmentally friendly and non-toxic. It offers strong adhesion, effective sealing of porous substrates, moisture resistance, and quick drying to prepare surfaces for paint or finishing coats.

Start with a clean, dry surface. Remove loose material, dust, and contaminants. Repair any cracks or defects, and ensure the area is free of substances that could prevent adhesion. For already painted or sealed surfaces, lightly abrade to improve bonding.

Apply an even coat using a brush, roller, or spray. Allow the primer to dry thoroughly before applying the subsequent coating. Drying times depend on temperature and humidity, but the product is designed to dry quickly and be ready for painting after the surface feels tack-free.

Yes. Eco Prim T Plus is formulated to be environmentally friendly and non-toxic, with low odor and suitable for use in spaces where people and animals are present. Always follow the product’s safety data sheet and use appropriate PPE.

You can paint over Eco Prim T Plus once it has dried to the appropriate tack-free state, which depends on ambient conditions. Ensure the surface is dry and free of any residual moisture before applying the finishing coat.

Both are multi-surface primers designed to improve adhesion and seal porous substrates. Eco Prim T Plus is formulated to offer strong moisture sealing and broad indoor/outdoor performance, while Eco Prim T shares core adhesion benefits.

Eco Prim U 600 is another universal primer option. Eco Prim T Plus emphasizes strong adhesion and moisture sealing for porous substrates, while Eco Prim U 600 may offer its own substrate compatibility and performance nuances. Compare them here: https://fepy.com/product/mapei-eco-prim-u-600

Ideal use cases include preparing interior and exterior walls, plaster and render, concrete floors, and masonry before painting or applying decorative coatings—especially on porous or humidity-prone substrates where strong adhesion and moisture sealing are beneficial.

Workflow: (1) Prepare and clean the surface, removing loose material and contaminants. (2) Apply Eco Prim T Plus evenly with a brush, roller, or spray. (3) Allow the primer to dry thoroughly to a tack-free state. (4) Apply your chosen finishing coat or paint after the primer is ready. Repeat the steps for any additional substrate areas as needed.
