Mapei Primer Lt 5Kg is a ready-mix, one-component cement-based primer designed to improve adhesion, support levelling and filling, and prepare substrates for subsequent coatings. It is suitable for interior and exterior use and contains anti-efflorescence agents to help maintain the substrate and inhibit mould growth.

It can be used on a variety of substrates, including tiles, terrazzo, wood, cement-based screeds, gypsum-based plasters, rigid insulation boards, and bituminous membranes.

It is a one-component product that requires no additional mixing—just add water to reach the desired consistency before application.

Apply an even coat over the cleaned, substrate to be primed using a brush, roller, or suitable applicator. The formula dries quickly under normal conditions; drying times depend on ambient temperature and humidity, after which you can proceed with the next coating or adhesive.

Mapei Primer Lt provides a high coverage rate, with coating requirements depending on substrate porosity and irregularities. In most cases, a single coat is sufficient, but apply extra coat if you observe any porosity or unevenness in the substrate.

The anti-efflorescence agents in Primer Lt help prevent salt migration to the surface and reduce mould growth, leading to a more stable substrate and better long-term adhesion for the subsequent flooring or tiling work.

Yes, it is suitable for interior and exterior substrates, making it versatile for a range of tiling and leveling projects.

Wear appropriate PPE (gloves and eye protection), ensure adequate ventilation during application, avoid prolonged skin contact, and store and dispose of any remaining material according to local regulations.

As a cement-based primer, it creates a uniform, scoured, and bonded surface that enhances the adhesion strength of subsequent tile adhesives and self-leveling compounds, reducing the risk of debonding on challenging substrates.

Ensure the substrate is clean, dry, and free from dust, oils, and contaminants. Fix any surface defects or loose particles, and allow the surface to dry completely before applying the primer. For bituminous membranes or other tricky substrates, verify compatibility prior to application.

Each has its own substrate compatibility and viscosity characteristics, so choose based on your specific substrate, climate, and adhesive system requirements.

Mapei Primer Lt is especially effective when preparing interior or exterior substrates for tiling, epoxy or cementitious coatings, or self-leveling compounds. It’s beneficial on slightly irregular or porous surfaces such as gypsum-based plasters, cement screeds, and bituminous membranes, as well as on surfaces like tiles and terrazzo where improved adhesion is desired before applying finishing products.
