Mapei Flexible Waterproofing Mortar, Component A , 20Kg, Suitable for Negative and Positive Side Concrete Tanking - Grey

Planiseal 288 can be applied to cement-based plaster, concrete, cured plaster and masonry substrates, and other non-paintable, non-absorbent or slightly damp/uniform surfaces suitable for cementitious coatings.

It provides waterproofing and moisture vapor transmission control while offering good adhesion on prepared cementitious substrates. It is designed to work across interior and exterior conditions and helps prepare a reliable base for subsequent coatings or coverings.

Planiseal 288 can be applied in temperatures ranging from 5°C to 35°C. Ensure the substrate and surroundings are within this range and avoid freezing conditions during application and curing.

Mix Planiseal 288 using a standard rotary mixer, gradually adding the powder to achieve a creamy, workable consistency. Apply as directed for substrate priming and adhesion, ensuring an even, wrinkle-free coating on the surface.

Drying and recoat times depend on ambient temperature and humidity. Allow the surface to become dry and tack-free before applying subsequent coatings or tiles, and follow any surface-drying cues provided on the packaging or by your installer guidelines.

Planiseal 288 is supplied as a 20 kg grey bag, designed for easy handling and mixing with standard tools to achieve the desired substrate preparation result.

Yes. Wear appropriate PPE such as gloves and eye protection, ensure adequate ventilation, and follow local safety regulations. Avoid prolonged skin contact and wash exposed skin after handling. Keep away from children and pets.

Planiseal 288 is a vapor-permeable waterproof sealant and adhesive for cementitious substrates, often used to prepare and prime a surface before finishing. Planiprep Fast Track is a separate substrate-prep product from Mapei designed to condition and prime surfaces prior to tiling. They can be complementary in a project, with Planiseal 288 focused on moisture control and adhesion preparation, while Planiprep Fast Track targets surface conditioning for a uniform base.

Planiseal 288 combines waterproofing, moisture management, and adhesive-priming capabilities in one product, potentially reducing the number of products needed and simplifying stock for a project. Its 20 kg bag format is convenient for mid-sized jobs, and its suitability for a range of substrates helps minimize material variety while maintaining performance.

1) Prepare and clean the substrate, removing dust, loose material, and contaminants. 2) Mix Planiseal 288 with the recommended water to a creamy consistency using a standard mixer. 3) Apply the coating evenly to prime and seal the substrate, ensuring a uniform, wrinkle-free surface. 4) Allow the surface to dry to a suitable state before continuing with tile, coating, or other finishes as planned.
