Mapei Osmotic Waterproofing Mortar, 25Kg, Suitable for Positive and Negative Side Concrete and Masonry Tanking - Grey

Mapei Planiseal 88 is a ready-to-use, medium-bed, asbestos-free, cement-based flooring mortar designed for fixing ceramic, porcelain, and natural stone tiles, and for protective coatings in damp environments. It provides strong adhesion and is suitable for internal and external tiling on cement-based substrates and traditional waterproofing screeds.

Planiseal 88 is intended for fixing tiles on cement-based substrates and on plaster prepared with compatible systems, as well as traditional waterproofing screeds. It also works for internal and external tiling in damp environments.

Planiseal 88 features ultra-fast setting and excellent adhesion, which supports faster grouting thanks to its early water-repellent properties.

The mortar is yellow by design to act as an easy reference for the wetting process during application. This assists with spreading, trowelling, and shaping the mortar smoothly.

Planiseal 88 is a ready-to-use cement-based mortar. For best results, spread it evenly on the substrate, use the appropriate trowel to achieve the desired thickness, and shape the bed to receive tiles. Ensure substrates are prepared and compatible with the system, and follow standard tiling practices for a secure bond and proper alignment.

Key attributes include: ready-to-use, medium-bed tile mortar; asbestos-free; cement-based; suitable for ceramic, porcelain, and natural stone tiles; internal and external use; compatible with cement-based substrates and plaster prepared with compatible systems; fast-setting with early water-repellent properties; yellow coloration for wetting reference and good workability.

Planiseal 88 is ideal for fixing tiles in damp environments, both indoors and outdoors, on cement-based substrates and plasters prepared with compatible systems, as well as traditional waterproofing screeds. It can be used with ceramic, porcelain, and natural stone tiles and for protective coatings in damp settings.

Planiseal 88 is a cement-based mortar and is asbestos-free. Wear appropriate PPE such as gloves and eye protection, ensure good ventilation during mixing and application, avoid skin contact, and wash thoroughly after handling. Store in a dry place away from moisture and out of reach of children.
