Mapei Osmotic Waterproofing Mortar, 25Kg, Suitable for Internal and External Concrete and Masonry Tanking - White

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.

Store Planiseal 88 in its original, unopened packaging in a cool, dry place. Keep containers tightly closed when not in use to prevent moisture ingress. Shelf life is defined by the product packaging; always refer to the date on the packaging for the best guidance.

Planiseal 88 offers fast setting and strong adhesion, which can reduce installation time in damp environments. When evaluating value, compare coverage yield, open time, and the need for faster grouting against other mortars available on Fepy to determine the most cost-effective option for your project.

Planiseal 88 is a cement-based tile fixing mortar focused on bonding tiles and protective coatings, while KERALASTIC 11 is a waterproofing/plastering additive/system used to improve moisture resistance and substrate preparation. For projects needing a bonded tile bed with moisture management, Planiseal 88 provides the mortar strength, whereas KERALASTIC 11 contributes to the moisture protection of the substrate.

KERAFLEX PLUS is a flexible tile adhesive designed to accommodate movement and thermal expansion. Planiseal 88 is a cement-based mortar optimized for fast setting and strong initial bond. For installations requiring elasticity or movement accommodation, KERAFLEX PLUS may be preferred, while Planiseal 88 excels in rapid, secure tile fixing with early grouting capabilities.
