Henkel Polybit Ceresit CM17 Cementitious Tile Adhesive 25KG

CM17 can be used on substrates such as concrete, brick, stone, plaster, and cement-based renders. It is suitable for walls and floors, including uneven surfaces, both indoors and outdoors.

CM17 is supplied in 25 kg bags. It offers good workability, does not slump or sag, and provides strong adhesion with flexibility. It is designed to be resistant to water and frost, making it suitable for wet areas and exterior use.

Mix CM17 with clean water gradually to a smooth, lump-free plastic consistency. Use a slow-speed mixer to avoid introducing air, and let the mixture slake briefly before applying. Mix only as much as you can use within the adhesive’s workable time.

Apply CM17 with a suitable trowel to a clean substrate, creating an even bed. For larger tiles, back-butter the tile and press firmly to ensure full contact with the adhesive. Maintain uniform coverage and avoid gaps under tiles.

Grouting should be done after the adhesive has properly set, following standard tile installation practices. The exact timing depends on ambient conditions, substrate preparation, and tile type, but do not grout until the adhesive has achieved sufficient strength for tiling.

Yes. CM17 is designed to be water and frost resistant, making it appropriate for wet areas such as bathrooms and kitchens as well as exterior applications.

Wear appropriate PPE (gloves, eye protection, and protective clothing). Use in well-ventilated areas. Avoid prolonged skin contact with uncured adhesive, and follow the product safety data sheet for storage and disposal guidance. Store in a dry place in its original packaging.

CM17 is ideal for interior and exterior tiling projects, including walls and floors, on uneven substrates, with ceramic tiles (porcelain, mosaic, quarry). It is suitable for wet areas and exterior facades where a durable, flexible bond is required.

Compared to CM11 Plus, CM17 offers higher flexibility and is geared toward larger or uneven surfaces, while CM11 Plus is typically used for standard interior tiling. CM16 is another high-performance cementitious adhesive with different substrate and tile coverage characteristics.

Use CM17 when tiling interior or exterior surfaces with ceramic tiles (including porcelain, mosaic, quarry) on uneven substrates or on areas requiring a flexible, water-resistant bond. It’s well-suited for walls and floors in bathrooms, kitchens, or damp areas, as well as exterior facades where durability and adhesion on irregular surfaces are important.

Allow the adhesive to cure fully as per standard tile installation practices before grouting. Keep the tiled area protected from heavy traffic and moisture until the adhesive has properly set. After grouting, follow normal sealant and cleaning guidelines for tiles and joints to maintain appearance and durability.
