Henkel Polybit Ceresit CM16 Cementitious Tile Adhesive 25KG

CM16 can be used on a variety of substrates including concrete, cement render, plasterboard, ceramic tiles, and anhydrite screeds.

Key features include high adhesion, good flexibility, water repellence, and good water vapour permeability. It also has an extended open time to help you adjust tiles for a perfect finish.

CM16 is suitable for wall and floor tiling in wet areas, indoors and outdoors, including use in swimming pools and bathroom areas.

CM16 is a factory-prepared, ready-to-use adhesive. Mix according to the product guidance, apply within the extended open time, and use an appropriate notched trowel to press tiles into place.

The product coverage is up to approximately 4 m2, depending on tile size and substrate condition.

CM16 has a shelf life of up to 12 months when stored in a cool, dry place.

As a cement-based adhesive, use standard PPE such as gloves and eye protection. Ensure good ventilation during mixing and application, and keep out of reach of children.

CM16 is designed for higher flexibility and open time, making it suitable for wet areas and outdoor use, whereas other variants like CM12 are general-purpose, CM17 is an extra-flexible option, and CM11 is another cementitious adhesive option. See the alternative product pages for specifics: CM12 (https://fepy.com/product/ceresit-cm12-cementitious-tile-adhesive-25kg), CM17 (https://fepy.com/product/ceresit-cm17-extra-flexible-tile-adhesive-25kg), CM11 (https://fepy.com/product/ceresit-cm11-cementitious-tile-adhesive-25kg).

Choose CM16 when you need higher adhesion with good flexibility and extended open time, especially for wet areas or outdoor tiling. For standard indoor tiling with typical substrate conditions, CM12 might suffice, while CM17 offers even greater flexibility for challenging substrates and large-format tiles. Compare the specific product pages for details: CM12 (https://fepy.com/product/ceresit-cm12-cementitious-tile-adhesive-25kg) and CM17 (https://fepy.com/product/ceresit-cm17-extra-flexible-tile-adhesive-25kg).

If tiles don’t adhere properly, ensure the substrate is clean, sound, and properly prepared; mix CM16 as directed; work within the extended open time; avoid excessive thickness and ensure tiles are firmly pressed into the adhesive. For wet areas, make sure surfaces are adequately prepared to prevent moisture-related failure.

CM16’s ready-to-use formula and extended open time can simplify the tiling workflow, reducing prep and adjustment time. Its performance in wet areas and outdoors can mean fewer call-backs for rework, potentially improving overall project value, especially in bathrooms, pools, and exterior tiling.
