We recommend installing ceramic and porcelain tiles with a high strength, flexible porcelain tile adhesive for reliable results.


There’s a vast selection of tile adhesives on the market, including powdered adhesives and ready mixed pastes. We recommend choosing a powdered adhesive rather than ready mixed adhesives for porcelain tiles. Although application takes a little longer, powdered adhesives create a much stronger bond.

Furthermore, the tile adhesive of choice should be flexible. In areas exposed to damp or humidity, or pressure such as footfall, flexibility is essential. A high quality, flexible porcelain floor tile adhesive will be able to withstand pressure and last longer.

Henkel Polybit offers an extensive range of tile adhesives, including Ceresit CM 17, a flexible ceramic and porcelain tile adhesive. This versatile adhesive is suitable for:

  • indoor and outdoor application
  • wet and dry areas
  • floor and wall tiles
  • ceramic, porcelain and natural stone tiles

If you’re applying the porcelain tile glue outside, you’ll need a higher adhesive coverage on the back of the tile.


Ceresit CM 17 is a flexible ceramic and porcelain floor tile adhesive. It’s also suitable for walls. For best results, work in dry conditions with air and surface temperature between 5°C and 45°C and follow these steps:

  1. Prepare the substrate. It should be clean, dry, even and load-bearing. If necessary, level uneven surfaces or remove coatings that could hinder adhesion. If the substrate is absorbent, apply suitable Henkel primer and leave the surface to dry for at least 2 hours before continuing.
  2. Prepare the porcelain tile adhesive. Pour the Ceresit CM 17 into a container with a measured amount of clean water. Mix thoroughly with a drill mixer until the liquid is smooth. Wait for 3 minutes, then mix again.
  3. Apply the tile adhesive with a notched trowel. If you’re working indoors, the mortar coverage on the back of the tile should be at least 65%. For outdoor work, use a minimum coverage of 90%.
  4. If necessary, remove stains. Fresh mortar can be removed with water, while hardened stains will need to be removed mechanically.

Once you’ve finished applying porcelain tile glue, wait at least 12 hours before grouting walls and 24 hours before walking on floors.
