Product Information

Mapei Rapid Set is a non-flexible rapid-setting cementitious tile adhesive for the installation of ceramic tiles. Suitable for interior and exterior use on solid walls and floors.

Key Features

  • Rapid-setting - grout in 2-3 hours
  • High bond strength after 3 hours
  • Water-resistant and frost-proof once fully cured

Recommended Systems
Mix Rapid Set with clean water until a smooth, lump-free paste is obtained. Preferably using a mechanical stirrer. Use within 15-20 minutes, after which it will begin to set. A 20kg bag of Rapid Set should be mixed with 3.8-4.2 litres of water. Allow the mix to stand for a few minutes, then mix again briefly before applying. Do not wet tiles before fixing, if very dusty they may be wiped with a damp sponge. Rapid Set's open time in normal conditions is approximately 10 minutes, strong sun, drying wind, high temperatures or highly absorbent surfaces may drastically reduce this to a few minutes, therefore constant checks must be made to ensure no skin has formed and the adhesive is fresh to the touch. If a skin has formed adhesive should be removed and re-applied. Do not add water when adhesive has started to set. Adjustment of tiles, if necessary, should be made within 5-10 minutes. The tiles installed with Rapid Set should not be exposed to rain for at least 3 hours. Protect from frost and strong sunlight for 24 hours.

Exactly what I needed, at the cheapest price I could find (a lot cheaper!!). Easy and simple to mix, it does go off very quickly (as advertised, so make sure you are ready to lay plenty of tiles.
