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.

Mapei Rapid Set is for installing ceramic tiles on solid floors or walls, the rapid setting adhesive allows grouting after 2 to 3 hours and is water resistant and frost proof once fully cured.
