I have installed under tile heaters, how long should I wait before turning on the underfloor heating?
Installing under tile heating involves using screed as tile adhesive. The underfloor heating cannot be turned on until the flexible tile adhesive is fully dried. A minimum of 7-10 days should be allowed for this to ensure that the adhesive is completely dry. Turning the system on too early may force the screed to dry too quickly, resulting in an unstable subfloor.
It is important to follow the instructions and drying times advised by the manufacturer. Warmup can recommend Instarmac UltraTile flexible tile adhesive that has the fastest drying time and gives a high-quality finish.
