Following installation the environment must remain sealed for 2 days.
The screed should be protected from sunlight & frost during this time.
Do not cover with polythene.
Storage of materials on the screed surface, accidental exposure to water, humid or cold environments will delay drying.
When installed over under floor heating systems the screed must be heated prior to application of floor finishes. This can commence 7 days after installation. Heating should be gradual in 3-5°C increments. At no time should the temperature exceed 50°C.
Before tiling over underfloor heating a 3 week cycle is recommended; 7 days running up to temperature, 7 days at your operating temperature and 7 days cooling down. This will help condition the screed to movement without the floor covering in place.
Heating should not be switched back on again for a further 14 days after tiling, it can then be brought up to the operating temperature gradually.
EasyFlow screed will dry at a rate of 1mm per day for a thickness of up to 40mm and then at 0.5mm per day for anything over 40mm.
IT IS ESSENTIAL TO ENSURE THAT THE SCREED IS FULLY DRIED OUT PRIOR TO APPLICATION OF FLOOR FINISHES.
When applying adhesives or cement based products the screed surface MUST be primed with a primer recommended by the manufacturer.
It is advised that the screed be lightly abraded to aid absorption of the primer.
