How soon can tiles be laid on a new sand + cement screed? The screed is 75mm with under floor heating and the adhesive is evostik technik opf. We're under pressure to start within 3 weeks of installing the screed - is this too soon? What is likely to happen if the screed is not dry enough and the tilers commence regardless?
Thanks Patrick
No, that will be fine.
It is nice to let the screed dry completely after setting, as any cracks will appear then (repair with PVA)but not essential.
DO coat the floor with dilute PVA though before laying otherwise you run the risk of the tile cement (if a cement type) sucking dry too quickly and not setting properly.
This will also reduce the dust.
