How long to wait until tiling onto 75mm screed

[Geoff Thacker]

If this was my job and time wasn't an issue I'd put a hydrometer on it to make sure the screed was dry, in my opinion a 75mm s&c screed could take up to 3 months to completely dry, if time is a issue I'd use a DPM before tiling with SPF iv used tile masters DPM in the past for this exact problem. Worked a treat ... Geoff
