Wet screed

[average]

Reading this thread and its got me thinking again! Few years back i had to remove a cracked shower tray that was bedded in a new;ly screeded floor that was down 5 weeks. All screed in the house looked cured however when i lifted the tray, the screed was still had that wet look and there was moisture under the tray. Its got me thinking about the 3 week time to start work ontop of the screed. Surely the moisture coming from under the tray could have a negative effect somewhere.

Have you ever considered that the reason there was moisture under the tray, was because it was cracked?

No, because it was never used ever. No water was in the system to go down the drain or even crack

I've just fitted some vinyl on a similar aged screed and used Ardex DPM1C on it. It can be laid on a floor with a moisture reading of up to 98%rh. check the spec, there may be a reason its not suitable but its worth looking at
