    Hi,
    I have latexed 20mm flexable screed over electric ufh which was set onto a decoupling membrane. Its going to take a while to fully dry but here is my question. Could I dpm it with a resin based dpm wait for it to dry then lay lvt directly to the dpm? If so which dpm would work for this? I will obviously make sure r/h levels are correct first etc.

    Thanks in advance

    Tim

    Should of done the Dpm under the decoupling boards
    Why do you want it above ? What’s compound did you use over the wires ?

    It's not a damp issue other than the latex itself isnt dry and the kitchen is being fitted on Friday.

    It will be fine by Friday mate. Also you can’t put a liquid Dpm over a water mix compound as it isn’t moisture tolerant.

    Most. There are a few I’ve heard. But in most cases you can only go over a latex type.
