Quarry floor, no damp course.

[Andy Allen]

Look at a floor today
Problem is it's a 200 year old house, no damp course and quarry tiles down.
They want porcelain tiles fitting on top the quarry tiles.......obviously not keen on that idea......but before I bin the job....anyone got any suggestions on how it can be done..?

Sort mate was just getting home.
From memory, or tho I've never dealt with it.
As long as it's not a lime screed, cos they must be able to breath, and that your sub floor is all good sound and load bearing.
Liquid dpm as Andy above says, then you can level over it with Arditec NA or similar. (I'm sure Isomat do liquid dpm and a leveller that'll go over it)
Then tile it.
I stand to be corrected tho.

Sorry Marc it's Arditex Na

Ultra tile do a liquid DPM, and a product called surpress it, spoke with a rep recently that similar situation recommended using suppress it, am doing it next week, should get the stuff delivered tomorrow, but they have a data sheet online for it

If your using the epoxy dpm such as tilemaster, I can't see why a regular leveller wouldn't be fine on top.
