Hi having work done on the house at mo - new floor being laid - top levels being styrofoam, underfloor heating, screed. I am doing whatever I can myself and shoot me down in flames but tiling has to fall into that category. What I am unclear about is whether I need a decoupling membrane? Total area is around 27m not sure if that is a large space or not. The other issue is how long should I wait before tiling and although I wince at the price of the membrane - will it enble us to tile more quickly. Do I really need to wait 2-3 months before tiling?

Welcome..

How long has the screed been down and it is in-screed heating you say .?

you could also use green screed as an adhesive!
how thick is the screed and what type of tiles are they?

What tiles will you be fixing

hi

wow that was quick. Screed is going down Friday - dry screed - sand and cement?

And I plan to use travertine 600X400


thanks

Normally you would need to commission the heating before you tile but by using a product like Ditra then you can tile early and without commissioning , but you must make sure the h eating is turned on very slowly and over a longer period than normal..

The Ditra membrane or similar is also a vapour equalisation membrane along with an un-coupling and anti crack membrane , so will cope with new stresses from the floor.

I cannot recommend enough that the membrane is used especially with stone and the fact that heating is being used.


The adhesive should be flexible and the same for the grout.

Dave thank you very much - that has told me what I needed to know _ i am kicking myself I didn't get a buy it now 30m deal on the ditra membrane for £180 last night.But hey.

that was cheap for ditra..

Yeah that's why I'm kicking myself!
I've been checking out regular prices- this was a one off
