    Hi. We have just laid under floor heating, and have now put self leveling compound on top. Unfortunately we just checked the bag and read it said not to use to embed under floor heating - which is exactly what we've done.

    I assume that the under floor heating may crack the self level? We are planning on laying Amtico floor on top. We're not sure what exactly will happen.

    Should we rip is all out and start again? Unfortunately that will cost us hundreds to redo, so want to know if it's going to be a major oroblem if we don't.

    We laid wire UFH. The UFM was embedded with 6mm with the self level

    We think maybe adding a decoupling membrane on top might just give us some support if any cracks do appear

    You might be ok as I’ve had loads of builders use a water mix then I’ve put another coat of latex on top. best to put heating on for a day and see if any cracks appear

    Thanks. Although if it doesn't crack immediately does it not mean that it might still not crack in a few weeks/ months of consistent use?
