ufh question.

[Andy Allen]

got a job to look at tomorrow, the customer has ripped up his old tiles and slc the floor not using flexable latex, would it be ok to lay the thermal boards on top of this, then the ufh and slc.......or will the slc he laid crack up..

As long as it was laid ok.. primed etc and not exceeded the depth it can cope with, then ye it is ok.. the heat will be on top of the boards and not under.

 

[Andy Allen]

thought so..........but worth checking..

I take it this is a screeded ground floor and not an upstairs wooden floor?
