I've just laid a latex screed over electric matt underfloor heating (about 8-10 mm). The matt sits on top of insulation boards (10mm), which in turn sits on top of a concrete floor).
The latex screed has cracked in multiple places and if I press hard with my foot, I'm not certain, but I think I see slight verticle movement.
Am I safe to tile on top of this? Tiles are 10mm thick stonker tiles (600mmX400mm)?
