Well i've just returned, and had a tile up, the latex has pulled away from the ply. I don't think i have ever seen that happen before, the latex is well with-in normal thickness 5-10mm, but it has cracked and lifted. it appears to be half the floor that is effected. I have asked the customer if they have had any works done to the house, which they assure me they haven't. I no they have had a set of french doors fitted to the rear, so i thought maybe the building company used stilts to support ceiling which may have pulled the floor out of shape. either way, the only for this to be fixed is to have the loose tiles removed and re-layed. Is it possible to hack away the loose latex around the UFH (about 3m2) and put another coat of latex down?
As I'm still unsure wot has caused the latex to lift, I'm worried that I'll do all this work, and it will happen again?
I want to put this right, but at the moment it has cost me a days wages so far, and i don't want to continue the works for free, if its not my responsibly.
