1: You are tiling to another fixers tiling and do not know how well they are fixed..
2: This is over wet ufh and 2 layers over that will expand at different rates ,thus possibly causing a delamination issue.
3: i cannot see the tiling ripping up the screed, they will break away and most likely leave adhesive residue on the screed..
Only you can see the job at face value and only you can make that executive decision to over tile or not..
On another note, very strange the customer did not contact the first fixer to re-seal and again why the customer did not contact tiler when this second person naffed the floor up..?... seems really strange to me but nothing to do with your side of it, just curious..
Thanks for reply, all very fair points.
Yes, not sure about the mysterious first tiler.
I think a test removing some tiles is in order, and if they come up easily / with little damage, then I'll go for a full removal.
Does anyone else have an opinion of using encaustics in a high traffic area of a house, for a family with young children?
