Hi,
A tiler I am considering using has said he will have to put down a 10mm cement screed over the entire house where porcelain tiles are to be laid. He said the the levels have to be spot on for polished porcelain.(which I understand because of the square cut edges)He said they would find the highest point in the slab where the tiling is to be laid and work from that. My tiling starts at the entry and meanders into the other side of the house.
Is the screed necessary.?? if the slab is reasonably level to begin.
How do you acheive a good bond between the screed and the concrete slab as I am concerned over time that the screed might lift or crack.
