Hi all, I have a kitchen floor I'm replacing the tile in. i popped a few tiles and it looks like there's cement with wire mesh that the tile is stuck to (sometimes they pop off without the cement, sometimes with). underneath the mesh looks to be support beams. Before laying the new tile how should i prepare the floor? it's an older building (1890, 1900 in nyc) so I don't want to rip up too much if I can avoid it.
-thanks in advance! -Dave
