    Hello,

    We're having LVT installed over a mainly suspended timber floor, that has a section (about 2.5 x 1 metre) of quarry tiles which are presumably sitting essentially just on dirt (house built in 1908 so not likely to have anything damp proof beneath). There is also a tiled hearth section that is essentially similar.

    An installer came round and suggested that he'd ply board the timber sections (6 mm) and latex over the tiles to smooth it all out.

    Will latex stop any moisture from rising through the tiles and affecting the glue? The tiles don't *seem* obviously damp but obviously that's based on looking and touching, not any actual measurements!

    Thanks!

    Ideally they should be removed and expoxy DPM applied then primer then smoothing compound

    Just be aware that epoxy dpms are carcinogenic
