Pro help please...
i have a large outside area 6msq approximately...ive just had a concrete slab pored by professional company (two weeks) and got a nice finish and fall, its clean and dry.
i want to tile in natural slate, ive done a few tests and a bed of 12- 15mm gives full tile coverage without buttering but the tests ive done i can get up after 24h..i have used both a sand and cement 1-1 mix with an additive as well as a proper tile adhesive.
my question is do i need to seal the slab with a PVA type product before attempting tilting? the tiles look pretty dust free before you ask.
thanks in advance
