re laying old quarry floor tiles?

[ace llani]

I'm renovating the basement room in my old Victorian terrace.
The floor had no damp proofing, just the old fashioned 25mm thick tiles, laid touching, onto blobs of cement.

I dug the floor out, laid a DPM, 100mm Kingspan, 100mm concrete, so now solid, dry and level.

I want to re use to old tiles to keep the character, and I'm wondering what to set them with?

Guess ordinary floor tile adhesive would suffice?

I think that quarry tiles are normally set into a screed or cement mix, tile adhesive doesn't really have enough grab for quarries. I had a quarry tile floor laid in two rooms and they were laid onto a cement and sand mix with 10mm gaps all round, then when the cement/sand had set, the tiles were grouted with more sand and cement mix, in my case with black pigment added.

Due to various unplanned events I found that either cat piss or fresh orange juice will clean any cementitious residue on quarry tiles that remains after grouting. The problem I found is persuading the cat to piss with equal coverage across the floor. Orange juice (or diluted brick cleaner) is easier to apply...
