Different tile thickness

[andyandy2]

I've recently extended my kitchen into what was a downstairs bathroom with very old quarry tiles, these tiles have been taken up and new concrete base put in.

How long before i can tile on the new concrete floor approx 100mm thick (will be using pilkington 150 x 150 "quarry" tiles)

Also in the original kitchen are 6" x 6" red quarry tiles about 1/2 inch thick, these are on a good concrete base, but the concrete is slightly lower (thicker tiles) new tiles are about 9mm thick, is it ok to put a thicker bed of adhesive to join up to the old floor area (not sure if i've explained that very well)

Any help much appreciated

You can use adhesive to bed up to 10mm with powdered adhesive.

I'm still struggling with this has anyone else got any suggestions please

I have a small area of original concrete floor which has old style quarry tiles about 20mm thick, i don't have enough of the old tiles so will have to use the new "equivalent" which are only 8mm thick this is leaving me with 22mm between tile and concrete, the bagged adheshive will go to 12mm so not sure how to go about it
