Thanks, will just stick to what i know as you suggest, is there any other you can suggest as my supplier (who employ 60 tilers) has told me he is stopping outside companys buying his gear, so I am on the look out for decent adhesive, i will still be able to get mapei but its a bit of a trek to the next nearest supplier, on my door step i can near enough get my hands on just about any other brands you could suggest. Thanks for any help
