Dear all
I would very much appreciate your input into the following situation:
Thurs/Fri morning - tiles put on wall using 3 bags of a store's own brand powder adhesive which is supposed to set in 2 hours
Fri - late afternoon, grouting
Monday morning - polish grout off, see that tiles have slipped - wonky uneven grout lines (as opposed to Friday) plus significant lippage. Excess adhesive put to one side to harden before disposal is like silly putty - nowhere near going off. (The excess eventually hardened after 10 days.)
Various tiles taken off wall - it appears that 1/3 of tiles stuck no problem, on the other 2/3s, the adhesive was as unset as that left out.
Two of the adhesive bags had the same batch/manufacturer code, one was different.
Tiles put on by professional tiler.
Do you think that a reasonable conclusion might be that the two matching code bags were faulty? Store is adamant that their adhesive is not at fault.
Many thanks
So the grout was left over the weekend before cleaning off??????
