My neighbour had an outhouse converted to a utility room with a new back entrance. The place was built in the 1940s and I suspect the concrete floor has no DPM. The people who converted it did a generally poor job (I’ve already done remedial work on the roof and guttering for them).
The issue now is with the ceramic floor tiles. Some have lifted in the heavy traffic area inside the back door. The others so far are staying put. I know that in theory one should redo it all, but ripping up the rest of the tiles isn’t an option, because there are units and appliances, and they wouldn’t want the disruption.
My question is what could I re-bed the tiles in, to give a reasonable chance of staying put? There isn’t any depth for a localised liquid DPM as well as tile adhesive. I was thinking of using a cement-based exterior adhesive onto the concrete (plus SBR?) and hoping for the best.
