Thanks for the reply, substrate is concrete on the floor. The walls are block covered with what they call plaster here but it’s just sand and
cement. Some local products are tilefix, tuffstuff but it’s just adhesive and grout they sell. Can get some SA products, TAL, Progrip but not waterproofing kits etc just bonding agents, adhesive and grout.
It’s a single story property so ground floor, they don’t have timber floors here just a concrete foundation and they
tile straight onto it, no primer or anything even on walls!!!
