Hi,have to ceramic tile on an internal wall which has a sand cement render which has been float finsished in sharp sand BUT also painted. The surface does feel rough still but I am concerned if further preperation will be needed. This wall will form one side of a shower enclosure,ie do I need to take an angle grinder to the surface. Thanks
"just coat the painted render with a latex based primer or even PVA and allow to dry before tiling" :^O :^O - Yer on drugs mate :^O , and what will the tiles be stuck to - think about it bud , its a no-brainer :O
imo get as much of the paint off,any bits left, score with a stanley blade the prime with acrylic primer bal/mapei etc
