Do I need to prime plaster before tiling?
Besides, do you need to plaster before tiling?
Tiling on plaster is ok, as long as your not fitting large format tiles. Still prime the plaster (obviously when dry) with acrylic primer. NOT PVA. Why plaster though..not really necessary.
Also to know, can you tile onto bonding plaster?
You don't tile onto bonding - finish plaster or one coat plaster, yes, but not bonding or browning.
9 Answers from MyBuilder Plasterers Yes. Even if the tiles come off easily,what you will be left with will hardly be suitable for a paint finish. Its very unusual for tiles and adhesive to come off and leave a good,clean surface that only requires a bit of prep.
