Hi

Was hoping i could get some advice on correct procedure for tiling. I plan to remove the tiles which i suspect are mounted directly on to plasterboard. Its a timber frame house so was going to do the following:

Around the bath shower area i was going to use tile backing board. Do i need to install a vapour barrier? What thickness? and how to install?

The rest of the walls i was just going to use plasterboard which will be tiled. Do i need to install a vapour barrier or seal the plasterboard? Should i plaster or tile directly onto board?

Thanks

If it's a timber framed house the external walls will have a vapour barrier already in place behind the plasterboard. If you rip this removing the existing it'll need patching and taped at the joins prior to reboarding. The tile backing board is the best product but tbh plasterboard is more than ample to tile to if its not a wet room situation.
You can tile directly onto the plasterboard,it'll actually hold more tile weight than if you skim with plaster.

Thanks for the quick reply.

Can you reccommend what thickness vapour barrier i will need and where to get please? What is the best way of repairing. i.e can i overlap and staple to frame?

Should i seal the face of the tile backing board or plasterboard with a sealer?

should i apply joint tape to plasterboard and tile backing board and feather out where the joints meet?

Thanks again for the help

Can't argue with that as good general advice.. what size tiles and adhesive are you planning to use ??

Nothing to heavy justt 100mmx 200mm standard metro tiles. Someone mentioned using a cement based adhesive? Should i seal the face of plasterboard or cement board with a sealer mapei?

Vapour barrier is usually 500 gauge and in green rolls. This can be bought at your local builders merchants but you can purchase it online.
Don't seal the back or the face of the plasterboard with anything,unless the tile adhesive you are using and the type of tile you propose state so.
I'm assuming you are in Scotland with the house being timber frame?
If this is the case the house will be Ames taped and filled and not plastered. Use tapered edge plasterboard(green moisture resistant boards) and easifil compound and mesh tape to fill the vertical joints,then sand to a smooth finish.

i knocked of a few tiles on one or two of the walls to confirm if they were plasterboarded. One wall is plasterboarded and the other wall which ajoins the bedroom is honeycombed. Whats the best way to proceed? I couldnt seem to find a cavity behind honeycomb, seemed pretty thick.

bathroom wall adjoining bedroom wall. Tiles are coming of easy enough. Is it best to bond out hole, scrape back adhesive and plaster?
