Hi, If I am tiling over existing shower cubicle tiles is there any particular prepartion of the surface, apart from a good clean, thats required?
The existing tiles are applied to plaster board and cant be removed without replacing the plaster boards. As the entire boarded area will be tiled is it necessary to skim the boards or will it be OK to PVA the board, apply adhesive and tile straight on?
kbrownie - I am not looking to skim over the tiles. If i take the tiles off they wil damage the plasterboard so i will need to replace the board. My question is whether i need to skim the board before tiling bearing in mind the whole wall will be tiled, or just tile straight onto the board?
now got you,
Sorry for misunderstanding your querry. No need to skim if the whole area being tiled. But what I would suggest is that instead of sticking tiles onto the plasterboard, is after you have boarded out fix some 3/5mm hardboard onto wall then tile onto that, so when/if you decide to re-tile in the future it will not damage Plasterboard when you remove the tiles.
Don't use PVA use a tile primer on walls.
Best of Luck
tile straight on to the boards(no pva)
plasterboard will take 52kg per sq mt in wieght(tiles)
if you skimm the boards the wieght per sq mt drops to 38kg
this allows you to install bigger tiles
before tiling id advise to tank the walls go to a well known tile shop they can advise or see the projects section on the website
