    hi guys just a couple of quick questions..is it ok to tile straight onto plaster board walls? iv just bought a big tub of tiling adhesive for the job..also when your tiling into a corner and need to cut that last tile in half do u start the next wall with the remainig tile or do you use a new tile?
    thanks for any replys guys

    Pva the plasterboard first.

    You need to set out each wall. i.e. using two half tiles on one corner may look good for that corner but if it means the other corner needs only an slither of a tile it will look ****!

    Use a tile specific primer and then you can tile straight on to the p/b.

    you say in your op that your using "a big tub of adhesive"

    what brand is it?
    what size of tiles are you fixing to walls?

    dont use pva as the other guys have stated.
    tile onto p/b "dont" skimm it ..bring weight issues into tile fixing.

    let us know ansewers to the above 2 questions.
    as for setting out centre your walls and walk tiles into corners to see what size of cuts you will have.
    any windows tile from centre of these.

    hiya..the adhesive is wicks extra strong wall tile adhesive and the tiles are 10 inchs by 15 inchs..its a new downstairs loo and the walls have been plasterboarded out..so is it fine just to tile straight onto the plasterboard walls?

    Do not PVA and you can probably chuck that tub of adhesive away.

    the adhesive you have imo "is the not the best" or good for tiling mate.

    your tile sizes are 255mmx390mm..any tile over 300mm you should be using a bagged adhesive if you use the "tub addy" you will be waiting for ever for tiles to set mate.

    tubbed addy is a dispersion addy sets with air contact.
    bagged addy sets with a chemical reaction.

    imo use a bagged adhesive here mate.

    when ever you use a bagged addy you should always prime walls/floors with a recomended acrylic primer.

    when using a "tubbed" addy there is no need to prime as the tubbed addy already has the acrylic in it.

    member mate if you want it done and done right this is the time to do that.:)

    also yes just tile sraight onto the "bare" p/b, dont skimm it.

    best of bud.

    Why exactly is everyone jumping on the do not use pva bandwagon.Has anyone had experience of tiles failing on pva because I haven,t.

    PVA is fine until moisture gets behind when it reactivates and then releases its bond. NEVER use PVA as a tiling primer.

    don't use PVA. ever. just out of interest have you tiled the floor / will be tiling the floor? don't forget to allow a gap for the ply [if needed] and thickness of floor tile. and always tile from the middle of the wall. with cutting. measure twice. cut once.

    If pva is fine until water gets behind it then pva is fine for the op,why would water get behind the tiling in his toilet.
    In a shower or round a bath,fair enough,but in my opinion saying do not ever use pva is scaremongering.

    adhesive companies will advise you not to use PVA. If you give someone advise it should be the right advise.

    The pva is not gluing the tiles to the wall,it soaks into to the plaster or board.The emporer and his new clothes springs to mind with some on here.
    As I said before how many of you lads are coming across tiles droping off walls because of pva,which is widely used.
    To summarise: On a wall not subject to constant wetness ie,kitchen bathroom and toilet walls pva is a perfectly adequate to bond the walls before tiling.
