Removed tiles, what a mess, HELP (yet again lol!)

I know there are other posts but struggling to follow different advice from different posts etc:scratch:

Well I've started removing the wall tiles from the bathroom wall. They have taken chunks out of the plaster board, paper backing has torn off in areas, and some of the tile adhesive is in place still.

When all complete what is the best, cheapest and easiest thing to prepare the wall for me to tile it again?

The thought of pulling down the wall and putting new plasterboard up scares the life out of me! I've also never known a tiler do that when I've used them in the past etc?

Thought I'd post a picture! Thing is as well, I've read about replacing the plasterboard but only tiling to the current height, not entire wall?!

then cut the plasterboard at just below the height you will be tiling to! and replace that part only, oh and dont skim it as plain plasterborad carries morekgs per meter than skimme does!
Just beware for cables running behind it!
if its stud wall just screw new PB onto studs
If its D&D just hack off old dabs and re dab to get the 2 boards flush at the joint!

Ok so (being thick) I find the frame in the wall, cut to that and then replace that with new standard plaster board (gypsum?) by screwing it into vertical and horizontal frame?

Then, on new plaster board, I just place the tiles? or do you have to prepare it somehow?

(What is D&D and "dabs"?)

D&D =dot and dab its a method for fixing plasterboard to blockwork!
mix an adhesive and DOT it onto the boards the DAB the boards onto the wall!

You can prime the plasterboard with BAL PRIME then stick your tiles on! but not neccaseryif you use a decent addy!

If its a stud wall you will only have verticals (studs) so it wouldnt hurt to insert noggins(horizontals) where you cut half lapping the old and new to add som stability to the joint between the two!

Thank you that all makes sense now

I'd be tempted to use tile backer board rather than plasterboard behind tiles, depends on how wet it is going to get.

Fix with correct screws just as you would PB.

Tile backerboard is really only worth using in SHOWER enclosures! its not cost effective or necessary to use it anywhere else in a bathroom, ive fitted loads of bathrooms before hardbacker orthe likes were introduced and they are all still going strong, as mostly its down to the GROUTING and SEALING when your talking waterproofin tiling !

If you are using small tiles.........that plasterboard lightly skimmed over will be ok. Could skim it with floor cement.

DONT skim plasterboard before tiling! large or small format, its a waste of time and money!

Replacing the board will make the tiling much easier, giving a perfect finish with little fuss. Aquapanels are about £ 12 each and are therefore used economically i.e where the bath or shower meets the tiles. The Aquapanels can be sealed to the bath or tray which prevents leaks downstairs in the event of a tile or the grout failing. If plasterboard gets wet, it needs replacing which means cutting it out and having a plasterboard join low down in a wet area, which is succeptible to cracking. Aquapanel (or Hardibacker) are both 12mm thick so you can use them in conjunction with 12mm plasterboard rather than aquapanel the whole area.

Agreed................but the picture shows minor scrapes.........so a light going over would make it easier.

You or I would rip off and reboard...........but the average DIYer would not

it does depend on the size of tile

If you are going to level up with plaster, surely Bonding rather than Skim would be the only sensible choice?

marc1106 · Post by **marc1106** » Mon Jan 19, 2009 8:49 pm

No joz bonding is too soft and absorbhant to hold tiles with a decent adhesion, you should tile onto skim or straight onto plain boards!

Only-me i agree with you on this but know the OP has been told its somthing he can have a go at and add another string to his BOW

Now you see if I could skim or whatever it is your on about (lol) I would by the sounds of it!!!!!!

But I don't and sticking some board up sounds doable.

Thanks all very much, massively appreciated.
