I'm looking for advice as i've been told different things by people and read so much forums etc my head is in a spin!!
I'm installing a new bathroom in my flat to refresh it cause i need to sell, with new suite and tiles going in. When i started removing old tiles, whatever they were stuck onto fell to bits so i am now back to the brick!!!
Me and may mate who has some diy experience were planning to put pva onto the brickwork, then dot and dab plasterboard onto the wall then, pva again, then tile onto the plasterboard.
However, after speaking to others and reading this forum, this is probably not going to work.
I'm trying to keep costs down to a minumum as i'm selling, so is what i've suggested enough?? I'm worried about moisture from shower, i've a bath/shower not a seperate shower.
Any info/help would be gratefully appreciated and by the way my tiles are pretty heavy and due to size, door frame, window and area for bath i cannot put in studwork.
compared to my last tiles these things are heavy, they are 300x440x9mm.
Should i still pva my brickwork or do i need to bother? The thing i'm worried about is moisture, if i use normal plasterboard should i coat this with anything before tiling to make it waterproof?? Or should i just buy waterproof plasterboard, or would it be cheaper waterproofing normal plasterboard with some kind of stuff (technical term) lol
Also, i've bought evo-stik tile adhesive and grout, which apparently is waterproof, mould resistant etc, but my mate says to stay clear of combined adhesive and grout and to use seperate?
I thought this was gonna be not too bad, but the more i read the more confused i get that i don't have the right stuff and i'll make a rubbish job!!
Don't think you need to pva brickwork before dot and dabbing plasterboard but one of the plasterers on here may advise better. if you are going to be tiling a wet area i.e. shower area then it is always advisable to tank te area first. The genrally preferred method on here is to use a mambrane system from the likes of Durabase or Schluter. You stick this to the plasterbaord forst with cement based adhesive and then tile on top with cement based adhesive.
Tiel and Grout in 1 bucket is not a good idea. adhesive has a differretn function to grout and unless it is epoxy, you should have separate products for each function.
Never hear of waterproof plasterboard, you thinking of tile backer board?
Tank the area? Is that that bal wp1 stuff that folk on this webwite refer to? Does that make normal plasterboard waterproof?
I thought you could buy waterproof plasterboard???......maybe not!!! lol
God this is turning out to be complicated, maybe best to bite the bullett and pay someone to plaster?!
I thought it would be as easy as dot and dabbing plasterboard then sealing it then putting up tiles, well that's what my mate led me to believe!!!
It pretty much is, you just need to seal (waterproof) the plasterboard with a membrane system before tiling. The BAL system is of the same sort, but Durabase CI from wetdecs our wetrooms sponsor is probably a better option.
I think you mean the moisture resistant plasterboard(green) which is no substitute to tanking ordinary p/board,
As you are boarding out anyway why not substitute plasterboard in shower area only with tile backer board, it will probably work out cheaper than having to buy a tanking kit
Certainly dont use pva before tiling. you will need a cement based adhesive for tiles that size,depending on which manufacturer you go for they will have a primer to suit
You only need to tank the shower area of the bath.....A membrane will be quicker and cheaper....Use a flexible cement based adhesive....this can then be used on the walls and floor if suitable prep work is done on the floor..
So the tank stuff, can i just tank the plasterboard around the shower and then tank this bit, then leave the plasterboard that won't really get wet normal. Is the tank a thin application, so that i can do this or is it thick that will make things uneven when tiling.
The durabase stuff is pretty thin and should not make any difference to the levels for the tiles if properly applied. yes just tank the area that is going to be getting quite wet. The rest should be ok.
