Walls slightly out lol

[stu-180]

Just stripped out my own bathroom (been putting it off), I knew the walls would be out but its a bit worse than I thought !

Pic 1 show the old tiles coming off and the 40mm of bonding (that was NOT stuck to wall, think the grout was holding it all up !



Pic 2 shows how badly the wall is out -



This is the wall that will have a new shower fitted so not really sure what to do, im using big 30cm x 45cm tiles so the walls really need to be good, would it be worth getting some of that cement board and screwing that to the wall and then give it a skim to level it off ??

Any ideas ?

If you use cement boards you dont need to skim them as that would lower the weight tolerances. Are you sure its not that wickes level thats out?

beat me to it Dom!, I'd be inclined to dot and dab some plasterboard on that wall, and then tank it

[stu-180]

lol, you never know, it doubles up as my hammer !

Would I need to bond the wall out to get the level up and then put the cement board up ? to bring it flush ?

Or maybe key the wall a bit better and just bond it again ??

[diamondtiling]

The render is off the wall judging by your pictures, you need to remove it and then use plaster board. Bond the wall with mapei g before fixing boards.

If you dot and dab plasterboard, as Doug suggests use the correct adhesive eg. Gyproc or the like

Thats actually old bonding, the blue wall showing through is the original wall, will give boarding it out a try then, is mapei g a bonding mix ?

[Scott]

Prime before dot and dab? Ive never primed and never had a problem with that stuff, it sticks to everything

Mapei primer G is a primer (SBR)

[whitebeam]

If your doing boards directly onto a finished wall Gyproc Sealant

Morning everyone, forgive my ignorance but how do I go about tanking it ?

Lets say I dot and bad some plaster board on the wall and square it all up.

Its only the bit over the bath that it is 'out' so would be about roughly 2ft x 5ft (one single piece of cut plaster board)

Should I just get one of the BAL kits and waterproof the plaster board wall and then the wall that runs parallel with the bath ?

Is this stuff easy to use ?

Cheers

Yiou could either use the tanking kit mentioned or many others of the same. I prefer the membrane system myself though, I just cant seem to trust a paint on system. So I use Dural WP

Correct

The Mapei shower kits with the mapeigum seemed ok to me. Easier to put up as its just brused or rollered on. It does hoever take longer to do as the boards needs priming first then 2 coats so with drying time in between it could take a while.

Morning all,

Quick up date on the project, Plumber was in all day yesterday, poor old boy had a bit of a mare in the end, he needed to -

Plumb in new power shower pipe work, cut and re-plumb new sink and bath waste pipe (was old and furred up), and reposition radiator pipes.
The waste pipe proved a bigger job when he fitted all the new pipe work and there was still a blockage ! (had to cut the pipe and rod it out).
He then put some acid down the sink to try and finish off the blockage in the galvanized pipe work but this took all the chrome off the waste in the sink !! lol
Then to cap it all off he dropped his hammer and smashed our toilet !

(He is a good plumber, just 'one of those days', so he will be back with a new pan for us).

Have decided to have the wall bought to level by plastering it.

Have bought a BAL-WP1 tanking kit, has anyone used this before ? easy to use ??

Will keep this updated with photos as I go so you can all have a butchers.

(Here is some of my demolition work)

That is a bad day for your poor old plumber

[Phil Hobson]

I have just used the BAL tanking system, ( I usually go for Mapei) but could not source in time. I must admit I was very impressed, with the BAL

[FreeD]

I was once told that you can dot and dab hardi backers then secure with fixings into the wall when the adhesive has gone off...

If you use cement backer boards or sand and cement render in the bathroom there is no need for tanking imo.

[Dave]

Hardibacker do not recommend D&D'ing there boards..

Oops sorry looks like i've been given and have given some bad advice there!
