Ok great - so it sounds like - dot and dab ok for internal solid walls / cavity thermalite walls, BUT foam or battens preferable - foam and insulated plasterboard OR battens, PIR, and plasterboard for external solid walls When do you need to use the foil backed board, out of interest? And are...

Thanks for this all. Three more questions then: 1. Can foam adhesive expand enough to get round very uneven old walls? I understand dot and dab can go 25mm thick, which is what we're dealing with in some places 2. Do I need insulated / foil backed plasterboard on the uninsulated external...

Hi - I'd like to ask a bit of advice about hanging plasterboard, as I've heard conflicting things. I'm renovating a house that's about 130 years old. I've built an extension and taken down and added some internal walls. For the new stud walls I've sheathed them in OSB withacoustic insulation...

Thank you!

Already got the electrics and plumbing sorted and there's no need to level it. The only thing I'm worried about is the plaster failing over time and pushing down on the new boards.

I need to overboard a ceiling for plasterboard. The existing ceiling is old lath and plaster and pretty cracked. Do I need to get the old ceiling down first or can I just find the joists and screw the new boards to them over the top? Thanks!

Yup, got it out ok. The pipe's a peculiar dimension -- 110 across, 130 down, which I guess is because it's cut at an angle. The 4" extension connector ought to do it.

Thanks! So cut out the old connector, and the new one should fit in ok without all the sealant?

Hi -- I'm replacing a manky old toilet and the new one has a pan waste which is slightly lower -- bit less than 10mm, by my estimate. There's an old cast iron pipe that comes in through the wall; whoever installed it put an offset connector in to raise it up to the level of the old toilet. It...

Just saw someone on another forum suggest dot and dabbing tile adhesive to the back in the void sections and then drilling through with mechanical fixings when dry. I'll be using tile adhesive on the boards anyway to fix them to the walls, so that would cut out a step and so be a lot faster, is...

Love it, thanks mate

I think I posted this in the wrong forum initially, sorry! I need to put some wedi boards on the wall for tiling. When the old tiles came off they left a recess behind them -- there's old plaster, then two feet of bare concrete blocks that the tiles were stuck to, then old plaster again below...

I need to put some wedi boards on the wall for tiling. When the old tiles came off they left a recess behind them -- there's old plaster, then two feet of bare concrete blocks that the tiles were stuck to, then old plaster again below where they were. The gap's a centimeter or two, larger in...

Fair enough! Got really rattled when my first try at attaching it failed. Simplest answer is I didn't tighten it properly -- I was just casting about for other reasons cos I'm desperate for it not to fail again.

It's still holding ... Here's a picture of another offcut. As you can see it's pretty thick and sort of wedge-shaped.. The other one had a more pronounced wedge and completely flat back end.
