Title: Boarding out for plastering
Post by Natedog on Oct 12^th, 2024, 4:21pm

I'm going to be doing a bit of work for my sister, getting her kitchen ready for the new kitchen to go in. The room is brick walls, which were originally plastered with lime plaster, most of which had blown. She has hacked it all off and taken down the old ceiling ready for me to come and attack it.

I'm planning to board it and then skim it, but I've never boarded a brick wall before. What is the best way to go about it? My lazy side wants to use adhesive spray foam, but would it be preferable to batten the walls and screw the board to the battens?

Thanks in advance e ;D

First thing you need to check is the wall construction and potential for damp. Lime plaster is very tolerant of damp, plasterboard isn’t. If there is any doubt then I would use an insulation backed plasterboard as it will stop mild damp penetrating through the board and also increase the insulation in the room. I’ve always used plasterboard adhesive for this, although foam may work you would need to check that the foam and insulation were compatible.
The only time I’ve battened out walls is when they are very much out of plumb, then I’ve used roofing lath and packed out behind it to get the wall level and plumb, but it’s a lot more work and if the walls are reasonably ok I would dot and dab. Just make sure that none of the dab forms a bridge past the insulation!

Cheers dude

I know there is a damp course in the wall, kinda links like old roof felt. I helped my old man put a big extension on the back about 30 years ago. They're also all internal walls and it is all nice and dry.

I don't actually know how straight and plumb the walls are. It does look like it was thrown up, rather than lovingly and carefully built 😆

I'm going to try and get over there next week, so I'll let you know how I get on

There is a YouTube channel called On the trowel and he has a load of content on plastering of all types, well worth a look as he really knows his stuff and is a good communicator.
If you use taper edge boards you could get away without plastering. If you want to do a proper job and plaster the wall look at Speedskims, they are expensive but they can really help you get a professional finish.

I was hoping to get away with tapered edge and then just put some plod over the joints ;D

I'll go look it up now. Thanks dude
