Plasterboarding brick walls

[Deluks]

If you've not done it before, go with battens. The other options require you to act before stuff 'goes off', with battens you can take your time and get it right, and easily backtrack if need be.

With foam or d&d you are also relying on the adhesion of the paint to the brick to hold everything up, it will most likely be ok but paint's a funny thing.

When I used a foam gun I only cleaned when storing for a while , otherwise I just added another can , up to around 20 without any problem .
Lighter fuel is a cheap way to clean wet foam off your hands .

I used my foam gun for the first time in about 3 months. I leave the foam canister connected until I need to replace it. This gun is only 1.5 years old, it has had about 6 canisters thus far. To date, I have only used the gun cleaner to clean the tip.

I would never want to go back to using non-gun versions of foam. The ability to control the rate of flow was worth the £30 I paid for the gun.

Out of interest, which foam gun do you have?

Also probably worth pointing out to Johnw2, that it's a good idea to foam around the perimeter of the boards even if using battens, to restrict the movement of air.

Thanks. I've done battens and plaster-based D&D (albeit relatively small walls), but I've never used foam

Good point.

Yes, that was one of my concerns. As I've said there are some 130 years worth of coats of paint. The most recent ones seem to be emulsion or masonry paint, but I imagine that there is probably whitewash, or worse, under the more recent layers!

Thanks. If I use battens, including horizontally if/where there were horizonal joints between boards, there wouldn't really be any 'exposed perimeter' of boards, so where could/would I put foam?

I presume that I wouldn't need much in the way of battens - would, say, something like 25mm x 38mm be adequate?

 

[Deluks]

No, if you close off the edges with wood then foam won't be necessary.
25x38 is spot on. Get treated battens.

All as I thought/hoped. Very many thanks!

It has teflon where required, eg the pin and base.

A few months prior to buying that, I had purchased a £12 gun from Amazon. It was useable but could not be serviced. I had to bin it after about 2 months.

My current gun, as I said, I will leave it for ages. From time to time, I might need to use a knife to break the seal between the nozzle and the pin.

The gun was also supplied with two straws and two conical nozzles. The conical nozzles taper down to about 3mm.

I'm hoping to get the job done soon (have gathered most of the required materials), but just one last question ...

As I've said, I have limited experience of boarding walls. When I've done it in the past I've used 'anglebead' for the external corners, but never have been quite sure what I should do with the internal corners - so I have usually just taped them. Is that OK, or is there something else I should be doing?

That’s fine
