How to Fix Plasterboard with Expanding Foam Adhesive

How I fixed the plasterboard in my kitchen using expanding foam adhesive. In today's video I run through the advantages and disadvantages of using expanding foam adhesive to fix plasterboard to walls and explain why it's so much better than using driwall adhesive.

I'm converted. I like this much better than leaving wet adhesive to dry out behind the drywall. Thanks for video Charlie 😉 👍

Great video Charlie - really useful stuff. One thing I like about your channel is that you post videos when you have something useful to say, not because you always post a video every Monday at 6pm whether you have anything worthwhile to say or not - just to make money. Well done Charlie - keep up the good work!

[pauldowie]

I love the way you keep your vids really clear, stay on topic and get your message across. Keep them coming Charlie, you're a star

wow that is by far the best vid I've seen on expanding foam adhesive, you covered everything and more, super thorough, great content as usual by your self, this is going to help me enormously on my renovation, so thank you very much

I have another use for Soudal Adhesive Foam which you may not be aware of! When I installed chipboard flooring, 2400mm by 600mm sheets, I sprayed the foam on top of the joists. The joists are original, probably a hundred years old, a bit beaten up! I also used the foam in the tongue and groove of the chipboard flooring. I laid the chipboard on top of the expanding foam, which filled any gaps and also stuck the boards to the joists. The floor is now like a concrete floor to walk on, there is never a creek or movement in the floor. It is fantastic!!

I used the Soudal Adhesive Foam to install 4” (100mm) Kingspan directly to the walls, then faced that off with plasterboards. I used the plastic dry lining double electric wall boxes, dug out the kingspan foam to make enough room and used the 75mm foil tape to damp proof it. Stuck it in with the foam, beautiful job!

I could not get anyone to approve the design of sticking the 100mm kingspan directly to the wall and then sticking the plasterboard to the kingspan. “They all” said I should use the tried and tested method of creating a stud wall.

Each kingspan sheet is also secured with mechanical fixings for fire safety...

In one roof I used 4" kingspan between the joists. You must not push the kingspan against the felt/tiles, you must leave a couple of inches gap for ventilation between the kingspan and the tiles. The trick here is to cut up scrap pieces of kingspan, and then use the Soudal Adhesive Foam to stick these spacers to the joists. It works, because there's hardly any weight to the kingspan foam spacer, it will stick in place without falling off (usually) ....

I installed several door frames, I used a combination of wood spacers, wedges, and soudal adhesive foam. Now here's a good tip for you. Use plenty of foam, and as it goes off it expands like a sponge cake rising in your wifes oven. Leave it until it is starting to Harden. While it's still slightly tacky and not completely hard, tap it in gently with the edge of a scrap piece of plasterboard. This is important because the edge of the plasterboard is just chalk and it will not stick to the foam! You compress It, and it makes a lovely surface of the foam, and the most important thing? What you are doing is you are compressing the foam together and you form a solid sheet of very hard stiff plastic out of the foam. This sheet of plastic will make your door frame absolutely solid and immovable....

There's another use which I haven't used myself but I saw a YouTube video of a guy laying a self-leveling floor. At the boundaries he ran a bead of foam along to stop the liquid from travelling where he didn't want it to go. I thought it was a brilliant idea!

Just about to plasterboard my son's bedroom, thank god I watched your video before buying materials great tips and advice as usual 👍🏻👍🏻

[ridgmont]

4:14 - having “adequate wood” at your age Charlie is something to aspire to!

[martinrothwell]

You make it look so easy! - i have never failed to learn something when watching your videos! :-) thanks for sharing your knowledge, (and owning up when something didnt go right!)

[antoinec]

Good advice. Did all my bathrooms plasterboards and Kerdi boards with Screwfix no nonsense foam. I wet both sides and waited 10 min so the foam was almost cured. I also put schluter anchors on the walls I was tiling after. This is so much better than drywall adhesive. Great video with a lot of good tips!

[shakman]

Brilliant. I've been using plasterboard foam for years and swear by it. It sticks to anything too. So excellent for over boarding a room and improving insulation.

[NikNakGB]

Great video Charlie. Just finished a similar job using k18 plasterboard I got from one of your other vids.
I was a little uneasy using foam on it's own when I discovered Damp Sam uses Drygrip Adhesive from Dryzone in addition.
It's a little expensive but gives that feeling of working with drywall adhesive without any moisture or cold bridging & the added security of not just relying on foam.
Another good tip I got elsewhere is using tile backer board as it has excellent moisture & thermal properties, great to have between your electrical back boxes & the wall, also excellent to use on your reveals.

[flips]

Excellent advice! Thank you for sharing your knowledge. 👍

[PropertyAtAuction]

Just been fixing insulated plasterboard with adhesive foam, it's great!

[kletops]

So many useful tips,
"Buy a non stick gun" I had no idea one existed.
Loved the testing with and without moisture,

[MrToast-hjkp]

Thanks a lot for showing you can use spray foam for plasterboard. I have been refitting a downstairs loo in our old house. It turned into a bit of a mare with all joists rotten and needing replacing. The boss joint had a crack so that needed replacing. Anyway had a wall I needed to plasterboard over only a couple of sheets. This advice really helped. As only a small job so went with Soudal which came with it's own applicator. Also shop had it on offer. Did the job brilliantly with the help of your tips. PVA'd the wall first with two coats. Mind really messy stuff. Went every where ! Walls solid next day.

I've never seen board adhered directly to the steels. I have always used a timber substructure around the steel and then attached plasterboard to that. I do like the foam adhesive and glad you got on with it. 👍👍

[averyboringusername]

Could you provide some advice relating to fire integrity? I thought with dot and dab plaster adhesive you were advised to do continuous runs at the edges of the room to stop fire travelling up behind the plasterboard. Is it advisable to use intumescent adhesive foam for edges?

[nickskinner]

Absolute respect for all you video's. So many great tips and advice...gives me more confidence to use new methods and tools

[latinfm]

What bloody good timing Charlie👍🏼 I’m building a fitted wardrobe using an Ikea PAX cupboard and it’s going against an external cavity wall that I’m not 100% confident on it’s insulation performance so to ensure I don’t have any damp issues behind the new cupboard I’m installing some insulated plasterboard, which I was going to buy from SWIP after your recommendations ( technical guy Ian is a very good bloke!) but they wanted more for delivery than the materials cost so have gone elsewhere. I was going to use plasterboard adhesive but will keep my fingers crossed and use the foam format 👍🏼

[Adamyoutubetest]

Great video, I used no more nails when I plaster boarded a few walls which worked really well too as it sticks so quickly
