The socket marking tip is pure gold👍 Another bonus to using polyurethane foam for bonding plasterboard is there is no cold bridge spots as there sometimes are with conventional dry wall adhesive. Foam has great insulation qualities
But I was thinking, in 2023 don't they require at least 244 mm of insulation to give you a decent EPC compliance? I have the plasterboard and all, but I am thinking about sandwiching some kingspan in between, will the foam hold to both wall insulation and plasterboard or do I need to screw it in on-top? I didn't want to build a timber frame.
LOVE LOVE LOVE your channel. It helps me to tackle other jobs I have only a little experience with saving me so much money. I love how you explain the procedures without blinding us with science like some others. Plus I love your accent too. Your product placements make me laugh but are useful as if you like the tool/product that's good enough for me.
Sparky here. It was very nice to see you have shown that you isolated and locked off the sockets. Very good video. Will sub to you just for that for that bit alone.
Nice video mate . Your nice and humble not like a lot of tradesmen who do these videos,who seem very cocky and arrogant . But I will stick to board adhesive thanks.
The insulation improvement will be enormous!. A still air gap coupled with the polyurethane foam will be giving a resistance value close to 25mm foam backed plasterboard. It would be interesting to do a controlled test to verify the U value.
That's not how it works, the R value of plasterboard is low and putting some foam in it wont give you an even insulation so you will get cold spots. The best results are if you batten the wall and then put PIR at least 50mm in between, tape the joints and then plasterboard on top with skim or tape and joint.
I've used this stuff several years ago!!! It's ok if you just have a few boards to do! Actually saves time and makes less mess. However I don't think it was intended for bigger jobs..... Thanks for sharing
I agree, I wouldn't say use this to a professional dabber but for a DIYer I think it's easier to use. It's been a few years since I made this video and the walls are all still sound
Nice video and just a tip at 2:03 draw with a pen on the wall on the right side of the board to mark its position and then foam on the wall after moisting it within the penline, then on with the board, lesser foam accidents
I like the bit where he puts the X in the box to make sure he remembers which bit is the waste material lol Good video, this stuff being used does prove the old continuous bead of board adhesive along the top for fire break is complete BS
Do you have to put a vcl if it’s a cavity wall. Thinking of using insulated plasterboard. Also dya think you could use this method on ceilings . Cheers
Great video 👌🏽 Just recently started using foam myself I can’t fault it so far, cleaner, less strain on the body ! Also easier trick I find for the back boxes is to use off cut of plasterboard to scribe around them so leaves a chalk imprint on the back of the board when you tap it !
whats the fire resistance of the foam? with dot and dab the head of the board is filled solid to prevent possible fire from rising behind the board and sub wall. with this I don't think the foam would last long in a fire and may even catch light and increase the fire risk. all the boards would flop off the wall into the middle of the room along with cable sandwiched behind it and make escape a nightmare aswell as any firemen entering being in trouble. I bet it has it uses for hard to get to places but I don't think uts a substitute for traditional dot and dab
Thanks for doing. Was going dot and dab but think I'll try this . Ever used Mega Stik? And which woyld you recommended. Nedd to stick 50mm insulating plaster board to breeze blocks and was going to PVA . Can you also recommended a good foam gun
I have used a similar product to line a steel shed with styrofoam and osb. Very pleased with it. Just wondering in a domestic situation how long would it hold plasterboard if a fire broke out. Maybe a few metal fixings would be good.
@@livingoffgridinscotland thank you, I,m about to fireproof board (and insulate) a garage to hold my office, solar inverters and batteries. Fire was a big thing on my mind, I will screw plenty fixings.
I notice the plasterboard will be sitting a fair way off the brick wall due to conduit, socket etc. Is there any problems aligning the plasterboards with this method or do you just push and eyeball it?
I didn't have much trouble aligning the boards but you could always throw in a few screws if you're having trouble. Thanks for watching and please consider subscribing 👍🏼
I cant help but wonder how the expanding foam doesn't push the board away from the wall. I guess id have to try it and see for myself what happens. One place i absolutely detest dot and dab is in kitchens. It can be a nightmare fixing back wall units. Sometimes, the old fashioned or traditional building methods are much better.
You'd maybe consider the original dot and dab method for a wall with wall units to be fitted and make sure the wall is well dab'd along the fixing line for the wall units. It's very solid once it cures and would be plenty to stop the bounce depending on the thickness. The wall behind is pretty important too and you have to make sure you use longer screws to fix the brackets.
Very impressive. Don't like dot dab as allows moisture potential condensation and mould. Supposed to apply bead all round edges to stop this, as you showed with foam, but rarely done. Easier by far with foam. Have fixed skirting with foam and very handy when needed to take it off later for furniture. Breadknife.
Great tip. You could use two screws mid bottom and mid top as anchor points to grab the plaster board and then just patch the small holes to save you getting foam all over your hands.
Thank you for your clear video, I can use this on my rsj where the builders used dot and dab and timber which then failed as the timber took all the moisture out! Got a more competent builder to re finish the big structural stuff but leaves me to plaster board the rest. I’ve done the framed bits so dot and dab is next!
Why did they dot & dab on timber? I always use screws. Good luck with your boarding and let me know how you get on. Thanks for watching and please check out my other videos and subscribe to help my channel grow 👍🏼
@@spendtimesavemoneydiy you miss understand, screwed on all the framed bits bow it’s time to dot and dab the rest! I do have a steel rsj to fire board so this stuff will work perfectly on that!
I like the idea but one question.....how many sheets will one can of foam do and how many bags of adhesive would it take to do the same number? In other words what's the cost comparison?
Thanks for this, exactly what I needed. Need to plasterboard my garage. Never done any plasterboarding so this was really helpful. What kind of screws will you use if you needed to tighten the board to the wall. I'm guessing you will need wall plugs which will be hard to put in once the boards up. How do you get around pipes that are in the wall?
I have tried both but I prefer dot and dab in long term as the plaster hardens and prevents plasterboard not to warp. Foam is soft and can distort the joints.
I’ve got a basement room on our extension which is slabbed floor and walls seemed damp before all outside was rendered. You think this system you use would be ok now walls have dried out??
Would this foam offer any insulation R factor? I'm trying to figure out the best way to install insulation and drywall to a single depth brick garage conversion so it isn't so hot/cold inside. Thank you!
You have to insulate and add a vapour control barrier. Look at part L of the regs as they have changed recently. Talk to building control aswell because if want to sell in the future it will be a nightmare. This method still needs mechanical fixing.
I've chopped of 1.5 meteres where damp was and will be putting drywall on after damp proofing. What can I use to fill the small horizontal gap between the new drywall and the old existing brickwall.
Nice one. Your videos are always very informative. I’ve used the foam before. I found you don’t have much time to work with it. Need to get it plumb quickly. I was putting insulated plasterboard onto old walls ( plastered and painted ) so this may have reduced my time significantly. Overall though, it’s been done a couple of years now and no issues.
It works great with insulated plasterboard and the extra rigidity of the insulation makes it easier to install than regular plasterboard. Thanks for watching 👍🏼
I have a very uneven wall i need to do this on (plastering on bottom but not on top of wall, also a chimney i removed). would dot & dab be better for such a particular case? because then I can just use bigger dabs in order to level things out. that seems difficult with this adhesive?
Great video! Very informative and gives me the confidence to get on and re board my son’s room! One question, I see that the socket on the wall has been chased in slightly but it looks like another hasn’t. Is there a ‘best practice for how much a back box should protrude from the wall prior to boarding in this manner? Also, what’s the finished gap between the brick/block and the board? Many thanks!
The reason I make videos is exactly what you said. To give others the information and confidence to tackle jobs themselves and to pass on some useful tips too. So I'm glad you are giving it a go. Some of my backboxes were deeper than others so that's why some are chased in. A 35mm box will probably end up flush to the board without chasing it in but it will depend on how much foam is used and how plumb the walls are.

I've never used foam to dot and dab but I'm on a job now where I've got no time or adhesive, just watched this after a quick search, using the exact same foam and it won't even stick to the substrate. I'll stick to drywall adhesive. Always thought it was a bad idea tbh. I'm a fully qualified plasterer as we before anyone chrips up
That air gap between board and block work will suck in warm air from the room causing mold to grow , and how is that airtight with no sand plaster mix on the block work ?
Will this stick to a painted brick wall or would the wall need prepping got some boards in the hall way ready for the spare room debating the best and easiest way to do it if this foam sticks to paint then I think this might be my easiest option I bought some plasterboard adhesive but my uncle told me I've got the wrong 1 I need dry wall adhesive I've helped plasterers in the past but they have always screwed plaster boards to battens
How far of a gap can you leave between the brick and the drywall? I need to add some plasterboard to repace a damaged but but the gap is around 1 inch. would that be ok? Cheers. Great tutorial by the way matey.
I have done something similar when I took out a corner chimney breast. It worked fine but there was a section that was a bit flexible so I drilled a 10mm hole, squirted in more foam and it was solid. It's probably just a bit more difficult to hold in place whilst it sets when the foam is thicker. Thanks for watching and don't forget to like and subscribe to help me out 👍🏼
I leave the gap to stop any moisture being absorbed from the floor into the plasterboard. Then I hide the gap with skirting boards. Thanks for watching and don't forget to like and subscribe to help me out 👍🏼
I like the socket marking idea..Is this going to be a habitable space..? Does it need a vapour barrier or is that on the existing wall..part L building regs?
hi great vid i watched this before and during putting up my boards - worked great! thank you :). or those sockets do the cables need to be chased in to get good contact with the wall? Also any advice on keeping the boards pushed to the wall while it goes hard. I had to stand holding them for 10 mins.
Chasing the cables would be better but very time consuming. You can throw a few screws into the wall to save you holding it. Thanks for watching and don't forget to like and subscribe to help me out 👍🏼
@spendtimesavemoneydiy - avoiding those cables as you throw the screws in :-). I like the idea of the foam as it avoids finding pipes and wires. I know one can use a detector but I wish all homes came with a 3d plan of pipes etc.
Not tried that brand. I tried another brand for insulated plasterboard but found it cures too quick for you to work the boards. Does that stuff allow more time ?
A tip for getting dried foam off your hands. Rub vaseline into your hands thoroughly before bed time and it will literally drop off the following morning.
Push it back to the wall with a straight edge, any belly in area the foam will squash really easy and the board will then belly in so use that straight edge. A couple of straight long timbers held vertical against it with a couple of timber prop holding them in place for initial cure period, say 5- 10 mins. Only put some extra fixings in after fully cured or it will also pull the board in.
How solid do the walls feel after you’ve used this? I’d be worried they feel a bit flimsy. I’m a clumsy oaf and reckon my elbow with go through easy with the foam 😆 any thoughts?
The walls need to be quite flat/straight to use foam. I've struggled with 1920's walls where they can be up 25mm out. In those days great dollops of plaster sorted everything out. If using on aircrete blocks you can drive long plasterboard screws straight in, to pull it all level/plumb..or hold it with a straight edge for 10 mins+!
I've used it on really bad walls. It is difficult and I used a lot of foam. A good tip is if you have a little movement in the board after it's cured them I drill a 10mm hole and fill with foam and it firms up great 👍🏼
Thank you. Full of info and the socket marking a real spot on idea.
Hardwall and bonding on that surface mate, followed by a tight skim. unbeatable.
Really good video one question can you use sticky foam on insulated plaster board please
I use the Soudal plasterboard adhesive. Amazing stuff. Would never dot ‘n dab.

@@thewizardsofthezoo5376 I just had building regs people round in mid 2023 and they required 100mm foam board, not 200plus
You shouldn’t get cold bridging from an internal skin as there’s insulation in the cavity.
So what do you do when you have to adjust the board? like having to pad it out a bit more.

You could use a peace of wood at an angle as a prop maybe?
@spendtimesavemoneydiy - avoiding those cables as you throw the screws in :-). I like the idea of the foam as it avoids finding pipes and wires. I know one can use a detector but I wish all homes came with a 3d plan of pipes etc.
What screws would you put in?
I just used plaster board screws with red wall plugs.

@@spendtimesavemoneydiy done:. Really appreciate your reply.
Not tried that brand. I tried another brand for insulated plasterboard but found it cures too quick for you to work the boards. Does that stuff allow more time ?
There is a little bit of workable time but not much. I find preparation is key. If I prep it right I don't have to mess about too much 👍🏼
I would watch where you use this No Nonsense Sticky foam as it is not fire rated?
Awesome video. I'll be doing this soon
Don't lol
@@liquidsnake6879 that's helpful
Yes Andy Sugdan. Hope your doing well. Can’t see that working as d&d though
I just love the accent 😊
Thanks 😊
A tip for getting dried foam off your hands. Rub vaseline into your hands thoroughly before bed time and it will literally drop off the following morning.
Excellent video mate. Super clear and many thanks for the impression amd marking top tip. Buying this product tomorrow. Ta la.
You're welcome, let me know how you get on and if my video helped you much 👍🏼
Push it back to the wall with a straight edge, any belly in area the foam will squash really easy and the board will then belly in so use that straight edge. A couple of straight long timbers held vertical against it with a couple of timber prop holding them in place for initial cure period, say 5- 10 mins. Only put some extra fixings in after fully cured or it will also pull the board in.
How solid do the walls feel after you’ve used this? I’d be worried they feel a bit flimsy. I’m a clumsy oaf and reckon my elbow with go through easy with the foam 😆 any thoughts?
What is the burn time of this stuff? I thought building regs require a fire barrier at the top of the board?
Avoid using this at all costs mate
Its ok if the walls are flat but what about when you need 2 inch of board adhesive In places a d its tight to walls in other places
Very good video!
Glad you enjoyed it.

The walls need to be quite flat/straight to use foam.
I've struggled with 1920's walls where they can be up 25mm out. In those days great dollops of plaster sorted everything out.
If using on aircrete blocks you can drive long plasterboard screws straight in, to pull it all level/plumb..or hold it with a straight edge for 10 mins+!
I've used it on really bad walls. It is difficult and I used a lot of foam. A good tip is if you have a little movement in the board after it's cured them I drill a 10mm hole and fill with foam and it firms up great 👍🏼
Thanks for this. Struggling with uneven walls myself. Maybe make another video with older, uneven walls?
