When you have deep and awkward gaps to fill it is difficult to do a good job with conventional fillers. Watch this short video to show you how to make the job easier.
Or cut a block of wood to fit the hole, stick it in with some no more nails adhesive then fill or plaster over to finish! This way you don't have to wait hours for the foam to set.
@@scrimperuk I have just filled a gaping hole where the extractor was and it took all of ten minutes. I am like you, got all sorts of bits and bobs saved in the shed for these kinds of jobs.
Great video - very clear. Thank you. I do have one question though. I have a similar sized hole to fill in my daughter's bedroom. However, the hole goes back about 12-15 inches into an old, disused chimney (a jackdaw had come down the chimney and the only way to get it out was to remove the vent and then make the hole a bit bigger!). Will your method work in such circumstances - does the foam just sit in the hole or does the foam in your video go back up against a 'back' to your hole? Hope this makes sense! Thank you.
PolycellUK - I realise this is a how to guide aimed at selling your products but the foam is excessive! Far better things that could be used to bulk fill that hole. A block of wood, ply etc. and a little piece of plasterboard fastened or fixed with grab-adhesive would offer a better substrate for the filler and would be more secure. Advice people: never watch a "how to" video produced by a manufacturer, find a tradesman who makes videos and follow those.
Guys after cutting and sanding, paint some PVA glue to the service, makes life so much easier They don't mention it because they don't make glue I'm guessing
Can you leave the tin after the first use. Or is it a crack open and use it up or throw away. Like a fool I got the biggest tin and its not that cheap really at £12 a go. Should have got the £7 can now. But im really glad polycell put these videos out great company. Thank you.
Will this work to seal off an old no longer used floor HVAC vent that I cannot get into to use fiberboard cut pieces and caulk to seal off? There is no way I can get into the vent to clean it before applying this foam sealer. It is a ten inch by two inch rectangle than I cannot get my arm into down to the bottom of the 24 inch shaft bottom where the actual ductwork ties to the vent well.
How about when the screw on applicator gets clogged after the first use? rendering the contents of the can useless after one use??? it just dries in the applicator nozzle blocking any more foam from getting through ??
I need to fill a hole about 4 inches x 1 inch where a double plug socket was moved up after being put in the wrong place. Naturally there are live wires behind the socket, is it still safe to use these liquid based products to fill the hole.
Switch off all your sockets at the mains before you do any work (if any doubt switch everything off) then make sure the wires in the old socket hole are properly connected red to red/ black to black/ plain copper to plain copper into a 30 amp connector block and use earth sleeve on the plain copper. then cover the connector block with some insulating tape. Now cut the bottom off an empty plastic milk bottle and shape it to just cover the wires. Now you can dampen the hole and start to apply filler from the edges first to hold the plastic in place then when the filler is dry you can apply more bit by bit until you get level. You can switch the electric back on as soon as the first filler is in place.
There is a large crack on the bedroom wall and i was wanting help in what product to use. I can't afford a plasterer. PLEASE advice me on what to use. THANK YOU
So he knows how much it will expand ..but filled the entire hole with unexpanded materials ..Cleary he is extremely smart . He wasted more than 50% of the material..
Awful. Simply awful. What I would do is prepare a piece of drywall a bit bigger than the hole, put grab adhesive all the way round it, insert the piece into the hole and pull it forward with a preattached piece of string so that it covers the hole. Now you're left with a gap thick enough to apply undercoat plaster and 2 coats of skim. But tbh I would just use polyfiller and sand.
fro0tyl0opy87 You have a solid wall (there is no plasterboard there if that's what you think it is). You cannot glue the edges & pull a bit of plasterboard into place then expect to fill over it with plaster. The plasterboard will fall back into the empty void the moment any pressure touches it. To fill a solid wall, you need to fill the empty hollow. You could use cement or even bung it full of plaster. However most people won't have the experience or will to go through all the hassle. Expanding foam is cheap & most of all - it's an easy quick fix that anybody can do. Once dry, it can be cut level with the wall & then skimmed over to make it level.
James McC To be honest with you, I don't know what the hell I was thinking of saying that because it's a solid wall so I don't know what made me think it was plasterboard he was filling! Yeah as you said, filling with plaster will work fine and is easy enough. Then finish with polyfilla and sand for a smooth finish.
+Rebecca Pucci yes. if you want to block out mice stuff the hole with steel wool first, then fill it with any foam.wouldn't hurt to use caulk to secure it.
Mrs. Pucci unfortunately yes mice will chew through the foam but the plaster/puddy should keep them out if applied thick enough. What I recommend is putting dry wall mesh tape over the foam after its been sanded then apply the plaster.
I realize the chap's trying to sell some products here, but I don't see the need to spew more plastic into our environment-isn't there enough in it already? (It seems like he wastes as much of it as he uses, too, due to the expansion.) Personally, I use this simple method to fix these types of holes: 1. Cut a piece of drywall slightly smaller than the hole. 2. Cut two pieces of scrap 1/4" wood about 1/3 as wide as, and slightly taller than, the hole. 3. Spread some expanding glue on the wall's inside surface, about 1/2" all around the hole. (Gorilla Glue is good for this; before you apply it, use a wet paper towel to moisten the area to activate the glue.) 4. Insert one piece of wood through the hole and pull it back against the glued area so it covers the left 1/4 of the hole. Use two small spring clamps (the type you can get at the dollar store) to clamp it in place behind the top and bottom of the hole. Do the same on the right with the other piece of wood. 5. When the glue has dried, apply glue to the exposed parts of the wood (wetting them first if using GG), then press the drywall piece into place against them. 6. I now place a long piece of wood (e.g. a 2x4) against the fill piece to hold it while the glue dries. You may prefer using painter's tape, or some short drywall screws. 7. When that's dry and firm, fill the gaps with drywall filler or PolyFiller, let it dry, then sand and paint.
Can anyone help me please? I'm using multi purpose polyfilla,covering some median large holes,it says to film in stages/layers I have the first layer dried,here's the question, Do I need to wet the polyfilla to add another layer? Or just as another layer dry onto the polyfilla?
Expensive and crap approach best to just fill it with undercoat Plaster and build it up then when roughly smooth leave about 5 mm to put on a layer of pva once dried then use finishing Plaster with trowel and make sure the finish is watery for a,smooth finish spray with water If still rough and smooth till it blends in with the rest if the wall.
Love the stream of comments - esp the one about expecting the porn site - filling deep and awkward gaps - haha!! HOWEVER ..... i have stone cottage wall. The curtain rod holding has ripped out and left a hole in the wall. If i just use polyfilla will it be strong enough to hold the curtain rod fitting again afterwards??? Serious answers please or i will end up ;putting this wretched foam in it!!! Thank you lovely people :)
Thomas Bishop How the hell can you replace the 'drywall' when there is no 'drywall' there to replace. It's a solid wall that's been hollowed out to fit in a socket.
The foam expands two and a half times so do a little at a time, as he completely fills the hole til it is overflowing.
haha yeh made me laugh too.
Wonderful tutorial. Needed to find a way to fix holes in the walls when redecorating and this came in very useful.
It has just helped me too
Pro Tip, if you sand the poly-fill lightly and apply additional coats you can create a smoother finish :)
pro tip use plaster and sand it.
He is a pollyfilla expert, he knows what he is doing.
Omg it literally worked on my 100 year old plaster and lath walls. Wow! Thank you so much
he shook it 21 times! :-o
Bradley Moule you have got a problem, if your comment is that he shook it 21 times instead of 20. BTW, I have the same problem! 😂
IKR
I don't think he will face any major delay at the pearly gates.
😯😯😯😯🤣🤣🤣
😁😁
rather than replacing my front door with a new one can i just remove the door and fill the gap with this foam?
+PaperBag sure u can, u will just need to cut from both sides.
Too funny
Hahahahaha
Damn good security you'll have. No chance for burglars to get in.
A bit over the top with the PPE. All he's missing is a radiation suit.
Damn it! I have everything except the household water....I'm screwed ;-(
Remember guys to always wash your knife in warm soapy water
Or cut a block of wood to fit the hole, stick it in with some no more nails adhesive then fill or plaster over to finish! This way you don't have to wait hours for the foam to set.
Would there be a risk that the timber will expand and contract over time, causing the plaster skin to fracture and weaken?
plaster doesn't stick to wood that's why you have atrave to cove the cracks. just hardwal the hole then easy fill it, done.
I am going to use polystyrene which came with the t.v packaging to fill the hole and then filler over the top.
@@englishrose5483 That is what I do nowadays, I always keep some in my 'stock' for such a purpose, it works fine.
@@scrimperuk I have just filled a gaping hole where the extractor was and it took all of ten minutes. I am like you, got all sorts of bits and bobs saved in the shed for these kinds of jobs.
That will always be a soft spot in the wall, unfit to hold a screw.
very well explained thank you!

•wear protective equipment before using
•use in a well ventilated room or area and always remember *THE FOAM WILL EXPAND*
yes expanding foam tends to expand
That must be some magical filler, it dries already sanded, wow!
Many thanks will bee really helpful for my work to come
"Shouldn't even have to sand it afterwards"
HAHAHAHAHHAHAHAHAAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHA
I know .
Nightmare
😬😬😬
That's where I've been going wrong . I've only been shaking it 19 times 🤔
Plus the 12 + hours waiting for foam to dry. Nope, use a piece of Gyprock instead
Yup, California patch
Brilliant video. Nice, clear, and short! Love to watch it!
You said difficult holes. This is possibly the easiest hole position I’ve ever seen
You could have just stuffed it with newspaper
Just saved me money thanks, was about to get a plaster 👍🏻
CHAMPION !Thank You !
Great info, tyfs!
You need to push and compress the phone foam back to leave at least a 5mm of a recess, then apply your filler

what foam did you use??
Great how to video
The problem with the foam is, you can not keep the rest for another use, maybe in the next month.
UA-cam has posts for reusing. Do search.
Step 5: toss the remaining 95% of the foam, in its can, into the bin as the nozzle can only be used once.
Put it in a ziplock bag you might get to use it again depending how long it sits
Just unscrew it and buy a new nozzle for the next time 🤔
Only use it when you have a lot of holes to fill in as you only get one days use from it.
Thanks. Well done.
Thank you great video! 👍🏼
Can this be used where there are pipes and cables , will it effect the pipes in any negative way ?
Hi there, can I use this for filling in a massive gap between the window frame and wall?
How about exterior walls around gaps around newly installed doors? Is there an exterior filler??
So pleased i watched this otherwise i would not of wet the area. Thanks
Can this type of product be used to fill gaps in an exterior wood fence?
I thought this was going to tell me how to fill in awkward gaps in a conversation. Woulda been better. WHY WAS THIS SUGGESTED FOR ME?!?
orange juice 😂😂😂🤣🤣🤣
Cracks appearing in 3, 2, 1, NOW!
Can I use multi purpose polyfilla in window frames and window to seal , so cold air won’t come in?
Moisten before applying foam. UA-cam has posts for reusing foam in can. Do search reuse.
Also please tell what can be used to fill a hole meant for AC provisioning. All rain water seeps in through that hole. Waiting for your reply. Thanks
Can you leave the tin after the first use. Or is it a crack open and use it up or throw away. Like a fool I got the biggest tin and its not that cheap really at £12 a go. Should have got the £7 can now. But im really glad polycell put these videos out great company. Thank you.

That’s about 15 dollars to fill up a hole. Can I use it to fill up a gap in my teeth?

Throw it on the bonfire Nov 5th makes for a good firework it's like the garden is covered in growing snow.
clean the nozzle with acetone
Can you put filler on any type of expanding foam, or must it be this brand? Thanks!
any brand's fine
They are all pretty much the same.
Goddammit i shook it 19 times.. i may as well sell up
xamurai00 made me laugh 😂

Can you use the Polyfilla to fill cracks in a car's dash pad? I'd like to fix the foam first before wrapping it with new vinyl.

Congratulations you've just spent £15 on expanding foam that will cure in the nozzle and never work again.
I had a gas fire removed but the gas line is capped off in the wall along with a large hole, would this do the job?

The gap i need to fill is in the bathroom - to the side of the shower, how water resistant is it?
Fill the whole thing with polyfilla!
I now feel like a cream bun :-P - thanks, yummy!
Says to shake twenty times but you shook it 21 times. Will it still work? 🥺
Can anyone help me please? I'm using multi purpose polyfilla,covering some median large holes,it says to film in stages/layers I have the first layer dried,here's the question, Do I need to wet the polyfilla to add another layer? Or just as another layer dry onto the polyfilla?
Just key it first and then damp with spray to stop it stealing all the moisture from the new layer.
He shook the can 21 times 😏
+snowball1988 exactly
you can't trust him.
snowball1988 u been counting lol
Can I use this to close air vents
What if you need to drill in that space again, what’s best to use to make it go hard?
Polyfilla
Is that toxic?
I bought the polycell one fill it is not setting whats wrong with it
Expensive and crap approach best to just fill it with undercoat Plaster and build it up then when roughly smooth leave about 5 mm to put on a layer of pva once dried then use finishing Plaster with trowel and make sure the finish is watery for a,smooth finish spray with water If still rough and smooth till it blends in with the rest if the wall.
From the title of this video I thought I was going to get tips in how to avoid silence in conversation. Misleading.
dont do this..... do it properly with a piece of drywall with a back mounted stud. use some joint compound, sand, texture, paint.
Do you think this would work on a ceiling?
Nurbibi Faruk yes worked for me when I filled two holes from garage door track studs I removed from the ceiling.
would have been easier just to dot some plasterboard and get it filled...
Can you fill bedroom vents with this foam?
No!!!
Will this work on exterior? Like some gaps between raptors?
Yes it will.
1:58 You might want to mute the video for a few seconds.
Isnt This The Guy Of The British Gas Advert ?
thanx
@Tony DC Thanks for the advice. Actually not the ideal way in which some extravagant
@Tony DC Actually these methods are better and more practical. Thank you so much God saved you
Question...can you tile over it?
maybe applying sand+cement+water instead of foam makes the job easier..imho
Can this foam support screws going in to hold up a strike plate for a light weight interior door?
08swede it will only support bolts and heavy duty fixtures.
I don't think it is strong enough to support much of anything.
It did not work. I only shook can 19 times.
What about a mask, mate? Breathing sanded urethane is really not a good idea at all.
1:15 then proceeds to look straight at the can while shaking🤣
Why should you "shake away from your face anyway? 😉
Holes are never that smooth lol
i only have a new scraper awwww
Sea Winds and I only have an old one so we’re both screwed. Unless we team up! Muhahahahaha
Them foam cans are a nightmare. The foam keeps coming out the can even when your nor pressing the nozzle
Don't have to sand it after filling it? Yeah right, not going to notice it after painting? Bullshit
I got 2 big fuck off gaps in my teeth.. you think this would work?
Wow, just wow *he says in a sarcastic way*
Say it loud - When you fill leave it proud!
That is crap ,Need to re-insulate the whole then put a drywall patch and tape it and float it out right then sand and paint
This is fucking awful. I'm a plasterer and this is just absolutely shocking
1:52 it got pregnant
Love the stream of comments - esp the one about expecting the porn site - filling deep and awkward gaps - haha!!
HOWEVER ..... i have stone cottage wall. The curtain rod holding has ripped out and left a hole in the wall. If i just use polyfilla will it be strong enough to hold the curtain rod fitting again afterwards??? Serious answers please or i will end up ;putting this wretched foam in it!!! Thank you lovely people :)
Christine Mora no do not use filler, the curtain rail will rip off in time
Hahahah what a joke. Do it the real way and put backing in and replace the drywall. Then tape it. And 2 coats of plaster
Thomas Bishop How the hell can you replace the 'drywall' when there is no 'drywall' there to replace. It's a solid wall that's been hollowed out to fit in a socket.
Typical US cardboard crap house.
