You know what I love? Plasterers who are convinced that a "magic mix" of SBR and PVA 50/50 is the way to go. I've never heard such shit in all my life 🤦😂
Moved over to sbr about 15 to 20 years ago . Just got fed up with mixed results from kids glue that sticks lollipops together . We had always used sbr in damp environments and S&C work just moved it over to general plastering we wasn't sure at that time but the results proved it far more reliable . Totally agree with this top advice 👍🏻
If you add it to concrete it increases the compressive strength. Used in many products both as a primer and within the product itself. Decorative concrete resurfacing. Roof paints and membranes, tiling adhesives, elastomeric membranes, strutural grouts, tile grouting etc. It can be added to any sand/cement based products. Probably not great where the substrate needs to breath such as lime based mortars/plaster etc?
How long have you been plastering for mate? You needed a you tube video to learn about the superior properties of SBR compared to PVA, did the guy you served your time under not teach you these things?
I always used pva when plastering . 20% pva 80% water never had a problem and anything that’s high suction I just apply a bit more to that area .I only use SBR in render. I’m not saying it’s better or worse just how I was taught to do it .
Ive always used sbr for area that may get moist and outside. Thinking about it now im not sure why i use pva, ive got some hardwall to skim over might try sbr
Lost faith now bro if doing artex ceiling its better using pva with a dash of sbr then you wont be waiting for a set the whole point of a set is you want it to dry that means you can get on the next set .your strokes should be going way past your shoulder too .never good to kill the suction completely😢
Hi m8 been using sbr neat few months now from watching one of your videos with no problems but last week I skimmed a living room out and neat sbr it day before and as putting first coat on it was dragging and blebbing and drying out to a degree and couldn’t even flatten it properly and second coat not much better but beat it with bit of sweat, bout 25m then did the walls which were the usual flaky paint after wallpaper stripped which not normally a problem in past but they sort of reacted to and made it bloody hard work, have you ever come across this, wondering if sbr bad batch or got too hot in van, I don’t know but it’s put me off?
I’m a plumber so I haven’t much clue on plastering. I wants my hall landing and stairs plastering. But the couple of pals I know that plaster said because of the walls are silk paint it’s going to be a nightmare and I’ll need gritty pva stuff, So SBR will be okay?
Add the right gauge of water to activate, the original sbr back in the late 80's was poured out white from the tub then when water added, turned a bluey colour It's all I use
@@Onthetrowel cheers pal, thanks very much for the direct reply, much appreciated… i’ll give it a whirl, the wife just had me knock a wall down, and even as an amateur plasterer PVA never felt right.
Can you do a video on how much to put on Kirk I think I’m putting too much on the ceiling I did yesterday still wasn’t dry after a hour or so but the walls was made no sense ??
This video reminds me of a tune by "NEW KIDS ON THE BLOCK" in the Good old 90's😂..... "Step.1 we can have lots of fun. Step.2 There's so much we can do.😅 Step.3 Its just You & Me. Step.4 I can give you more. Step.5 Don't you know that the time has arrived.😂😂😂😂
Pva is water based and re-emulsifys when it gets wet. You can leave it to completely dry and then when you put wet plaster on it it will go tacky again pal.
You don't need to sbr the bricks before using adhesive but damping the walk down helps if it's dusty. You can skim straight over moisture board but if you read the product data sheet it states that you should use thistle bond it although nobody ever does. (British gypsum boards)
If your worried about back grounds, do a little test dab and come back to it 24 hrs later. You can dab to ALMOST anything. But painted walls. , a wise man once said .😉
@@Onthetrowel yeah that's what I always do neat 1 coat.iv not had anybody phone to say it's fell on floor yet 😂 keep them videos coming buddy best plasterer /RUclipsr out there for sure
@Onthetrowel you I definitely wouldn't sbr painted walls or artex and leave sbr dry , you are essentially just sealing the background you have to hit it tacky in order to stick if theres no key , that's why I always use pregrit
@@Onthetrowel it is extortionate but so’s the finish near £20 a bag after tax. But I’ve had 2 ceilings come down with pva and sbr. Don’t know why done everything right not cement in the finish or bonding. The other ceilings stayed on. So I use thistle bond on every ceiling now
When they came down... did your plaster come away from the primer or did the plaster stick to the background and the background come away. If its the latter which is more than. Likely the case then it doesn't matter what primer you use. It would be worth watching my video on limewash paint to give you a good understanding of it mate. Hope all that makes sense
Just out of interest, why do you title videos like this as "most plasterers dont know this"? How do you know it then? And if you dont know this kind of stuff then you aint really a plasterer are you? You actually come across as a sound big guy but comments like "most plasterers dont know this" comes across as a bit arrogant and an i know better kind of attitude.
Titles just grab attention mate... plastering is a fairly boring topic to talk about so I need to think of ways to make people interested and want to watch
Fair do's mate, that makes sense. My apologies if I've came across as a bit of a dick in some of the comments. As I said you seem like a sound big dude so all the best ✌️
You’re dam right Kirk, been using only SBR for about 4 months now, miles better than PVA
Used to use a waterproof PVA
You know what I love? Plasterers who are convinced that a "magic mix" of SBR and PVA 50/50 is the way to go. I've never heard such shit in all my life 🤦😂
You're right...the correct mix is 75pc Sbr 25 pc..
I swear SBR is a gift from heaven. I use it all the time on so many different applications.

How long have you been plastering for mate? You needed a you tube video to learn about the superior properties of SBR compared to PVA, did the guy you served your time under not teach you these things?
I always thought once sbr has dried then it became more like a plastic so skim will fail , is that not right?
I'm going to start using SBR in the future. Thanks for your tips
Dont mate
I'm a tiler and use it exclusively its just a better product in every circumstance
I used sbr today on silk paint, after 1st coat ov plaster, started to bubble and full lot came down.
I always used pva when plastering . 20% pva 80% water never had a problem and anything that’s high suction I just apply a bit more to that area .I only use SBR in render. I’m not saying it’s better or worse just how I was taught to do it .
I like 70% sbr and 30% pva
Just makes life a little easier applying it , and still drys 👌👌👌
Thats a great tip, thanks, particularly the pva drying bit, ive suffered that a few times in the winter 👍👍
I use sbr on a lot of applications. I’m pretty sure most specialist primers for tiles or plaster or render all contain it to be fair
I'll give that a try, thanks.
Do u have to add water to it as ive some and its liquid form already
Great advice - top man

I am so addicted to watching these vids it's mad
Wow nice one Brother 👊🏽👳🏽♂️🖤 I'm gonna try it
And pva is made from a protein, mold lives on protein 💪,thanks my man great channel 👍
Well good damn it I wish I knew this sooner! Thanks boss.
I've only used it for outside work, wasn't even sure you could use it inside.
Brilliant stuff though.
Usually only use sbr with iutside work ill give it a try some time on new plaster im using loads of coats of pva on over skims
Once it is dry does it stay dry? I.E Can a coat an external wall and it'll stay dry?
Can you use sbr over lime plaster mate?

Do you 1 coat or 2 coat when you use SBR and does it need watering down or not..?
I’m a plumber so I haven’t much clue on plastering.
I wants my hall landing and stairs plastering. But the couple of pals I know that plaster said because of the walls are silk paint it’s going to be a nightmare and I’ll need gritty pva stuff,
So SBR will be okay?
Cheers friend..a wealth of knowledge 👍
Ooo and i love the smell 😂
Silk paint🤯 thanks for the tip
Does it need watering down or just neet for overskim and do you still 2 coat SBR or just the one coat for overskim
how does it work over artex ceilings that have never been painted, pva even after 3 coats never holds it back, Sbr could be the answer
Excellent thanks 😊
Thank you that is a very good tip
How about neat sbr over dry fresh plaster ?
Add the right gauge of water to activate, the original sbr back in the late 80's was poured out white from the tub then when water added, turned a bluey colour It's all I use
Only thing hold plaster back to long on matt takes ages to set on it
So works good on silk paint?
So do we apply it neat (straight from the bottle), or does it require any mixing to a ratio?
Neat
@@Onthetrowel cheers pal, thanks very much for the direct reply, much appreciated… i’ll give it a whirl, the wife just had me knock a wall down, and even as an amateur plasterer PVA never felt right.
I use SBR , it's miles better than PVA , also use it diluted for sealing floors before screed .
Can you do a video on how much to put on Kirk I think I’m putting too much on the ceiling I did yesterday still wasn’t dry after a hour or so but the walls was made no sense ??
Hey mate, I don't have it dripping, just a nice coat like you would if you were painting
If you sbr the day before when you come back the following day do you have to sbr again
Never used sbr I'll give it a go I take it you put it on let it dry then skim over. So for best results how much water.
40years plastering never used it but willing to try kirk
How do you stop the silk from bubbling up when you’ve plastered over it?
Sbr Sbr Sbr, beats the pants off everything else. So easy to apply. Goes miles and kills suction stone dead. Everyone here owes Kirk a pint!
All I think of with PVA is how it peels off your skin as kid. Sbr is like super glue
This video reminds me of a tune by "NEW KIDS ON THE BLOCK" in the Good old 90's😂.....
"Step.1 we can have lots of fun.
Step.2 There's so much we can do.😅
Step.3 Its just You & Me.
Step.4 I can give you more.
Step.5 Don't you know that the time has arrived.😂😂😂😂
You don't skim on pva when it's dry, you wait until its tacky, but yeah s.b.r seals alot better. Thissle bond it is good aswel
Pva is water based and re-emulsifys when it gets wet. You can leave it to completely dry and then when you put wet plaster on it it will go tacky again pal.
@@Onthetrowelsbr makes a great wood glue aswell.
Sbr is a bomding agent we add into tanking 😂 but if it work it works
So is SBR better as a primer for screed prior to apply floor levelling compound? I was gonna use PVA.
Use sbr
@@joshflint6070 thanks Josh 👍🏻
can you plaster over artex?
Your video gets cut off at the end, were you saying that you just apply it straight on?
Yes mate, use it neat
SBR.! & how much is it 3 times as much
used pva for 20 years , never had a problem
Hiya luv. Would you / do you sbr where you've knocked off back to brick and brushed all the dust off, before drywall adheisive is used?
Also... while I'm at it, would you sbr or pva moisture resistant plasterboard?
You don't need to sbr the bricks before using adhesive but damping the walk down helps if it's dusty.
You can skim straight over moisture board but if you read the product data sheet it states that you should use thistle bond it although nobody ever does.
(British gypsum boards)
If your worried about back grounds, do a little test dab and come back to it 24 hrs later. You can dab to ALMOST anything. But painted walls. , a wise man once said .😉
I've been saying this for years about re emulsifying
Some numpties are still using PVA on outside jobs, like slurry mixes! They'd be as well having a piss in it!
So I can do away with bond it pre grit and use sbr instead? If so magical 😜
100% yes mate 👍
The amount of plasterers i see that sbr then come back the next day is madness 😅
It's fine to plaster the next day mate
@@Onthetrowel yeah I know that mate it's just alot of guys seem to think you can't player the same day .
SBR is usually dry with about 30 minutes, sometimes a lot quicker.
What about thisle bond?
IV never looked back SBR all the way
If you scrape artex ceiling and sbr it you doing it neat? And 1 or 2 coats sbr?
Neat, 1 good coat
@@Onthetrowel yeah that's what I always do neat 1 coat.iv not had anybody phone to say it's fell on floor yet 😂 keep them videos coming buddy best plasterer /RUclipsr out there for sure
We've gotta long running joke between friends.😂
A joiner friend mentioned SBR being fantastic ....And drys like "BELL METAL"😮😂😂
Remember🤔😉 BELL METAL
same reason tilers use sbr not pva
SBR stocks after this video 📈
And number 5 ,because kirk said so 👍👍more top tips👍👍 kirk knows 👍👍
#4 not sure - I've never seen a plasterer wait for PVA to dry
I always hit dry unibond, re-emulsifies when wet and you don’t get that awful sliding over tacky walls
100% I always use SBR
I haven't used pva in years
SBR is Great but very messy
Hi Kirk. If you 1 coat SBR a whole room. Is it ok to leave it say 10 days then skim over? Or would I be best doing another coat?
Think you have told me before but can't remember what you said. 😂
It's fine mate, you could do it 6 months before if you wanted
@Onthetrowel you I definitely wouldn't sbr painted walls or artex and leave sbr dry , you are essentially just sealing the background you have to hit it tacky in order to stick if theres no key , that's why I always use pregrit
Yeah but it takes ages to pull in .
Ok I will try it 😂
You lay on to dry sbr?
Yes mate 😀👍
I prime then apply again, then apply plaster while it’s taking up, as it doesn’t re emulsify it creates a barrier once dry.
It dear as fuck though compared to pva
It's getting more and more expensive decent one now 25 30 quid
Straight from the tub or mix some water into it
Straight from tub mate
Workability is far better with SBR
Can you dot and dab onto SBR?
Yes mate
@Onthetrowel cheers bro.
Im using sbr for years
Agree is much better
Should be using thistle bond
Not at £80 mate
@@Onthetrowel it is extortionate but so’s the finish near £20 a bag after tax. But I’ve had 2 ceilings come down with pva and sbr. Don’t know why done everything right not cement in the finish or bonding. The other ceilings stayed on. So I use thistle bond on every ceiling now
When they came down... did your plaster come away from the primer or did the plaster stick to the background and the background come away.
If its the latter which is more than. Likely the case then it doesn't matter what primer you use. It would be worth watching my video on limewash paint to give you a good understanding of it mate.
Hope all that makes sense

No it doesn’t come across as arrogance. You’re just projecting and triggered by the sound of things.
Do you have an arrogant parent or something?

The best thing ever was a product call plastweld
Shouldn't plaster over silk paint, it will fail. Board it or peel the paint off.
love you to bits
