I'm just a diyer. Who wish he could plaster like you. Brilliant video.
Really helpful video, I’ve always wondered the difference between hardwall and bonding and you’ve explained it very clearly, thank you.
A very helpful video describing these two products, their use and surface application. Thank you very much.
One of the best video clips I have ever watched
why is this so relaxing to watch ? I have a blown area but the substrate is smooth, they justed joint compound and it's just popping off years later....same area on both floors. It's not porous, so I think I need the PVA first. Get it done !
Very good Information, I live in the USA but have a house across the border to Mexico. Bought the house from my mother in law, 40 plus year old, home that was well built, from brick. But now, the paint from prior years is falling apart and cracking. Your videos are very educational and now I know what to do. Thanks A lot
great to watch , plenty of skill & as an electrician, i'm just chomping at the bit to get in there & put holes all over it
Great video. Thank you
I'm addicted to your videos....Can't stop watching 'em HAHA
Glad you like them! Thank you
Awesome, you make it look easy.
Thank you! Cheers!
Great video
Good break down on dealing with different back grounds, and how to use hardwall / bonding coat
Thank you. Much appreciated pal!
@@PlasteringForBeginnersits because blaine has a massive willy
Thank you for explaining PVA is not required for brick surface.
excellent video again blaine real world jobs !
Thanks pal 👍
Great stuff as always buddy!
Cheers pal!
Great job, I notice ‘damp Sam’ on UA-cam has been reviewing your videos, wouldn’t listen to it. Your top dog at your game, well done
Thank you matey! And yeah…I’m not a fan. He just slates everyone for views. It’s one tactic for views on UA-cam but not one I’m a fan of. Thanks for watching my friend, all the best 👍
Hi ya. Would it be a good or bad idea to SBR thermolite blocks before rendering to stop the horrendous suction. Thanks very much.
On brick i just use bonding but SBR it first. I just prefer not needing two separate products when prepping walls for a skim.
Damn, I did not know not to PVA hard brick 😢. I literally covered a 2.4m x 4m wall in PVA before applying a bonding coat. After hearing your explanation about the brick suction keeping hold of the bonding coat, I now see the error of my ways 👍
We're all learning my friend. Me also!!
Actually you were fine. The Bonding is intended to stick to low suction backgrounds such as concrete and engineering bricks so sealing something that has suction with pva before bonding is not a problem. Blane said that 'Hardwall' backing plaster relies on suction so that is the one you don't PVA. Just let the brick suck it in.
Thank you. If you can have a list of materials you used, that will be great. I have no idea what to buy.
Other plastering websites say that PVA should be used on brick walls to lower the suction rate. Now I'm confused.
High suction, and/ or deep use hardwall, lower suction shallower fill, bonding, just follow what it says on the bags,
Can you apply hard wall to brick thats has had a DPM paint applied to it?
I’ve got a gap between door liner and wall with lath and plaster. Can I use bonding to fill the gap?
Love the videos, but why or what causes the plaster to blow in the first place ?
What do you use if there's efflorescence on internal upstairs brickwork?
I want to try my hand at plastering but all the damp proofing I can find seems like it wouldn't give a good key for suction with thistle hardwall.
hello do you have a link where i can get that mess , i have a job almost the same coming up , im not a plaster just a dad helping out his kids but i have no idea where to get the mesh ,.
What's the difference between hardwall and sand and cement mix? I have exposed Victorian brick
Hi Blaine can you use hardwall and bonding on the same wall but for different backgrounds? I have a wall that is brick but with a studded and plasterboarded area that used to be a doorway, would I just scrim over the joins between the hardwall and bonding? Cheers
Yeah you can and yeah, scrim the joins beforehand.
@@PlasteringForBeginners cheers 👍👍👍
Hi Blaine, great video…question: I’ve used bonding so many times but make it up as I go along regards timing. Never used hardball but need to on next job. How long do you wait before skimming over bonding and hardwall? I think I remember you suggesting when bonding coat starts to Darken. Is this the same with hardwall? And is it just multi straight on? Or do you PVA? Thanks in advance 👍🏻
Quick question, I've got painted brickwork that I want to plaster over, would you still use hardwall to cover it at first instance?
No, use green grit first.
That's the one!
I always find that when i skim over bonding i get lots of little air bubbles, any advice on how i can stop tips from happening ? Cheers
You need to let the bonding go off further & the bubbles shouldn't appear.Likewise if you apply your 2nd coat of finish to quickly the same thing will happen.
Awesome job again blaine, did you pva the whole wall before bonding
Thanks Tom, maybe that's where I got wrong then, if I have a bad back ground I usually pva before bonding anything
Cheers and yeah, I did matey!
I've just had this on every wall on a garage extension that was done badly 20 years ago, the inner skin was thermalite, and it looked like they didn't wet down the blocks, and their mortar mix was way to strong so it just sucked all the moisture out of the mix, you could literally wobble the blocks, I had to hack 75% off and bed mesh in on a tight coat of bonding. Over the last 20 years the jobs have just been getting worse and worse, might see if mcdonalds are hiring. 😂😭
In Ireland we always x up the original coat of hardwall with a Stanley knife before pva for reskim to give new coat a key as well as the pva Iv noticed you lads don’t bother can I ask why that is ?
Yeah I do the same your only sticking it to the paint then... if the paint is waterbased it will just peel off
When I worked on sites in the UK, the plasterers always did that to the base coat.
what causes the plaster to blow, there has been times when i put my second coat on i can get a bubble (blown ) patch.. ps im just learning on a old council house ,im using it as a workshop so im lucky on that point..
Its a mixture of things. Age of the original plaster, bad application of new plaster (usually lack of hydration at the beginning leading to the plaster failing), not enough of a key...there's loads of reasons matey. It's quite hard to pin point!
@@PlasteringForBeginners thanks for replying ,i often can get a bubble appear on my second coat maybe i am leaving it to long before i apply the second coat .only trial and error i will figure it out,
Can this be used on 100+ year old house? Removed blown plaster but it's the old stuff with horse hair (I think). Or do you have to use lime plaster for flexibility on old bricks?
Lime plaster is best because it will allow the soft brick to breath.
I've been out to a couple of jobs where walls and ceilings with bonding coat under skimcoat has come off the wall, usually a painted wall underneath. Would PVA really make much difference to getting the bonding coat to adhere ?
I use Murexin Supergrund D4, it's an effing monster, makes loose or porous substrate much, much firmer. The surface feels a bit like sandpaper after it dries.
I keep hearing the term 'tight coat', can you clarify what this is please?
Is it putting the 2nd layer on before the first layer has set enough in a normal scenario? I initially understood it to be putting a second coat on with the same mix as the first?
A tight coat means a thinly spread coat of plaster/bonding. For areas that aren't deep and don't need filling out alot, they only need a tight coat. Hope this helps
That's the one Ryan!
👍👍

Why use bonding coat and not hard wall thistle
I remember you did a video testing out one coat plaster and you said you might use it if it saves you time etc. Have you been using it at all?
I did a test of one coat plaster but I don't recommend it mate
Do you never use a speed-skim on base coat plaster?
I don't recommend it pal - use a proper straight edge or Darby👍
What product would you use if the original plaster was lime?
I'd ask the building supplies company what they recommend. I had spalling concrete in a ceiling and they told me what to use there and it was different than what i needed in teh hall way (Window was leaking and concrete skim coat was just crumbling).
Always wondered how do you cope with that terrible scratching noise during plastering for 8 hours or more at your work 🤔?
Noise block Headphones with nice music. Believe me you will be in different world and guess what? The job is done without thinking.
@@bS-he5pn seen many of the plasterers but never seen them wearing headphones. Maybe they're used to it
PVA 1st
What about a painted brick wall? Hardwall or bonding?
Bonding
Bonding 👍
Why did my plasterer drop so much plaster on the floor?
Amateur?
How fick is it supposed to be?
