This Stops 90% Of Beginner Plasterers…

[@samhines5084]

I use SBR sets in 15 - 20 mins never had a problem personally

[@worklife4221]

Same here

[@petermc1743]

I haven't worked out what PVA is any good for. It certainly isn't plastering in my experience. I've given old plaster 4 or 5 coats before now and it's still sucked like a basket full of kittens. I've taken to 'bond it Plasterers Pregrit' (you recommended it a few videos back) and it works wonderfully across everything I've encountered 👍👍

[@danishhussain804]

just use sbr mate

[@richardpowell9238]

Hi Blaine, great video, inuse pva all the time, ive tired using sbr but never got in with it, is there any reason you dont use sbr ?

[@Toliani4]

Just use SBR over all points

[@TheNomadicTrader]

I've used this and have some left over due to having issues with it emulsifying when getting the plaster on and it becoems really heavy and wet overall. I have used it with SBR in since which prevents the background from absorbing any moisture and provides a mechanical key at the same time.

[@PlasteringForBeginners]

No way…interesting. Never had that but I’ll bear that in mind. Thanks for the heads up mate 👍

[@TheNomadicTrader]

@@PlasteringForBeginners yeah on old battered boards where the paper was ripped. The grit didn't seal the board and activated again with the water in the plaster and the moisture got to the background and caused blistering - had it on a ceiling and 2 walls early on using it. I mix it up with SBR now if I want a mechanical key so I get the be best of both. Also, if you find that you miss a bit with the grit, be careful when applying a second coat as it activates the first coat and gets very very wet. I ended up having to scraped back the entire room as the labourer did a sh*t job with gritting the walls.

[@RyanRickles]

Would you use this over brick? I thought you wanted the suction so the plaster bonds well to brick. I’m a newbie just here to learn. Thanks

[@eaminslim52]

Hardwall or bonding if youre not worried about moisture and lime based renders if you need vapour permeability

[@petespencer5260]

Hey Blaine, hope you're well mate. I'm thinking you'd still need multiple coats of bond it on old bare sand and cement (eg. A bathroom strip out where tiles have taken finishing plaster with them). What do you think?

[@PlasteringForBeginners]

Yeah, definitely mate. Always fill the area flat if you can…still needs a coat of PVA/ Primer beforehand though so you’d still need to prep it 👍

[@simonhughes1641]

How does this stuff compare to Bostik Cementone Plasterer's Stabilising Primer? It’s almost twice as expensive and just wondered if that was the elite primer? Thank you

[@polory1000]

Totally agree blue grit neat is horrendous stuff I only use it in combo with pva 50/50 blue grit to pva then a bit of water , that pre grit is nicer to use and cheaper which is a plus , with that many backgrounds to go on Id tend to use a coat of sbr then a coat of pre grit personally .

[@PlasteringForBeginners]

Great tips…cheers matey. Thanks for watching 👍

[@BigSteveFairchild]

Great video

[@dannysingh8351]

Was wondering if we can plaster on old plaster after removing wallpaper. Its litte moldy on some parts. What preparation have to be done before plastering

[@joejames6696]

Use some coats of pva maybe 3 let it set then you can plaster over it

[@robbyricch3437]

Hi mate any idea where I can get that knauf stuff to skim a wall or any other recommendations what to use? Thank you

[@greenup9913]

Knauf used to be the best for new board work as you could get very big areas on, but unskilled people would really struggle using this, infact many decent plasterers could not get the hang of it. its no good at all for reskims, just use multi finish for all general work

[@MrRdt1970]

Wickes but comes on a bag

[@Reprogrammed_By_SEGA]

I don't recommend using plaster board on ceilings, it starts to pull off the ceiling after time. It seems like an easy fix but you will pay for it later down the line. @PlasteringForBeginners btw what do you for an artex ceiling that has lime wash paint?

[@pcno2832]

What would you use in place of plasterboard? Every house in which I've ever lived had plasterboard of some kind on the ceilings, and none of it came down. I know it happens when the builders use too few fasteners, or fasteners that aren't deep enough, especially when there's a foot of insulation piled up on it, but there are more wrong ways than right ways to do everything.

[@villaman2261]

Old plaster board will need primer or one of the plastering agents

[@raj080288]

Would the pva on a painted wall be dilited or pure?

[@PlasteringForBeginners]

3:1 mate. 3 part water, 1 part PVA 👍

[@johnkushnirenko4337]

Hi mate I think its worth a mention when skimming board. If the board is old and has been hung for a while it usually does need a coat of SBR or pva. I know plenty of people been caught on this. 😊

[@jmortier71]

What's pva ?

[@PlasteringForBeginners]

Very true my friend! Anything over 6 months is worth prepping with a coat of PVA beforehand. Thanks for the heads up pal 👍

[@benp9208]

Sbr more superior over pva blaine??

[@pestsandclays]

Pva has had its day now, SBR all day long !!!

[@Wmac5]

Hi Blaine. Do you have to pva or wet wall before using bond it ? Or can it go straight on old walls. And next day is it ready to skim or again does it need a coat of pva ? Thanks

[@bishop57655]

Straight on old wall fella just make sure you scrape away any loose bits..ready to skim the following day and no need for pva

[@Nickpaintbrush]

Would SBR do the same job?

[@PlasteringForBeginners]

Yeah mate 👍

[@Darrida]

Only children and plasterers have the privilege of writing on walls.

[@PlasteringForBeginners]

Hahaha perks of the job 😂

[@theemperor477]

Has anyone tried Pink SBR yet?

[@Jlw1539]

Hey, I've never used this before and don't have the time to get in the day before to apply. Does one to two hours before plaster definitely work??

[@PlasteringForBeginners]

It just depends made…depends on the background, the area you’re working on, temperature, dampness etc. There’s too many variables to ever say for definite pal…but 2 hours worked for me 👍

[@Jlw1539]

@@PlasteringForBeginners cheers mate, I'll see how it goes 👍

Thistle bond ? The whole wall maybe?

SBR all day long 🙋

Just reached a bump in the mortgage rd ,won't proceed till the work is carried out ,3 bedrooms need replastering, which i was going to do myself, is that normal ,wanted to do most of the work myself to save money ,just having a moan 😀

[@richardaddy1280]

Skimming hard wall the same day is not why British gypsum recommends is it. Leads too blistering

[@PlasteringForBeginners]

It’s the most commonly known way…don’t know what British Gypsum say but it works well for me. Done it since I was a teen and never had issues 👍

[@alfamad155]

Blistering will only occur if the hardwall isn’t sufficiently set just the same as if you were going over bonding.

[@richardaddy1280]

@@alfamad155 exactly which is if you read the bag isn’t the same day

[@alanoakley6120]

Hardwall in the morning, skim about 11.30. Finishes lovely, no blistering. Been doing it since I was a nipper. If you leave it until next day your not a proper plasterer

[@richardaddy1280]

@@alanoakley6120 what following what brittish gypsum says makes me not a proper plasterer. Best burn my papers and find me another job then
