I sometimes remove the rads but I was on a job with my mate and he got the plumber out to take rads off and he had an absolute nightmare. Took him most the day as he ended up draining the system and replacing old corroded valves. Made me think twice about removing them in future.
Thin mix skim with hot water …PVA walls…flatten first coat quick…add some water to mix second coat thicker… boom perfect 👌
I like to add fibres to the first coat on walls like this and on overskims in general. I use betokontakt or PBR Accrofix no need for sbr 👍🏻
Thanks for the video, they are really helpful for untrained
Another cracking video Alex, always informative mate all the best👌🤙🏴
When a heavier coat of skim is required on rougher backgrounds like this I find Board Finish pretty useful as it's that bit more rugged than multi, slightly bigger aggregate grain in it, fills in better I've found and still a great polished finish 👍
Nice work though mate
Totally agree on a bad dry wall. Board finish fills in much better than multi.
Quality work 👍🏼
Like glass 👍🏻
Great job thanks
Can’t believe you didn’t wedge an old towel / something to stop it falling into middle of rad, where you ain’t getting it out.
Top job Alex
Great video Alex. Could you have used magic mix in that situation. Thanks.
Magic mix as in the smart mix for the first and second coat?
Or hardball mixed in with the multi?
Think Martin means a few handfuls of Bonding thrown in with the Multi finish. I was going to ask the same question. Gives it more body.. I'm sure Alex has used it before and done a video about it... I remember watching it! 🙂
Good video bro 👍🏻
Two Thick coats pva would of done it iv come across these walls for 15 years it’s always work for me no need for SBR
Good skim tho great technique
Agreed. A watery coat of PVA first to soak in then a heavier coat. Ideally applies the day before
Pvas is great if you doing a bag of skim a day.
Why would you waste time doing 2 thick coats of pva when one coat of sbr would work better? I’ve sealed old render like that with it and it’s been dry and no suction within 20 minutes
Thanks for this. I've been watching your videos as a near beginner as I have lath and plaster walls to fix. I've bought the 1m fibreglass reinforcing and blue grit based on your other videos. In the other videos you've highlighted the importance of timing. Now I'm worried as you have 2 coats of SBR on and still went full speed. I won't be capable of being fast. Am I taking the blue grit back and putting on 3x coats of SBR, or will 2 coats of BG do the job?
A spatula isn't cheap, using a trowel will slow me down even more, add in applying the reinforcing and it now feels like a perfect storm on timing. Is it feasible?
Thanks for the videos, they've helped loads.
Hi Alex can you do more videos on pebble dashing & floor screeding?
What ratio did you use for the 2 coats ?
I do admire your workmanship and your videos, leaving skirting on is okay but not the radiator, been to a few jobs where the radiator was left on and it doesn’t look great. One tip , always ask your self , what if the owner of the house decides to change the radiator position? It is a simple skill to learn and charge the customer for removing and rehanging the radiator. Cheers
Have you ever had a radiator valve let by? My plumber mate came out to remove a rad and had an absolute nightmare with it, let alone a plasterer fucking about with it. The onus is on the client to think ahead with regards to different rads and or getting a plumber involved
Unfortunately the comment below is exactly why we don’t. Not only that our PL doesn’t cover us for water damage.
Many years ago I had a weld break on a radiator, it took our to fix and a costly one. The homeowner was given the option of using a plumber we have on call to take it, off they didn’t as they thought they could get it off. We only found out when we turned up to plaster that it was still on.
“The rest they say…..is their problem” 😂😂😂
It does look rough when ya look down a radiator that hasn't been removed. Touch wood I've never had a problem loosening the valve very slightly, dropping it to the floor, then nipping it up.
@@michaelbennison82them get the client to remove it for Christ sake. It’s not the plasterers responsibility to get a plumber in out of his price. And who stands above a rad and looks down it, answer is nobody does
Then it's something you tell the customer they need to have done before you arrive.
Great video lots of tips 👍🏻could you sponge float a wall like this / would there be a benefit or disadvantage in doing so?
Pva glue ? Sbr ?
I picked up on that you said you put the second coat on thick🤔 so how thick can you go with thistle on 1st and 2and coat if you have it.? Great video
you can probably apply multi finish at around 4mm thick with a bit of practice and still maintain a good finish. ideally it should be 2-3mm on the first coat and 1-2mm on the second coat on normal walls.
Alex question can you put a colour into pva to see where you have applied it.
Add a hand full of bonding bro
Would it be a good idea to use stabilising solution first to walls like this before sbr if time is not of the essence?
Great video. Got a few rooms to do soon like this.
Wouldn’t make much difference tbh as stabiliser is used for sealing the walls when they are chalky rather than porous.
I noticed you have commented on several videos. Thanks for the support on the channel in watching the content. It’s much appreciated.
@@AlexMorleyPlastering Thanks very much for your reply Alex, very much appreciated. Yes I have a few rooms where when I Stripped the paper the thin whitish plaster came off with it and has gone back to the sand/cement scratch coat.. It is dusty as hell even after hoovering.. So my plan was to stabilise it first.. Then sbr to try to help.. I'm a multi trade so not my full time thing so having people like yourself sharing your skills and knowledge is extremely valuable and helpful. You do make it look dreadfully easy though mate.. And always look too clean! I need jet washing down sometimes afterwards 😅
Best wishes buddy
Hi Alex. I love your channel. I use sika SbR a bit on different things it's a great product. Did you leave the SBR dry before skimming or just tacky?
Just left it for a bit. SBR dries very fast so it’s not such a big deal.
Do you thin this down? With water?
Do u use sbr neat or water it down
I used it neat on this occasion as the walls were so bad.
Hi Alex just a question have you ever came across woodchip paper before I’m guessing u strip it back then you prim it I’m guessing
As wrote comment it popped up
Homeowner stripped the paper off in between looking at the job. Hence why I didn’t realise how bad the wall was.
Alex can I use SBR after wallpaper has been removed to prime the left over wallpaper glue? And then skim onto the SBR?
SBR or PVA would work fine. Wallpaper glue isn’t a major deal. It doesn’t effect the plaster holding on the wall.
@@AlexMorleyPlastering Thank you man. Your videos are great. Didn't like the one with the dog poo on the stairs and ladder though 😂
Hi Alex, putting sbr on an internal wall.will the wall still be able to breath?
Breathable walls is necessary for walls with no cavity. Not the case with modern building. Also Multi finish is not considered a breathable product. You would need lime plaster for that.
the walls will not breath with multi on anyway.
Can you skim over SBR that has fully dried ,?
Yes. 👍
@@AlexMorleyPlastering thanks,👌wasn't sure if it had to be tacky unlike dried PVA that will re emulsify when wetted up with skim.
What make is your 18 inch carbon steel trowel
MT 18x4
You look like Stewy from succession
when the next video mate
did i only see oonly one coat?
No, not on a wall this bad.
Nice job.... porous walls are terrible
Sorry but plastering a wall with a radiator and skirting on is dog rough dont care how good you are you can never do a good job .....
Does that make him rough?.. if the customer doesn't wanna pay a chippy to refit skirting or doesn't know how or want to pay to take the rad off that's there choice.
Yea right O.
What are you on about, probably 80% of jobs have skirting/architrave on unless you’re doing new builds or complete rip outs. And did you not listen to why the rad is on, it’s not the plasterers job to organise a plumber to come out. And with regards to taking it off yourself, good luck when the valves are old and it lets by
Obviously never had an issue with a radiator then have you. Not worth the risk if you knew how badly it could go wrong. Up to the client to sort that out.
What a load of crap
Superdry walls 😂 erm....... 2 licks of pva?
Stop talking get on with it. It's going to dry up! 😅😅😅
😂😂😂
If you're plastering around a radiator you're a bodge artist .... if anyone wants to learn skills this isn't the place
Hey, have you ever thought of showing us how you made up the plaster for the wall? OH MY GOD, You actually want to be paid for nothing???? As you Brits say, "How Cheeky".
