- Want to learn how to lime plaster? We've been doing a huge lime project in Lancashire and our team are here to talk you through it from start to finish.
It includes a spot of old-fashioned lime plastering onto LATHS! This old method of plastering has been replaced by plasterboard nowadays but for older buildings, you can't just put plasterboard in. You have to match type and this chapel near Preston needed some proper lath plastering done.
This How To guide in Lime plastering has been developed by the experts at UK Restoration Services. Following watching this video on lime plastering viewers should be able to have a go at plastering there own homes and houses.
This is the same chapel in which we installed a Limecrete floor a while back: • Limecrete Floor - How ... The next step is lime plaster on the walls, and you can follow along!

@@UKRestorationServices been at it for over 20 years, just never get the chance to use lime much... miles more rewarding
Brilliant work and very inspiring, how would the product that you’ve put on the walls differ to what was used on my home back in the victorian / Edwardian days, where all the what I assume to be lime render starts to loose it’s bond with the brickwork and literally just pulls off by hand? Is that just a characteristic of lime or did they do something wrong back then? Thanks for uploading the video, really great to see proper craftsmanship.
Hey Michael, the lime processing nowadays is much more refined than 150 years ago. Most calcium oxide for the hot mix now comes from mainly 2 sites in UK, Buxton & Shap. In the past lime burning would have multiply processing site in every town. The lime purity would vary depending on the extraction location. This would give different setting strengths.
Lime plaster should not achieve the strength of a modern gypsum plaster. However most failures of existing plaster on historic buildings is due to water ingress, modern living and external impervious barriers.
@@UKRestorationServices thank you for taking the time to reply, would really like to learn more about it so your video was great!
A lot of it has got to do with type of sand. Leighton Buzzard sand is the best for stickability.
I'm surprised he's not wearing gloves.
Lime burns my skin into stingy rashy sores, takes 2-3 weeks to heal.Very caustic!
We have guys who are effect with lime on their hand and always wear gloves. Others it doesn't really bother. Vinegar at the end of the day helps.
It depends on your skin type. It doesn't bother some whereas it burns others. Weird. It never bothers me.
No breathing masks when mixing, no eye protection either. Yes, I know the lads of yore didn't have them, but what were the injuries? A master plasterer told me that when he went on site way back when he looked like a mummy - but he didn't get injured.
All proper tradesmen are only on youtube now. All rest just cowboys. Especially in essex.
Hopefully people will be more confident to have go after watching
🤠 I'm a cowboy
That’s nonsense some people just want to go to work and rnt interested in filming for UA-cam
If you say so shaggy
Thought I’d give it another try, and say great video, thank you for uploading. Why do you guys do diagonal scratches rather than figure 8 or wavy scratches? Just personal preference or some other reason please
You find the diagonal scratches historically in old plaster. However I would suggest as long as a good key is formed the pattern is irrelevant.
@@UKRestorationServices thank you very much)
Maybe 5th times a charm, just wanted to say great video, thank you for uploading. Why do you guys do diagonal scratches rather than figure 8 or wavy scratches? Just personal preference or some other reason please
I think it provides a better key and helps even out shrinkage as it provides uniform reinforcement. That and theres no risk of accidently slipping into a horizontal or vertical join of the block work or lath behind
@@Parkour_People Thank you)
do you ever use flax fiber? If so, how does it compare to the fiberglass stuff?
Just hair. Read Nigel copsey
Are you using lime putty and sand for 1st coat? what do you use for 2nd and 3rd coat?? David
Yes the base and float coat are hot mixed with Calbux and used hot. The top coat is mixed hot but used cold. This is except the laths which I think on this was mixed with 50% NHL 3.5
I thought you weren’t supposed to use lime plaster below 5°C?
Hi , i have a little cabin made with Osb. And i would love to try Lime plaster. Is it possible or not? What are the recipe for thé three stages?
You could just fix some EML on some counter battens. Probably easiest mix is a NHL 3.5 mixed with 2.5 parts course sand, leave over night. Remix next day....then crack on, dont mess with it to much. 2 coats 1st at 10mm 2nd at 6mm. Mix up NHL 3.5 to 1.5 parts Silica sand leave overnight...same as above. 👍👍
@@UKRestorationServices thanks
Is that a hot mix with quicklime ?
Yes, the plaster hot mixed with Calbux 90, except the top coat.
If u will
Per se
Not sure if my comments are being filtered or deleted
Hey, comments are on for this video and are not being filtered.
Thought you were adding asbestos 😅
Can you even buy asbestos anymore???
Plasters use a devil float to scratch the plaster that makes the key
Hey, devil float are OK for Bonding or Browning coats, however the scratch size in width using a devil float is 2-3mm. If you are using a traditional lime base coat / float with 3mm> aggregate. There will be an issue with the lime plaster penetrating the scratches. With a lath scratcher this will open up the plaster to 7mm-8mm allowing 3mm> plaster to bond / key better to the backing coat.
If you don't have lath, could you use nails/screws bashed through a bit of wood?
Masks, no excuses masks.
The music is totally distracting and unnecessary, I want to hear what is being said, not the thump thump thump of the beat. Please, drop the racket.
Thanks for the comment.....noted.
Dudes rock!
I totally agree! It's like listening to music on some boring induction video on a building site 😂. Very good explanation though.
@@MrDziuka dudes rock tho

some people can't hold themselves when it comes to complain about everything... and yet, they can't make better... the video is nice. I didn't even noticed the music in the background, because my attention was on the work and on the explanations 👍💪
