Great video - informative, no nonsense and knowledgeable. Would you use bonding where an existing wall is next to a plywood surface, which will also need to be replaced eventually painted and be part of the finished surface? Thank you
I’d try to strip off the ply and replace it with layers of plasterboard but if that’s not possible I would probably stick loads of pva on the ply and edge it with mesh at the junction with the surrounding surface. You want to avoid different suctions.
Nice work!! I came here as I was looking for filling an old chase which had two 15mm copper pipes in it. The depth is 30-35mm and 60mm wide. Is Bonding Coat still OK in layers? The blocks are breeze blocks.
Yes, bonding goes on well if it’s new plasterboard. But if it’s just a flat surface, wouldn’t you just go straight to skimming without bonding it ? Maybe I’m misunderstanding
@build-better-things do you need to PVA/water wash the chasing of where there is a cable thats been wired onto breezeblocks/dense block before using the bonding plaster? Thank you!
We’re did you learn to plaster because I have been a plasterer for more than 30 years and I tell something looking at the sate of your work your in no way a time served plasterer
Hi. I am definitely not a time served plasterer. I think I made it clear when I said “DIY” in the thumbnail. What point are you trying to make? Would you do something differently?
You can use hardwall over larger areas of walls such as unporous brick, but for all the examples I have shown in the video, being chases and junctions…, I would use bonding rather than hardwall, with pva where not plasterboard. In the examples I show in the video, where exactly would you prefer to use hardwall?
Spot on. Thank you.
Excellent informative video - many thanks
Thank you for commenting.

@@build-better-things understood & makes sense - thank you for the quick reply!

Yes, just build up in 10mm layers. The quick curing of bonding means you don’t have to wait so long
@@build-better-things many thanks for your reply.
Great video thanks
Would not use bonding at damp course level or solid wall for that matter. It can draw moisture and salts
Thanks for the comment.
Sir can you use bonding as rough coat on plaster board then finish with mult finest thanks.

@@build-better-things it's new plaster board. I left 9mm gap to existing board so I need rough coat 9mm then finest skim 2mm multi finest
@@build-better-things thank you for your reply 👍

I think you've answered by question at 3:06. You PVA wash the inside of the chases before applying the bonding plaster?
Hi. I’ll Pva the masonry before applying the bonding.

should use hardwall on brick

yes I would use hardwall hardly ever use bonding, bonding can cause all kinds of problems@@build-better-things
