Hello
Long time lurker first time poster.
I've had my 1920's home fully dpc injected and all the downstairs stripped of all original black ash/sand/lime plaster (we took it all off, not just the lower part as it was blown in places anyway).
Unfortunately we are not able to re-render/plaster with the same materials (lime) as the new dpc spec requires a s&c backing. Obviously much stronger than lime so not ideal but we decided to go ahead after lots of research/advice (looked into renovation plasters but would invalidate guarantee).
The plan was for two coats of s&c to flat out the walls and then skim with multi. When the plasterer came to do the job he advised that its common to get lots of cracking (he described it as jigsaw puzzle like cracking) when plastering on our type of soft red bricks and suggested that he do the first s&c scratch for the damp proofing then dot and dab.
The scratch has been done and he says if we really want to go ahead with skim then he will come back and do the second s&c then skim but really advises against it.
We're not very keen on d&d and were really hoping for a solid skimmed finish. I'm wondering if leaving as much time as possible between the s&c backing and skim would minimise the risk of cracking? Would it be completely bananas to line all the walls with fibreglass mesh before the skim coats as an extra precaution?
Any advice would be greatly appreciated!
