Gypsum plaster on Wimpey No Fines walls
Can anyone here offer guidance on the suitability of gypsum plaster on No Fines houses? I do general handyman work and some smaller plastering jobs, I have a returning customer who says they have blown plaster on an external wall of their Wimpey No Fines house (non-standard poured concrete construction without a cavity).
They want a quote to repair the wall but I'm not too familiar with this style of construction and wasn't sure if I could work with Bonding and Multifinish or would need to work with back coat plaster and lime? I've only dealt with gypsum products before so would likely turn the job away if it meant working with unfamiliar gear.
I'm going to inspect anyway and can assess if it was previously done in a gypsum product.
