Hi.
I've just relined a brick party wall with sound insulating PB. It's 15mm PB with a rubber-foam-rubber backing roughly another 15mm thick. To get the best result the boards have to be fitted so that the backing isn't compressed. On an uneven brick wall that means that some areas will get a bit squashed but no big deal. Main problem is that the boards have to be fixed using screws (I've used masonry screws as they're quicker/easier than wall plugs). Often you have to fit a washer to prevent the screw head pulling through. The finished boards are ok but a lot of the screw heads/washers aren't flush. To get them flush would damage the surface of the boards.
So, question is do I skim them, assuming that in certain areas the first coat will run up to but not really cover the washers/screws but then the second coat will. Or do I put a thin bonding coat across the entire wall to smooth everything out and then skim?
