We've seen a few houses where to speed up the job and for ease of plastering the guys have either used too much lime or not enough cement in the first coat. This basically leads to the render being not very strong and easily dislodged. An easy way to test this is to chip off a section of the sand/cement plaster and have a look at the colour ( without any white set included ). If it is a medium to dark grey they have used lots of cement. A light grey and they haven't used enough. I'm pretty sure someone here on the forums will be able to point out the relevant AS indicating the minimum strength of render mix. Any lab would be able to tell you the proportions they have used on analysis. It is usually in the vicinity of 8 sand:2 cement:1 plasticiser depending on whether they used lime or not. If it is just the white set coming off, once again to speed up the job they may not have given the original render enough time to dry before doing the hardwall or have gotten their mix proportions or prep wrong. Stewie Re: Paint Peeling - Plaster too soft? 20Aug 14, 2015 6:13 pm I'm seeing the same problem in my home. Again the painter blamed the builder and vice versa. We used Duplux oil based plaster sealer but the paint still comes away very easily. I'm wondering if there are any other sealers on the market that will penetrate into the plaster and bond better. That way at least when we repair the bald patches, the new topcoat wont suffer the same way.
