A grinder will probably be the easiest. An alternative is to hire a Needle Scabler. 04 Jul 2006 8 Melbourne / Sydney / Canberra Junior Member Re: rendering over paint 3Jul 31, 2006 5:06 pm Yes my post here is most likely too late as well. But for others, here goes.
Rendering over paint is not a good idea. If you are applying a skim coat to fix cracks etc. Yes you can do that by partial removal of the paint. But a thick coat or render will not stick to a painted surface. If rendering was a must then a better way would be to fix expanded metal to the painted wall and render on to that. Another option is to stick plasterboard to the surface. Chip off the paint at 450 centres about 50mm diameter, then use cornice adhesive to stick the plasterboard. Hope this helps Rod Dyson 03 Aug 2006 11 western australia Junior Member Re: rendering over paint 4Aug 03, 2006 10:14 pm also note if its an older house check its not lead based paint. ******* builder got me to grind back paint on old house as gullible apprentice about 10 or so years ago and he then left site very quickly. have had no side efeects luckily but not nice for neighbours either.
i like plaster brokers idea of using expansion metal. a lot safer all round yep you need a joint, foam is easiest, will look fine once rendered with a joint. 2 2653 DIY, Home Maintenance & Repair Unless you have a damp issue, either failed waterproofing in a wet area, a leaking pipe or rising damp, moisture shouldn't be an issue.
