We're renovating a 1930's rendered art deco style house and want to achieve a smooth finish.
It's been painted with a thick textured paint that scrapes off easily, but underneath is a mess, patches of old paint that won't come off, lots of loose render, but most of it is still stuck really solidly - will take loads of work to remove it all.
My Dad is a retired builder and thinks we could give it a rendered skim. He's suggested removing all loose material, hacking into the surface with an angle grinder to provide a key, then coating with PVA before skimming with 4:1 building sand:cement.
I've spent hours researching this on the internet and I'm really concerned we would be wasting our time and money doing this. Apart from anything else just about every reference to rendering I've found refers to using sharp sand.
Any views?
