Hi...tried this on the Masonry forum without success...wondering if might be more appropriate on here.
Decades ago my neighbour built an ugly breeze block wall between my back garden and hers. I think the blocks are the high density type that have the rough grainy texture.
I've considered painting them to make them look a bit more attractive but think it would be nicer to put a rough render over them. So....
1. Is it possible to render breeze blocks?
2. Would I need to prepare the existing surface in some way?
3. Since I'll only be rendering my side of the wall, is there a danger that damp getting in the other side will end up blowing all the render off, and can I mitigate this in some way?
4. What mix should I use?
5. Any advice on technique? Can I just get one of those rectangular plastering trowels and just slap it on?
Cheers for any advice....
