Hi folks, 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....
