I was looking at the render on the side of the house over the weekend and thinking that it might be time to do something about it. Its an extension done in blueboard and the render has cracked on all of the blueboard joins. Do you think there is any way we can patch it or do we have to go the expensive route and pull off all the blueboard off the house and clad it again?
Looks like there wasn't allowance for the boards to move. The reasonably dark render colour probably doesn't help with the movement - especially if they cop plenty of sun. I think you would have to pull them all off and start again. I wouldn't use blueboard but something like Scyon. Can look great.
I don't really understand why people render - the darker colours often seem to crack and the lighter colours attract dirt and grime. I think weatherboards or brick are far preferable.
I think there has been some good merketing with before and after shots of just how good it looks new with no mention of what you have a few years latter.
At home the old unused wall airconditioner survives because it is a pain trying to match 1950's bricks if it came out, also had a similar problem with the meter box and the eventual fix was a new box inside the old one to avoid moving it and leaving a hole to be patched.
