hi guys, firstly if this is allowed, I'm a heating engineer/gas fitter so happy to try and help with any gas questions
I've just taken the roof off my bungalow and added a second storey, the existing common bricks had 50 years of paint and the new top part of the gables are in lightweight concrete blocks. I have put a Refina scabbler over the painted bricks and raked out the joints however there are still patches of paint ingrained in the brick faces.
My question is , the old skool renderers talk about a scud coat of sand and cement, would you add sbr to this and the subsequent scratch coat and finish?
Just slightly concerned that in years to come a crack may develop where the blocks have been laid on top of bricks on the gables?
Have decided on traditional sand and cement render due to cost and just need it to stay on the wall for 20 years before they put me in a nursing home lol.
Seriously, really appreciate your thoughts on a failsafe spec, thanks in advance.
