I need to render an external wall.
It's currently bare thermolite blocks (light aerated block)
I'm thinking -
Pva it.
5mm or so 4:1 sharp sand / cement mix
Render mesh
Another 5mm of the same mix over the top.
All applied together (ie wet on wet)
Is that the right sort of idea?
I can plaster gypsum fine (I'm not a pro, but I've done more than one friends place also) and I'm fine with lime, but I've just never done cement render.
Thank you.
