External render

Post by flyinghigh » Mon Apr 23, 2018 8:50 pm

I have a new breeze block shed. The walls are very porous. I want to render them. What stages should I do to render it? What mix and waterproof additives should I use on each layer ie the scratch layer (how thick) and the top coat? Can I use sharp sand for mix?
