Hello we have to paint the inside of a externally rendered single skin blockwork garage to cover up unsightly efflorescence marks.This is what the surveyor has asked for “painting the internal blockwork with a fully breathable paint that has an SD-0.01 breathable rating and is naturally alkaline so will offer mould resistance qualities. It must also be wet-scrub resistant and must be compatible with concrete blocks and efflorescence salts.”

please could you help
