questions REBECCA on 22/04/2018

Can I use Rust-Oleum Mathys Secco Super on top of a masonry painted wall?


No, Rust-Oleum Mathys Secco Super must only be applied to bare, porous exterior walls and surfaces (brick, concrete, cement, etc.). For a previously painted surface we would instead recommend Rust-Oleum Mathys Murfill Waterproofing Coating.
