![]() | Question: Can I use Rust-Oleum Mathys Secco Super on top of a masonry painted wall? |
Answer from Rawlins’ Technical Team: 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. | |
