Can unsealed MystiCrete absorb stains from mud, spills, etc?
The initial absorption rate of MystiCrete is 0.0031mm/sqrtsec. Organic materials (leaves, rotten wood, wine, etc) & salts could leave temporary stains – but would be washed away over time (by rain, etc). Inorganic materials (paints, rust, fine red powdery colors in clays & sands), and non-soluble minerals could cause staining to MystiCrete, as well as other concrete surfaces, and many stone surfaces. In these cases, pre-sealing is recommended with a breathable sealer (Siloxane sealers by Prosoco, etc). Follow manufacturer’s instructions when applying. Sealers will also make it easier to clean MystiCrete surfaces.
