Most stains, usually white stains, are a result of using plant fertilizer. In some cases, our SealGreen Efflorescence cleaner will remove the stains if the stains are efflorescence based. If not, the only way we have found a way to remove them is by color staining the concrete to cover the stains. Using our SealGreen Stain Primer, and SealGreen Tintable sealer mixed with SealGreen color stain.
