Yes, SealGreen Mold and Mildew Remover is compatible with Limestone. Please be aware NOT to spray the remover on metal or glass because it will stain them permanently.
The application process is as follows:
1. Mix SealGreen Mold and Mildew Remover according to the instructions
2. Apply to surface using a garden sprayer
3. If your mold is very heavy or old, we recommend spraying the surface to soak, and let it remain in place until next day. It does not matter if it dries.
4. If the mold is light, then apply the cleaner and allow to rest for 5 to 10 minutes and then rinse.
5. Using a pressure washer with no more than 3,000Psi and a green tip rinse the surface
6. We recommend sealing the limestone with SealGreen Brick and Stone Sealer to mitigate the return of the mold.
