Yes, we suggest starting testing in a small area not very visible with a none-diluted application to determine the strength of the product that you will need to remove efflorescence of limestone. The cleaning process is fast and simple:
1. Apply remover SealGreen Efflorescence Remover
2. Effervescence should be immediate upon contact with efflorescence. If not, you do not have efflorescence. It may be calcium or other type of stain.
3. Scrub lightly upon reaction and rinse.
4. We recommend sealing your limestone with SealGreen Brick and Stone sealer to mitigate the return of the efflorescence.
