How To Stop Efflorescence

The acid in rain will eventually dissipate a case of mild to medium efflorescence over time. Depending on climatic conditions, this can take anywhere from a couple months to a year. In cases of heavy efflorescence, or if the client cannot wait, the following remedy will work for an extra fee:

• Wait for 2 weeks of dry weather to ensure the stone is dried out. This could be longer in the Winter.

• Apply 2 coats of siloxane sealer.

• Wait another dry week.

• Wash down with Vanatrol, or any light acid masonry cleaner, per the manufacturer’s recommendations.

• Do not powerwash!!!
