Hi! I recently lime washed my stone fireplace. We love the way it looks, but are now thinking the previous owners must�ve stained the stone because the limewash is still pretty dusty and not entirely calcified. Will this product work to seal the lime washed stone? SAMPLE - AFM SafeCoat, WaterShield Concrete & Masonry Sealers

We spoke to the manufacturer about your question, and they raised the concern that the alkalinity on the stones would be too high (anything over 10pH) to get a good seal. We do sell samples if you would like to test, but otherwise we have no recommendations for you until the alkalinity goes down.
