Sealing grout is unnecessary with this product!
Would RecommendI love this product. I have used this before. It is a great replacement for water to mix the grout. Sealing of the grout becomes unnecessary when using this product.

Worthless-don't waste your money!
Would Not RecommendI purchased this to use when regrouting my white ceramic tiled kitchen countertop, hoping that it would do what it said it did. I should have saved my money and used plain water to mix the grout as others have said. A few days in, and the grout is already stained from drops of coffee and tea. Save your money and use water! Very disappointing.
