No. Our top recommendation for sealing brick, concrete wall or floor is our Green Building Supply Penetrating Concrete Sealer because it waterproofs and preserves in just one application. Plus it comes with a 15-year waterproofing warranty. The surface must be clean, dry, neutral pH and porous. It cannot be painted or previously sealed as it will not absorb our sealer. It's always best to get a sample and test before applying everywhere. Samples can be purchased for $9.95 which included the cost of shipping.
