People Also Ask

BASEMENT SEALER™ is designed for concrete, cinder block, masonry, brick, and other porous wall surfaces. It can be used on both interior and exterior basement walls as well as above-grade or below-grade masonry walls. It adheres well to properly prepared porous surfaces and many previously painted masonry surfaces, making it an excellent choice for protecting and waterproofing basement walls.

BASEMENT SEALER™ is formulated to waterproof walls against positive hydrostatic pressure, meaning water coming from the outside toward the wall. If your basement has active leaks caused by negative hydrostatic pressure (water pushing through the wall from behind), we recommend using BASEMENT SEALER PRO™, BASEMENT SEALER PROTEX™, or BASEMENT SEALER CLEAR PRO™, which are designed for those more demanding conditions.

Yes. BASEMENT SEALER™ creates a durable waterproof barrier that helps reduce moisture intrusion—the primary cause of mold and mildew growth. It is also formulated with environmentally friendly mildewcides that help resist mildew on the coating surface, helping keep basement walls cleaner and better protected over time.

In most cases, BASEMENT SEALER™ serves as the finished protective coating and does not require painting. If you plan to apply another elastomeric coating or paint over it, be sure the sealer has fully cured and verify compatibility with the finish coat. Following the recommended preparation and application instructions will provide the best long-term performance.

BASEMENT SEALER™ – Ideal for general waterproofing and protecting concrete and masonry walls against positive water pressure. BASEMENT SEALER PRO™ – Designed for more demanding waterproofing applications where higher hydrostatic pressure resistance is required. BASEMENT SEALER PROTEX™ – Features a textured finish while providing excellent waterproofing and resistance to negative hydrostatic pressure, making it a great option for leaking basement walls or surfaces with minor imperfections.
