This product, available in a convenient 6-pack, is specifically designed to tackle cracks in both indoor and outdoor concrete surfaces. What I appreciate the most is its moisture tolerance, which means it effectively seals wet or dry cracks. Whether it’s in my basement, around my pool, or on my walls, this foam is an ideal solution that I can confidently use. It’s great to know that I can maintain the integrity of my concrete structures with such an effective product.
