What Customers Are Saying

Customers overwhelmingly praise this concrete crack filler for its simplicity and effectiveness on small to medium cracks. Most highlight the mess-free application—sprinkling powder into cracks and misting with water—with results described as invisible and seamless. Reviewers consistently note it outperforms alternative fillers like caulk, dries to a solid level surface, and requires no mixing. Some mention the bright white color doesn't blend perfectly with darker concrete, and a few report wash-out after heavy rain if curing instructions aren't followed precisely. Overall, most customers consider it the best option for hairline to half-inch cracks.

Happy salesperson recommended product

Would Recommend

Had to repair a crack on my back porch which had been repaired before but was unaware the product I had used was not for exterior application. The salesperson at the store recommended this product, suggested to let dry for 24 hours and to apply a primer before painting the floor. I am so happy with the ease of the application and the how well it fixed the problem. I can’t see where the crack was. Very happy with this product.

Was skeptical but works great!

Recently used this to repair my garage floor. My brother thought caulk would be the better choice but we ran out so we used this. This product looks more natural and blends in better than the caulk. I am going to buy another bottle of this.
