What Customers Are Saying

Customers praise this product for its fast-setting properties and rock-hard durability, with most highlighting its ability to cure within minutes and prevent water intrusion on driveways and basement walls. Many find it easy to apply with a caulking gun when properly prepared, though reviewers emphasize the need to work quickly before it hardens. A significant drawback is the intense odor requiring well-ventilated areas and respirators. Some users report it sets too fast for larger gaps, and a few experienced extrusion difficulties or color mismatches. Despite these concerns, most customers consider it highly effective for urgent concrete repairs.
