What Customers Are Saying

Customers overwhelmingly praise this concrete patch for its ease of use and effectiveness on small repairs. Most appreciate that it requires no mixing and spreads quickly with a putty knife, blending seamlessly with existing concrete and matching color well. Reviewers report strong results filling cracks, chips, and holes in foundations, driveways, and patios, with many stating they would repurchase. However, some note extended drying times and incomplete curing, particularly when applied too thickly, with occasional reports of shrinking or cracking. Overall, most find it ideal for DIY foundation and driveway repairs.

I’m band-aiding my house together

Would Recommend

I have a very old home. I used this product to fill some cracks/gaps/holes in my foundation and concrete pad outside my door. It does “sink” a bit as it dries, especially on horizontal surfaces which isn’t an issue if you aren’t sticking glass/ceramic mosaic pieces in it😜

Not for fine cracks-probaby ok on larger ones

Would Not Recommend

Used on pool deck cracks, putty knife smoothe, using wet knife as suggested. Difficult to hide even after palm-sanding and paint. May be ok on larger projects.
