What Customers Are Saying

The concrete crack filler appears to have mixed reviews. Many customers found it easy to use and effective for filling cracks, with a nice concrete-like appearance and durability. However, a significant number reported issues with the product not drying or curing properly, leaving the filled cracks sticky or soft. The performance seems inconsistent, working well for smaller cracks but potentially less reliable for larger or more challenging concrete repair jobs. Careful application and patience during the curing process are recommended.

I had a contractor recommend this and wow it works great. The coloring is perfect and blends nicely with the existing cement/mortar/grout.

Pool-deck cracks

I have used many products over the years trying to get rid of the cracks on my pool deck. This time I used a syringe that was designed for art projects. I filed just inside the crack as I had learned on my first attempt on my mom’s pool that this stuff spreads and doesn’t come off easy. Some spots sank and I hit them again. Not long after filling and painting, we had three nights of freezing. There is no sign of any movement. Time will tell over the summer with lots of pressure washi...

Not Impressed

Would Not Recommend

Sank into the crack and dried. Then it split (inside the crack) making the crack more narrow and impossible to fill except over the top with more, causing a ridge. Attempting to smooth it, just dragged it out again after the first attempt.

Perfect for sealing cracks in concrete

Would Recommend

The product thick and closely matches the concrete color. I used a plastic scraper to smooth and press more product into the cracks.

Need lots of drying time!

Would Not Recommend

Disappointed - this was supposed to be dry in a day or 2 but I had rain 4 days after it was applied and the caulk got soft/mushy and sank into the crack! I had filled a different crack that had over a week of dry weather and it held up to the rain.

Slab concrete sealer.

The concrete crack sealer flowed nicely into the smaller cracks and larger. It does really seal nicely. It rained a few days after I filled a lot of cracks and where I sealed to water did not leave a trace of seeping like those that I did not get to seal yet.
