  • Great product but do not attempt this without at least one (two preferred) helpers
Awesome product but cures very, very quickly! Do not attempt to use this without at least one other helper (as the instructional video suggests) to aid with the second application of sand and scrapping before full cure. Once you start, you really need to keep going to ensure the nozzle doesn't plug up (two minutes MAX if not dispensing). Have all of your cracks prepped and all materials ready to go before you start. Would be nice if the kit came with another application nozzle or two. I am very satisfied with the results so far - a full season will tell if it's works as well as advertised. ... show more

  • Quality product
CrackWeld Pro floor and crack sealant is a highly effective product in sealing concrete basement floor cracks. The product was very easy to use, with clear instructions for use. Also, the product required little time to apply and the clean up was easy. I would recommend this product professionals and DIYERS. ... show more

  • a useful product
This is good product. I encountered a problem because of the packaging. The instructions state that you should first remove the protective top and then tap the cap downwards with a hammer to break the seal. The openings from this action ( on one occasion ) were too small to allow the proper placement of the backflow restrictor. I resolved this problem by slightly enlarging the openings with a small knife. I then followed the remaining instructions without any further incidence. ... show more

  • Great product! Super easy to use.
Awesome product! Very easy to use. Second set of hands does help a lot. Cures quick but not too quick. Plenty of time to get it done. Only recommendation is buy extra sand. Highly recommended.

  • Mediocre results.
I prepped the crack by opening it up with a diamond V shaped grinding wheel followed by a sst wire brushing, then a very thorough vacuuming. Installed the product as directed. The temperature was 71 degrees F., and the RH was 42%. I filled 45 feet of 1/16" crack lines. After drying for 3 days, I crosscut the cracks (50 time) to install rebar. Every crack fill only penetrated 3'16". This is not even close to the advertised results. Product is way too thick to penetrate through crack. ... show more
