Very hard to get out of the tube, broke my caulk gun. I had to give up since my hand hurt. Wish I could have returned them, but opened and tried two tubes before found out they are all probably like this.

This is a very small amount of epoxy. I needed to get more. But it did a great job.

This product is amazing and saved my garage floor from further deterioration. We actually park our cars in our garage. After 25 years of water dripping off cars, minor cracks began to expand. Filled in the cracks with PC-Concrete Two-Part Epoxy and the cracks are sealed water tight. The color of the epoxy differs from the concrete, and doesn't look the best. However, a simply painting of the garage floor would solve this problem. The stuff is thick, and by the end of the tube my hand was tired from using the caulking gun. I would highly recommend this product for anyone who wants a water tight seal of cracks in concrete.

I had a 6 foot long crack along my finished basement floor. While the crack was mostly thin, there were a couple of spots along that crack that if I poured my latex floor primer, it would drain into the foundation indicating a spot for water to come out in the event the water table were to raise. I was hesitant that anything that comes out of a caulk tube would hold up the hydrostatic pressure it would need to combat over time. After grinding the crack wider and filling it with this epoxy I let it sit overnight and checked it the next morning. Sure enough, this epoxy hardens tougher than concrete and taking a thick scraper to it in a test spot I created made me very comfortable that this is a permanent fix solution. My only gripe is how hard it is to get out of the tube, and that you only get about half of a full amount of a regular caulking tube out of it. If you have more than a 12 foot pinky-width crack to fill, you will need to buy more tubes. Still giving this 5 stars because a dry basement is worth more than $20 and I would recommend it to anyone in my situation.

After almost a year of use, the repair in my cinder block wall is holding strong. You have about 2min of working time you need to spread it a little. I used a 25:1 caulk gun, so it was really easy to apply.
