PC Products 72561 PC-Concrete Two-Part Epoxy Adhesive Paste for Anchoring and Crack Repair, 8.6 oz Cartridge, Gray

This is good stuff! I used it to repair a disintegrating front step. After it cured it was quite tough, and had a smooth, glossy grey texture (don't expect it to look like concrete). A hint: Work quickly! It starts out fairly thick, and on a warm day you may only have about 10 minutes before it gets difficult to work with and won't level well.

Very good

We used this to patch a network of cracks in our concrete garage floor, and a crack in our house's foundation. We went through several tubes of this stuff. The tube contains one half adhesive and one half hardener -- the tube is not just half full as some people have complained. It is half-full of a gray substance and half of a white substance. As you squeeze the stuff through the special nozzle, it mixes to a uniform pale gray. Squeezing the stuff through this nozzle is no easy feat. However with the little determination and perhaps a pair of channel locks it can be done. We did this as a team. One person squeezed the channel locks. A second person guided the nozzle, which as you can see is an equal length to the caulk tube so it's a bit unwieldy when aiming at narrow cracks. A third person used a spackle knife to smooth out the epoxy and fill the cracks before the epoxy set up. The result is a network of pale gray lines cross the garage floor, but they are hard as a rock and the floor is as good as new structurally. We did the same thing with the foundation crack, but since it was vertical unlike the floor, getting it smoothed out and completely filling the seam was a bit trickier. We are very pleased with the results, especially since we really didn't clean the garage floor before exopying it. (okay, we didn't clean it at all--except to sweep away loose stuff.) A bit of advice: make sure you don't get it in your hair.

It's really amazing epoxy adhesive. Easy to use. So strong that might stop an elephant. I fixed a 60mm 12mm Dia Fe500 iron rod in a hole with this adhesive.Out of 60mm rod only 35 mm rod was outside the hole. After 12 hours we bend this rod without a small crack in joint. It makes my many tasks simple. Now it became a necessity because it makes so strong bond beyond one's imagination. I recommend it to all my colleagues. Thanks.

One of the best products I’ve used yet. If you follow the instructions. You’ll have no issues. It spreads and Fills really easy. Drys harder than concrete. If you’re fixing stuff around the house. Or out at your favorite spot. You’ll love this. It’s not temporary though. Once it sets it’s not coming out.
