PC Products PC-Masonry Epoxy Adhesive Paste, Two-Part Repair, 128 oz in Two Pails, Gray 71120

4/3/2018 update: still holding up strong after a few years and harsh winters. Took another pic on a rainy day, that's why the concrete looks darker. A bit pricey but this stuff holds a strong bond to my existing concrete like nothing I have ever used before. This stuff seems to stick like a Quad brand caulk, but this stuff dries hard within hours. Too be so gooey, could not believe this epoxy dried strong and hard like concrete. Dries light gray, I threw in some sand to tone it down. This stuff doesn't even shrink or sag. Harder to work with than hydraulic concrete, but this stuff seems to be more of a superior product. Repaired some hair line cracks and broken driveway and foundation, glad I was able to sand down high points.. I can't wait to see this next year, the way this stuff bonded I would almost think this will last for years. Clean up is a bit messy like adhesive or oil base products , but this has to be my favorite concrete product so far. This stuff doesn't appear to have any visible cracks, I would almost think I will be crack free for a long time to come....only time will tell. I have only worked with epoxy products 2 other times and they have lasted years and counting, so no reason to think why this wouldn't last for years.

This works great. I used it on a really old really big 3 bowl waterfall type birdbath feature in my yard. The rim of the bowls were starting to crumble and I wanted to repair them because there aren't these types of water fountains anymore and any that are even half the size are really expensive. I like that this product is nontoxic since birds drink out of the fountain. The video in the reviews section really helped because it showed how to use alcohol to clean the putty knife in between dipping into the containers because if the two materials make contact with each other they begin to harden quickly. I cut a cardboard tube from an empty roll of paper towels in half and used the arc shape of that to shape the product onto the lip of the fountain bowls because they were originally rounded around the lip before they began to crumble away.

Excellent bonding, easy to use, sturdy repairs.

I have been using masory epoxy for different projects big projects and this one is by far the best one I have ever used. It’s very thick but adhere extremely well, it’s very easy to grind down with any surface grinder and because there is sand in the mixture it make it almost the same as the concrete it self . Also the bound is very impressive. The only down point is the price , it’s very expensive to bring this in Canada , but worth it.

Expensive but was able to stretch it by adding pea gravel (Home Depot) to the epoxy. I was able to smooth out the surface with a trowel. I was able to polish down any rough spots with a belt sander. Used this to patch holes and uneven surfaces in my airplane hangar asphalt floor. Absolutely no chipping or cracking after driving vehicles and a 5500 lb. airplane over it many times.
