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 impressed. quick cure, very easy to work with, very strong. and I might mention that buying the caulking gun was well worth it. this gun is one of the best made guns I have seen. highly recommend this product. pls. do keep in mind, like many things, the better the prep work, the better the product will work.

used to rework a storm shelter installation, that the installers 2 part epoxy never adhered to the concrete floor in the garage, or to the bottom of the shelter. Roughed up both surfaces with diamond blades in a multi tool. The epoxy is quite sticky when mixed, had decent working time. I taped off the floor & storm shelter, mixed batches equaling approx 1/8th of container. Then troweled in off a piece of sheet metal I mixed it on, making sure to swirl it on both surfaces prior to gap filling. My application a bit different than normal uses, as the storm shelter was in place & weighs approx. 4,000 lbs, with some gaps 1/4-3/8 of an inch, due to garage floor irregularities. All said it seemed to bond to both surfaces, easy to trowel in using a margin trowel, , and has cured very hard with in the 24 hrs stated . As far as strength/adhesion? Won't know unless it gets Tornado tested. I do believe it definitely enhanced the strength of the anchor bolts in to the concrete. Got way more product at way less expense than purchasing in caulk tube form... the 2 tubs did interior & exterior perimeter of a 4x6 ft shelter

I used this product to repair a blew out portion of my pool deck where a brass recessed pool cover anchor went. I applied the products around 6pm and waited over night to allow it to set and fully cure. The next morning it was rock solid and ready to go. It's been 2 months now and the anchor hasn't budged. This product may be expensive but I'm telling you, you mix it right in the beginning and apply it correctly, it will not let you down. This stuff is no gimmick, it's the real deal

Worked great and cured just fine in lower temps. Holding up well to secure my concrete anchors that had pulled out of the holes.

To start I rarely ever write reviews. Probably did three in my life. This product worked so well I had to for this one. Approximately 12 years ago we developed a foundation crack in my poured basement wall. Over the past 12 years the wall would leak very little only with large amounts of rainfall. I have tried everything from hydrolic cement to wonder products like Flex Seal. Nothing worked. There is no way to access the crack from outside due to an inground pool and concrete walkway. I looked at other options with products you inject into the crack. Only problem is the lower portion, where most water comes in, is a hairline. I called two contractors to look and cheapest price was $1,000.00. I was told only way was to grind and chisel crack wider then use some super duper epoxy. My son asked his HS shop teacher for ideas. This product was his suggestion. First thing i did was take a diamond blad grinder and cleaned the area well. I also ground a small “U” shaped channel along the crack. The problem i was running into was active water seaping in. I fixed this with a propane tourch. Put flame into the crack and heated it enough to stop the water fot atleast 10-20 minutes. After knowing this would stop the flow the last step was to acid wash the area. This removed all the chalky residue from the area. One more hit with the torch and inmixed the two compounds. It was a bit thinner than I expected but still went on with little issue. That was two days ago. It has rained twice since putting it in and no leaks. Solid as rock. I included three pictures with this review. The first youu can see the brown on the wall. Thats mud that was seeping in the second was after i ground the crack down and put score marks to help the epoxy grip the wall. Last one is finished product. I am extremely pleased with this product and it worked better than expected.

While this is very strong and probably works wonderfully on flat surfaces, it is very runny and does not do well on vertical surfaces. I spent 20 minutes having to keep pushing it back up the wall as it started to sag. Additionally, I tried to apply it to a slightly damp wall, and it is so hydrophobic, that it just slid off and wouldn't adhere. I don't think that any of it is still on the damp wall.

Works like a charm. You will definity need a higher ratio caulking gun to dispense the product from the tube. I used backing rod/foam to create approximately 1/2 inch depth for a long step crack and I still had to order more product. But the product really is good for its intended purpose.

Very good

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.

slow to arrive but fine apart from that!
