PC Products 70086 PC-Concrete Two-Part Epoxy Adhesive Paste for Anchoring and Crack Repair, 1.4 oz in Applicator Syringe, Gray

I don't know how this product doesn't have 5 stars. I sealed 7 8’ vertical cracks with two tubes. I have poured concrete walls with a brick design. Cracks ranged from hairline to 1/8”. I did not prep the surface much. Hit it with a wire brush and wet rag. Yo and you will get a u will need a heavy duty caulk gun to dispense it and your hand will get tired squeezing the trigger as it is a thick epoxy. It sticks to the wall and does not run at all. Wear latex gloves and spread it by hand across the crack. It dries very, very hard and I am sure is the same stuff the contractors use. Contractors quoted me $500 per crack. It has only been up 2 months, but no issues so far. I HIGHLY recommend this product at this time.

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.

Im a Locksmith and once in a while I need to drill holes in concrete. Whether its for door pivots or a key box I prefer using the screws and an epoxy. I don't want to be the cause of some leaks in the future or have something I installed come out at the wrong time. I don't use it enough to justify getting large tubes so I use these smaller tubes. So far I haven't had any issues whatsoever! Its super easy to use and holds really well!

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

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.

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.

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.

Very well satisfied with the product Used it to fill some cracks in a basement floor. Most were small, about 1/8" deep by several feet long. The large one was about 4 inches long and 1/4 inch wide and ~1//8 inch deep . Sealed perfectly. The Epoxy hardens almost rock like in about 4 hours. A reasonably good dispenser gun works well a cheap, flimsy one maybe not. Have to squeeze the dispenser gun somewhat hard but excessive pressure is not required. The Epoxy is about 11/2 times as hard to pump out than RTV silicone. Covers well1/4 inch by 1/8 by,1/8 by 8 foot easily. Seems to work better if the crack is deep enough for the epoxy to fill, not just smeared on top of the crack. Best to smooth out the Epoxy with trowel or putty knife it into the crack, do so immediately because it hardens pretty fast. The Epoxy would be very hard to smooth out once it fully hardens. After about 20 or so minutes it really started to harden.

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!
