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

We repaired a few cracks and a major break in a solid poured concrete retaining wall. Using deeply drilled holes we used it to anchor the rebar on both sides of the crack then as filler up to the soil line. This review is after almost a year of the repair and its doing great, no separation or leaks. I am very happy with it overall and it was worth the cost as it saved me 30,000 by allowing me to fix it on my own and probably in a better method than the professionals would have used.Frost heave in clay is no joke in the North and this stood up to it.I will be buying more to do the other broken retaining wall this year.

I bought this product after about an hour of online research of different brand epoxies. A few weeks ago I poured our new cast-in-place concrete countertops using Quikrete countertop mix from Lowe's. The concrete bag instructions say the forms can be removed after 18 hours. I waited 24 hours before removing the forms but I should have waited longer-- it wasn't ready. I found that out the hard way when a 6" chunk of concrete broke off the front edge corner of my brand new counter. DANGIT. Luckily, the chunk broke off whole and clean, in one piece. It was a perfect fit when pressed back into place, no chips or small bits to mess with. I used this PC epoxy to reattach the broken chunk following the simple instructions on the package. I held the chunk in place by hand for about 25 minutes to let the epoxy set, then taped the chunk in position to hold it overnight. The heavy chunk of concrete is now SOLIDLY reattached and I'm pretty sure if I whacked it with a hammer, the concrete around the repair would shatter before this epoxy lets go. The gray color is a close match to the raw, un-colored concrete and the repair seam is thin and hardly noticeable. I'm confident that once the concrete is stained it will be nearly invisible. This is good, strong epoxy for repairing broken concrete, not just for filling gaps and cracks but also as an adhesive for actually reattaching chunks of concrete. Oh, and when I called PC Products to ask a couple questions before I bought this stuff, I got an actual person on the phone who was very knowledgeable about the product. Excellent.

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.

Bought this to repairs some cracks in foundation. Works good, adhesive is good and forms a strong protection, and is easy to use. My one complaint is that I bought this and a 3 pack of the tubes. I found all of the tubes to stop at about 2/3 of the way. A lot of money for not filling the tube all of the way.

The 2.8 oz small quantity epoxy requires an expensive $50 applicator tool in order to use the product. This is not mentioned anywhere in the description. The seller also does not accept returns. I contacted Amazon support and a refund was processed due to the lack of full disclosure in the description. This may be a fine product but it is not a good solution for anyone who has a one time fix and only needs a small amount of epoxy as it will cost about $65 by the time you have everything you need to do the job.

Stronger than I expected. Sets fast but waiter 24hrs to to be sure.

1 stall garage was severely cracked and pitted every where. After a few days of grinding, washing and etching the floor I put down 106 ounces (3 tubs) and also 3 caulk tubes of the same stuff in tube form. Next step is 2 coats of epoxy paint, sprinkles and 2 clear coats of epoxy.What I like is this stuff gets really hard. I’m hoping it lasts a long time without busting up. After spending days reading reviews and watching YouTube videos on many products I have the most faith in this product for a long lasting beautiful repair.What I didn’t like is the price. $300 in just concrete repair and another $300 for the epoxy coatings to go over this for a one stall garage. I knew the costs going in. If it works I’ll be thrilled, if it doesn’t I’ll be kicking myself.It would take mad skill to have a completely smooth finish over a large area. It’s like troweling honey. If you over work it to make it really smooth you will probably make it worse. I settled for slightly bumpy anti slip surface as opposed to sanding after. Good luck getting this off your trowel.Update: after 6 months and 50 below wind chills, my floor still looks beautiful. First pic is this epoxy. Second pic is the before. 3rd pic is this epoxy painted gray with 2 clear coats over top that.
