PC Products PC-Xtreme Polyurea Joint Filler, Concrete and Blacktop Sealant, 22oz Cartridge, Gray 96000

Simply put, this product does exactly what it says it does. I used 21.2 oz containers to level control joints in my basement floor so I could epoxy over them. I read several reviews that stated there were soft and gooey spots. I have to believe they did not follow the directions. This is a two part compound and if improper mixing occurs (for any reason) it will not cure. So READ AND FOLLOW THE INSTRUCTIONS!!All five tubes I used filled 300 feet of control joints at 3/8”-1/2” deep. Product was shaved smooth with the surface of the concrete about 45 minutes after application.

Two pieces of advice. Read instructions under label, follow the directions to the letter for the best outcome. Get extra, the tube only holds about half the tube with product. It does expand a small amount, but its not viscous so make sure you are filling an area with a barrier at the ends of the joint you are sealing.

The product works well and is easy to use, that is until you receive units without nozzles. Had 50% without. Needed to complete a return only to be shipped more without a nozzle. One might consider buying from another seller.

Filled 1/4" concrete control cuts and looks really good and seems to be very durable. Color is not as light as I would like, so if your cracks are not straight control joints I would think it would look ugly in contrast with your concrete. Also, don't use a standard 10:1 thrust cheapo caulk gun unless you want forearms like Popeye, the mixing of the two parts is very hard to squeeze through the mixing tube. For my next job I'm getting the heavy duty PC products gun that has 26:1 thrust, and this product for almost 400 ft of cut. —Update: the higher thrust gun made it very much easier.

The good is that when it applied correctly it worked very well.I used multiple containers of this stuff and in 3 out of the 4 times there was a problem with non-curing sections. Followed the mixing directions carefully.The specific recurring issue I had is that when laying down a line of the filler, random spots the filler would not harden. My guess is that there might have been a bubble in the hardener tube or that it was feeding unevenly. You could not tell visually that these sections were not mixing correctly. So after the install is complete and dried I noticed my shoe smearing some areas. Even after multiple days they would stay wet.Contacted the company and they said only option is to scrape out wet areas and re-apply.If you explore youtube you will find many installations of polyurea doing the initial lay down of filler and then using a hand scraper cut off the excess. I tried this on one section and while it worked the cut wasn't very clean so visually the surface was not smooth. It is hard to tell when the optimum time is to try and scrape because the working time if very short and you need it somewhat hardened but not too stiff.I hand much better luck taping the sides of the joint, putting in the filler just barely overfilled and then quickly skimming the top of the joint with a putty knife. This gave a really clean look. If you go this route you need to get the tape off relatively quickly. In my case at 65 degrees anything over 10 minutes made the tape hard to remove and the filler wanted to pull off with the tape.Summary: Once on and cured looks like it will do a good job. Pain to install and doubly painful to have to touch up sections. Also because the double cartridge needs a mixing nozzle even if you have leftover no easy way to use remainder without another nozzle.

This stuff is incredible for filling cut control joints in concrete. It formed a tenacious bond with clean concrete and self levels nicely, but work FAST because it sets up in under a minuit! It can be trimmed with a razor so you are left with a nice looking flush, flexible and sealed control joint that won't catch dirt or creeper wheels. I'm pretty sure this stuff is bombproof after curing, polyeurea is tough stuff! The tube/mixing nozzle is very user friendly and easy to use.

Ordered what was pictured had it sent next day had a time sensitive application it had to be used for,product arrived on time with no mixing spout,now I have to reschedule and wait for the spouts to get here,my takeaway is this,don’t picture the product with the spout if that’s not what’s going to be delivered,or increase the price of the product to include the mixing spouts,very frustrating

After using 2 different contractors to try and fill up the extra anchor bolt holes and having them fail at the job, I decided to do the repairs on my own…I called the manufacturer of PC Products, discussed my issues before ordering the product to get specific instructions and expectations…PC Concrete has exceeded my expectations and works perfectly…20 minute work time and compete curing in 4 hours and ready to paint…used it in my concrete oool apron where the previous owners red rolled the anchor bolt holes for a new cover and left 17 empty bolt holes in the apron which was unsightly and a cause of standing water for the mosquitos…I did use bottom filling technique but the product did contract somewhat after curing so I topped up the holes and used a dry brush to stipple the product after about 10 minutes to feather it out to blend in with the concrete finish before painting…amazing product…I cannot say enough good things…
