PC Products 92507 PC-Xtreme Polyurea Elastomeric Crack and Joint Filler, 8.6 oz Cartridge, Gray

Q: Planning to use it for garage saw cuts prior to epoxy. Cuts are V shaped, so not sure backer rod will stay put. Did anyone used sand and what kind?

Hello, I used this on both saw cuts and hand cut expansion joints. I did place sand in the joints and 1/8-3/16 depth from surface. I used kiln dried play sand. Product worked great was able to roll a full tool chest over joint when epoxy floor coat cured. Used about 2-3 tubes per 22’ joint. Shaved flush to surface very easily. Be sure to prime before epoxy coating is applied. Very happy with product has been down a year and stood up to the extreme Minnesota winter and hot summer.

Q: Can this be applied vertically as well, to just about 4-6 inches high? I need to fill a vertical eroded mortar gap / crack in brick veneer. Thanks

No it cannot. Product is too thin to hold in place vertically. It has the same property as self leveling caulk.

Q: How many feet of standard garage contraction/stress joints will the 22oz tube fill? Im not familiar with cu inches.... thx

It’s been a while since I used this stuff but I seem to recall it will do about 10-15 feet.

Q: Can this be applied to a concrete floor joint before grinding/polishing the floor?

Yes, our concrete floor is 30 by 56 with expansion control cuts every eight feet. adter the PC extreme cured i used a sharpscraper to trim the excess, I sanded in several places. After we applied the floor coating, you can hardly seewere the expansion cuts are.
