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.

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.

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.

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.
