Filling Concrete expansion Joints

[LeeG]

I am grasping at straws here. A few years ago, I saw a thread on here that recommended a urethane caulk filler for concrete expansion joints. I have a sloped driveway, so nothing self-leveling will work. The recommended product was available at Lowes, (it wasn't DAP or Loctite brand). The material was very thick - as in zero slump. I would like to apply the same stuff to another slab, but I can't for the life of me remember what it was. I tried searching old threads, and nothing really rang a bell.

The stuff I put down previously has hardened to basically the consistency of a soft rubber (about like horse stall mats). It may have been SilaFix 1A, but that doesn't seem right either. Was definitely in 10oz caulk tubes.

Thanks,
Lee

I see your in the Phoenix Area, call Border Construction Specialties or Marvel Masonry they have the contractor grade of NP1 or NP100 you are looking for, not the stuff the Big Box stores sell. Limestone or Stone will be the color your looking for to match your concrete.

I used Sikaflex Concrete Fix, it was thick.

I started doing mine with a caulking gun. That got old in a hurry! Ordered an air operated caulk gun. Wow! Project went fast and no wear and tear on me!

I have a Milwaukee M12 caulk gun with both 10oz and quart capacity. Thanks for the responses guys. I appreciate it
