Driveway Caulk

[moab_cj5]

I want to fill the seams and cracks in my driveway with sealant or caulk. Anyone know of a good product I can get to fill the seams to prevent weeds and ants, and help keep water out of the expansion joints?

We've had good luck with Sikaflex and foam backer rod.
Broom the joint out really well and stuff the backer rod in and then fill her up with the Sika.
You'll need the larger caulk gun.

I’ve done the sikaflex and sprinkled sand on it for texture. It works and looks great.

Depending on what size backer rod you need, I have many feets leftover from using it in my shop.

I need all sizes. I have large joints (an inch?) to small joints. I also have a yuge driveway so I'll take what you have. I need a bunch!

Definitely don’t skip the backer rod.
