I had my garage floor slab saw cut and want to fill the grooves in with
caulking prior to framing over it. What should I look for in a caulking
material that will last and can have a sealer/epoxy floor paint applied
over it as well? The grooves are 1/4" width and about 1 3/4" deep.
There's about 230 linear feet to fill and I figured just caulking in
the top 1" of the groove to where it's flush with the surface.
You can use a backer rod to fill in the joint to within 1/2' of the top
and then fill with a quality urethane caulk like Sonneborn NP-1. You
can still apply an epoxy (100% solids)over the floor. For instructions
on how to install an epoxy garage floor go to
Hope this helps
Excellent advice. For this install, you might consider SL-1 (same
stuff in a self leveling formula).

If the product suggested by the other posters is not available, HD (in
SoCal) carries a SIKA product that is a self-leveling crack sealer
that is perfect for the job, use a backer rod to control fill depth
