Background:
I'm hoping to epoxy my 1000 sq ft garage this weekend. Started the build nearly two years ago so concrete is fully cured and I've kept all vehicles/work out of it during that time so there on no stains although there was a fair amount of dirt from the construction process. I started by pressure washing the floor. Then hosed it off with a water hose and scubbed it with a brush and simple green and rinsed again. Then acid etched it. After the first etch, I didn't think I had enough profile so I etched it again. Then scattered three big boxes of baking soda around, scrubbed it again and rinsed. I then filled the saw cut and two small cracks I ground out with sikaflex. Let sikaflex dry 4 days and sanded it smooth. Then pressure washed again.
My problem is that I have maybe 2 dozen low spots, chips, spalling (not sure what to call them) no larger than the size of a half dollar. They are less than 30-40 thousanths of an inch deep. I suspect they may have even been caused by acid that sat in low spots in the floor for too long. My question is do I need to fill these in? And if so, what do i use? Or would the epoxy hide them good enough? I plan to use two coats of Devoe 224 followed by a top coat of 379. I don't want to be too **** and end up trowling the whole floor flat, but would also like to have a nice flat finish when I'm done. This almost has me re-thinking my decission to not use flakes. Thanks for any input.
