Concrete Grinding Questions

[Augus7us]

Hey Gang,

Thanks to this site I'm going to epoxy my shop floor. I'm excited about it but my shop upgrade expenses have mysteriously grown uncontrollably since joining this site...

I have to rent a floor grinder, like most I assume, and around here they are ~$150 plus any fees. Because of that I would like to grind my entire floor in one go. The catch is that I can't epoxy my entire floor in one go.

I have to do the floor one half at a time due to space. Fortunately nothing is setup so I've got everything piled on one side. My concern is can I grind both sides, then epoxy the floor and let that cure for a week or so then move everything over to the expoxied side and repeat. I'm assuming I'll be fine but thought it best to double check. I really don't want to rent this thing twice.

Yes, you will be fine. Just keep the uncoated area clean. Vacuum well with a shop vac before you start and you should be good.

I ground my slab last fall, and couldn't get it coated before the weather got cold. But, I still needed to store stuff in my shop over the winter too. I laid down some thick plastic sheeting and tacked it to the wall framing to keep it from moving around. If you're concerned about things leaking, or making a mess on your freshly ground slab, you might be able to do something similar

Great idea. Kraft paper works well too.

Agree, no need to re-grind, paper or plastic as noted above is fine. The red paper they sell at home centers to protect wood and tile floors during construction works very well.

Thanks guys, I figured it would be fine but I thought I'd check with the pros here!
