Rustouleum Patch and Repair Sanding

[Harris360]

I just applied some patch, and repair epoxy stuff from Rustouelum, and nows it been over 2 days. I can’t get it sanded down using 50 grit at all, I’m just tying to level the patch off to the same level as the concrete. Any suggestions?

Yea I used that and regretted it because it took an amazingly long time to grind down.

I ended up using a coarse grit flap wheel on a 4-1/2" grinder and spent hours sanding a 3 car garage floor. I thought I was doing the right thing by filling in all the small dips and holes in my floor, yet it took forever to get smooth. Even with that, it was hard to control and I ended up scratching up the floor anyway and creating more divets with the flap wheel.

An epoxy is very hard and can be grinded with a cup wheel, just be careful as they can be aggressive. Vacuum well prior to coating.
