The past few days have been a lot of work. Friday afternoon I rented a diamond grinder from Honeyman Rent-All and spent several hours grinding the floor. I had to completely empty everything out of the garage into the driveway and yard. Of course it all had to go back inside when I finished around 1 AM.
The diamond grinder was pretty easy to use. It’s a little noisy, but not bad enough to get the neighbors complaining. The hose connects directly to it to keep water flowing to keep the heat and dust down. I was able to do all of the grinding, rinsing and squeegee-ing in about 4-5 hours.
Saturday I rinsed the floor and used the citric acid from the Rust-Oleum epoxy paint kit. Probably unnecessary, but I had no other pressing need for two bags of citric acid. It also cleaned up the inch or so that the grinder couldn’t get right up against the wall. Then I spent another hour or two rinsing the floor, followed by the squeegee. After the second round I used the shop vacuum to get it as dry as possible. It’s looking pretty darned good right now, so Sunday will be painting day. I have prepped both sides, but the third bay will have to wait. I simply can’t empty everything out of the whole garage for a week.
