Epoxy garage floor before or after drywall?

[jmarkwolf]

1. Before drywall means that a lot of foot traffic and ground in drywall dust and mud etc., into my nice new concrete, that will need to be cleaned off of course.

2. After drywall means that drywall dust and mud will need to be cleaned off the epoxy afterwards. Anti-skid additive might complicate this process. Mud might not come off easy.

I can't believe that trying to tape down paper or tarp before hand in either case, will hold up due to dragging ladders and mud buckets around etc.

Any pearls of wisdom?

Depending on how smooth the concrete floor is will determine how much mud droppings, and dust will adhere to the concrete. My garage floors are power troweled to a extremely smooth finish, and after the drywall was installed and plastered, everything cleaned up fine with a scrapper and a broom. If it were a rough surface, it seems that they never come clean, no matter how much you sweep them.

Grind your floor post drywall and painting, coat the floor last.
Touch up your wall paint post floor coating.

I wonder if the drywall guy would have the same opinion. That's probably the way I would do it with dry wall. Dry wall first then Epoxy

I'm having the same concerns with my interior corrugated steel walls. In this case I'm electing to Epoxy first and put the steel up later. The corrugated panels need to be 1/4" off the floor and getting in around and under the corrugations would be too difficult. Plus the steel doesn't make dust.

I'm new to epoxy floors but I'm an above the DIY level construction guy, too. My two cents is this: you're on track with the corrugated last. Not only trying to paint under the corrugated tin will be a problem, but do you really want to be worrying about the tin while you're also "worrying" about the epoxy floor going on right, etc?

jmarkwolf - I'm in line with Scotty from Legacy, do floor after drywall.

Regarding finish, unless you're set on your drywall guy doing your finish wall coat for you, I would recommend they apply the primer coat, which is common practice, then you do your epoxy floor. Then finish paint your walls after epoxy is on the floor.

The two advantages that I see are you will have your floor color on the floor which will finalize the wall color choice, since the floor is a whole lot of paint area, and the white primer walls will help you see the epoxy bumps on the wall so you can wipe them up. Also, latex drips should wipe right off the epoxy, but you'll probably use drop clothes anyway, so that might be moot.

Piggyback question: Should I epoxy first and then install lift? I'm concerned about not having epoxy under the lift - and it would be a lot easier to epoxy with a lift in the way. But I am wondering if I may scratch the epoxy with the heavy lift.

Also, I am behind on the electrical, so I would have to do the walls after the epoxy.

Thoughts?

I would install lift after epoxy if it were my garage. I like the idea of having a full and continuous epoxy membrane over the entire floor.

If you're hiring drywallers, you might want to ask if they can be more careful of floor or cover the floor with sheets of cardboard or something. You also might want to wait a couple of weeks to allow epoxy to cure. I've read that they cure in 7 days but being sure will not hurt.
