A smooth 900sqft concrete slab has been poured and is awaiting the construction of my woodworking shop.
There are always better, more expensive ways to approach each step of the new shop building process, but the floor is not one on which I plan to spend a lot of money.
I never plan to drive a car into the shop (though technically I could), or riding mower or anything like that.
Most of my heavy equipment is on casters.
As I see it, the options for floor finish are expoxy, paint, or some other kind of sealer.
I’m currently thinking white paint, making it easy to find tiny parts that are dropped.
Does anyone have specific product recommendations, or other guidance, to help me make good choices here?
Thank you!

I’ve used various products and i would still suggest the 2 part floor epoxy, followed by a sealer and polish. Especially before you start putting anything in there its easy breezy. You will spill stuff and drop things and it will hold up better than the floor paints if done right. You can pop glue off easy and wipe up chemicals usually without damage. A new white floor you will be able to find parts easier, until the second day when there are shoe scuff marks and other marks all over the place.

Just keep in mind new concrete needs time to cure before any top coat you choose to use.

This stuff. It ain’t cheap, and it smells when wet, but it’s been on my garage floor for a year, 100 yo concrete, and I can’t hurt it. Hardly any prep involved with new crete.

White gets dirty fast so I am not sure I would go for that but perhaps a light grey could be an in-between solution. Having said that you may want to just put a clear sealer on it to make sweeping easy since you will already be in the grey color range anyway.

Dont use the decorative confetti crap they give you. it makes it impossible to find stuff on. I only did it on one 20×20 section when I first began.

At work we have an epoxy floor it held up nicely over the years. I would second the light gray over the white because white glaring up at you all day would be hard on the eyes.

I had epoxy with the little plastic confetti stuff. Loved it for traction. Hated trying to find dropped screws and washers on it. When I got my shop done here in Santa Fe, I was going to get epoxy over the concrete in the motorcycle garage side, but the contractor flaked out, so I’ve still got naked concrete.

The one thing I wouldn’t do is get epoxy with nothing in it. I’d probably get the sanded stuff, as spills on epoxy are pretty dang slippery. Also, I would prefer gray to white for glare. But I’d also look at light yellow or other pastel choices. Gray seems too likely to hide small parts.

After a lot of evaluation, I went with tile. The inexpensive tiles at HD were on a really good sale and I was concerned about the longevity of epoxy, especially after reading the various reviews. Sounds like surface prep, etching, and cleaning make or break the epoxy floor coverings.

One of the folks I work with painted their basement with the fancy version of Rustoleum metallic epoxy after their basement flooded. It took 4 people 2 days. The first day was spent cleaning, etching and prepping the floor. Day 2 was spent with one person rolling the paint on and 2 people taking care of the edges. The last person made sure the epoxy was ready to go the rolling didn’t have to wait as well as spreading the sand. Apparently, it sets up FAST and if starts to dry and you roll over it things get screwed up. I saw the finished pictures – WOW it looked great. I haven’t heard if they had any problems with it popping.

I need to do this in the shop and in the main garage. I might wait to see how it works for you.

Clear sealer, after the concrete has cured completely. + 1 for no paint or epoxy. There is a concrete stain available that soaks in and won’t peel off. Also easy to repair a chip or ding in the floor without buying a whole epoxy kit to use a brushfull.

I’m a terrible finisher. My floor gets painted over time. :)

Sealing or painting is really a must to keep the concrete dust out of your tools. Use anything you can afford.

Fresh concrete tends to be dusty in its natural state. And yes the dust leaves a layer of abrasive dust for the first year or so. Not to mention concrete is porous and sealant will help it not to wick.

Concrete dust? Are you wearing sandpaper on your shoes? The bottom of my boots are way softer than the concrete floor.

Well I had to look that up and there is such a thing as concrete dust. As far as getting in to my tools after 30 years of no damage I’m not going to worry about it. So I going with my original advice.

I’ve been on unfinished concrete floors and there’s a nails-on-a-chalkboard feel to them for me personally. I’m definitely going to finish with something!

Simplest option on the table so far looks like “Eagle Natural Sealant” or similar, at Home Depot: a $90, 5gal can covers 1000 sqft and I don’t have to mix anything.

Good points about white paint being a bit too glaring as well as too prone to scuffing. Perhaps a light gray glossy paint…
