Default Epoxy Floors

Funny... a few years back I was visiting Reggie Jackson's
shop and he was mopping his floors ... 69 z28's
parked all over the place... he said the place was a mess
I guess he could have used one of Charlie's machines

The more epoxy floor covering quotes I get, the better polished concrete floors look to me...

I think I can see where the Lotus was parked in Charlies shop.....


A couple things to think about Lance ---- With "coated" floors -- if you drag anything on them -- you know what happens - if you do any metal cutting or welding -- they get burn marks....

They still look better if you do AT LEAST two coats of clear..... That's what I did in my shop and in my home garages (5 car).

In a "working shop environment" -- go with Charlies polisher.... you'll be happier.

So Charlie, who did you have polish your floors for the first time?

At the home show last weekend I asked every epoxy floor guy there if they polish concrete also and only one said he did...then quoted me $3.00 a foot which was more than a couple of the epoxy quotes I got.

Upon further review, he was quoting polishing the floor, then putting a clear coat sealer on top of it. I asked him about leaving the sealer off and he mumbled and said he'd have to ask his boss or something... So I walked away.

I use Armor Garage and been happy with it , I do re coat some with just the top coat once a year or so . Some of it gets more than just a car parked on it and for the $$ I like it. I think it was like $800-$900 for a kit to do 500 sqft , you can get it cheaper without the kit ( roller,acid,mixer ,base,top coat and misc.)
Forgot to say it's a two part Epoxy and the prep. is the hardest part .

Got my first quote for just polishing the concrete floors, two different options.


Scope of Work – Polish

-perform 30 grit diamond grind in order to expose salt and pepper aggregate

-patch minor cracks, joints and spalls using a cementitious repair mortar

-perform 80 grit finish grind

-run 150 grit transitional tooling

-hone concrete with 200 grit diamond impregnated resins

-apply clear penetrating sealer system

-polish concrete with 400 grit diamond impregnated resins

-polish concrete with 800 grit diamond impregnated resins bringing concrete high shine

-NOTES: Entire area is to be done in one mobilization taking 3-4 days during normal, daytime, weekday hours. Entire area is to be free and clear of all equipment, material, debris and other trades. Proper lighting, 110v/20 amp power, 208v/50amp/3-phase power, water and access is to be provided by others.



Price: $3.75 per sq. ft.



Option – Grind and Seal

-perform 30 grit diamond grind in order to expose salt and pepper aggregate

-patch minor cracks, joints and spalls using a cementitious repair mortar

-perform 80 grit finish grind

-apply clear solvent-based acrylic sealer

-NOTES: Entire area is to be done in one mobilization taking 3-4 days during normal, daytime, weekday hours. Entire area is to be free and clear of all equipment, material, debris and other trades. Proper lighting, 110v/20 amp power, 208v/50amp/3-phase power, water and access is to be provided by others.



Price: $2.30 per sq. ft.


Same guy quoted me $3.69 per sq. ft. for a full chip epoxy coat with 3 coats of Polyurea on top for comparison.

Just got back to this thread. I did not have my floor polished. When I had it poured they simply did a smooth finish. That is when you see the guy riding on what looks like a spinning hovercraft giving it a smooth finish. It has gotten shiner over time as I scrub it.

Ah, I see... I had the guy that finished my last shop floor do that and it was awesome. For a while anyway...until the guy that did my spray in foam insulation got foam all over it. It was smooth enough you could clean it up mostly with a dust mop.

I don't think this floor is smooth enough to do the same. It's not bad but still has a bit of grit to it. Won't be able to tell for sure until all of the construction dust and debris is pressure washed off it.

I'm seriously considering doing Option #2 above though. I bet the finish ends up close to what Charlie has if not a little smoother, I"m just not sure about the sealer put on after. My experience with just concrete sealer has not been good. Once it starts to fail and come up, it can be worse than just plain dirty stained concrete floors.

I have now learned more about shop floor coatings than I ever wanted to know.

Thing is, I think I've figured out the best solution for me. If you want one of the hard epoxy like coatings to "adhere" to your concrete properly...you need to open up the pores of the concrete which means grinding...which means money. Once you have it open your choices depend on how smooth you want it to be once done. To get super slick and glossy, you need to grind it smoother (like wetsanding paint).

If not that worried about smooth looking, you can just clear it and be done. The acrylic clear quoted to me in the $2.50 per foot option above is not really recommended for auto shop uses though, it doesn't play nice with liquids that stain. We have decided to go with a Polyaspartic clear on top of the 80 grit ground concrete which will give the floor an epoxy like protection but in clear so it can be touched up if needed. Should be smooth enough to sweep up with a dust mop as well.
