How to protect floor

[hydrojim]

Just had a 30' x 40' slab poured in preparation for a 30' x 40' steel building.

The building with be having a lift installed and will be mainly used for car repair/maintenance. I expect to be grinding, welding, and inevitably spilling all sorts of fluids on the ground.

What should I do to protect the floor? I was thinking about some kind of epoxy coating but not sure where to start with this.

All suggestions would be appreciated.

I'll be listening, I'm doing the same thing. I like the look of a coated floor, just not sure how it will hold up to sparks, dragging floor jack, etc

The world is your oyster. Epoxy is great for auto-service but be careful when you weld right on the ground.

I'm a fan of epoxy flooring for auto motive areas..congrats on the new shop!

Ensure quality surface preparations! did I mention surface preparations?

Does this plan sound good?

Grind surface with 200 grit diamond
apply densifier
grind surface with 400 grit diamond
grind surface with 800 grit diamond

I think that will give me a hard and smooth surface to hopefully avoid staining. I think my work is too abrasive/corrosive for any sort of epoxy. Welding, brake fluid, oil, and fuel are not known to play well with others.

My only questions is how do I prepare the floor for the densifier. The grinding stage will leave lots of dusts and I can't imagine that brooming the floor will take care of things. Any suggestions for this step?

If doing what appears to be a polished floor you generally you need to start with 40 then go 80 then 120 before you go right to 200. We do a lot of polishing, and can never start at 200. Apply densifier after 400.

Apply stain blocker after the last step and then burnish in. We carry these products if needed.

There are several ways you can go. A good coating, and protect from weld slag; densify and a good sealer such as ghostshield 8505 and the list goes on and on. If it was me, I would forget the welding blanket and the be ticked off that I ruined my floor.... So I would probably go TL37 followed by two coats of 8505

You can jump to a higher grit diamond if you are starting with a smooth power-troweled floor, otherwise you will have to go back to at least 50.

Densify at 400 (any basic densifier is fine) (sweep/blow dust prior to spraying on with pump-sprayer)- dust gets less as you move up.
Apply stain-guard like this when last pass has been made, burnish after application per the instructions...
