Shiny concrete finish

Getting ready to do shop floor. It now has a rough brush finish that I would like to make smooth and shine. What would I need to finish floor. Smooth out brush finish and Kind of paint, epoxy o use. This will be primarily a wood shop for me to tinker in.

I'd think you'd have to sand the concrete to make the floor smooth. Paint might lessen the texture some. Is there a vapor barrier under the slab?

I've seen commercial shops with really thick, relatively clear, epoxy coatings on their floor. Not sure where or if that is available for DIY application.

Any DIY coating will be thin application so your not going to get rid of the current finish.

I had my garage epoxy coated, they ground it down to virgin finish but it was smooth finish to begin with!

You would want to grind and polish the floor to get rid of any texture. If you want to DIY you would need to locate a rental store with the proper equipment. There are youtube videos on grinding and polishing too. You would want to degrease oily areas or you will have adhesion issues with your coating. After you pressure wash it, you will need to allow plenty of time for it to dry since moisture trapped in the concrete will affect adhesion as well.

Years ago we designed a building where the client wanted an exposed aggregate floor in the corridors between shops. When it was completed, the client decided it wasn't such a good idea after all and asked what could be done. After a bit of research, we had them hire a terrazzo contractor to grind down the floors. It worked pretty well, but was expensive because the aggregate in concrete is so much harder than that in terrazzo.
