The first question on this countertop is whether it is GFRC (glass fiber reinforced concrete) or not. Many concrete counter companies use it. When we were fabricating counters, we did. If you get too aggressive with a GFRC counter, you might go through the cream and expose the fiberglass. That would not be desirable. It looks from the pictures, that you have damage from impact, acid, and abrasion. I'm not sure that all stone restoration companies would tackle this, or should. The impact areas will have to be filled with color matched slurry. The acid etched areas and damaged film will need to be carefully ground off but you have to determine the sealer that was used. Some would not be compatible with a food grade safe epoxy but if not, you would then need to grind all of it off of every damaged slab and recoated. Make sure that you manage customer expectations and allow for the cost. I would do time and materials with a not to exceed.Joyce Harris

Subject: Re: Poured ConcreteYes. I've resurfaced several concrete countertops before. I can guide you if you need help.
Like Fred mentioned I would reach out to a stone restoration company and someone with experience dealing with concrete.
Few warnings! I would not drop down too low on grits because you could potentially expose aggregates and or open up too many pin holes which will create another issue or add more work. Been there done that!
I usually start with a 400 resin pad and 70% of the times it will remove most etch marks and make the surface look really good. On some occasions I will drop lower to a 100 or 200 resin but before I do, I have the client sign off that it may expose more aggregates during the process.
You could densify the concrete after that 1st honing step and continue polishing up to desired polish outcome.
Lastly I would either coat it with a food grade safe epoxy or seal it with a concrete sealer and burnish. The results will look spanktacular lol!
If you need guidance just send an email or call and I can explain it better. Good luck!
As a final note this should be charged as a premium.

Good morning! Does anyone have experience with poured concrete? I have a homeowner with a rental property and the tenant destroyed the countertops. Trying to decide if it's easier to fix or replace?
Thank you!Beth
