I need to do some maintenance on my Big Green Egg cabinet. It has 2 formed concrete tops and the shelf the Egg sits on that were stained brown and used to have a glossy protective finish. About 13 years ago. 🙁

Anyone have any suggestions how I handle refinishing these and making them look 1/2 decent again?

You can just reseal it to gain the gloss back but I don’t think you will get rid of the scratches without grinding the stain and sealer off and starting over again with restain/reseal process. No experience with it but Just another thought if its sticking well is one of the expoxy kits. I think the stain looks better though personally just more work involved.

It’s a grill table so it doesn’t need to be beautiful. Grinding the finish all off sounds like no fun.
 
I did my own concrete counterstops. Used a Harbor Freight 7" grinder/polisher with a 5" diamond cup-style wheel (so it contacted the surface flatly).

It wasn't bad (with ear & eye pro and a dustmask). I bought some etching stain off the internet & followed the directions... came out great!

The acid stain I used reacted with the concrete to form the stated color; it didn't look anything like the advertised color to start with. I don't think you'd have to get all the stain off if you're going to go with similar earthtones/browns. But you would have to get the sealer completely off. That said, if the scratches aren't smoothed out, they'll stand out when stained, just like scratches in a wood top.

Epoxy paint would be easier, but would be monchrome (most likely) and less natural/interesting looking.

Well now that I got a fresh coat of stain on the wood the concrete top looks even crappier.

Wipe it down with an acid stain close to the same color , allow it to dry and wipe it down again. Allow it to sit a couple of days then seal it with food grade concrete sealer

This is what I would try.
