Didn't do my own but we have a concrete bar top on our back patio. They had rebar too close to the edges and it rusted, we had it epoxy coated with a slight texture and it looks great, it was coated probably 6 years ago, still looks brand new when I clean it off.

I did my own. I built a base out of cinder block with brick outside.
If you plan on doing it yourself the main thing I’d suggest is vibrate it way more than you think you need. That’s where I messed up on mine.
Also used a piece of cardboard to get your pattern. You will want to use the downside of the mold.
Your mold needs to be melamine

Me and my Brother built this one. Poured in place, let cure.
Sanded with several different grit sizes, acid stained, then 3 coats of epoxy. It was our first attempt, the biggest problem we had, being outdoors, was keeping bugs out of the epoxy before it could set up.
16 ft. long by 2 ft. wide

When you build your melamine form, use black silicone in the joints along form so you get rounded corners on your countertop. Vibration as mentioned above is key. Longer slabs you can use some chicken wire mesh to hold it together.

I've done a few for others, QuikCrete has a dedicated mix for coutertops or you'll want to use a liqui-crete type additive, if not both. The additive gives it a more fluid consistency and really helps cured strength and minimizes air bubbles. If you want a decorative edge, trim out the bottom of the mold with small crown, quarter-round, or other decorative pieces of trim. Nothing too fancy unless you have access to release agents like what is used for denture processing. If you've never done this before then practice making a few paver-sized test runs, aything over a few feet in size you'll want a good and very level support surface setup too.
