Sorry for the delay in responding. Evidently I missed the notification of a reply.
I used concrete dye from menards. I think it was one pint per bag of concrete. I think it took me 3 bags/pints, but it might have been 4. I bought some diamond polishing pads from amazon and a variable speed polisher from harbor freight. It's not supposed to be used with water, but wet polishers are pretty expensive, so I didn't want to spring for one of them. I built a form with a piece of melamine covered mdf and square trim pieces. They've got some flex to them so I could bend them to get the curve I wanted for the front. They were the thickness I wanted the counter to be, so I didn't need to cut them down, which was nice. I had no idea what I was doing, so I just did what "seemed" right and it worked out pretty well.
After a week of setting I took it out of the form and ground it down to expose the aggregate. The polishers need to be used wet, so I'd spray down the concrete, polish, spray, polish... Exposing the aggregate also exposes lots of holes. I saved a little bit of dye from the concrete and made a slurry to fill the holes that will be exposed when you polish. The color doesn't have to be exactly the same because it's already all over with the exposed aggregate. After that set I'd polish it again, and then filled again. I think I filled 3 times to get all the holes.
There is a lot of writing online about concrete counter tops, and I read a lot of that before I did mine. Hope that helps. let me know if you have any more questions, or want clarification on a specific spot.
