First off, I estimate this countertop at around 160lbs...fun getting that thing out of the subterranean shop! The form was made from a sheet of melamine with pine added for the chamfered corners and black silicone to seal the square corners. The whole form got a coating of paste wax to help pull the counter off once it cures. 1" thick rigid foam is used to create a cavity to help take off weight (the counter edges are 2" thick). To smooth it, I started by dry sanding and finished with wet sanding where I simply wet the slab with water and used a high grit sanding disk. To seal the counter, regular 2 part epoxy resin was used. The first coat was spread and then scraped smooth when it soaked in, the 2nd coat was just a thin layer. The boards on the back were stuck on with epoxy since a hairline crack formed when I flipped the counter over because I took it out of the form too early. I didn't use reinforcing steel because the concrete mix I used is fiber reinforced, which is sufficient for this application.
