This rubber edge from will give you a finished edge on your countertop that looks like stone. The manufacturer has many different textures to choose from. The form is 2 inches high and 8 feet long. You can cut it to length.
This is one of the drills we use to screw the forms together.
We also use the impact driver but this one will do everything you need. Make sure you pre-drill the holes before you screw, this eliminates cracking the forms.
Put a little Vaseline over the screw head to keep any spilled concrete from sticking to it.
These are the sink knockouts you use to make holes in your countertop for the faucet and hot & cold water handles.
We use black caulking and a smoothing tool to caulk the corners and edges of the forms after they are screwed together.
This provides a nice smooth edge when you strip the forms.
Get the caulk bead finishing tool on Amazon also.
FORMS - We use melamine 4x8 sheets for forms and cut them to size. Melamine has a very smooth surface which makes polishing that surface much easier. You can get this at your local lumber company. You could also use smooth finished plywood although you may see some of the wood grain in the surface of the concrete after you strip the form.
This is the kind of mixer we use. You can use a 1/2 inch drill or just mix the concrete in a wheelbarrow.
This mixer is just a lot faster and makes mixing the concrete very easy.
This is the mixing tub we use. You can easily mix an 80lb bag of Quikrete in this tub with the drill mixer.
When you're done, just rinse it out and use it over and over again.
This bag is a "just add water" concrete mix for making concrete countertops.
The amount of bags you'll need depends on how thick your countertop is and how many square feet it is.
This bag from Cheng concrete countertop mix contains a color pigment, superplasticizer, and fibers.
You just add it to a 80lb bag of Quikrete 5000 or Sakrete HIgh Strength Concrete Mix.
You can make your own countertop mix from scratch. Here's my list of ingredients you will need.
This polishing kit includes the polisher and all the polishing discs you need.

This is what you use to fill any voids and pin-holes after you polish up to a 400 grit.
Just mix the slurry and rub it into the voids using rubber gloves. Choose the color that best matches your concrete.
Scrape off the excess with a plastic putty knife, then let it dry overnight and continue polishing.
For some more information and a video about polishing, check out my page about finishing concrete countertops.
This is a food-safe topical acrylic sealer, not a penetrating sealer. If your concrete is NOT highly polished and somewhat porous, this is a good sealer for you.
This will cover 45 - 60 sq. ft. per bottle and you will apply at least 3 coats. You can also order the gallon container if you want.
This is a food-safe penetrating concrete sealer for countertops.
It penetrates deep into the concrete and doesn't leave a film on the surface.
It's better for more polished surfaces.
This kit includes a food-grade daily cleaner, protective wax, buffing pad, and a micro-fiber towel to clean and maintain your concrete countertop.
Here's a video showing you how to apply the sealer.
