Calculate how much pigment you will need to add to the concrete. This is typically no more than 7 per cent of the cement content of the concrete. Cement content can be between 10 to 15 per cent, depending on the concrete mix.
Set up the cement mixer in the yard, where you can mix the concrete without worrying about making a mess on a floor.
Turn on the mixer and add about half the bag of concrete mix at a time. Add water to the concrete mix with the garden hose. Refer to the instructions on the bag of concrete mix for the correct amount of water. The consistency of the mix should resemble peanut butter.
Repeat step 3 until you have added all of the bags that you will need to complete the countertop.
Add the amount of pigment to the mix that you calculated in step 1. Continue to mix the concrete in the mixer for about a minute. This allows the pigment to thoroughly colour the concrete.
Fill a bucket with small amounts of the concrete and then begin pouring the concrete countertop.
Tips and warnings
- The cement content of the concrete should be indicated on the bag of concrete mix.
- Rent the cement mixer from your local Home Depot or home improvement store.
- Do not put entire bags of concrete into the mixer at once, or it will mix unevenly.
