Hi, I wonder if anyone has tips on how to color concrete black. Or at least dark.
I tried with carbon black pigment and expanding concrete. Pigment about 5% of the mix. There was hardly any difference from the original color.
How can I get the darkest possible slab? It will be a countertop.

We colored plaster with Kimrök, it went well. However, I don't know how much is needed to color concrete. http://www.nackabyggnadsvard.se/p/farg-tapeter/ovrigt-maleri-farg/kimrok-1-kg.html
