Hello,
I am trying without success to get a deep "true" black countertop color. I used Black pigment from Alabama pigments and it looked very black in the mix but dried to a dark gray. I tried using an Eco Procote soy based stain over it and it wouldn't bite in without leaving swirl marks. Oh, it's a GFRC top by the way, I don't know if that matters or not. Then I just used an acid stain from concrete solutions, definitely more black, but with way too much brown undertone. So how on earth do I get a real true deep black?
Thanks,
Will

I've been getting good results using a black liquid pigment instead of powder. Much more solid and darker colour.
Try Smith Color Floors black concrete dye.
I use a Brickform Ebony Acid stain and do not neutralize for 24 hours. When I use Sparta Cote 2 part epoxy sealer it really gives you the solid black color.

The solution could be at hand if this is still an issue

what is the solution Murray? I have some black tops coming up and hate what it does to my mix. How do I cure the problem ?

Use white cement instead of gray.

BlueConcrete has the solution.
