Dyeing Mortar

Different ways to add color to concrete


What's the best method of dyeing mortar?

— Les, Reno, Nevada


Tom Silva replies: There are a couple of different ways you can dye mortar. You
can mix the mortar and then splash the dye on it once it's in place, but
with this method the dye won't get very deep into the material. Or you
can dye mortar at the time you're mixing it, which allows the color to
mix completely throughout the material. If you're looking for a choice
of colors, I'd recommend going to a cement or concrete yard and they
ought to be able to give you more guidance. But I would think you should
be able to find plenty of options for mixing, because I know offhand
they use grays and blacks and reds and greens when using concrete stamps
— so there are lots of different colors.
