Specialty & Custom Colors

Specmix Color Palette

Specmix offers a full range of colors that are available as premeasured canisters. Add one package of color to one bag of mortar to achieve the desired color. For larger orders (35 bag minimum) the color can be integrally mixed at the factory so you just need to add water.


Specmix Canisters are available in 25 colors. For more information on our mortar color options Contact Us.


Henry Frerk Sons Custom Colors

If you need a custom color outside of the Specmix color options, we offer our own range of custom colors from our sample library, and if we don’t have it we can match it.

We offer two options:

  • Fast track match: submit a sample and we will review our existing colors to see if we have a match. If we do you can order color packs (one color pack to one bag of mortar) up to 20 bags. For larger orders (35 bag minimum) Specmix will factory mix the colored mortar. Just add water.
  • If we do not have an available color we will custom match the mortar. This is a fee-based service.


Note: Henry Frerk Sons custom colors are available for Mortar Types N and O.
