Colorkast Black Pigment is the professional standard for achieving deep, soulful blacks in surfboard glassing. This high-quality "paste-style" colorant is engineered to provide a rich, jet-black finish that remains lightfast and UV-stable. Unlike inferior liquid dyes that can sometimes shift toward a muddy purple or brown over time, Colorkast’s premium formula ensures your lamination stays true and saturated for the life of the board.

This colorant is incredibly versatile in the glassing bay: depending on the "color-load" added to your resin, you can achieve a sophisticated transparent tint or a high-density opaque pigment. As a Resin Tint, it creates a "smoke" or "charcoal" effect, allowing the wood stringer and foam texture to show through with a dark, translucent depth. When the color-load is increased, it becomes a solid Opaque Pigment, providing the ultimate "hide" for foam imperfections and creating iconic, high-contrast rail bands or full-board "black-outs."

Colorkast paste-style colorants are highly concentrated and disperse quickly in both polyester and epoxy resins, ensuring a streak-free, uniform finish that won't compromise the integrity of your resin cure.

Key Features:

Paste-Style Formula: Maximum pigment concentration for a true, deep black with superior resistance to UV fading.

Jet Black Palette: Delivers a clean, neutral black that stays bold even in high-UV marine environments.

Variable Transparency: Effortlessly transition from a light "smoke" tint to a deep, solid opaque black.

Professional Consistency: Formulated specifically for the surfboard industry to ensure a high-gloss finish and perfect cure.

Resin Compatible: Works seamlessly with all standard laminating and surfacing resins.

Pro Tip: Black is the most unforgiving color in glassing. To achieve a perfectly flat opaque finish, ensure your resin is mixed thoroughly and your lamination is pulled tight to the foam. Any "resin pools" or thick spots will be visible as variations in the surface—a tight, even pull is the secret to a professional black-out.
