RAL 7031 - Blue Grey

What Is RAL 7031 Blue Grey Color Gel Coat?

RAL 7031 Blue Grey Color Gel Coat is a made-to-order polyester gel coat matched to RAL 7031, Blue Grey. In polyester and vinyl ester composite construction, gel coat is the first layer applied to the mold and becomes the smooth, colored outer skin of every part pulled from it. The Blue Grey color runs through the gel coat material itself rather than sitting on top as a secondary finish.

Why Choose RAL 7031 Blue Grey Color Gel Coat?

Blue Grey carries a subtle blue cast that gives it a calm, cool quality distinct from the neutral greys. That blue undertone adds a measured coolness to finished parts, making it a popular choice for interior and exterior composite panels where a grey needs to feel slightly cooler and more refined. Fibre Glast matches it precisely to the RAL 7031 standard, so the color is consistent and repeatable across production runs. For physical color confirmation before ordering, the #4008-A RAL Color Book has printed swatches of all 188 RAL colors.

What Are the Best Applications for RAL 7031 Blue Grey Color Gel Coat?

Interior and exterior composite panels, equipment housings, and architectural parts where a subtle blue-grey tone adds a cool, refined quality to the finish. It can also be used for open-air repairs when combined with Duratec Hi-Gloss Additive.

How Should RAL 7031 Blue Grey Color Gel Coat Be Used for Best Results?

Apply RAL 7031 Blue Grey Color Gel Coat by spraying onto a properly prepared mold surface, catalyzed with #69 MEKP at 1.5% to 2.5%. Build up 4 to 5 coats at about 5 mils per coat, allowing 15 to 20 minutes between each, for a finished thickness of 20 to 25 mils total. The #122-A Gel Coat Thickness Gauge takes the guesswork out of film build. Use #70 Styrene Thinner or Duratec #1039/#1040 to reach spray viscosity if needed. One gallon yields 40 to 80 square feet of coverage. As a made-to-order product, all Color Gel Coat sales are final.
