I Need Help Matching My Stucco’s Color for Fog Coat

Henry’s stucco exterior was fog-coated years ago with a specific color from Expo Stucco, but since the company seems to be out of business, he’s wondering if it’s possible to color match fog coat the way one can match paint. He’d like to know how to go about it so he can avoid redoing the entire house when touch-ups are needed.

Question from Henry:
My stucco exterior was fog-coated years ago with Expo Stucco's Base 4/Color 122 ("Tempest"). It seems like Expo is no longer in business. Is there a way to color match fog coat just like one can do with paint?

If so, how do I get that done? When my house exterior needs touch-up, I'd really rather not have to redo the whole house. Thanks.

Answer: Hi Henry! Yes, it is possible to color match fog coat, but it will require a custom color match from another stucco manufacturer. For the most accurate match, you’ll need to provide a physical sample of your existing stucco.

If you don’t have a loose piece available, you might need to carefully remove a small section from an inconspicuous area of your home to bring to a stucco supplier or manufacturer for analysis.

This approach is the best way to ensure the new fog coat color is as close as possible to the original. That being said, blending touch-up areas with fog coat can be tricky.

While you can spot-apply fog coat to specific areas, it often doesn’t blend as seamlessly as expected. This is usually because of natural variations in color with cement based finishes and over time the color fades and can be inconsistent.

Fog coating is typically applied to entire walls from corner to corner, in order to achieve a uniform color and appearance. If you decide to spot apply the fog coat, test a small, inconspicuous area first to see how well it blends before moving forward.
