General Overview

Ultra Green Glow Paint is a durable, long lasting, solvent-based acrylic phosphorescent paint that glows brighter and longer than any other phosphorescent paint on the market.

Brightness and Duration

Ultra Green Glow Paint is the brightest glow paint sold anywhere.  In its first seconds after charging, it is brighter than the popular Cyalume Glow Sticks.  Ultra Green is 10 times brighter than the popular Zinc-based glow in the dark products available in most department stores.  Technically, it will continue to glow for days.  But us humans can see it for about 12 hours after a full charge.  Each gallon contains two pounds of the brightest glow in the dark pigment available.

Ultra Green Glow Paint actually glows a green-yellow color, also known as lime.

Daytime Color, Opacity, Transparency, and Translucence

The Ultra line of products are translucent when in a lit room and glow brightly after a charge in a dark room.  This means they are almost unnoticeable during the day when painted thinly and consistently.  Since the paint does have a slight white tint, it is even more unnoticeable on light or white surfaces.  Thicker applications or those on a dark background will still be translucent, but more noticeable.  There is no such product as a "daytime transparent" glow paint as you may have seen advertised.  But the Ultra and our other lines marked "almost clear" are relatively close to transparent when used properly.  For a more opaque color in a lit room, consider our "Daytime" series.

Chemical Makeup

The raw glow pigment is: Alkaline Rare Earth Metal Silicate-Aluminate Oxide Europium Doped

Paint Properties

Glow Inc.'s brand of glow in the dark paint is a custom formula designed to maximize brightness in a durable all-purpose paint.  The engineers included a suspension system that supports the relative dense glow in the dark particles.  It contains no fillers or impurities such as ultraviolet filters, which interfere with glow pigment.  As a solvent-based acrylic, it is extremely durable for indoor and outdoor use and has strong adhesion to almost all surfaces.  Drying time is between 10-15 minutes, but should be allowed to cure overnight.

Our paints are created by mixing the raw pigment (glow powder) with the custom designed paint in a ratio of 2 lbs of glow in the dark pigment to 1 gallon of paint.  This high ratio along with the high clarity medium results in the brightest glow in the dark paint sold on the planet.


Solvent-based paints are considered a Flammable Material by the US Department of Transportation.  Therefore, there are strict guidelines for shipping that depend on quantity.

1.  Special packaging is required and will be added to your shipping total.

2.  We can not ship paint internationally without costly hazmat packaging and procedures.

3.  Quantities up to 1 fluid ounce can be be shipped via air or ground.

4.  Quantities between 1 fluid ounce and 1 quart must be sent via ground.

5.  Quantities above 1 quart must be sent via freight.

6.  Purchases of a gallon are sent as 4 separate quart packages.
