Glumionous glow in the dark & photochromic powders can be used in many applications and mixed into many different mediums. The possibility are only limited by your imagination.

General Tips & Instructions

Selecting a base medium

  • The best results come when the base medium is preferably a clear or semi-transparent.
  • The base medium should be have a PH between 7-9 so as not to deactivate the chemical effects of the pigments.

Mixing Tips

  • Higher ratios of powder to medium will provider brighter results, but going higher than 30-40% will not yield better results.
  • When mixing, add the medium to powder, not powder to medium. That way, you can stop when desired the concentration or effect is reached.
  • Never grind (ex: using a mortar & pistil) the pigment powders before or after mixing. This will destroy the crystal structure and decrease luminosity.

Application Tips

  • When painting, apply paints on top of a white or light colored background or primer. Darker backgrounds will absorb light and diminish their brightness.
  • A thicker coat will increase the brightness. It may take multiple applications of your medium to achieve this.

Powder Painting Technique

Instead of mixing into a medium, our glow-in-the-dark powders can be applied to the surface of the object you want to glow and sealed in, ensuring a bright, even glow. The only items required for this technique is a pack of glow in the dark powder and a can of clear spray paint.

Note: this method could be a little difficult for painting large objects.

Method of Painting

  1. Pick up the object you wish to paint. Mask off the areas you do not wish to paint.
  2. Spray a very thin layer of clear coat over it
  3. While the surface is still sticky, sprinkle glow powder over it. Make sure the glow powder covers the entire area evenly.
  4. Shake off the access powder and spray another thin layer of clear coat over the object to seal the first layer of glow powder.
  5. After each coat, check the coverage of the painting by exposing the surface to UV light (or sunlight) and looking for a consistent glow.
  6. For an even and bright glowing surface, we suggest building up the coats of glow layers by repeating Steps 2 through 4 a few times. Keep repeating the process until you are satisfied of the coverage and brightness of the glowing surface.
  7. Finish your project by applying at least 2 coats of clear paint over the glow surface. This is to protect your work from chipping or flaking off. If you expect the painted surface to withstand more robust contact, you may want to use an clear epoxy coating.


  1. Powder painting can be completed a lot faster because you don’t have to wait for each layer to dry
  2. You can ensure a concentrated, bright glowing surface because you are using the powder directly.
  3. You don’t have to clean up brushes or deal with mixing ratios


Glow-in-the-dark Powders

  • Most Gluminous glow pigments should only be mixed into oil/solvent base mediums. Water-based mediums will deactivate the product. Consult the individual colors for water solubility.
  • If possible, we suggest using plastic, ceramic, or glass mixing containers and utensils. Certain metals can react with the material and produce undesirable results.

Mixing Ratios

  • The ratio of glow powder to your medium ranges from 5% to 40% by weight depending on the application and medium


Photochromic Powders

Mixing Ratios

  • Resin: 1-3% for Epoxy Resins, 10-30% for UV Resins
  • Paint: 10-30%
  • Ink: 20-40%
