Luminous glow-in-the-dark paint can be a lot of fun. It can make eerie Halloween decorations or be used to decorate a teen's bedroom. Luminous paint can also be used to mark paths or for warning signs. Luminous paint looks and rolls on the same as normal paint, but after absorbing light during the day, this paint glows at night. While luminous paint can be purchased both online and at hobby shops and home centers, you can also make it at home. The main ingredient in luminous paint -- besides the paint itself -- is powdered zinc sulfide, available online or through some large paint stores or hobby shops.
Items you will need
- Latex paint
- Measuring cups
- Zinc sulfide
- Stir stick
- Brush or roller
- Airtight container
Mix 1 ounce of luminous zinc sulfide powder per every 10 ounces of latex paint. Any color of latex paint can be used, but a flat white base latex paint glows more brightly than colors.
Paint a small test area with the luminous paint you've made. Allow the paint to dry as per the paint manufacturer's instructions. Fans may help the paint to dry faster.
Expose the painted test area to bright light and then observe the results when the area is placed in complete darkness. If you want a brighter glow, mix additional zinc sulfide powder into the paint in increments of 1 ounce of powder per 10 ounces of paint until a sufficiently bright glow has been achieved. Keep in mind that adding additional zinc sulfide to the paint may cause the paint to glow more green than white. To achieve a whiter glow, dilute the mixture with additional latex paint until you achieve the desired level.
Store unused luminous paint in an airtight container. Surfaces painted with luminous paint should retain their luminosity for an indefinite period of time.
Tips & Warnings
- Do not mix zinc sulfide with acids as this could produce a toxic gas.
