Just place your object with the glow in the paint under direct sunlight for 3-4 hours to be fully charged.

For the paint to charged fully, the light should be direct and be of consistent strength. Shadows and inconsistency of light, especially during sunset, will affect the paint’s charging, thus affecting the glow.

Most of the glow we see is a reflection of light, meaning light colors reflect light, while dark or dull colors absorb light.

Since glow in the paint does emit light, it means that when painted on a lighter background, the light will bounce off the white surface towards the viewer.

The opposite is also exact; when painted on dark surfaces, some light will be absorbed back and will not reflect towards the viewer.

Glow in the dark paint, painted on a lighter background and charged for at least 30 minutes, will glow for long and bright.

3.    Drying Between Coats

The application of the paint should not be continuous. Layer after layer is the trick.

Please give each layer of paint at least 15-30 minutes to dry before applying another layer.

For better results, let the painted coat dry first.  When you paint over paint, which has not dried, the glow of the coat will vanish.

For quicker results, a hair drier can come in handy.

​​At a minimum, at least three coats can do a good job.

If you want more brightness, the application of more layers will do you justice.  The more the coats, the better.

The use of many thin coats will give you a better and longer glowing effect.
