How Can You Increase The Time For Your Paint to Glow?
There are a few things that you can adjust to increase the time your dark paint will glow. Let’s see what those: are-
- Quality of paint – As in all things, here also the quality matters the most. You can’t expect color for longer durations if you have bought a cheap one. After all, quality had a price! These won’t even glow after recharging.
- Location – Outdoor paints shine more than indoor ones. So, if you apply your paint outside, it will glow longer than expected.
- Background – Lighter background means more glow, and it is so because light reflects light which appears as a glow.
- Thin coatings- If you apply extremely thick coats of paint, you won’t be able to enjoy the glow at all.
- Surface – Smooth surfaces reflect light while rough ones absorb it. So, try to apply the paint on a smooth surface for the most glow.
