Does Fluorescent Spray Paint Glow In The Dark?

Glow-in-the-dark spray paint is super cool and lets you do some very fun things with decorations and design. Plus, it can help add some extra safety points to various projects. With all of the options out there, you might be wondering, does fluorescent spray paint glow in the dark, or do you need something else?

Fluorescent spray paint does NOT glow in the dark by itself. Rather, fluorescent spray paint will react to UV light, commonly known as black light, to produce an intense glow that resembles glow-in-the-dark paint. Phosphorescent spray paint, on the other hand, will glow by itself at night once activated by natural or certain artificial lights.

Let’s learn more about how fluorescent spray paint works and how best to use it for your next project!

Does fluorescent spray paint glow in the dark?

Fluorescent spray paint doesn’t glow in the dark. However, it does glow very brightly under so-called fluorescent black lights. Fluorescent spray paint reacts to black light which is nothing but long-wave ultraviolet (UV) radiation, which is commonly known as black light.

Through the mechanism of fluorescent pigments, UV-sensitive paints absorb the invisible ultraviolet light and emit visible light. Under normal daylight or other visible lights, fluorescent spray paint appears a bright neon color. However, when exposed to black light, it glows brightly.

It can be used for costumes and stage shows, and it allows you to create black light effects like invisible images, dual images, and 3-D effects. It’s used extensively in rides at amusement parks.

When exposed to long-wave UV radiation, fluorescent spray paints glow. Black-light effects are created using ultraviolet (UV) wavelengths that are emitted by certain types of lighting, including sunlight and some artificial lights.

Fluorescent spray paint comes in a wide range of bright colors and is used in theater lighting and effects, posters, and as entertainment for children, among other things.

What exactly reacts with the black light in fluorescent spray paint?

Fluorescent spray paints contain chemical compounds that absorb ultraviolet (UV) radiation from sunlight and emit it as visible light at a different wavelength. Humans perceive this light as the strange glow of fluorescence.

The painted surface also absorbs any ordinary visible light striking its surface, which tends to wash away the dim fluorescent glow. So viewing fluorescent paint needs a long wave ultraviolet light which emits little visible light. This is called a black light.

It has a dark-blue filter material on the bulb, which allows the invisible ultraviolet (UV) radiation to pass but blocks the visible violet light produced by the bulb. Fluorescent paints are most effective when viewed in a darkened room but can be used in any lighting conditions.

Types of fluorescent spray paints

There are basically two types of fluorescent spray paints, ‘visible’ and ‘invisible’.

The visible fluorescent spray paint contains ordinary visible light pigments; therefore, it appears a particular color under normal lighting conditions. However, under black light, it appears brilliantly.

Invisible fluorescent spray paints appear translucent or white under normal daylight, but will glow brightly when exposed to ultraviolet (UV) light. Because these paints are invisible under ordinary visible lights, they can be used for creating a variety of clever effects using them.

Both types of fluorescent paints benefit from using them in environments where there is a contrast be­tween clean, matte black backgrounds/borders and darker colors.

Both types of paints are used for artistic lighting effects in black box entertainment environments such as theaters, pubs, shrines, etc., particularly when using LED lighting.

You can use fluorescent spray paint to create a glowing border around an image or even add a glow to an object like a picture frame.

Start by spraying a very thin coat of fluorescent spray paint onto the desired area. Wait about 10 minutes for the paint to dry, then repeat the process until you achieve the desired thickness.

If you want to achieve a brighter glow than usual, apply several coats of fluorescent spray paint instead of just one. In this way, you’ll get more coverage and a stronger glow.

When applying the final layer of fluorescent spray paint, wait until the previous layer is completely dry before adding another coat. If you don’t do this, the new layer may not adhere properly to the old one.

Once all layers of fluorescent spray paint have dried, place your artwork into a black box or other environments where UV light can shine through the paint.

This is how easily you can create some amazing effects with fluorescent spray paint!

Fluorescent spray paint is available at many craft stores. It’s easy to find out if your local store carries it because the label should say “fluorescent.” These spray paints are also available online. So, pick any color that suits your project and start making the art!

Summary of fluorescent spray paint

You should also consider whether you want to change your costume permanently or just have fun experimenting. 

Always check the instructions before spraying. Fluorescent spray paint does not glow in the dark but glows heavily in the black ultra-violet light, also known as the black light. If you have any further queries regarding fluorescent spray paint, please let us know.


What is the difference between neon and fluorescent spray paint?

Neon can describe many shades of a particular color, including fluorescent but not necessarily luminous colors. They’re also used in many theatrical productions, especially those with special effects. Both of these labels indicate that the paint doesn’t necessarily have night reflective properties.

How long does fluorescent spray paint last?

If the fluorescent spray paint can is not opened and kept in dry and cool conditions, it can last up to 3 to 5 years. However, the fluorescent spray paint will glow as long as a black light is shone on it.

What does fluorescent spray paint do?

It’s a type of spray paint that fluoresces when exposed to UV light. This means that it glows brightly when exposed to black light. You can use this to create interesting effects.
