Glow In The Dark Paint for Walls: Does It Last Forever?

how long does glow in the dark paint last

For those who want their walls to have a unique appearance, glow-in-the-dark paint is one way to express your creativity.

As a matter of fact, the glow of glow in the dark paints does not last forever if you have applied them on your walls indoors or outdoors. This means you cannot expect to keep the objects shining forever if you apply the paint once.

When chosen wisely and applied properly you should expect the permanent paint itself to last about a decade before it needs a new coat.

With that said, while the real glow does not last forever, the paint can be recharged and can be made to glow again using various ways.

Although this type of paint has become popular in recent years, it has been around for quite some time.

Understanding what it is, how it works, and where it can be used can provide you with many creative ideas.

Here in this article, I will help you walk through all the things you need to know about these fun paints along with a few questions you may have in mind about them.

What is Glow in the Dark Paint?

This is a kind of luminous paint for walls that are infused with phosphors that trap sunlight and glow for hours afterward in the dark.

Phosphors have been used in paints for quite some time, most notably by the military before they made their way to the civilian world.

How does it work?

The phosphors that infuse the paint are activated or charged by ultraviolet or UV light that mostly comes from sunlight.

Unlike most artificial light that contains little to no UV, sunlight is generally the preferred method of charging the phosphors.

This means that you set the object which is covered in glow in the dark paint outside for three to four hours.

Once charged, it should glow for the same amount of time. This also means that walls that are outside your home can be charged by the sun before they glow at night.

How to use it on walls?

Maybe you want to put them on the walls of your kids’ room. Yes, it’s an exciting idea!

No matter whether you want to paint the fresh walls of your room or want to renovate the old walls, there are options available.

In most cases, glow-in-the-dark paint that is applied to walls is generally done in the form of a painting or mural.

For painting, specially developed paints are available in the market that you can try. Make sure that you apply them right – if you want to glow them bright.

If required take the help of an experienced painter to know which one is the best option for you.

While you can paint a wall a solid color, it is far more creative and interesting to create a mural instead which combines different colors of glow-in-the-dark paint.

This can be a good option for those who want to save themselves from the hassles of repainting and the high costs involved.

How to remove it from walls?

When the paint no longer sustains its glow or is no longer needed, it can be removed just like any other paint.

While wall murals are pretty easy to remove; if it’s the paint, you will need to loosen and scrape the paint away before applying another type of paint to the wall itself.


The Lifespan of Glow in the Dark Paints

Glow paint for walls is infused with phosphors that are energized by ultraviolet or UV light.

Since UV light is part of sunlight and even the artificial lights from light bulbs, it provides the energy that charges the phosphor which results in a glow that lasts for hours between charges.

However, phosphors will eventually lose their ability to hold a charge so wear out with time. This means that you will need to add a new coat of luminescent paints every so often.

How long the charge lasts will depend on how many times the phosphors have been exposed to UV light.

Unopened paint

A typical can of glow in the dark paint will be good for up to three years on average.

As long as the paint is not exposed to sunlight, the phosphors will remain in good shape for up to five years with high-quality brands.

Paint after application

On a good, smooth surface, night glow paint may last up to 10 years.

If you add a clear coat sealer that helps prevent the phosphors from breaking down, then the lifespan may increase to 12 years.

However, at some point, it will begin to fade.

Paint after recharging it once

When you first charge the paint with sunlight, it should glow in the dark for up to four hours.

This means that if you put an object with glow in the dark paint outdoors, you will need to keep it out for the time recommended by the manufacturer of the paint.


How to Charge Glow in the Dark Paint?

Properly charging your paint is important so that it does give off that eerie glow.

Here are a few ways by which it can be done.

1- Sunlight or Solar Power:

Many people have this mind, whether they can actually use solar power to charge glow in the dark paint or not.

But believe me, it’s pretty simple and it does work. You just need to place the object that has glow in the dark paint outdoors in the sunlight for three to four hours.

That should fully charge the paint so that it will glow about that long at night. There are other methods you can use to charge the paint as well.

2- Artificial Light:

Admittedly, artificial light does not have nearly as much UV light, which means that sometimes it will work and sometimes it will not.

LEDs, for example, will probably not work, especially on an invisible glow in the dark paint that is meant to be charged by sunlight.

Cheap or even average glowing paint will probably not work at all when charged in this manner.

You should always check the instructions on the side of the paint before purchasing.

That will tell you what is needed to charge it and how long you should expect it to last.


Can I Use Luminous Wall Paint Outdoors?

Absolutely you can use glow in the dark wall paint outdoors. In fact, it is designed to be charged by the UV rays of the sun.

This means that you can cover your exterior walls or objects with paint and watch them glow at night.

There are some items that you may want to see at night, such as the edge of sidewalks, the concrete driveway, or objects that are suspended and can be run into accidentally.

By using glow paint on them, you can easily see and avoid them at night.

Few Other Creative Uses To Use The Glow Paint Outdoors

There are many ways to use glow in the dark or UV paint creatively outdoors as well.

If you do not want to use glow in the dark paint year-round (on your walls) you may use it only for certain times of the year, such as Halloween.

Halloween is the holiday most commonly associated with glow paint, although Christmas is another bright, colorful holiday when it can be used.

You can create many spooky ghosts and monsters using this type of paint on the body. Or to spray paint specific objects for art and craftworks.

Keep in mind that if the use is temporary, then you may want to use water-based paints that can easily wash off.

Or, you can purchase paper or other temporary covers so they can be painted and then removed when no longer needed.


Tips for Choosing The Best Glow in the Dark Paint

Well, when buying from the market there is no hard and fast guideline for choosing the best glow paint since it will depend on how you want to use it.

A few things that you may need to consider are:

a) Usage:

The first tip is that if you want the paint to be permanent (or at least longest-lasting like Aurora), use an acrylic-based version that is waterproof.

If you just want it to be temporary (like body paint), then a water-based version is recommended.

b) Colors:

While blue, orange, and green are the most common colors, you can find many others (like invisible) when searching for the right glow in the dark paint.

This means that before you start your search, it’s best to know what you want.

c) Use Tubes:

While glow in the dark spray cans has their uses, it’s generally easier to fill tubes with the paint so you can apply it the way that you want.

You can even purchase a set of tubes specifically for painted walls which is quite affordable.

Can You Make a DIY Glow in the Dark Paint at Home?

Do you want to make some really cool glow in the dark paint but you’re just not sure how it’s done?

Well, you’re in luck because it’s actually relatively simple and we have two different options that you can use.

All you’re going to have to do is decide which one of these options you like best and just get going.

The first method to make DIY glow in the dark paint is one that requires a little more specialized ingredients, but it’s still going to be easy to get through.

The second is going to use ingredients that you likely already have lying around your house anyway.

1- Using Phosphorescent Powder

First up, let’s look at the most common method used to create a glow in the dark paint.

It involves something called a phosphorescent powder, which is basically glow-in-the-dark powder.

You can actually buy them just about anywhere and they come in different looks and colors.

If you choose a large particle pack you’ll get a bright color with a speckled look.

Smaller particle packs create a less vibrant glow but look more smooth when finished.

You’ll also need to choose a paint that you’re going to use as the base for your phosphorescent powder.

Also, make sure that the paint and the powder that you choose are going to be compatible.

An acrylic gel is great for paint that you want to appear invisible when the lights are on. Acrylic or tempera is great if you want to have a color.

  1. Mix 5 parts paint to 1-part powder in a small bowl or container
  2. Stir together until well mixed (mixture will not dissolve together)
  3. Paint your walls with your freshly prepared luminous paint

2- Using a Highlighter and Water

One simple method of getting UV paint in a relatively unique (but inexpensive) way, is to use a highlighter and some water.

This method is actually really simple because you’re going to use just a few basic household ingredients.

You choose a highlighter that you like the color of and get started.

  1. Remove the felt strip from the inside of a highlighter.
  2. Put the felt strip into a bowl or small container and run water over it until the color has all bled out.
  3. Mix ½ cup of white cornstarch with the water until the cornstarch dissolves.
  4. Add a small amount of food coloring to get the color that you want.
  5. Paint your walls with your homemade UV paint

You can use it to paint the entire wall in your space, to paint patterns, or for anything else that you like.

Keep in mind that you’re not going to have quite the same quality with this type of glow wall paint as you will with the one that you created with phosphorescent powder, but it’s still going to look cool.

Related FAQs

Can You Clear Coat Over Glow Paint?

It is possible to coat over UV glow paint, but you will need to be sure to completely cover it with at least two to three clear coats.

This is because the phosphors in the invisible glow in the dark paint may still receive enough light to obtain a charge and glow behind the new paint.

So, you will need to add extra coats to ensure that the phosphors are totally covered.

Is Glow in the Dark Wall Paint Safe for Kids?

Glow in the dark paint is as safe as any other paint that comes into contact with kids.

This is because the phosphors themselves are harmless as long as they are not ingested, just like the toxic elements that are part of virtually all manufactured paints.

There are green or environmentally friendly paints on the market, but the general advice is that kids can paint with relative safety using the glow in the dark versions as long as they do not ingest the paint and clean up afterward.

What are the Safety Measures You Need to Follow?

It is recommended that with any paint you use gloves, goggles or eye protection, and a mask when applying paint from a can.

You also need to be in a well-ventilated area that will disperse any toxic or unwanted elements that leak into the air.

Be sure to clean up afterward to remove all the paint from your clothes and skin.

Using small amounts of glow in the dark paint, such as from spray cans, for example, may not need as much protection.

However, like any paint, they need to be applied with care.

Once the paint dries, it is like any other paint in terms of its possible danger to children and adults.

Is Fluorescent Paint and Glowing Wall Paint the Same?

Many times, people who want to use glow paints for walls (or make-up) find something known as UV or fluorescent products that are different from the so-called glow in the dark paints.

In general UV/fluorescent paints are usually triggered by long-wave ultraviolet (UV) radiation or black light in the room.

This means Fluorescent paints do not glow in the dark, but it only works intensely under fluorescent black lights.

Whereas on the other hand, glow-in-the-dark paints may work without a blacklight.

Simply saying, UV glow paints may fluoresce under black light but fluorescent paint does not shine in the dark.

The Bottom Line

Glow in the dark paint has gained some popularity in recent years, despite the fact that it can be expensive.

It’s perfect for wall murals and painting specific objects, and they even have practical uses as well.

So why not try them out and have fun when you are just planning to renovate your dream home.
