How To Refill A Fire Extinguisher With Paint?

You should determine whether you will need an extinguisher to store the paint you are going to use to fill a fire extinguisher. Not all paint is hazardous. After you finish decorating your home, you might be able to store your paint tins on shelves in your shed.

More than 80% of household paints are water-based. This means they are not flammable. Double-check your paint cans to make sure they are solvent-based. If so, an extinguisher might be required.

Paint used in a commercial or industrial environment is more likely than paint used in a residential setting. This means that you will need to use a fire extinguisher.

What Fire Extinguishers Are Available?

Flammable paints can be exposed to flammable liquids and fuel in a Class-B fire. This means that dry powder and foam extinguishers as well as CO2 can be used.

It is therefore important to have a good extinguisher in case of a small fire.

Every extinguisher will specify the type of flames it can put out. Double-check any one you have.

Spray paint can also be applied with a dry powder or CO2 extinguisher. Spray paint should be applied in a safe environment.

Storing and Using Flammable Paint

Keep your storage volume to a minimum, as with any flammable substance. Instead of carrying a large load, only carry what you will use at any one time. If it's inevitable, there are other options.

For example, you might use steel flammable storage cupboards. These cabinets are designed to keep the liquid contained within from catching fire for approximately 30 minutes. This gives you ample time to evacuate a building and call the fire department before the flames spread further.

It's possible that the paint you are using is combustible. If this happens, you could be exposed to a vapor which can cause serious health problems.

Make sure that everyone is safe if you use flammable paints within your business. You must ensure that you have the right equipment and that it is maintained in good working order.

Filling a fire extinguisher using paint

Montreal's anarchists have used paint-filled fire extinguishers as a way to resist gentrification and surveillance. These are extremely popular with new artists. Let's take a look at how to fill the fire extinguisher using paint and make a huge spray.

1. Locate the Extinguisher

Find a water-based fire extinguisher. These are available in silver metallic and two sizes.

Both sizes have detachable tops, which are held in place by a nut.

For easy pressurization, the larger capacity 9 L is available. It features a Schrader valve similar to a bike tire. It can be found in many places including offices and residences.

The smaller version, 6 L, requires an air compressor to repressurize. Since it is used to light grease fires, it can only be found in restaurants. It's usually located near the rear exit.

2. Get rid of all water

Cotton gloves are a good choice to avoid leaving prints everywhere. Spray water on the fire extinguisher to ensure that the pressure gauge is at 0 psi. This is something that we do in an alleyway but can also be done in the bathtub.

3. Paint the Fill

Take out the top and the nut.

You can fill the extinguisher to halfway with equal amounts of water and latex paint. This will make a suspension that is balanced and saturated enough to spray.

If you want to make a large spray paint using the fire extinguisher, then you should pay attention to how much water and paint it takes. The paint will be less dense if the water content is higher than the paint.

The same applies to paint that is more dense than water. This paint will cause a mess on the surface where it will be used. Be careful when filling the paint with the extinguisher.

4. Make it a priority to pressurize

Attach the top and tighten it.

You can use a bike pump or a bicycle pump to pushurize the 9 L until it reads 100 PSI.

The 6 L does not have a Schrader valve, so an air compressor is required. These can be purchased at most hardware stores and pawn shops. To connect the compressor tube to the air compressor, remove the hose.

The air compressor should be set at 115 pounds per square inch. You don't need to press the handle of the extinguisher to cause the pressure to rise steadily to 100 psi. If necessary, remove the safety pin and slowly depress the handle. Stop when the pressure reaches 100 psi to prevent paint from getting inside the tube.

Place the safety pin back in its place and duct-tape.

5. Clean

Use a towel soaked with rubbing alcohol to erase fingerprints. To remove any dirt or paint marks, use a towel soaked in rubbing alcohol. This will allow you to work more efficiently and with less stress.


Filling the fire extinguisher with paint is easier than using small spray paint bottles. Smaller bottles require more work and are slower to use. If you are interested in this unique painting technique, please follow the above instructions and have fun with your creations.
