Acrylic paints are an excellent option for many projects because they’re sturdy and versatile enough to work in most environments. It may be ideal on the interior or exterior of your home, car, or hobby project, depending on how much heat exposure they’ll experience.
Is acrylic paint flammable? Acrylic paint is non-flammable when wet because it is water-based. However, acrylic paint is considered combustible when dry because it turns into a solid plastic polymer.
Oil-based paints such as polyurethane and varnish are flammable. In addition, they also contain hazardous pigments that can cause harm if not disposed of properly.
Due to their versatility, you can work with acrylic paints for various projects that require heat exposure to create beautiful strokes and effects for the painting. But does this imply that they are nonflammable, even when dry? Let’s dive in.
Is Acrylic Paint Flammable When Dry?
Yes, acrylic paint is flammable when dry. When the acrylic paints dry, they become a whole new substance which is essentially a solid plastic polymer.
Now, this substance is considered to be flammable. To be precise, dried acrylics are polymer hydrocarbons that burn easily when exposed to air or oxygen above their ignition temperature.
Moreover, the acrylic paint will eventually be ruined if exposed to high temperatures for too long. The binders in the pigment start flowing and can cause all sorts of problems, such as making the colors non-uniform or creating cracks on top of your painting once you’ve waited enough time for them to dry.
Now, we know that acrylics are nonflammable when they are in their liquid form but are flammable when dried. So, what about another category of acrylics, latex acrylic paints. Are these flammable too?
Is Acrylic Latex Paint Flammable?
Latex paints have been proven to be non-flammable in their liquid state and are safer than solvent-based acrylics like lacquers or enamels due to their water-based composition, making them lower risk for fire hazards. However, it is at a high risk of combustion.
Latex paint is made from a water-soluble base that is mixed with acrylic resin. This particular type of latex, also called rubber-based, has been in use for a long time now as it can be easily cleaned up after painting and doesn’t dry out or cause any damage to surfaces if accidentally spilled on them as oil paints would.
But how can paint be combustible and not flammable?
Difference Between Combustibility And Flammability
Flammable materials ignite at lower temperatures than combustible materials when exposed to an ignition source. This temperature, also known as the flash point, separates flammables and combustibles in combustion risk.
The flash point of flammable materials is below 100°F, and that of combustible materials is above 100°F.
Acrylic acid, which is the substance that makes up acrylic paint in its liquid form, has a low flashpoint of 124°F temperature and an autoignition point 820°F.
What Is Acrylic Paint Made Of?
Latex paint encompasses any type of water-repelling synthetic polymer such as acrylic.
Acrylic paint is a water-based pigment suspended in acrylic polymer emulsion and plasticizers, silicon oils, defoamers, stabilizers, or metal soaps. It requires additional chemicals to mix with water due to its hydrophobic properties.
Therefore, surfactants are introduced that contain molecules on one side, which repel water while attracting another. This allows acrylic paints to be mixed together into latex form without being repelled by liquid before drying out or gathering dust particles, as would happen if left untreated.
These surfactants like sodium dodecyl sulfate lower the surface tension between water and acrylic resins to form paint that can be applied with brushes or rolled onto canvas.
Paints are mainly composed of pigments with binders or resins that help them stick together in large masses like lumps. However, in acrylics, water acts as their solvent (or liquid) while also being able to serve both functions at once by serving up some surfactants.
Are The Fumes Released By Acrylic Paints Flammable?
The type of paint you use on your walls can affect how safe it is. For example, some paints and solvents release toxic or highly flammable fumes, like acetone, which causes a heavy odor in the air. Fortunately, acrylic paint doesn’t pose this risk.
Some of the most dangerous paints and stains have a high risk for fire or explosion. These include oil-based paints, enamels, varnish, lacquer, and colors in spray form, such as an enamel sold in a can. For more information, you can read our article: Is Paint Flammable?
Is Acrylic Enamel Flammable?
Water-based enamel is not flammable by NFPA standards. It has a HMIS rating of 1 and a flashpoint of 201°F. Acrylic enamel is one of the most common types of paint used for automotive surfaces.
Moreover, when acrylic enamel dries out, it leaves behind a smooth surface that shines with a glossy finish. It also forms an exterior layer that’s more resistant to weathering than other paint types you may find in your local hardware store.
Is Acrylic Lacquer Flammable?
Acrylic lacquers are fast-drying and durable paint that produces an even finish. The only drawback is they are highly flammable and toxic like enamels, but their durability makes up for it in some cases.
Examples of places you might see this type of acrylic include automotive finishes, wood furniture stains or varnishes with high gloss effects, etc. Moreover, acrylic urethane enamel paint is the most popular coat for cars because it lasts longer than lacquer and doesn’t put out harmful chemicals into the air.
Characteristics Of Acrylic Paints
1. Least Toxic and Most Versatile
Acrylic paint is the most versatile and least toxic medium out there. Also, it is water-soluble when wet, but because it’s a plastic polymer, it dries into a flexible surface that can hold many layers without disturbing any previous ones. Also, they do not release any toxic fumes when exposed to heat.
2. Dries Quickly
One of the most notable qualities of regular acrylic paint is its fast drying time. This enables an artist to work in multiple successive layers without muddying colors, allowing for more intricate details and a richer texture that can’t be achieved with quicker-drying paints.
3. Large Variety
You can get it in tubes, jars, or small ink bottles – whatever your preference! Acrylics are also available as thick solutions to be used, like oil paints, and thinner versions to work with when layering colors. Regardless of what consistency you prefer, though, make sure that any tube or jar bought has been appropriately sealed so that dried-out acrylic doesn’t ruin all your hard work.

4. Can Be Thinned With Other Mediums
Acrylic paint can be thinned by adding water and other mediums, but you have to use just the right amount, or it will start to break down. Liquid acrylic in ink form is a terrific option for someone who wants very fluid paints. You’ll also need special mediums like flow-medium that make sure your colors don’t become too concentrated later on when painting.
5. Can Be Used Like Oil Paints
Acrylic paints can be used like oil paint in many ways. Although acrylics are known for their bright colors, there are also a lot of other color options that allow you to use them just as you would with oils.
We hope you have got all the knowledge about acrylic paints being flammable or nonflammable in various forms. But what about paints as a whole. Do all paints have the same properties?
Is Paint Flammable?
Is paint flammable? There are both flammable and nonflammable types of paints. For example, some types of paint, like aerosol or oil-based paints and water-based ones, might be considered more volatile than others, such as latex or vinyl-based products that may not pose a risk in this regard.
This being said, water-based paints are completely safe for home use. These paint types won’t catch fire and contain no toxic fumes like oil-based products can. In addition, their liquid form is even less flammable.
