Is Latex Paint Flammable?

“Latex-based paint” is a generic one implemented to classify “water-based coating emulsions” manufactured with synthetic acrylic binders. They are applied as protective coating layers to prevent corrosion on metallic substrates.

Acrylic paints are made up of chemicals, whereas latex paints are based on water. The ability of latex paint to be easily removed from surfaces and paintbrushes is one of the benefits of using latex paint. It also indicates that this paint has a much thinner consistency, which allows it to dry in a much shorter amount of time.

Latex paint is exceptionally long-lasting and resilient against scuffs and scratches. Furthermore, it offers improved reliability, adhesion, and stability on the surface of the protected metal. Perhaps you won’t believe me when I say this, but latex paint is not flammable. 

Although latex paint has several drawbacks, including being sensitive to temperature changes, shrinking rapidly, and requiring a primer before it can be applied, latex paint is not flammable.

If you still have doubts, the following reasons will prove that it’s not flammable.

6 Reasons Why Latex Paint isn’t Flammable

1. There’s no latex in latex paint.

The title “latex paint” can be misleading in several different ways. Although it may have the appearance of latex paint, it’s not made of latex and does not contain any latex protein. Acrylic resin and polymers are the two main components of latex paint.

The term “latex paint” does not refer to a specific type of paint; instead, it’s used to refer to any water-based paint.

2. Latex is colored with titanium dioxide that isn’t flammable

In the coatings industry, titanium dioxide, known as TiO2, is considered the most important white pigment. When incorporated into a coating, it confers whiteness, brightness, and opacity, contributing to its widespread application because it effectively scatters visible light.

Titanium dioxide, which imparts white and brilliant hues to water-based latex paint, increases the coating’s mechanical strength and corrosion resistance. It reduces the coating’s permeability and the amount of water passing through it, making it nonflammable and combustible.

3. Latex paint has no flashpoints

The fact that latex paint is water-based and does not have a flash point higher than 93 degrees Celsius eliminates any possibility that it could catch fire.

Latex paint has a lower flash point than oil-based paint. There is a very remote possibility that a fire, blast, or fume could spread to an ignition source and cause damage to your shop; however, this possibility is extremely low.

4. Latex paint uses non-flammable isothiazolinone preservatives

Isothiazolinones are used as a preservative in various consumer products worldwide, including cleansers, hair products, and water-based paint.

These products are available in the United States. Because of the wide range of stability and effectiveness that isothiazolinones offer, they are frequently used in combination with other formulations. Isothiazolinones are commonly used to extend water-based coatings’ lifespan and prevent them from becoming mildewed.

5. Latex paint isn’t combustible when wet or dry

As was discussed in reason three, latex paint does not have a flashpoint, and the fact that it’s water-based means that it cannot catch fire even when wet and cold. Titanium dioxide, found in latex paint, helps the paint retain its strength even after it has dried.

It is, therefore, unnecessary to worry about whether your latex paint is wet or dry before exposing it to things that will cause it to catch fire. Nevertheless, it’s best to choose the side of carefulness and always take precautions.

6. Latex paint isn’t flammable when applied on a non-combustible surface

If something is said to be non-combustible, it cannot start a fire even if it’s put in an environment with a flame.

Any non-combustible surface, including steel, masonry, ceramics, and insulating materials such as fiberglass or mineral wool insulation, can be painted with latex paint without fear of damaging the surface.

The use of latex paint on a surface serves as a surface sealer, thereby preventing the spread of mold and other fungi. However, it must be painted on a dry surface to achieve the best results. This multipurpose painting medium can be applied to various surfaces, including those that are not combustible.


After reading this, you should better understand the factors that make it impossible for latex paint to catch fire. In addition to the fact that it does not have a flashpoint and is water-based, it also contains substances that make it resistant to fire. These substances contribute to the overall fire resistance of the product.

If you are concerned that the latex paint might get wet and then after it has dried, it might start a fire, then you can put those worries to rest because it won’t happen. In its dried state, latex paint has a rubbery consistency and does not, under any circumstances, pose a fire hazard.

This is because latex paints do not contain any flammable solvents, and as a result, they do not produce any flammable vapor.

You shouldn’t be afraid to use latex paint on any surface with metal, stones, or glass because it can be used on non-combustible surfaces, which is another advantage of this type of paint.

Even though latex paint is not flammable, other types of paint are considered flammable and combustible substances. As a result, all types of paint, including latex paint, should be kept in a flammable storage cabinet whenever possible to ensure the safety of everyone in the area.

It’s possible that, at first, you were perplexed by the fact that the paint is called latex paint even though it’s not flammable.

However, there are times when the paint does not live up to its name. Because of this, it’s always essential to know about paints, how to use them, and their substances.

Since latex paint is not combustible, you do not need to be concerned about whether or not to use it anymore now that you know this information. The safe latex material has fire resistance and won’t catch anything else in the area ablaze.
