Whether your project is home improvement or construction management, using epoxy paint could be worth the move. Epoxy paints are made from epoxy coatings.

They have wide applications for different building parts, such as the floor, automotive, marine, and industrial applications.

You may ask that its unique components are epoxy paint oil based. Epoxy paints are of different types, which could either be oil or water-based. It usually contains two parts, the epoxy resin, and the hardener, combined in different proportions to suit the particular application.

Thus, the formulation of epoxy paints, either oil-based or water-based, depends on their performance requirements and usage.

This article will clearly explain what epoxy spray paint is used for and if epoxy paint is oil-based. Also, you will learn to know when epoxy is bad. Keep reading.

What Is Epoxy Spray Paint Used For?

Epoxy spray paints have wide usages in floor coatings, such as on the patio, garage, and basement floors. Also, their great resistance to acids, alkalis, and water makes them suitable for steel and concrete coatings.

The production of epoxy paints is through the combination of epoxy resin and a hardener. This results in a coating that adheres strongly to different surfaces. The presence of epoxy resins accounts for the low volatility of spray paints. Hence, you have a paint that is environmentally friendly with less volatile organic compounds (VOCs).

Epoxy Spray Paint

Additionally, epoxy spray paint produces a finish that is solvent-resistant and tough for decks, countertops, and floors. The coating is highly durable as they are resistant to chemicals, scratches, stains, and spills.

Generally, the epoxy coating doesn’t just dry. Rather it cures. This account for its usage on concrete floors as it seals off every porosity making the surface water resistance

Steps on Using epoxy Spray paints

You can conveniently apply epoxy spray paints on smaller surfaces and projects. The use of spray gives a better finish and strong adhesion than a normal painting with rollers. Also, you will get that perfect covering resistant to scratches, dirt, grease, and chemicals.

Steps On Using Epoxy Spray Paints

Here are the steps on using epoxy spray paint.

1. Spray on clean and dry surfaces

Before using your epoxy spray paint, ensure you prepare the surface to apply the paint. Clean off every dirt and dust on the surface. You can use sandpaper or a wire brush to remove all the rusty parts where it’s rusty. Then, you can wash, rinse and dry the surface.

For woody surfaces, prepare them by freeing them of debris and chips. Avoid applying epoxy spray paint on a wet surface. It would affect its adhesion, making the paint peel and less durable.

2. Read the spray paint instructions.

Most epoxy spray paints have instructions to help you get the best from the paint. While some already have a mixture of hardener and resin in one can, others may not. In the latter case, you must mix the component following the instructions.

However, there are cans that you’ll have to insert a plunger into them through a tube at the bottom. The process will complete the combination of the resin and hardener to give a perfect finish that will cure the surface.

3. Maintain even spraying

Ensure you don’t focus on a particular spot using epoxy spray paint. This will cause the paint to concentrate on the spot and create an uneven finish.

Being thinner than normal paint, the epoxy spray paint sags when it builds heavily on the spot. You should keep moving the spray nozzle evenly throughout the surface.

4. Ensure adequate safety

The inhalation of fumes from epoxy paints can cause some adverse effects on your health. So, you must apply all the safety precautions during the spraying process. For example, keep the room well-ventilated by opening all doors and windows. Also, you should wear an eye google, gloves, and a mask.

5. Avoid storage under extreme temperatures.

Much cold or hotness alters the epoxy spray paint’s shelf life and properties. So, your storage must be at room temperature. The best pattern in using epoxy spray paint is to finish any content you open. This’s because the paint easily hardens to clump within the can with time as the

6. Avoid sunlight

You must avoid using epoxy spray paints for surfaces that directly interact with sun rays. The rays make the paint finish to be dull by losing its glossiness. Hence, the colors would fade or turn yellowish fast. Also, the paint may easily weaken and starts to peel.

So, outdoor uses of epoxy spray paints demand another coating with additional paint for its protection from sunlight.

Is Epoxy Paint Oil Based?

Epoxy paint comes in different types depending on the proportions of its compositions. It could be oil-based, water-based, or 100% solids epoxy. The production of epoxy is from mixing epoxy resin and a hardener.

Irrespective of the type of epoxy paint based on its components, each possesses some unique qualities that distinguish it.

Is Epoxy Paint Oil Based

Oil Based/Solvent Based Epoxy Paint

Planning on a painting project could make you ask; if epoxy paint is oil-based. Epoxy oil-based paint is the type of epoxy paint in which the carrier agent is an organic compound other than water.

Besides the epoxy resin and hardener, the solvent helps to ensure that you can easily apply the paint on any surface. Also, it facilitates the adhesive force of the paint on the surface, thereby improving its durability and glossiness.

Once the hardener and epoxy resin mix, the curing process of the paint will start. The usual pot life (the period for the paint’s hardening) is 30 to 40 minutes without a carrier. Furthermore, the solvent helps to elongate the pot life to about 2 to 3 hours. This will ensure ample time to apply the paint before it hardens.

As the carrier starts to evaporate, the hardening and curing process of the paint begins. This means that the dry film (the paint curing) is thinner than the wet film (the paint application). Dry film is usually half as thick as wet film. So, a dry film of 3 mils had a wet film of 6 mils.

Benefits Of Oil Based Epoxy Paints

Oil-based epoxy paints have been the prominent type for years back. Here are some of its benefits.

  • Oil-based epoxy paints provide glossier and more aesthetic finishes than water-based types.
  • They offer greater performance and durability.
  • The oil-based types are more resistant to chemicals and other environmental effects. Hence, they are suitable for garages and places with increased movements.

What Is The Difference Between Epoxy Paint And Oil-Based Paint?

While oil-based paint contains just an oil carrier that gives it a shiny characteristic, epoxy paint, besides its carries, comprises two other major components. Epoxy paint has a resin and hardener that combines to ensure a curing effect on surfaces.

Here are some of the differences between epoxy paint and oil-based paint.

Epoxy Paint Vs Oil Based Paint
Epoxy Paint vs Oil Based Paint


Oil-based paints comprise substances that make them suitable for surfaces with higher traffic. In addition to its carrier agent, epoxy has two main components, epoxy resin and a hardener. This accounts for the protective capacity of the paint on surfaces.


Though oil-based paint is durable, epoxy paint is more durable than it. The latter provides a coating that is water-proofed as well as resistant to scratches and spills. Also, it’s resistant to chemicals, acids, and alkalis. Moreover, it displays high immunity against mildew and mold attacks.

Aesthetic appearance

An oil-based paint could offer a good and presentable finish when it dries; it’s still incomparable to epoxy paint. The aesthetic beauty of a dried epoxy painting displays a high-quality glossy finish that can last for many years.

How Long Does Epoxy Paint Take To Dry?

Epoxy painting takes at least 12 to 24 hours to dry. The drying period for epoxy paints differs depending on the carrier agent. But, this is different from its complete curing time, which lasts for 7 days.

Depending on its carrier base, your epoxy painting can dry within 12 to 24 hours after painting. Also, other factors that influence the drying time include the percentage composition of solids, the number of coatings you applied, the humidity of the environment, and others.

Epoxy Paint Dry

The water-based types tend to dry faster than the solvent-based ones since the evaporation. This’s because water evaporates faster than most solvent agents in epoxy paints. After 24 hours, you may walk on floors coated with epoxy paint. But you must apply some caution while doing so.

Epoxy Paints Curing Time

The curing time for epoxy paint is different from its drying time though the same factors may influence both processes. The curing period of epoxy paint is when it takes the coating on a surface to harden completely. Knowing the curing time is crucial as it will help you plan your building improvement project.

The curing period for epoxy paint is usually 7 days. Though the surface will dry within 24 hours after its painted, it will still take one week to harden and give you maximum protection on the surface. So, if you need to move some items on the surface, you do that carefully to avoid scraping off the surface. Otherwise, the perfect time is after a week from the painting.

Can You Mix Oil Paint With Epoxy Resin?

Mixing oil paint and epoxy resin will produce messy and tinted resin. In addition, it’s not a recommendable practice as the oil-based pigments may not properly blend with the resin.

Resins are derivatives of oil. Moreover, oil paints are quite thick, making mixing very difficult. Without proper blending, you will get a clumpy combination or create odd films when you paint the mixture on a surface.

Can You Use Epoxy Paint On Drywall?

You can paint drywall with epoxy paint. The painting serves both as a decorative and protective measure for the wall.

The walls within certain areas risk chemical destruction due to their processes. For instance, walls within most industries, hospitals, petrol stations, abattoirs, laboratories, etc., are susceptible to attacks from acids, alkalis, and other substances.

Hence, the best solution for protection and durability is using epoxy paint. Such coatings fortify the walls, leaving them more resistant to chemical attacks.

How Do You Know When Epoxy Is Bad?

Epoxy is bad through some indications, such as the formation of crystals, thickening of the components, odd odor, yellowish coloration, and others.

Epoxy usually comes with an expiration date. Most times, such dates don’t give a true indication of their effectiveness. The best practice is to use epoxy within 6 months once opened and one year when not.

Several factors cause epoxy to be bad before its expiration date. Some of these influencing factors include

  • Storage temperature – When you store epoxy paints at extreme temperatures, it will affect them.
  • Exposure to sunlight – Sunlight is the main contributor to the yellowish discoloration of epoxy paints.
  • Contaminants – Exposing epoxy to a dusty environment can cause contaminants to get into the paint, affecting its characteristics.

Final Verdict

Epoxy paint remains one of the best coatings that have found wide applications long for several years. It is a coating for floors, walls, steel, and other industrial applications. It comprises two major part that accounts for its excellent characteristics, the hardening agent and the epoxy resin.

But is epoxy paint oil based? Epoxy paint comes in oil-based, water-based, and 100% solids epoxy. Irrespective of its carrier, epoxy paint provides maximum protection for different surfaces. Also, it’s resistant to chemicals, scratches, acids, alkalis, spills, and other harsh treatments.
