Typical Epoxy Floor Thickness

The epoxy’s thickness can be as low as 0.01 inches and as high as 0.25 inches. These are called “thin films” and do not provide very good protection for the surface underneath. But, they are great for decorative purposes. The most common thickness used for a full epoxy flooring system are:

  • 1 / 4 inches
  • 1 / 8 inches
  • 1 / 16 inches

The decision to apply a base coat and top coat can also influence the overall thickness of epoxy flooring.

How Thick Your Epoxy Floors Should Be?

We can’t estimate how thick epoxy flooring is required as it depends on many factors. Generally speaking, thin epoxy coatings are used for floors that see limited foot traffic and do not need an extreme level of protection. Thin coatings are also used on a surface that needs repair but only has minor damages. Industrial/commercial floors need a more epoxy coating thickness. The main factors you should consider when deciding how thick epoxy floors should be are:

1. Application Areas

Floors in different places need a different level of strength & resistance. Residential floors see less foot traffic compared to commercial floors. Industrial floors have to withstand heavy equipment and vehicles. It means commercial and industrial floors need a more epoxy flooring thickness than residential ones. Places like the pharmaceutical industry and chemical laboratories need a more epoxy coating thickness for better chemical resistance so that dangerous chemicals don’t damage the surface underneath.

2. Damage In The Surface

Epoxy coating is also used to repair damaged surfaces. When big cracks and divots are in the concrete floor, you need a thicker floor coating to make the flooring system durable. Minor cracks and scratches can be fixed using a thinner coating. 

3. Floor Surroundings

If you want to level your floor with something in the surrounding, it can also influence your decision when choosing the epoxy floor thickness. On certain floors, when they are too high, it can be harder to shut down doors. Consider that when choosing the epoxy floor thickness.

Thin Vs Thick Epoxy Coatings

Pros of Thick Epoxy Coatings

thin vs thick epoxy coating

Thick epoxy coatings provide better resistance to everything when compared to thin epoxy coatings. This makes them extremely durable. Thin epoxy coatings may not be as durable but they are still more durable than most other flooring options. The scratches will never penetrate the surface when you have a thick coating. Such issues may occur when you have a thin coating. Even when you have deep holes in the existing concrete floor, applying the thick epoxy coating will make the flooring system durable even without replacing the damaged floors.

Cons of Thick Epoxy Coatings

Thick epoxy flooring is generally more expensive than thinner coatings or other options. Also, installing thick epoxy flooring is more complex and requires professional help. Since the epoxy layers are thicker, it takes a longer curing time, which may cause you inconvenience.

Pros of Thin Epoxy Coatings

Thin epoxy coating has also some benefits. It is not hard to figure out that thin coatings are less expensive than thick epoxy coatings. They are also easier to install and have a shorter installation process. There is also less chance of mistakes when applying thin coatings. So, you can apply thin epoxy coatings by yourself. But, you’ll most probably need the help of professionals to install thick coatings.

Cons of Thin Epoxy Coatings

One of the significant problems of thin epoxy flooring is its durability is lower than thicker ones. Also, the thin layers are more prone to scratching or peeling, especially in high-traffic areas. The impact and chemical resistance of thin epoxy flooring is also lower compared to thick epoxy flooring. Also, it’s hard to achieve a perfectly smooth finish and change design options.

Application Areas Of Thin Epoxy Coatings

Thin epoxy coatings are mostly used low traffic areas that face minimal adversities. This mainly includes residential spaces like living rooms, kitchens, hallways, etc. Most countertops also use thin coatings. They have enough strength to handle adversities and still be very durable in these types of spaces. 

Thin coatings can also be used in industrial and commercial spaces when you already have a strong flooring system underneath. In that case, many people use thin epoxy coatings mainly to make the floor attractive and easy to clean. They can also be used in electronic centers that need anti-static coating on their floors.

Application Areas Of Thick Epoxy Coatings

Thick epoxy coatings are used in areas that need better impact resistance. Warehouses, manufacturing facilities, etc are the best places to apply thick epoxy coatings. They can easily handle heavy vehicles and equipment without causing any damage to the floor. The pharmaceutical industry, food industry, etc also need thicker coatings for better chemical resistance. 

Commercial spaces with high foot traffic, like public bathrooms, sports facilities, theatres, etc., also need thicker epoxy floor coatings. You can also use a thicker coating if the existing floor surface is lower than it should be.

How To Apply Thick Epoxy Coatings

To apply a thick epoxy coating, prepare the surface like a regular one. Make sure the surface is clean and free from any cracks or damages. Consider applying a primer for adhesion and correctly mixing the epoxy resin and hardener.

Some people may have the misconception that applying thick epoxy coating involves pouring more materials at once. But, that’s not the case. If you pour too much epoxy at once, it may not cure properly and can also create issues like bubble formation and you’ll not get the desired floor finish. Instead, you have to apply multiple layers of epoxy floor coating.


The epoxy floor thickness plays a vital role in determining the durability and performance of the floor. To decide how thick epoxy flooring is required, you should consider the factors like foot traffic and the floor surroundings. A thicker epoxy flooring offers higher durability, whereas the curing time of thinner epoxy flooring is less.
While choosing epoxy floor thickness, be careful of the requirements of the environment in which the flooring system will be installed. I hope this blog answers all your questions related to epoxy floor thickness. If you are still confused about how thick epoxy flooring should be, you can always contact an epoxy flooring specialist for advice.
