how thick is epoxy floor paint?

I want to coat my garage floor, but I’m unsure how thick epoxy should be. I’ve heard conflicting information about epoxy floor thickness and the differences between concrete epoxy, polyurethane, and self-leveling epoxy.

This article will help you understand how to measure the thickness of a floor coating and how to compare different types of epoxies so you can make an informed decision when choosing a new coating for your project.

How thick is an epoxy floor coating?

The thickness of your epoxy floor coating will vary depending on the brand and application method. The most common thicknesses of epoxy floor coatings are 1/16 inch, 1/8 inch, and ¼ inch.

If you are interested in a thick coat of epoxy (1/16” or more), check out our TopCoat Epoxy Floor Paint selection.

With a minimum coverage rate of 40 square feet per gallon, TopCoat is perfect for large projects where durability and resilience are key priorities.

For those looking for a thinner application (1/8” or less), we recommend starting with either Rust-Oleum Specialty Epoxy Concrete Coating or Zinsser Concrete Floor Paint Spray Kit.

Both products come with easy-to-use spray nozzles that allow you to apply an even layer without wasting any product!

How is epoxy floor thickness measured?

The thickness of epoxy floor paint is measured in mils. A mil is equal to 0.001 inches, or 1/1000th of an inch (1/0.001).

While it’s less commonly used, you may also see epoxy floor paint described by its thickness in microns; this is equivalent to 1/1000th of a millimeter (1/0.000001).

While most people are familiar with the way paints are measured by ounces or gallons, epoxy floor paint measurements tend to be given in these alternative units:

  • Mils (1 mill = 0.001″)
  • Microns (1 micron = 1 millionth of a meter)

How thick is self leveling epoxy?

You may have heard that self-leveling epoxies are 1/8″ thick and polyurethanes are 1/4″ thick. This is true, but there are other factors to consider when deciding which floor coating is right for you.

Self-leveling epoxy and polyurethanes both dry via an exothermic reaction, which means they heat up as they cure and can burn your skin if touched before drying.

Because of this potential for skin burns, it’s important to wear gloves and ventilate the area well when working with either type of coating.

Is epoxy thicker than polyurethane?

The answer is that epoxy is thicker than polyurethane, but that doesn’t mean it’s any more durable or resistant to water.

Polyurethane starts out as a liquid, then hardens when exposed to air and sunlight. It’s extremely flexible, which means it can be applied over uneven surfaces without cracking or chipping off in places where there are gaps between floorboards or tiles.

Epoxy does not have this flexibility and will crack if applied over anything other than perfectly smooth floors, so it’s usually used on floors that are already level (like concrete).

HOW LONG DOES A epoxy floor last?

Epoxy floor paint is more durable than polyurethane and will last even longer if applied correctly. Epoxy floor paints are extremely resistant to moisture, chemicals and abrasion.

Because of this, epoxy can be used in a wide variety of applications including residential, commercial, and industrial settings.

Depending on the application method and preparation, epoxy coating can last as long as 10 years or more before needing to be reapplied again.

Which epoxy floor coating is the best?

Epoxy flooring is the most durable and resilient option for your business. It can handle heavy machinery, constant foot traffic, and even extreme heat or cold.

If you’re looking for a floor that will last a long time and still look great when it comes time to sell your building, epoxy floors are the way to go.

Epoxy flooring is also more expensive than other options like vinyl or carpeting—but if you want something that will last decades, then this might be worth it for you!

On top of that, applying epoxy requires more labor than other types of products: The application process involves using solvents to clean off any dirt or oil from the concrete before applying two coats of micro-fine resin over an entire area—which means that there’s much more work involved in these types of installations than with other materials such as linoleum or carpeting (although these may require periodic maintenance).

How thick should resin floor be?

The thickness of epoxy floor paint depends on several factors. The type of floor and the type of resin will influence your decision as well as the type of paint you choose.

As a general rule, however, it’s recommended that you apply 5-10 mils of coating over concrete if you have an existing floor.

This amount should be enough to cover cracks, holes, and unevenness on the surface. If you’re working with a new surface then 1 or 2 mils would suffice for most applications.

How thick is resin floor?

Resin floor is 1/8″ thick. and Epoxy floor paint is usually 1/8″ to 1/4″. Polyurethane flooring can be anywhere from 1/8″ to 1/4″, but typically ranges around 3/16″.

That makes resin flooring thicker than polyurethane and thinner than epoxy.


So, in summary, we can see that epoxy floor paint is a top-rated product that has many advantages. The main one being it’s durability and longevity. It can last up to 20 years!

In addition, epoxy is an environmentally friendly material that doesn’t contain chemicals like polyurethane or asphalt-based products do.
