How Thick Should Your Epoxy Flooring Be

When it comes to flooring your spaces, one of the things you can consider doing is coating the floor with epoxy. It essentially acts like a protective film that adds to the floor’s durability and even adds strength, thus allowing the floor to carry more weight. 

Nevertheless, if you are thinking about coating your floor with epoxy, you will need to consider how thick it will be. That is because the more epoxy you apply, the more you are going to pay for the substance—and you would like not to waste money on extra epoxy that’s unnecessary.

If you are wondering how thick your epoxy floor should be, here are a few examples of epoxy thickness and what they can be used for.


Thin epoxy flooring can range anywhere between 0.1 to 0.2 inches (4 to 6 mm). Not only are they much easier to install, but they work fine in low-traffic floors to keep them looking in perfect condition. Plus, if you were reworking an area of your space and wanted to enhance your floor’s look, a thin layer of epoxy can do the trick.

Keep in mind that a thin layer of epoxy will not do much in terms of durability. While it will still add some strength to the fixture, it will not be much. Therefore, a thin layer of epoxy should only be used in parts of your home that do not experience too much foot traffic.


For places that experience more foot traffic, a thicker coating is essential. The thickness can range from anywhere between 0.4 to an inch of epoxy.

With such a thickness, your floor can maintain its stunning aesthetics while still requiring only minor maintenance, since the epoxy has made everything much more durable. That said, epoxy of these thicknesses is popular with commercial properties because of the high volume of foot traffic.

Extra Thick

What use can there be for anything thicker than an inch of epoxy? These thicknesses will usually be used for spaces that hold industrial equipment. Generally, epoxy here will be around 5 inches (125 mm) thick. This is because environments such as factories not only contain heavy machinery but are prone to accidents, like chemical spills. Aside from that, vehicles will also move around these spaces, while places a lot of stress on the floor.

With that in mind, if you have a similar use to one of your spaces, an extra thick coating of epoxy is essential. These give your floor the durability it needs to resist heavy objects and harmful chemicals. Plus, it makes your floor look nice and clean even with all that action going on, making cleaning the floor a much easier job to do.


With the examples we have given, you now know how thick your epoxy coatings should roughly be depending on the use of the room. To summarize, if your space experiences little to no foot traffic, or you want to enhance the look of your home’s flooring, a thin layer of epoxy coating will do fine. However, if the floor is tread upon a lot and heavy objects continuously move around on its surface, a thicker coating is required to maintain durability and aesthetics. If you are still unsure, we highly recommend that you work with experts to help identify exactly how thick your coatings need to be to offer the perfect balance between cost and utility!
