Polyurethane VS Epoxy: What’s the Real Difference


Unless you’re a flooring specialist, you likely don’t understand the differences between polyurethane and epoxy coatings. Both types can be used as a coating for concrete floors, but there are major differences between the two that should be recognized. Before diving into the differences, though, here’s a look at the benefits both of these coatings have when used on concrete floors.

  • Light reflective
  • Easy to clean
  • Long-lasting

Epoxy vs Polyurethane Floor Coating

Epoxy floor coating is a thermosetting polymer. It can be purchased in three different formulations: water-based, solvent-based, 100 percent solid. Because each of these formulations is different, they lead to varying degrees of thickness. As to be expected, the thicker the final coating, the more durable it will be. All formulas of epoxy are easy to apply and bond extremely well with concrete. If you’re looking for a coating that provides optimal thickness, you’ll want to go with the 100 percent solid.

Polyurethane floor coating isn’t near as thick as epoxy floor coating, yet it is much more flexible. Because of this, it has a higher resistant to impact, which is paramount when heavy furniture and equipment is going to be used. Before siding with polyurethane coating, though, it’s paramount to understand that the bonding capability of this coating isn’t near as strong as epoxy. Still yet, it does handle temperature changes better as well as high levels of humidity.

What type of coating does your concrete floor need?

Truth is, to get maximum protection for concrete floors, both types of coatings should be used together. Regardless of the coating that you choose, though, it’s imperative that the application process be carried out as instructed and that the concrete be thoroughly cleaned before any coating is applied. If the concrete is not clean, the bonding agents in these coatings won’t be as strong.

If you’re not sure which coating will work best for you, you can always speak with a local flooring specialist. This person can also teach you about the many patterns and final results that can be achieved when using concrete floor coatings. You can literally transform a regular warehouse into a masterpiece of an office building or workspace, and all it takes is knowing how to apply these coatings in the right way.
