Both epoxy and polyurethane coatings are used in industrial settings across the globe. Both types of products offer their own set of advantages and considerations, which can make choosing between the two difficult. So here are some facts about both types of finishes to help you decide which is best for your location, epoxy or polyurethane:
- Polyurethane is great for abrasion resistance. However, it has trouble bonding to concrete surfaces.
- Polyurethane is easy to apply and usually has a long pot life. It is rolled on at approximately 2 – 3 mils and is not designed to build any thicker. Polyurethanes are limited in their ability to fill in cracks and other surface defects. Epoxy, which is versatile in the depth that it can be installed, can help to level an uneven floor due to its ability to cure at different thicknesses. In fact, installers can choose the thickness level of epoxy coatings, making these products truly customizable.
- Both epoxy floors and polyurethane floor coatings can be installed with a matte or high shine finish.
- Epoxies are typically 100% solids and give off 0 VOC, polyurethanes have come a long way and can actually be installed with such low VOC present that installation can be performed anywhere without respirators if the right product is selected.
- In the end, both epoxy and polyurethane are great products. Both serve a distinct purpose and actually need to be installed together!
Successful Epoxy Floors
From the points listed above, you realize it is best to use epoxy as a repair, patch and build coat to hide imperfections in the concrete. Then you want to sand the epoxy and install a coat of polyurethane as a protective wear surface over the epoxy coating.
