Listed below are some facts about both epoxy and polyurethane coatings to consider before deciding which one to use.
- Polyurethane has great abrasion and resistance. However, it is not ideal for direct application over concrete. Ideally, it should be applied over an epoxy primer.
- The working pot life is usually longer than epoxy and should not be applied more than 3 mils thick.
- Polyurethanes do NOT provide the best solution in filling cracks and concrete defects. Whereas epoxy is dynamic with changes in depth and has a much better chemical makeup to level uneven surfaces.
- Epoxy coatings are available in various thicknesses, which makes it a customizable product for specific areas and projects.
- Both epoxy and polyurethane are available in a matte or high-gloss finish.
- Epoxy coatings do not have UV stabilizers and therefore will start to yellow over time when exposed to sunlight.
