It cannot be easy to decide between the epoxy coating and polyurethane for the garage floor project. If you have ventured to research each material’s benefits, you know it can get a bit confusing.
Epoxy vs. polyurethane
Both coating products will defend against damage, stains, chemicals, and wear. Each coating is very tough and long-lasting, easy to clean, and light reflective. Depending on the application, they specifically have their advantages. So instead of choosing one or the other, most applications use both.
What is epoxy floor coating?
A thermosetting polymer, epoxy, is available in three formulations, water-based, solvent-based, and 100 percent solids. These materials are used for garage floor coatings and sealers. They provide a wide range of thickness variations, ease of application, VOC considerations, and individual bonding characteristics. Epoxy bonds very strongly to concrete and may be used to resurface weathered out concrete.
The most permanent epoxy coatings are 100 percent solids. These formulations create a remarkably thick, hard, and impact-resistant garage surface. The coating is self-leveling and fills in any hairline floor cracks or other imperfections while providing strong protection. Some options include UV inhibitors, but keep in mind they may still look yellowish after prolonged sun exposure.
What are the advantages of polyurethane?
Similar to epoxy, polyurethane is likewise a high-performance thermosetting polymer coating. It is also referred to as simply urethane, even though polyurethane and urethane are not the same material. If you come across an advertisement for urethane, it is most likely polyurethane.
For garage flooring, aliphatic polyurethane is the best choice. The manufacturer is composed of about 65% solids and is only about three mils thick. Unlike epoxy, polyurethane can’t be adjusted. Yet, aliphatic polyurethane offers more flexibility, greater impact absorption, and abrasion resistance. Polyurethane coating also offers better stability against chemicals.
Also, polyurethane floor coating is more UV stable than epoxy, meaning it won’t turn yellowish with long-term exposure to light. Epoxy is much harder, but polyurethane is a lot more scratch-resistant; it reacts better to humidity and temperature changes.
Even with all of these improvements, epoxy bonds better to concrete, and the thin thickness of polyurethane doesn’t work well at filling in defects.
Which flooring material is the best option?
The general belief is to use both epoxy and polyurethane coating for your garage floor for maximum performance. Whether you hire a professional or do the job yourself, the garage floor epoxy should be used to build thickness, followed by a clear polyurethane topcoat for optimal stability. This process will prevent the epoxy material from yellowing and provide a long-wearing, scratch-resistant coating.
