Epoxy vs. Polyurethane Garage Floors
Both polyurethane and epoxy coatings are recommended by contractors for garage floors. Both of these coatings are available from Sundek and can protect the floor from damage, oils, chemicals, wear, and stains. Each is easy to clean, long-lasting, and reflects light, making it hard to choose between them. In many cases, clients turn to their contractors for advice when making a decision, the best way to get a great garage floor is by combining these two products. Take a look at the differences between them and benefits of each.
Benefits of Epoxy Coating
Epoxy coatings are specifically designed for garages as well as industrial or commercial spaces and workshops. There are several slight variations of this coating, including a few major options from Sundek, such as SunEpoxy 54, which is ideal for lighter uses like residential garage floors. Because there are multiple types of epoxy coatings (100 percent solids, solvent based, and water based), there is a product for every situation. The system is easy to apply, and it bonds very well to concrete when it is properly prepared. For a top formula, opt for SunEpoxy 100, which is made from 100 percent solids. This formula creates a surface that is extremely hard and resistant to impacts.
Benefits of Polyurethane Coating
Polyurethane is a thermosetting polymer available in several different formulas. Contractors typically recommend aliphatic polyurethane for garage floors out of the available options for this type of coating. The coating isn’t adjustable like epoxy coatings are, and it will only be between 2 and 3 millimeters thick despite being 60 percent to 70 percent solids. This coating excels in terms of flexibility, which lets it absorb impacts better than it would otherwise be able to. Polyurethane coating also offers better chemical and solvent resistance than epoxy ones.
So in summary, epoxies are hard and durable and adhere well so therefor are ideal for the primer and base coats of a garage floor, while polyurethanes are excellent for abrasion and chemical resistance and are perfect for use as the top coat of the floor system. The combination of these will make for a top quality garage floor coating.
