Water-based and oil-based polyurethane are two common types of floor finishes used for hardwood flooring. Both have their advantages and disadvantages, and it is important to understand the differences before choosing which one to use. In this article, we will discuss water-based and oil-based polyurethane floor finishes in detail, their pros and cons, and which situations they are best suited for.
Water-Based Polyurethane Floor Finish
Water-based polyurethane (WBPU) floor finish is a type of finish that is made from water and synthetic resins. It is a clear finish that dries quickly and is odorless. It is also less toxic than oil-based polyurethane and has lower VOCs (volatile organic compounds).
Pros:
- Dries quickly
- Low VOCs
- Less toxic than oil-based polyurethane
- Water cleanup
- Low odor
- Does not yellow over time
Cons:
- Expensive
- Requires more coats than oil-based polyurethane
- Requires more frequent maintenance
- Can raise the grain of the wood
Water-based polyurethane floor finish is best suited for areas that have high traffic, such as living rooms, hallways, and kitchens. It is also ideal for areas that are exposed to direct sunlight, as it does not yellow over time.
Oil-Based Polyurethane Floor Finish
Oil-based polyurethane (OBPU) floor finish is a type of finish that is made from synthetic resins and mineral spirits or petroleum. It is a clear finish that takes longer to dry than water-based polyurethane, but it is more durable and resistant to scratches and abrasions.
Pros:
- Durable
- Scratch-resistant
- Long-lasting
- Affordable
- Requires fewer coats than water-based polyurethane
Cons:
- Strong odor
- High VOCs
- Yellows over time
- Longer drying time
- More toxic than water-based polyurethane
- Requires solvent cleanup
Oil-based polyurethane floor finish is best suited for areas that have low traffic, such as bedrooms, studies, and guest rooms. It is also ideal for areas that are not exposed to direct sunlight, as it tends to yellow over time.
Conclusion
Both water-based and oil-based polyurethane floor finishes have their advantages and disadvantages. Water-based polyurethane is more expensive and requires more coats than oil-based polyurethane, but it is less toxic, has lower VOCs, and does not yellow over time. Oil-based polyurethane is more durable and long-lasting, but it is more toxic, has a strong odor, and tends to yellow over time. When choosing a floor finish, it is important to consider the location of the area to be finished, the amount of traffic it will receive, and the level of sunlight exposure.
