Polycrylic Vs Polyurethane: Which One Is Right For My Project?

Polyurethane and Polycrylic are both types of clear finishes used to protect and enhance the appearance of wood surfaces. While they sound similar they have some key differences and it's important to know which one is right for your project.

Chemical Composition:

• Polyurethane: It is a synthetic resin that comes in oil-based and water-based forms. Oil-based polyurethane tends to have an amber hue that can darken over time, while water-based polyurethane remains clearer.

• Polycrylic: This is a water-based finish and is essentially a type of acrylic.

Color and Clarity:

• Polyurethane: Oil-based polyurethane can add an amber tint to the wood, which might be desirable for some projects. Water-based polyurethane is clearer and tends to maintain the natural color of the wood more effectively.

• Polycrylic: It is clear and does not typically add any color or amber tint to the wood. It is known for preserving the natural appearance of light-colored woods.

Odor and Drying Time:

• Polyurethane: Oil-based polyurethane has a strong odor and tends to take longer to dry. Water-based polyurethane has a milder odor and dries faster.

• Polycrylic: It has a milder odor compared to oil-based polyurethane and dries relatively quickly.

Durability:

• Polyurethane: Generally, oil-based polyurethane is considered more durable and provides a tougher finish. It can withstand heavy use and is often recommended for high-traffic areas such as wood floors, doors, kitchen cabinets or dining tables. Water-based polyurethane is ideal for projects like desks, side tables, bookcases, or light wood or white painted furniture.

• Polycrylic: While durable, it may not be as resistant to chemicals and heat as oil-based polyurethane. It is suitable for lighter-duty projects and areas with less exposure to heat and moisture like picture frames, side tables, smaller furniture pieces.

Application and Clean Up:

• Polyurethane: Oil-based polyurethane requires mineral spirits for cleanup and can be more challenging to clean. Water-based polyurethane is easier to clean with water.

• Polycrylic: Being water-based, it is easy to clean up with water.

When choosing between polyurethane and polycrylic, consider the specific requirements of your project, including the desired color, durability, and ease of application. Both finishes have their advantages, and the choice often depends on personal preferences and the nature of the woodworking project. I hope this article helps you determine which one is right for your project!
