What is the Difference Between Polyurethane and Polycrylic?

Polyurethane and polycrylic are both protective substances used for wood projects, but they have some differences:

1. Base: Polyurethane is oil-based, while polycrylic is water-based.
2. Durability: Polycrylic is not as durable as polyurethane and is meant to be used only on interior surfaces such as cabinets, furniture, and trim. Polyurethane is more suitable for surfaces that are subject to a lot of wear or exposure to water.
3. Appearance: Oil-based polyurethane imparts a slight amber tone to the wood, while water-based polyurethane dries clear. Polycrylic is available in various finishes, giving it a slight edge over polyurethane in terms of appearance.
4. Application: Polycrylic has a thinner consistency than polyurethane, making it prone to drips and sags when applied to vertical surfaces. However, it dries faster than polyurethane, which can lead to brush or lap marks if not applied carefully.
5. Tinting vs Shining: Oil-based polyurethane dries with a glimmer that is tinted with a warm tone, while water-based polyurethane dries clear. Polycrylic tends to yellow slightly over time, making it better suited for lighter woods.
6. Clean up: Polycrylic is less toxic than polyurethane and cleans up with soap and water.
7. Cost: Polycrylic has a slight advantage in terms of cost, as it is generally less expensive than oil-based polyurethane. However, water-based polyurethane products can be found at a comparable price to polycrylic.

When choosing between polyurethane and polycrylic, consider factors such as the project's intended use, location, desired appearance, and the wood's natural color. Polycrylic is generally better suited for interior projects like cabinets, furniture, and trim, while polyurethane is more versatile and suitable for a wider range of applications.

Comparative Table: Polyurethane vs Polycrylic

Here is a table comparing the differences between polyurethane and polycrylic:

In summary, polyurethane is more durable and suitable for high-traffic areas, while polycrylic is a less durable, water-based product that is less toxic and has a faster drying time. Polyurethane can impart a slight amber tone to the wood, whereas polycrylic may get a milky or cloudy cast over time. Both products can be cleaned with soap and warm water, and they are available in various sheens.
