Oil-Based Polyurethane

Oil-based finishes offer durable, highly resistant solutions. However, their oil-based structure creates an even more durable composition—but with stronger odors compared to water-based finishes. They also come in various sheens, but instead of painting clear, they leave a slight amber tinge, which can turn even more yellow over time. Oil-based polyurethane usually takes a whole day to dry, but it only requires one to two coats. Unlike water-based finishes, oil-based finishes consist of mineral solvents or petroleum as a base to hold the polyurethane solids. This base creates a thicker mixture with denser properties and a more pigmented stain. Many woodworkers like to use oil-based finishes to seal their final products, using the amber tint to enhance the wood’s colors and natural markings. Plus, the oil composition creates water-resistance, further optimizing the wood’s durability and longevity.
