Learn how to apply oil-based polyurethane from start to finish...from preparing bare wood and brushing the first coat to sanding between coats, removing dust nibs, and allowing the final finish to cure properly.
In this complete polyurethane finishing guide, I use a solid white-oak toilet seat to demonstrate the same process you can use on tables, cabinets, furniture, and other woodworking projects.
We’ll cover:
• Choosing the right sanding progression
• Why sharp edges should be softened before finishing
• Finding scratches with a raking light
• Cleaning bare wood with mineral spirits
• Choosing a brush for oil-based polyurethane
• Stirring polyurethane thoroughly from the bottom up
• Applying thin coats and maintaining a wet edge
• Tipping off bubbles and brush marks
• Testing whether polyurethane is dry enough to sand
• Sanding dust nibs and imperfections between coats
• Avoiding sand-through along edges
• Applying an optional 1:1 polyurethane and mineral-spirits wiping coat
• Understanding the difference between dry and fully cured
• Using the paper-bag trick to remove tiny final dust nibs
Always follow the application, drying, recoating, and safety directions provided by the manufacturer of your finish.
