To achieve a durable and long-lasting finish when applying polyurethane over oil-based stain, it is important to follow these best practices:
- Ensure the stain is completely dry before applying polyurethane.
- Sand the stained surface lightly to create a smooth base for the polyurethane.
- Apply thin, even coats of polyurethane, allowing each coat to dry completely before applying the next.
- Sand lightly between coats to promote adhesion and smooth out any imperfections.
- Use a high-quality brush or applicator to minimize brush marks.
- Allow the final coat of polyurethane to cure fully before using the finished surface.
