How can I effectively apply water-based polyurethane over an oil stain for a durable and long-lasting finish?

Answer 1

To effectively apply water-based polyurethane over an oil stain for a durable and long-lasting finish, follow these steps:

1. Ensure the oil stain is completely dry before applying the water-based polyurethane.
2. Lightly sand the stained surface to create a smooth and even base for the polyurethane.
3. Apply a thin and even coat of water-based polyurethane using a high-quality brush or applicator.
4. Allow the first coat to dry completely according to the manufacturer's instructions.
5. Lightly sand the surface again before applying subsequent coats of polyurethane.
6. Apply multiple thin coats of water-based polyurethane, allowing each coat to dry fully before applying the next.
7. Sand lightly between coats for a smooth finish.
8. Follow the recommended drying and curing times for the polyurethane to ensure a durable and long-lasting finish.
