To effectively apply water-based polyurethane over an oil stain for a durable and long-lasting finish, follow these steps:
- Ensure the oil stain is completely dry before applying the water-based polyurethane.
- Lightly sand the stained surface to create a smooth and even base for the polyurethane.
- Apply a thin and even coat of water-based polyurethane using a high-quality brush or applicator.
- Allow the first coat to dry completely according to the manufacturer's instructions.
- Lightly sand the surface again before applying subsequent coats of polyurethane.
- Apply multiple thin coats of water-based polyurethane, allowing each coat to dry fully before applying the next.
- Sand lightly between coats for a smooth finish.
- Follow the recommended drying and curing times for the polyurethane to ensure a durable and long-lasting finish.
