To effectively apply polyurethane over boiled linseed oil for a durable and protective finish, follow these steps:
- Allow the boiled linseed oil to fully dry and cure for at least 24 hours.
- Lightly sand the surface to ensure adhesion of the polyurethane.
- Apply a thin, even coat of polyurethane using a high-quality brush or applicator.
- Allow the polyurethane to dry completely between coats, typically 2-4 hours.
- Sand lightly between coats for a smooth finish.
- Apply multiple coats of polyurethane for added durability and protection.
- Allow the final coat to cure for at least 24 hours before using the finished surface.
