To effectively apply polyurethane on top of paint for a durable and long-lasting finish, follow these steps:
- Ensure the painted surface is clean and dry before applying polyurethane.
- Sand the painted surface lightly to create a rough texture for better adhesion.
- Apply a thin coat of polyurethane using a high-quality brush or roller.
- Allow the first coat to dry completely before applying additional coats.
- Sand lightly between coats to smooth out any imperfections.
- Apply multiple thin coats of polyurethane for a strong and durable finish.
- Allow the final coat to cure fully before using the surface.
