How can I effectively apply polyurethane on top of paint for a durable and long-lasting finish?

Answer 1

To effectively apply polyurethane on top of paint for a durable and long-lasting finish, follow these steps:

1. Ensure the painted surface is clean and dry before applying polyurethane.
2. Sand the painted surface lightly to create a rough texture for better adhesion.
3. Apply a thin coat of polyurethane using a high-quality brush or roller.
4. Allow the first coat to dry completely before applying additional coats.
5. Sand lightly between coats to smooth out any imperfections.
6. Apply multiple thin coats of polyurethane for a strong and durable finish.
7. Allow the final coat to cure fully before using the surface.
