Preparing the Painting

Once you’ve applied the sealer, let it dry for at least 24 hours. Make sure the painting is in a well-ventilated area and away from direct sunlight.

Finishing Touches

Once the sealer is dry, you’re almost done! Use a soft, clean cloth to lightly buff the painting and remove any excess sealer. This will give the painting a more even finish and will help protect it from dust, dirt, and other debris.
