Steps to Paint Over Spray Paint

Preparation

Ensure the surface is clean and dry. Remove any dirt, grease, or debris.

Lay down drop cloths to protect the surrounding area.

Sanding

Lightly sand the spray-painted surface with medium-grit sandpaper (about 120-150 grit) to create a texture for the new paint to adhere to.

Follow up with fine-grit sandpaper (about 220 grit) to smooth out the surface.

Cleaning

Wipe the sanded surface with a clean cloth to remove dust and debris.

Priming

Apply a coat of primer to the sanded surface. This helps the new paint stick better and can also prevent any bleed-through of the spray paint.

Allow the primer to dry completely according to the manufacturer's instructions.

Once the primer is dry, apply your chosen paint. If using a brush or roller, apply it evenly.

If using spray paint, hold the can about 6-12 inches away and spray in light, even coats.

Allow the first coat to dry, then assess if a second coat is needed.

Finishing

Once the final coat is dry, remove any masking tape and clean up the area.

Tips

If the spray paint is glossy, sanding is especially important to ensure good adhesion.

For large areas, consider using a paint sprayer for a smoother finish.

Always test a small area first to ensure compatibility between the spray paint, primer, and topcoat.

Following these steps should help you achieve a smooth and durable finish over spray paint. Remember, the key to a successful paint job is preparation and attention to detail.

Key Steps Recap:

Ensure surface is clean and dry.

Sand the surface lightly and evenly.

Apply a coat of primer.

Apply your chosen paint in even coats.

Allow each coat to dry thoroughly.
