Preparation

Step 1: Clean the Surface

Start by thoroughly cleaning the plastic surface to remove any dirt, grease, or previous coatings. Use soap and water or isopropyl alcohol for best results.

Step 2: Sand the Plastic

Lightly sand the surface with fine-grit sandpaper. This will create a texture for the paint to adhere to, ultimately promoting a better bond.

Step 3: Tape Off Areas

Use painter's tape to cover any areas you do not want to be painted. This ensures clean lines and prevents overspray.

Step 4: Apply Primer (Optional)

Applying a primer designed for plastic can enhance adhesion and improve the final appearance. If you choose this route, make sure the primer is completely dry before proceeding to paint.

Step 5: Spray Painting

Step 6: Finishing Coats

After the base color has dried, consider applying a clear topcoat for added durability and a glossy finish. This step is crucial for items that will be exposed to the elements.

Common Mistakes to Avoid

Finishing Touches
