To successfully paint plastic picture frames, you'll need to properly prepare the surface and use the right type of paint. Here's a step-by-step guide:
1. Preparation is Key
-
Clean the Frame: Thoroughly clean the plastic frame with soap and water to remove any dirt, dust, or grease. Ensure it's completely dry before proceeding.
-
Lightly Sand the Surface: Use fine-grit sandpaper (220 grit or higher) to lightly sand the entire surface of the plastic frame. This creates a slightly rough texture that helps the primer adhere better. This is crucial because plastic is inherently smooth, and paint struggles to grip it.
-
Wipe Away Sanding Dust: After sanding, wipe the frame clean with a tack cloth or a damp cloth to remove all sanding dust.
2. Prime Time
-
Apply a Primer: Use a plastic-specific primer or a multi-surface primer that is designed to adhere to plastic. Apply a thin, even coat of primer to the entire frame. This is arguably the most important step. The primer acts as a bonding agent between the plastic and the paint.
-
Allow Primer to Dry Completely: Let the primer dry completely according to the manufacturer's instructions. This may take several hours or even overnight.
3. Painting the Frame
-
Choose Your Paint: Acrylic paint is generally a good choice for painting plastic picture frames. It's durable, dries quickly, and is available in a wide range of colors. Spray paint formulated for plastic is also an excellent option for a smooth, even finish.
-
Apply Thin Coats: Apply thin, even coats of paint to the frame, allowing each coat to dry completely before applying the next. Multiple thin coats are better than one thick coat, as they are less likely to drip or run.
-
Allow Paint to Dry: Allow the paint to dry completely according to the manufacturer's instructions.
4. Finishing Touches (Optional)
-
Apply a Clear Coat: For added protection and durability, you can apply a clear coat sealer after the paint has completely dried. Choose a clear coat that is compatible with acrylic paint.
-
Reassemble the Frame: Once the clear coat (if used) is completely dry, reassemble the picture frame.
Materials You'll Need:
| Material | Purpose |
|---|---|
| Soap and Water | Cleaning the frame |
| Fine-Grit Sandpaper | Creating a textured surface for better primer adhesion |
| Tack Cloth/Damp Cloth | Removing sanding dust |
| Plastic-Specific Primer | Creating a bonding layer between the plastic and the paint |
| Acrylic Paint/Spray Paint | Providing the desired color and finish |
| Clear Coat Sealer (Optional) | Adding extra protection and durability |
By following these steps, you can achieve a professional-looking painted finish on your plastic picture frames.
