Painting plastic ornaments can be a fun DIY project, but it can be frustrating when the paint doesn't stick. To get paint to adhere to plastic ornaments, several methods can be used, including using a primer or sealer, applying hairspray or rubbing alcohol before painting, and allowing each layer of paint to dry completely before adding the next. Some people also suggest using multiple thin coats of paint instead of fewer thicker coats and ensuring that the ornaments are well-ventilated during the drying process. Additionally, it's important to avoid heat sources or direct sunlight, as they can cause the paint to melt or become streaky.

What You'll Learn
Using hairspray as an adhesive base
Painting plastic ornaments can be a fun DIY project, but getting the paint to stick to the plastic can be challenging. One creative solution is to use hairspray as an adhesive base. This method can be particularly useful if you plan to use acrylic paint, which can sometimes be tricky to work with on plastic surfaces.
To begin, it's important to prepare your work area and have all the necessary supplies ready. Gather your plastic ornaments, hairspray, paintbrushes, and paint colors of your choice. It's also a good idea to lay down some newspaper or a drop cloth to protect your work surface from any potential spills. Ensure the plastic ornaments are clean and dry before starting the painting process.
Now, for the hairspray application. Hold the hairspray can about 6-8 inches away from the ornament and spray a light, even coat onto the plastic surface. You don't want to apply too much hairspray, as it may cause dripping or pooling. Allow the hairspray to dry completely before moving on to the next step. Depending on the brand of hairspray and the humidity in your workspace, this could take anywhere from a few minutes to an hour.
Once the hairspray is dry, you can start painting your ornament. Using a small paintbrush, apply your chosen paint color in thin, even coats. It's generally best to let each layer of paint dry completely before adding subsequent coats to avoid smudging or streaking. Depending on the paint you're using, you may need to apply multiple coats to achieve the desired opacity and color saturation.

Applying a rubbing alcohol rinse
If you're looking to get paint to stick to plastic ornaments, one method you can try is applying a rubbing alcohol rinse. Rubbing alcohol, or isopropyl alcohol, is a common and versatile household item with many uses, including cleaning, disinfecting, and polishing.
To apply a rubbing alcohol rinse to your plastic ornaments, start by pouring some rubbing alcohol into the ornament. Cover the hole and shake well to ensure that the alcohol coats all the surfaces inside. Then, pour out the excess alcohol into a sink or container. It is important to ensure that all the surfaces are coated, as this will help the paint adhere better and create a more even finish.
Let the ornament dry completely before applying paint. This step is crucial, as any remaining alcohol could affect the paint's ability to stick to the plastic. Depending on your environment, the drying time may vary, so it is best to leave it overnight to ensure that all the alcohol has evaporated.
Once the ornament is dry, you can start painting. You can use various types of paint, such as enamel or acrylic. It is important to follow the specific instructions for the type of paint you are using, such as the recommended number of coats and drying time between coats.
After you have finished painting your ornament, let it dry completely before handling it or adding any additional decorations. This will help ensure that your paint job remains intact and that your ornament is ready for display.

Using a primer
Painting plastic ornaments can be challenging as the paint tends to drip, pool, and blotch, and once dried, it can quickly peel off. To get paint to stick to plastic, you need to prepare the surface properly and use the right products. Here is a step-by-step guide on how to use a primer to get paint to stick to plastic ornaments:
Step 1: Sand the Plastic Ornament
Use fine-grit sandpaper to rough up the surface of the plastic ornament. Most plastic surfaces are smooth, so sanding will create a rougher surface for the paint to adhere to. Be sure to sand in one direction to avoid visible sanding marks, and use a light touch to avoid damaging the plastic.
Step 2: Remove Sanding Dust
Once you have finished sanding, use a dry cloth to wipe away the bulk of the sanding dust. Then, use a wet rag with mineral spirits or isopropyl alcohol to remove any remaining particles. It is important to remove all the dust so that there is no barrier between the primer and the plastic ornament.
Step 3: Prepare your Work Area
Set up a protected work area to avoid getting spray paint on unwanted surfaces. It is recommended to work on a flat surface, such as old cardboard, as paint tends to smear on sheet plastic. Be sure to work in a well-ventilated space, avoid heat sources, and do not eat or drink in the area.
Step 4: Apply the Primer
Lay the plastic ornament flat on your work surface. If using an aerosol primer, hold the nozzle 10-14 inches from the surface and spray in steady, even, overlapping strokes. Apply light and even coats, working in one direction without going back over areas you have already sprayed. A single coat is usually enough, but you can add additional coats if needed, allowing proper drying time between each coat.
Step 5: Allow the Primer to Dry
Follow the manufacturer's instructions for drying time. For example, Fusion SEP requires a one-hour dry time before sanding, priming, or top-coating. It is important to wait the recommended amount of time to ensure the primer is fully cured and will provide a strong bond for the paint.
By following these steps and using a primer specifically designed for plastic, you can create a strong and flexible base coat that will help the paint stick to your plastic ornaments and prevent peeling and cracking.

Painting the outside of the ornament
Painting the outside of a plastic ornament is a simple process, but it requires some preparation to ensure the paint adheres properly and doesn't streak or pool. Firstly, it is important to clean the ornament with a substance like rubbing alcohol, which will ensure the surface is ready for painting. This will also help the paint adhere better. Allow the ornament to dry completely before painting.
Next, choose a suitable paint. Multi-surface acrylic craft paint is a good option, and it is available in many colours. It is important to apply thin coats of paint, rather than one thick coat. Allow each coat to dry completely before adding another. This is crucial, as applying paint too thickly or before the previous layer has dried can cause streaking and pooling. If you are using a cheaper paint, be aware that it may be more prone to streaking and may need more coats.
Once you have applied your final coat of paint, you can add a thick, even layer of mod podge to seal the paint and add extra protection. If you are painting multiple ornaments, it is important to seal each one individually, so the glue doesn't dry out.

Using a flocking method
Flocking is a process that involves depositing tiny fibres onto a surface to create a smooth, matte texture. This can be achieved by using a spray adhesive or glue to bond the fibres to the plastic surface of the ornament. Here is a step-by-step guide to using the flocking method to get paint to stick to plastic ornaments:
Step 1: Prepare the Ornament
Before applying any paint or adhesive, ensure that the plastic ornament is clean and dry. It may be helpful to place the ornament on a stick to make it easier to hold and rotate during the painting and flocking process.
Step 2: Paint the Base
It is recommended to paint the base of the ornament with a colour that matches your flocking powder. This helps to ensure that any thin areas of flocking powder are less noticeable. You can squeeze a small amount of paint inside the ornament and then twirl it around until it coats the entire inside.
Step 3: Apply the Spray Adhesive
Once the base paint is dry, you can apply the spray adhesive. Place the ornament in a box to prevent overspray and wear gloves to protect your hands. Spray the adhesive evenly over the surface of the ornament, following the instructions on the product to ensure it remains tacky for the appropriate amount of time.
Step 4: Apply the Flocking Powder
Shake a small amount of flocking powder over the ornament, gently turning it to ensure an even coat. You can use a mini strainer or flour sifter to help distribute the powder evenly and prevent clumping. Ensure the entire surface of the ornament is covered.
Step 5: Remove Excess Powder
Once the adhesive is dry, use a chopstick to spin the ornament and remove any excess flocking powder. You can also flick your wrist while holding the chopstick to shake off any extra powder.
Step 6: Finish and Display
After removing the excess powder, you can insert the ornament cap and tie a ribbon to hang it on your tree. Your ornament is now ready to be displayed, with a unique, velvety look and feel!
