What You'll Learn
Using hairspray as a primer
Sealing paint on a plastic ornament can be done in several ways, and one of them is by using hairspray as a primer. This technique is a unique process used to create chipping effects on the surface of a model. It involves using aerosol hairspray to release an underlying coat of paint.
To use the hairspray technique effectively, start by choosing the right primer colour, as this will be the shade that the hairspray technique exposes. Primer is a type of paint that prepares the surface of the plastic ornament for subsequent coats of paint. It makes it easier for the paint to adhere to the ornament and is more resilient than the additional coats. It is good practice to let the primer dry for 24 hours before proceeding.
After applying the primer, you can then use acrylic paint on top. Once the acrylic paint is dry, wet it with tap water applied with a brush or a light coating applied via an airbrush. The water will activate the paint and make it easier to remove. You can then selectively remove the paint using tools like a toothbrush, a firm-bristled brush, or a toothpick. The hairspray will protect the underlying primer by providing a degree of waterproofing, allowing the acrylic topcoat to sit on it with weaker adhesion.
The hairspray technique is a creative way to add unique effects to your painted plastic ornament. It offers a different approach to traditional painting methods and can be a fun way to customize your ornaments. This technique is also useful if you want to create a distressed or vintage look for your ornament.

Applying a water-based clear coat
Sealing paint on a plastic ornament is a great way to add extra durability and longevity to your decorations. One way to do this is by using a water-based clear coat. Here is a step-by-step guide on how to apply a water-based clear coat to your plastic ornament:
Prepare the Ornament:
Start by removing any caps or hangers from the ornament. If you are painting the ornament, ensure it is thoroughly cleaned and dried before beginning the sealing process. You may want to use chopsticks or skewers to hold the ornament while painting, as this will help you avoid getting paint or sealant on your fingers. Tape the chopstick to the ornament securely, so it doesn't move around.
Choose the Right Water-Based Clear Coat:
Select a water-based clear coat designed for use with plastic ornaments. You can typically find these at craft stores or home improvement retailers. Avoid using lacquer or eurothane clear coats, as they may interact with the paint and turn it yellow.
Apply the Clear Coat:
Follow the instructions on the water-based clear coat spray can. Hold the can about 6-8 inches away from the ornament and spray using light, even strokes. Ensure you are in a well-ventilated area or working outdoors. Apply a thin, light coat first and allow it to dry for about 15 minutes. You can then apply a second coat for added protection.
Drying and Finishing:
Allow the final coat of the water-based clear coat to dry completely. This may take a few hours or up to 24-48 hours, depending on the product and environmental conditions. Once the ornament is dry to the touch, you can reattach the cap or hanger and add any ribbons or embellishments. Your ornament is now sealed and protected!
Tips:
If you are using a glitter blast ornament, you may want to use a clear sealer specifically designed for glitter to prevent glitter from falling off and ensure it doesn't end up all over your house!

Using mod podge
Mod Podge is a popular product for sealing paint on plastic ornaments. It is a type of glue, sealer, and finish all in one. It is available in various finishes, including matte, gloss, and satin, and you can choose the one that complements your project. For example, if you want a shiny, glass-like finish, go for gloss Mod Podge; if you prefer a more subtle look, choose the matte or satin finish. Mod Podge is also available in different formulas, such as the original formula and the hard coat formula, each providing a different finish.
Before applying Mod Podge, it is important to clean the plastic surface with soap and water. You'll also need to test the surface because Mod Podge doesn't stick to all plastics. Once the surface is prepared, apply the Mod Podge over the paint using a soft brush to avoid brush strokes. Apply thin, even layers, allowing each layer to dry completely before applying the next. Typically, 2-3 coats are sufficient for most projects.
It is important to note that Mod Podge requires a significant amount of time to cure fully. While it might feel dry to the touch within an hour, it is advisable to let it cure for at least 28 days, especially if you are using the dishwasher-safe version. This extended curing time ensures maximum durability and water resistance.
If you find that your Mod Podged item is still tacky even after the suggested curing time, you can use a clear acrylic spray or brush-on sealer on top. This additional sealer gives your project an extra layer of protection.

Drying ornaments upside down
Prepare the Workspace:
Before you begin, gather the necessary materials: paper towels, a plastic cup (optional), and a flat surface to work on. If using a plastic cup, ensure it is slightly smaller than your ornament. This method will help catch any dripping paint and keep your workspace tidy.
Drain Excess Paint:
Place the ornament upside down on the paper towel. This will allow the extra paint to drain out. Move the ornament to a clean spot on the paper towel every few minutes to absorb the excess paint. Alternatively, if you have a round sphere ornament, place it in the plastic cup, which will catch the dripping paint.
Allow Drying Time:
After draining the excess paint, let the ornament dry completely. This typically takes 24 to 48 hours. During this time, the paint will set, and your ornament will be ready for further customization or display.
Finalize and Display:
Once the ornament is dry, replace the lid and your painted ornament is ready! You can add vinyl or any other final touches before the 24 hours are up, as long as there is no dripping paint. Now, your ornament is ready to hang or gift!

Adding vinyl or glitter
Using Vinyl
To add vinyl to your plastic ornament, start by removing the top of the ornament. If you are using a round sphere ornament, place it in a plastic cup that is slightly smaller so that any excess paint or adhesive can drip into the cup. You can then add paint to the inside of the ornament. Acrylic craft paint is a good option as it is inexpensive and comes in a wide range of colours. After adding paint, wait 24 to 48 hours before proceeding to the next step.
Once the paint is dry, you can add vinyl to your ornament. You can cut out vinyl stickers and place them on top of the painted surface. To ensure that the vinyl sticker is centred, tape the top of the decal using painter's masking tape. Spray floating liquid onto the plastic, remove the backing on the sticker, and smooth out any bubbles with your fingers.
Using Glitter
To add glitter to your plastic ornament, you can use a variety of techniques and products. One option is to use a spray-on glaze sealant, which will help to prevent glitter from shedding. You can also use a sealant that is pour-on or clear spray-on, such as Mod Podge, an epoxy coating, or a spray-on glaze. Mod Podge can be applied to a wide range of surfaces, including plastic, and dries clear. You can mix the glitter directly into the Mod Podge and brush it onto your ornament like paint, allowing it to dry between coats.
Another option is to use an adhesive such as Polycrylic, Glitter-It!, or Mop and Glo. Coat the inside of your ornament with the adhesive and allow it to drain into a plastic cup. Once the excess has drained out, pour a small amount of glitter into your ornament and gently swirl it around to coat the entire surface. Be sure to let your ornament dry for 24 hours before putting the cap back on.
You can also seal glitter onto your ornament using a thin layer of glue or varnish. Varnish can be purchased in the craft paint section and can be used in the same way as floor wax. If using varnish, swirl it around and let most of the excess drain before adding the glitter. Cover the opening with a scrap of paper and shake vigorously to distribute. Allow 24 hours to dry.
If you are looking for a quick and easy option, hairspray can be used to seal glitter onto fabric. Simply spray your item and you're ready to go!
