Regarding this, what kind of paint will stick to plastic ornaments?Spray plastic with hairspray (I’ve used White Rain) first and let dry then paint on the acrylic paint. I’ve used this technique a couple of times and it seems to work well! The hairspray sticks to the plastic and the paint sticks to the hairspray.Furthermore, how do you get acrylic paint to stick to plastic? Spray paint works especially well for plastic, but you can use acrylic or enamel/model paint as well. Apply a light, even coat of paint. Hold spray cans 12 to 18 inches (30 to 46 centimeters) away from the surface. Apply acrylic paints using a taklon, kanekalon, or sable brush. Also question is, what to fill clear ornaments with? Fill the ornaments with sand and shells or sea glass and embrace the place. Filling ornaments with glitter, pompoms, confetti, stars made of book pages are very popular ideas. Create a mini terrarium with faux snow and tiny trees, or origami pieces.Does acrylic paint stay on plastic?Acrylic paint can be used on plastic, but it is not specifically designed for this use. Acrylics don’t always hold up as well to repeated handling as other paints, and they work better on surfaces that allow air through, like wood and paper, than they do on plastic.
