How Do You Get Paint To Stick to Plastic?
Whether you are painting plastic furniture or something else, the steps for painting a plastic surface are all the same.
Here, you can find out the preparation steps and how to get your paint to stick to the plastic surface.
Choose Paint Materials
Not all paints work on plastic. You require a plastic-specific substance, usually spray paint. A plastic primer will also assist create a flat surface for the paint.
Prepping Plastic Surfaces
To avoid bumps, bubbles, and peeling, start with a clean plastic surface—Prep plastic by removing dirt with mild dish soap and water, and a sponge.
After scrubbing, rinse the plastic to remove any residual soap. Let it dry completely before continuing.
The next step is to roughen the surface to help the paint adhere. To avoid permanent damage to the plastic, lightly sand the surface with a fine-grit sandpaper.
Concentrate on glossy areas, which are often the smoothest and may take the longest to paint. Rinse or wipe the plastic product again to remove sanding dust.
Here, painter’s tape is used to form the line. Protect the surface from primer and paint using a drop cloth. Before applying primer or paint, make sure the area is sufficiently ventilated.
Priming may not be necessary if the paint you buy for painting plastic functions without it, but it never hurts. If you’re using regular spray paint, you’ll need a plastic primer. The specialty primer can lay a basis for paint adhesion.
Apply thin layers of spray primer on sanded, clean, dry plastic. Keep the can moving and at the same distance from the item. Allow the primer to dry completely before painting.
Make sure you shake the can as instructed, and do a test spray to the side and see the jet is as it should be.
When using spray paint, aim it towards the plastic surface from 12 to 18 inches away. To get uniform coverage, keep the nozzle at the same distance from the item. A smooth motion is preferable for painting plastic, overlapping the paint to get a uniform coating.
You’ll likely need many coats of spray paint to cover completely. Rather than one heavy layer that may finish up uneven or drippy, make several thin layers. Always let the paint completely dry between coats.
Spray painting is superior to brush painting because it leaves no brush marks. Likewise, don’t opt for general-purpose spray paints as these are not designed for use on plastic. Use paint designed for plastic; spray paint labeled multi-surface is suitable.
Seal the Plastic Paint
A transparent acrylic sealant protects your freshly painted plastic surface. Sealer is optional, although it can help the effects last longer, especially if painting an outdoor item. A spray sealer makes the job easier.
Apply sealant when the paint has dried. Spray it on like paint, with even, smooth, overlapping sprays. One application of sealer is usually sufficient, although extreme conditions may need more. (Learn How To Get Sticky Residue Off Plastic)
With the correct paint and preparation, you can paint your favorite plastic things smoothly.
Guide for Painting with Acrylics
Acrylic paint dries on plastic, making it impossible to stick paint on plastic. Under the right conditions, you can make an acrylic paint stick.
Often, craft acrylic paints aren’t supposed to stick to plastic, so they peel away.
Larger surfaces benefit from acrylic plastic spray paint you can apply in several light coats. Bottled and tubed craft paint won’t stick as well.
If you’re painting smaller objects or adding fine details to plastic, bottled acrylics are easier to use with a paintbrush. This paint is also fantastic for recycled plastic bottles and jars.
Some acrylic paints contain priming or sealer. This type of spray paint for plastic is common. To get the greatest results, some require surface prep and paint sealing.
Some craft acrylic paint in bottles won’t stick to polyethylene and polypropylene. The bottom recycling logo shows the plastic kind.
Other polymers require priming and sealing. You can also use a methylated primer/sealer on tough surfaces.
Make Acrylic Paint Stick to Plastic
To keep acrylic paint on plastic, you must first prepare it, clean, sand, and prime it. After painting, seal the surface to provide a waterproofing layer and extend the paint’s lifespan.
Contamination is the primary cause of acrylic paint peeling off plastic, starting with mild dish soap and warm water. You can use a cleanser or degreaser designed to remove grease or dirt. Sanding plastic is a great way to help the paint bond thoroughly, and then you can brush or spray primer onto plastic in thin coats, so it sticks.
How to Paint Plastic With Acrylic Paint
Painting plastic with bottled acrylic paint differs from painting with spray paint. Use the steps below to apply paint from a bottle or tube. Keep in mind that the materials required will depend on the color used. (Read Remove Spray Paint From Plastic)
Make sure you have protective gear and clothing that you don’t mind getting paint on. Put down a drop cloth or newspaper.
Open a window or move to a well-ventilated area.
- 180-220 Fine-grit sandpaper
- Painter’s tape
- Craft paint (made for plastic)
- Dish soap
- Rubbing alcohol
Prepping Plastic for Paint
- Clean the plastic surface using mild dish soap and warm water.
- Rinse with clean water then dry with a soft towel.
- Cover the surface with rubbing alcohol or mineral spirits, and leave to dry. The rubbing alcohol removes grease, oil, and fingerprints.
- Grab your fine-grit sandpaper, and lightly rub shiny surfaces. Because plastic is a nonporous surface, removing shiny ares increases paint adhesion.
- After sanding, wipe with a clean towel to remove dust.
Add Plastic Primer
- Primer aids in the adhesion of paint. For the greatest results, use a primer made for plastic. Many kinds are available as spray primer, although liquid solutions in cans or bottles are also available for models and other purposes.
- Follow the instructions on the bottle to apply the primer. Apply small layers of paint to the entire surface.
- Allow for complete drying of the primer.
Mark off the parts you don’t want to paint with painter’s tape before you start painting.
To apply the paint, use a paintbrush or a sponge. If you add acrylics too thickly, the layer may not adhere well.
Finally, allow at least two hours for your item to dry. Some craft paints might take anything from six to twelve hours to completely dry.
Spray Paint on Plastic
Before spray painting plastic, clean, sand, and prime it as you would with acrylic paint. Prep the plastic as described above.
Read the paint’s label. Some spray paints require shaking before and during use. The label will also tell you if you need to use primer and sealer.
If you use standard spray paint (not plastic-specific regular spray paint), you must prep the surface. You can use plastic priming sprays. For optimum results, follow the bottle’s directions. Never paint over primed surfaces.
Test the spray paint on newspaper, cardboard, or your drop cloth. Verify the paint color and uniformity.
Apply a thin, light coat of spray paint onto the object. Keep the spray can 8-12 inches from the surface. You won’t have complete coverage of the first coat, and if you apply the first layer too fast and too thick, drips will appear. To remove dried drips, sand the surface level before applying the next layer.
Once dried, add another layer. You’ll probably need several thin applications of paint. Mist the plastic lightly from 12 inches away.
If the surface is still not entirely covered and saturated after two hours, carefully apply a third layer to the plastic.
Allow the spray paint to dry completely before using it. Keep the thing warm and dry for two hours.
Seal Acrylic Paint on Plastic
Plastic goods are frequently handled, so the paint needs to be sealed. The sealer also protects water-based acrylic paints from rain and dampness.
Sealants are liquid or sprayed. Many spray sealers come in glossy or matte finishes. Spray sealers are said to be easier and offer a smooth surface. Regardless, the sealer should work with acrylic paints and create a protective surface.
On thoroughly dried paint, apply a sealant to the final coat of paint carefully. Use the same approach as painting to apply a spray sealer for a flawless finish. Brush-on liquid sealers often require two coatings, but spray sealers require one.
Outdoor things may require an extra layer. Items often exposed to hostile circumstances will require extra protection from the final coat.
Tips for Painting Plastic with Acrylic Paint
Here are a couple of tips you may need for painting plastic with acrylics.
