How to Seal Acrylic Paint on Plastic

There are several ways that you can seal acrylic paint on plastic. One popular method is to use a clear acrylic sealer. This will provide a durable and long-lasting finish. You can also use an acrylic varnish, which comes in both aerosol forms like sprays and in brush-on bottles.

Does Acrylic Paint Stick to Plastic?

Yes! Acrylic paint adheres well to most plastics, including polyurethane, polypropylene, and polystyrene.

In fact, acrylic paint is often used on plastic models and figurines. When painting on plastic, choosing the right type of paint is important.

Some plastics are more porous than others, so you’ll need to use an acrylic primer to help the paint adhere.

You should also look for paints that are specifically designed for use on plastic. These paints usually have better coverage and adhesion than regular acrylic paints.

Should I Seal My Acrylic Painting?

The short answer is that you don’t have to seal your acrylic painting, but there are some advantages to doing so.

Sealing your painting can help to protect it from dirt, dust, and smudging. It can also make the colors appear more vibrant and prevent the paint from chipping or flaking off.

If you’re planning to hang your painting in a high-traffic area or if it will be exposed to direct sunlight, sealing it can help to prolong its lifespan.

Ultimately, the decision of whether or not to seal your painting is up to you.

How to Prep Plastic for Paint

Before you start painting, it’s important to clean the plastic surface and ensure it’s free of any dirt or debris.

You can use a mild soap and water solution or a commercial plastic cleaner to clean the surface.

Once the surface is clean, you’ll need to sand it down to create a rough surface for the paint to adhere to.

Once you’ve sanded the surface, wipe it down with a damp cloth to remove any dust.

How To Prime Plastic For Acrylic Paint!

You’ll need to apply a primer after cleaning and sanding the plastic surface. This will help the paint to stick better and provide a more even coverage.

You can use any type of primer, but we recommend using an acrylic-based primer.

Apply the primer with a brush or roller and cover the entire surface. Once the freshly painted plastic surface is dry, you’re ready to start painting!

Painting plastic with acrylic paint step by step

Step One: Choose your colors.

When painting on plastic, you can use any type of acrylic paint. However, we recommend using paints that are specifically designed for use on plastic.

These paints usually have better coverage and adhesion than regular acrylic paints.

Step Two: Pour some paint into a cup or bowl.

When painting with acrylics, it’s important to use thin layers of paint. This will help to prevent the paint from cracking or peeling off.

To avoid using too much paint, start by pouring a small amount of paint into a cup or bowl.

Step Three: Load your brush with paint.

Dip your brush into the paint and then tap it on the side of the cup to remove any excess. You should only load your brush with a small amount of paint at a time.

Step Four: Paint in long, even strokes.

Start painting in one corner of the plastic surface and then paint in long, even strokes. Work your way across the surface until you’ve covered the entire area.

Step Five: Let the paint dry.

Acrylic paint dries quickly, so you won’t have to wait long for it to dry. Once it’s dry, you can add additional layers of paint if necessary.

That’s it! You’ve now learned how to paint plastic with acrylic paint. Remember to use thin layers of paint and to let each layer dry before adding another.

Here’s a step-by-step guide to sealing your painting

Step One: Choose an acrylic sealer.

Just like choosing the right paint for plastic, it is important to choose an acrylic sealer. This type of sealer will help to protect your painting and make it last longer.

We recommend using aerosol spray sealant because it’s easy to apply and provides a great seal.

Step Two: Pour the sealer into a cup or bowl.

Pour a small amount of sealer into a cup or bowl. You don’t need to use a lot, just enough to cover the surface of your painting.

Step Three: Load your brush with sealer.

Dip your brush into the sealer and then tap it on the side of the cup to remove any excess. You should only load your brush with a small amount of sealer at a time.

Step Four: Apply the sealer in thin layers.

Start by applying a thin layer of sealer to your painting. Use even strokes and make sure that you don’t miss any spots.

Once you’ve applied the first layer, let it dry for about 15 minutes. Remember to hold the canister around 30cm away from the surface.

Step Five: Apply additional layers of sealer.

After the first layer has dried, you can apply additional layers if necessary. However, we recommend applying two or three layers for best results.

Let each layer dry for 15 minutes before adding the next one.
