How to apply a sealant for acrylic paint on plastic
To seal acrylic paint on plastic at home, you can follow these steps:
- Clean the plastic surface: Before you start painting, make sure the plastic surface is clean and dry. You can use soap and water to clean it, or a rubbing alcohol solution if the plastic is particularly greasy or dirty.
- Apply the acrylic paint: Once the plastic surface is clean and dry, apply the acrylic paint using a brush or sponge. Allow the paint to dry completely before proceeding.
- Apply a sealing coat: Once the acrylic paint is dry, apply a sealing coat over it to protect the paint and prevent it from peeling or chipping. You can use a clear acrylic sealer, which can be found at most hardware stores or online. Spray the sealer evenly over the surface of the painted plastic, holding the can about 8-10 inches away. Allow the sealer to dry completely.
- Apply a second coat: Depending on the sealer you’re using, you may need to apply a second coat to ensure complete coverage. Follow the manufacturer’s instructions for the specific sealer you’re using.
- Let it cure: After the final coat of sealer has dried, allow the painted plastic to cure for at least 24 hours before handling or using it.
Following these steps will help you seal acrylic paint on plastic at home and create a long-lasting finish.

Sealing acrylic paint on plastic models
When working with plastic models, it’s important to use an acrylic paint that is formulated to adhere to plastic surfaces. Once you have painted your plastic model with acrylic paint, it’s a good idea to seal the paint to protect it from damage and preserve its appearance over time.

- Allow each coat to dry completely before applying the next one. Check the instructions on your sealant to see how long it takes to dry.
- Apply at least two coats of sealant to ensure that the paint is completely protected. You can apply additional coats if desired.
