Spray painting plastic – how to spray paint plastic

Spray painting plastic can be a quick and effective way to refresh or transform various objects, from garden furniture to decorative items. However, plastic surfaces require special treatment before painting to ensure the paint adheres well and the finish lasts. Here’s a short guide to help you achieve the best results.

Easy instructions on how to spray paint plastic

1. Preparation

Set up a well-ventilated area and protect it with newspapers or a drop cloth from overspray. Clean the plastic object thoroughly by removing any dirt and grime. For improved adhesion, especially on high-gloss slippery plastic surfaces, scuff lightly with 180 grit abrasive paper. Finalise by removing any grease with Maston Degreaser and let dry completely before application. 

2. Priming

Test painting on a non-visible surface before application. First, apply Maston Plastic Primer to create a good adhesion. Spray in an even, thin coat and let it dry as instructed in the can.

Maston Plastic Primer is a transparent specialty coating, which ensures superior adhesion and longevity for plastic objects before painting.

3. Painting

Apply a high quality acrylic paint – we recommend Maston ONE spray paint, which dries quickly and offers superior UV-resistance for applications indoor and outdoor. Paint in steady back-and-forth motions to apply multiple thin layers, allowing each to dry before the next. This method prevents drips and ensures a smooth finish.

4. Optional: Finishing

Once the final coat is dry, consider a clear coat to seal the paintjob for added durability, especially for outdoor items. Maston ONE Clear Coat is recommended.

This simple process enhances the item’s appearance and extends its lifespan, perfect for any DIY project.
