Even when the plastic looks clean, it could still have residue that affects adhesion. This is why preparation is the most important step when using acrylic spray paint on plastic.
Before painting, wash the plastic item with warm water and delicate dish soap. This removes dirt, grease, and surface contaminants. After washing, rinse it well and let it dry completely. Any moisture left on the surface can intervene with the paint and cause poor results.
Next, lightly sand the plastic with fine-grit sandpaper. You don’t want to sand aggressively. The goal is just to create a slightly rough texture so the paint has something to grip. After sanding, wipe away the dust with a clean cloth. This small step can make a big distinction in how well the acrylic spray paint adheres.

Let it dry according to the product directions earlier than making use of the paint. Skipping primer might work for some small decorative projects, but for long-lasting results, primer is often the safer choice.
