Sanding plastic before painting improves adhesion
Painting plastic is similar to painting other types of materials, but there are some special procedures and precautions to be aware of. For instance, plastic parts are often contaminated with mould release agents, which are lubricants injected with the plastic media during manufacturing. These agents must be removed before painting, as they cover the entire surface of the part, inside and out.
To ensure paint adheres to plastic, it is recommended to sand the surface first. Sanding gives the plastic a little more texture, improving the paint's ability to stick. Fine-grit sandpaper should be used to wet sand the plastic, as this will not scratch it. It is also advisable to use a sanding sponge or foam block, as this will give you better control and prevent the sandpaper from cutting too deeply into the plastic. To avoid harsh lines, move the sponge in a circular motion.
After sanding, the surface should be cleaned with a damp cloth. Once the plastic has been prepared, an adhesion promoter should be applied before refinishing to ensure the finish does not delaminate later. The type of adhesion promoter will depend on the type of plastic being painted. For example, if the plastic is HDPE, a special primer is needed.
After the adhesion promoter, the next step is to apply a primer. Once the primer has been applied, the plastic can be painted.

Waterproof sealers can be applied after painting
Painting plastic can be challenging since it is not a porous material, making it difficult for the paint to stick. With the right preparation, however, you can achieve success in painting plastic items.
To begin, it is important to clean the plastic surface with mild dish soap and warm water to remove any dirt or residue. You can use a soft cloth or sponge for smooth surfaces and a scrubbing brush for textured surfaces. Once the surface is clean, dry it off completely. The next step is to sand the surface lightly with fine-grit sandpaper. This process helps to create a rough texture, allowing the paint to adhere better. Focus on the shiny areas, as they are often the smoothest and may have difficulty accepting paint. After sanding, wipe off the dust with a damp cloth or hose off the plastic to ensure no residue is left behind.
Before painting, it is recommended to apply a coat of primer specifically designed for plastic surfaces. The primer will help create a smooth foundation for the paint to adhere to. Once the primer is dry, you can apply the paint. It is important to use a paint product specifically designed for plastic, which is often in the form of spray paint.
To make your painted plastic surface waterproof, you can apply a clear acrylic sealer. The sealer will provide an extra layer of protection and help make the results more permanent, especially for outdoor items. You can find spray sealers that are easy to apply, ensuring consistent, smooth, and overlapping sprays. Typically, one coat of sealer is sufficient, but if the item is exposed to harsh conditions, you may consider applying additional coats. Allow each layer to dry before applying the next.
By following these steps and allowing adequate time for preparation and drying, you can achieve a smooth, waterproof finish on your painted plastic items.
