What is the best paint to use on polyethylene? Paint/Materials
The best paint to use for coating polyethylene is an exterior latex house paint or an elastomeric paint that maintains its flexibility even when dry. This will allow the tank to expand and contract without chipping or tearing the paint.
Does acrylic paint stick to polyethylene? No, not unless the plastic has been prepared by sanding it first, then spraying on a primer. Because plastic is smooth and non-porous, and acrylic paint has a similar consistency when dry, the paint cannot adhere to the plastic.
Can I paint polypropylene plastic? You can apply paint over Polyethylene, Polypropylene, ABS, and PET/PBT Blends with proper surface preparation and primer.
What paint can I use on polypropylene plastic? Because it is often quite smooth and nonporous, most paints have trouble sticking to it. For best results, use a spray paint labeled for use on polypropylene and other plastics. These are available from most major spray paint manufacturers as well as online or at many paint or home improvement centers.
