Plastic has revolutionized the world, and thankfully, painting plastic has never been easier with the use of cheap spray paint. But if you want that finish to be durable and good looking, you should take some form of preparation so that the paint looks as best as possible.
Choosing a Paint
This may seem like the easiest part, but one thing you need to look out for is to make sure that your paint allows you to paint on plastic. Most spray paints you buy from a hardware store should be all good. The other thing you need to check for is if the spray paint needs a primer. Lastly, before you leave the store decide if you want to buy any paint sealer to give your paint an extra layer of protection. Now you’re ready to paint… well almost.
The first step is to clean the surface, don’t use any strong solvents like acetone or brake cleaner as plastic usually dissolves in solvents like this. Rather just use good old dish soap and elbow grease to get much of the dirt off. Now take high grit sandpaper and rub it gently across the surface just to create a surface that is more acceptable to paint. Don’t cause any gouges or dents in the plastic as this will ruin the piece and you will have to start over.
If you have a separate primer, then apply it evenly across the whole piece, remembering to stay an even distance at all times to prevent pooling or splotches that will have to be reworked. Now next is the part where you use the same techniques to apply it as the primer. And if your spray paint doesn’t need a primer, then you can just start spraying. Keep the same techniques in mind when painting though. You will need multiple coats and maybe even multiple cans depending on how big the piece is. Remember to let the paint dry before starting a new coat. Once you are done let the paint dry completely. If you decide to put a sealer on then spray it on the same way you did with the paint. This time you only need one coat. And boom, you’re DONE!
