You can use a spray-on outdoor paint or a brush on paint. To use a spray-on paint, leave the surface of the EVA plastic to be painted free from dust or debris. Next, if you are using a high gloss spray-on paint, you need to apply two coats of the gloss paint. If you are using a high-gloss latex paint, you just need to apply one coat. If you are using a low gloss paint, apply two coats. For more information search Google.
