Can I paint HDPE sheet?

HDPE sheet is produced with a closed cell structure polymer. This means it will not absorb liquids, but also means that paint or stain will not adhere to it. The best way to obtain a colored sheet is to have it produced that way!  iPoly stocks many colors and can also produce custom colors. The color and pigmentation process for HDPE sheet ensures the color is through the entire sheet, and therefore is better than a surface coating, which could scratch or flake off.
