Is it safe to paint vinyl?

Until now, there were limitations to painting vinyl. Using a dark color on top of a lighter would cause the substrate to buckle. Your only option was to choose the same color or lighter. No longer.

Sherwin-Williams VinylSafe® paint colors allow you the freedom to choose from 100 color options, including a limited selection of darker colors formulated to resist warping or buckling when applied to a sound, stable vinyl substrate.
