To Paint FlexFoam-iT! Flexible Foam: If you attempt to paint a flexible foam with a standard latex or acrylic paint, the painted surface could crack when the flexible foam part is flexed. You need a paint that will bend and flex with the flexible foam. UreCoat™ is easily colored with SO-Strong™, UVO™ or Ignite™ colorants to create a permanent paint for coating cured Smooth-On urethane rubbers or flexible foams. In addition, some customers have used our Brush-On 40 urethane rubber thinned with a small amount of mineral spirits as a paint. It is easily color pigmented with SO-Strong color tints. You can also paint the cured surface of flexible foam with fabric paint or flexible acrylic enamel paints. You must make sure the paint adheres to the foam and is flexible after it dries.
