Is FROTH-PAK suitable for outdoor use?
Polyurethane foams are very sensitive to UV light. Exposure to UV (even indirect sunlight) will cause the foam to darken to an orange or reddish color in a matter of days or weeks. Constant exposure to direct sunlight will eventually cause the foam to break down and crumble apart. The foam must be painted or coated with UV resistant coating if used outdoors. FROTH-PAK may be used to fill cavities in trees. As with all outside applications, the foam should be coated to protect it from UV and water exposure.
