Can Precision Board Plus be used outside in all exterior environments?
Yes it can. Precision Board Plus, being a closed cell product, absorbs no moisture. It is a fairly good insulator so temperature does not migrate into it. It has been tested from -423°F to +300°F with no degradation or breakdown. It doesn’t absorb water from high humidity, rain, snow, or ice so it does not expand or contract because of water intrusion. This means it doesn’t warp or crack and the paint lasts longer and stays brighter than on wood.
