WISA-SpruceWR is a lightweight water repellent plywood panel for structural uses. The wood-based water repellent coating agent protects the panel from the weather and adds efficiency to construction work. The wood-based agent creates a barrier slowing the rate of moisture penetration to the structure. At the same time, the surface allows the panel to breath and dry freely.
