Dust collecting on Summit XPS board

• Boards must be cleaned/wiped down with a solution of fabric softener or dishwashing liquid in water, to remove the static electricity buildup that causes dust particles to settle.

• Avoid butt joints.
• Always secure boards along the tongue-and-groove ends to prevent movement.
• Increase substructure spacing when installing Summit XPS board in areas that are exposed to wind.
• If painting Summit XPS board, use only water-based paint. The use of any solvents will damage the Summit XPS board.
