19. Can LP® SmartSide® trim and fascia be miter cut?
a. Do not miter cut the edges or ends of the trim at corners. Miter cuts or
“picture framing” around door and window openings are acceptable. Butt
joints are preferred but scarfed joints are permitted with LP SmartSide

expansion during equilibration. Refer to the installation instructions for
proper installation.
20. Can I overlap my LP SmartSide siding more than the recommended 1”?

The specified overlap and edge-spacing of the nails in the installation
instructions are minimum requirements. Refer to the installation
instructions for proper installation.

the material safety data sheet (MSDS) before using the product indoors.
