Frequently Asked Questions – LP® SmartSide® Siding, Trim, and Soffit
1. Can soffit be used for siding?
a. No. The soffit is designed specifically for a protected soffit application
whereas siding is designed for a direct exposure to the weather. Refer to
the installation instructions.
2. Is the LP SmartSide architectural series cedar shake siding primed?
a. Yes. It is primed on the face and edges.
3. Can I install SmartSide over foam sheathing?
a. Yes. The fastener length must provide 1.5-inches of penetration into the
wood stud or combined wood sheathing and stud. Avoid compression of
the foam sheathing. Refer to the foam sheathing manufacturer’s
installation instructions, the LP SmartSide installation instructions, and
the LP SmartSide code reports. LP SmartSide precision series panel siding
provides wall bracing when installed over wall assembly with maximum
1-inch thick foam sheathing on unconditioned side and ½-inch gypsum on
the conditioned side
4. Can I use a traditional transparent or semi-transparent stain on SmartSide products?
a. No. These stains are typically low in solids and provide less protection
from UV and other weathering effects. There are new acrylic latex paints
commercially available that can replicate the appearance of a semi-
transparent stain. Refer to the installation instructions for proper
finishing.
5. Can I use a solid stain on SmartSide products?
a. Yes. These stains are generally lower in solids so increased maintenance
will probably be required. Refer to the installation instructions for proper
finishing.
6. Can I leave Knotty Barnside project panel natural or unpainted?
a. No. It must be primed and painted. Refer to the installation instructions
for proper finishing.
7. Can I use a transparent or semi-transparent stain on Knotty Barnside?

8. Can I install SmartSide trim over lap siding, rather than butting to it?
a. Yes. Special precautions should be taken to provide proper spacing
between the lap siding and the trim, as well as fastening of the trim.

a. No. LP SmartSide panel siding is designed specifically to be installed
parallel to the framing. Refer to the LP SmartSide® Precision series panel
siding installation instructions.
