Water Run-O Control
• Properly installed ashing materials will help direct water away from
common water collecting areas.
• All ashing material shall be metal or another durable material that
under normal outdoor environmental conditions will last for a period
of not less than 50 years.
• All ashing materials must have a minimum 4 inch upper leg. Add a 4
inch wide adhesive ashing to ashing legs less than
4 inches.
• Properly integrate ashing with the secondary WRB. Use housewrap,
ashing tape, kickout ashing, step ashing,
Z-ashing, drip edge, gutters or other items as needed to maintain the
counter-ashing principle.
• Install kickout ashing to direct the water into the gutter. (Diagram 2a)
• Install step ashing that has a minimum 4 inch upper leg. (Diagram 2a)
• Maintain a minimum 1 inch clearance between the end of the gutter
and the adjoining wall to allow for proper maintenance of the siding.
(Diagram 2b)
• Do not extend the siding or trim into the kickout ashing or gutter.
• Prime and paint ALL exposed cut edges of siding.
• Moisture control and moisture vapor control are critical elements of proper housing design and construction. Check your
local building codes for application procedures for handling moisture and water vapor in your area.
• Follow all applicable building code specications relating to prevention of moisture intrusion into the wall assembly. LP®
SmartSide® siding is a wood product, and, as with all wood products, must be kept free from excessive moisture. Lack of
proper ventilation; exposure to constant or repetitive sources of water such as sprinklers, condensation, inadequate ashing;
improper sealing; or failure to follow common building practices that prevent moisture intrusion into the wall system may
cause damage, and products subject to such treatment will be excluded from warranty coverage.
• As with all wood products, do not apply engineered wood siding to a structure having excessive moisture conditions such as
drying concrete, plaster, or wet blown cellulose insulation. If such conditions exist, the building should be well ventilated to
allow it to dry prior to the application of the siding.
• Gutters with kick-out ashing and eave drip edge are recommended for control of roof water run o.
Moisture Control
• A properly installed breathable water-resistive barrier is required behind the siding. Consult your local building code for
details.
• LP will assume no responsibility for water penetration, or damage it may cause.

• Trim should be thick enough so the siding does not extend beyond the face of the trim.
• Trim and fascia must be applied in a manner that will not allow moisture intrusion or water buildup.
Trim
• All openings must be properly sealed or ashed in a manner that prevents moisture intrusion or buildup. Several examples
that accomplish this are shown on the following pages.
