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 (102 mm) upper leg.
- Add a 4 inch (102 mm) wide adhesive  ashing to  ash legs less than 4 inches (102 mm).
• Properly integrate  ashing with the secondary WRB according to the WRB manufacturer’s instructions. Use housewrap,
 ashing tape, kickout  ashing, step  ashing, Z- ashing, drip edge, gutters or other items as needed to maintain counter-
 ashing principle.

• Maintain a minimum 1 inch (25 mm) clearance between the end of
the gutter and the adjoining wall to allow for proper maintenance
of the siding. (Diagram 2a)
• Seal ALL exposed cut edges.
• 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 . (Diagram 2a)
