LP SmartSide Trim Adjoining Stucco, Brick or Cultured Stone:
When using LP SmartSide trim with stucco, brick or cultured stone, it is
important to use a capillary break so moisture absorbed into the stucco,
brick or cultured stone cannot transfer into the trim.
• Avoid Direct Contact between the trim and stucco, brick or cultured
stone.
• Separate with a minimum 3/8-inch space and a high-quality sealant
(backer rod may be required as per the sealant manufacturers
instructions). Additional space may be required by the manufacturer
of the stucco, brick or cultured stone cladding. (See diagram 8b)
• Other types of impervious material such as aluminum ashing can
be used to separate the trim from the stucco, brick or cultured stone
but the dissimilar materials should be properly spaced to allow for
dierent rates of thermal or moisture-related movement.
• Apply sloped Z-ashing over horizontal trim so water that may get
behind adjoining cladding can be redirected to the outer surface of
the wall.
• Install the trim according to the LP SmartSide Trim and Fascia
application instructions.
• Install the stucco, brick or cultured stone cladding in a manner
consistent with the manufacturers installation instructions.
