Over Masonry
Sub-surface
A minimum 1˝ x 3˝ wood strips are
installed with masonry nails over the
masonry area to be sided (Fig. 1). For
increased decay resistance, use pres-
sure treated furring strips.
Step 1
For horizontal siding, strips should
be installed vertically 16˝ on center.
They should be installed completely
around doors, windows and other
openings, at all corners, and at the top
and bottom of the area to be sided.
Step 2
For vertical siding, furring is essen-
tially the same as for horizontal sid-
ing. Strips should be nailed horizon-
tally 12˝ centers.
NOTE: Furring strips should be
covered with insulated sheathing or
the spaces between the furring strips
should be filled in with insulated
sheathing equal in thickness to the
furring strips. This will provide an
even wall surface for the siding and
help avoid any waviness.
