Check to be sure the existing ceiling can serve as a solid nailing
base. If the existing ceiling is solid, remove all existing moldings
and fixtures from the ceiling and begin by nailing inverted J-channel
along the perimeter of the ceiling area.
If you plan to use light blocks to attach external light fixtures,
install them to adequate backing.
Plan the layout of the ceiling panels to achieve an even balance
or to align with adjacent work.
Use the existing ceiling as a nailing base for the panels. Install
the first panel into the channels at one end of the porch. Be sure
to leave room for expansion. Follow the nailing schedule on the
previous page, positioning the nails in the centers of the slots.
Do not nail tightly. Install the remaining panels. When cutting the
last panel of the first course, be sure to allow room for expansion.
For areas where more than one panel length is needed, use a
double channel lineal.
If necessary, rip cut the final panel and use a snap lock punch to
create tabs every 8" to 10" along the cut edge. Attach utility trim
and insert the panel into the receiving channel.
If the existing ceiling is not solid, install nailing strips to provide a
secure nailing base. Then install J-channel.
If the ceiling panels will run parallel to the ceiling joists, you will
have to install additional 1" x 3" wood furring nailing strips. Install
these nailing strips perpendicular to the ceiling joists, placing a
strip every 1" to 16".
Invert the J-channel and nail it to the underside of wood strips
along the perimeter of the ceiling area.
Install the panels as explained above.
