3.0 EXECUTION
3.1 INSTALLTION
A.
Follow
manufacturer’s detailed installation procedures.
1.
Determine the position of the plinth by dropping a
plumb line from the center of the soffit beam to the
floor. Mark this point on the floor with a center
of the soffit beam to the floor. Mark this point on
the floor with a “X”. This is where you will center
the plinth so that the top of the shaft will align
with the soffit.
2.
Measure
the overall height. Raise the soffit or porch
slightly with brace for easy installation of the
columns.
3.
Trim
column shaft on bottom end only. Trim with an
abrasive saw. Finish both top and bottom of shaft
with a rasp to ensure an even load distribution
around the entire circumference.
4.
Slide
cap over top of column shaft. Let cap slide down to
rest on neck mold temporarily until shaft is
correctly positioned. (If installing a square
column, slide neck mold over top of shaft to desired
location. Fasten neck mold to shaft. Caulk between
neck mold and shaft.)
5.
Slide
base/plinth onto column shaft from bottom.
6.
Place
column in a vertical position with load centered
over column shaft with even distribution around
bearing surfaces.
7.
If
installation requires that column be secured in
place prior to bearing load, use small L brackets.
Be careful to ensure L brackets do not interfere
with seating of cap and base. Note: To secure
bracket to column, drill hole in shaft and use
through bolts. Do not use screws.
8.
Remove
brace to allow load to bear on column shaft.
9.
Slide
cap up to soffit and attach to soffit using
corrosion resistant type screws. Attach base/plinth
to floor using appropriate fasteners.
10.
Caulk
between the cap and soffit, the cap and shaft, and
the base and shaft for a finished appearance.
3.2
PAINTING/FINISHING
A.
Make
sure all surfaces are clean prior to painting. Use
mineral spirits if oil or alkyd products are used.
Warm soapy water should be used if latex products
are utilized.
B.
It is
necessary to sand the column, caps and bases prior
to priming and painting. Some filling may be
required. Note: The surface on polyurethane caps
and base/plinths must thoroughly scuff sanded with
120 grit sand paper and wiped clean prior to priming
and painting.
C.
Alkyd or
oil based primer and paint are recommended. Latex
products can be used, but additional sanding is
required.
D.
Use a
good, high quality exterior paint. At least one
coat of primer and two coats of paint should be
applied.
E.
Follow
paint manufacturer’s instructions concerning use
within temperature ranges for best results.
F.
Do not
use paint or solvents containing acetone.
3.3 WARRANTY
A.
All fiberglass columns
and polyurethane, fiberglass components, and
decorative capitals have a Limited Lifetime
Warranty.
