Cedar Impressions Inside Cornerpost
Siding and accessories alone are not meant to be a watertight
barrier. Before applying siding and accessories, make certain
the substrate is watertight. Flash the substrate so that it sheds
water outside the siding.
Cedar Impressions panels are installed from right to left. If the
application situation allows, install both wall sides at the corner
at the same time. This will allow you to make small corrections
to the Inside Cornerpost installation as you move up the wall.
Installing Cedar Impressions Inside Cornerpost
When installing Inside Cornerposts, be sure to run Cedar
Impressions Metal Starter to the inside corner.
Install Cedar Impressions panels from right to left. Install the Cedar
Impressions panels into the inside corners. Leave a 3" gap on each
side of the corner.
Once the panel has been fastened, hook the Cornerpost over the
siding, making sure it is locked into the starter strip. Nail through
the top two holes of the Cornerpost. Continue installing the
Cornerpost as you move up the wall.
When you reach the top panel, cut the Cornerpost to length and
nail it with a color-matched finish nail.
If the Inside Cornerpost is installed before the siding, you will have
to cut the Cedar Impressions panel to fit.
Measure from the edge of the last installed panel to the edge of the
Cornerpost. Add 1-1/4" to this dimension, and cut the panel
to length.
Angle the panel under the Cornerpost and slide it to the left until
the side tabs clear. Then slide the panel to the right until the correct
temperature marks on the panel are lined up.
Fasten the panel to the wall.
