Installing Mitered Cornerpost

Before applying siding and accessories, make certain the

substrate is watertight. To be properly protected from

precipitation, make sure you have properly flashed the

ubstrate so that it sheds water outside the siding. The

siding and accessories alone are not meant to be a

watertight barrier.

For the best appearance and easier installation, we

suggest you install Mitered Cornerpost as you move up

the wall. If you prefer, you can install Mitered Cornerpost

after the siding has been installed.

1. Install the first Cedar Impressions panel 3" from the

edge of the outside wall.

2. Once the panel has been fastened, lock the first corner

piece over the siding, making sure the corner piece is

locked into the starter strip.

3. The top of the corner must be inline with the top of the

panel.

4. Nail through the top two holes of the cornerpost.

. The right-side corner gap has cut marks at 1/8"

increments. These cut marks allow you to fit the corner

to the different panel height you will encounter as you

finish a course. Trim the corner gap as needed to fit

the panel.

6. Continue installing the corner pieces as you move up

the wall.

7. When you reach the top panel, cut the corner piece to

length and nail it with a color matched finish nail.

Leave 1/4" between the top corner piece and the

cornice receiver.

If you finish the top course of Cedar Impressions siding

with cornice molding, you should also install Vinyl

Carpentry Cornice Cap. Cornice Cap covers the gap

between the two pieces of cornice molding and

seamlessly finishes the installation of the Mitered

Cornerpost.
