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

substrate 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 Cornerposts as you move up

the wall. If you prefer, you can install Mitered

Cornerposts 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, hook the corner

piece over the siding, making sure the corner piece is

locked into the starter strip.

3. Nail thr

ough the top two holes of the cor

nerpost.

4. Continue installing the cor

ner pieces as you move up

the wall.

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

length and nail it with a color matched finish nail.

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

cornice receiver.

If a course of siding ends at an outside corner that has a

Mitered Cornerpost installed, you will have to cut the

Cedar Impressions panel to fit.

6. Measure from the edge of the last installed panel to

the edge of the Cornerpost.

7. Add 1-1/2" to this dimension and cut the panel to

length.

8. Angle the panel into the Cornerpost and slide it to the

left until the side tabs clear.

9. Then, slide the panel to the right until the correct

temperature marks line up.

10. Fasten the panel to the wall.

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.
