 Mechanically fasten the wings of the corner block with staples or brad nails for extra stability. When
utilizing mechanical fasteners, always position fasteners in an inconspicuous area and vertically to
prevent telegraphing.
Installation of Factory Corners
 Apply adhesive to the back of the corner with either a 1/8” saw-tooth trowel or from cartridge nozzle
and then spreading with a 1/8” saw-tooth trowel to ensure 90% coverage of adhesive while not
spreading within 1/4" from the top of the corner.
 Place corner appropriately and roll with hand roller or smooth with a soft wet cloth to ensure proper
adhesive contact.
Installation of Job-Site Formed Outside Corners
 Position the wall base tight against the wall and mark the length on the back side of the wall base with
a pencil utilizing the wall as a guide.
 Position wall base with the back side up on a flat stable surface.
 Utilize a top-set gouge to remove approximately 30% of the wall base’s thickness along the pencil line
on the side of the line in the direction the wall base will be installed. Remove the excess on each side
of the grove just above the toe of the wall base.
 Utilize top-set gouge to make two stress relief gouges above the wall base toe approximately one-inch
from the bottom of the Vertical Gouge Line. Stress relief cuts should be approximately one-inch long.
 Fold back wall base to pre-form the corner. The toe is to be rolled
upwards which will assist in contouring. The top edge of the cove
base should fit tight against the wall’s surface and the wall base
toe should be rounded and sitting flat against the floor.
 Apply adhesive to the back of the corner with either a 1/8” saw-
tooth trowel or from cartridge nozzle and then spreading with a
1/8” saw-tooth trowel to ensure 90% coverage of adhesive while
not spreading within 1/4" of the top of the wall base corner.
 Install the wall base corner as you would a factory corner above.
Installation of Job-Site Formed Inside Corners
 Install either piece directly into the corner as normal.
 Position wall base for other side of corner without adhesive on the adjoining wall approximately one-
inch from the inside corner.
 Set dividers to corresponding width of gap.
 Slowly move the dividers downward in a straight vertical motion allowing one edge of the dividers to
follow the profile of the installed wall base.
 After the profile has been transferred, use a utility knife to cut the pattern on the uninstalled wall base.
 Apply adhesive to the back of the corner with either a 1/8” saw-tooth trowel or from cartridge nozzle
and then spreading with a 1/8” saw-tooth trowel to ensure 90% coverage of adhesive while not
spreading within 1/4" of the top of the wall base corner.
 Install the wall base corner as you would with a factory corner above.
Installation of Wall Base
 Install corners prior to the installation of the wall base.
 Cut wall base to desired length and fit tightly against corners.
 Apply adhesive to the back of the wall base with either a 1/8” saw-tooth trowel or from cartridge nozzle
and then spreading with a 1/8” saw-tooth trowel to ensure 90% coverage of adhesive while not
spreading within 1/4" from the top of the wall base.
 Apply the wall base in a manner that does not stretch the wall base. Stretching can cause the wall
base to return to its original length and cause gapping.
