Step 2: On a wall section where two
pieces of crown molding need to be
joined, it is easier to cut the miters first
and leave the straight butt joint as the
last cut. When using Crown Molding
with Bullnose, use Bull Adapters as
shown above. Step 1: If required by local codes, paper tape or fire tape the inside corner prior to installing the
crown molding. Always wear safety glasses when using miter saws, staple guns, or spray
adhesive. If necessary, attach some plywood to the miter saw so the part is supported as shown.
Break your saw to the left for a right inside or left outside corner. Break your saw to the right for a
left inside or right outside corner. For additional support, place the foam spacer pieces near the
blade. Use a fine tooth cross cut blade. To ensure accuracy, make the miter cuts slowly. Typically
a 90º inside or outside corner will require setting the miter saw to 45º. Most corners are rarely a
true 90º so you may need to adjust the angle and make some practice cuts first.
Step 3: You must apply a 1/2" bead of high
quality white paintable adhesive caulk, such
as Trim-Tex 700/710 caulk or Big Stretch from
Sashco, along the front edge of the top flange
of the Crown Molding. Apply 847 Spray
Adhesive to the mud leg.
Step 4: Starting at any miter joints,
carefully install the crown molding
taking care to keep the product square
to minimize gaps at miter joints. Apply
pressure to the bead along the top
edge to bond the crown molding to the
ceiling and then pressure along the
mud flange. Staple the mud flange
every 6" with 1/2" divergent staples.

Step 5: Wipe excess caulk that squeezed out
from the top flange. Then caulk along the top
edge of the crown molding, the inside and
outside corners and any butt joints.
See graphic to the right. In extreme
settling or movement conditions, the caulk
may crack along the edge of the Crown
Molding. Re-caulk as needed.
, Apply
compound along the mud flanges. For the
ultimate in compound performance, add Mud-
Max Drywall Compound Additive to your mud.
Paint the crown molding with a high quality
latex paint.
