Installation 
& Finishing Guide
Glue this piece in behind your header to create a pattern 
that fl ows from the face of the moulding around to the 
wall. Note on many patterns such as chair rails this piece 
will be quite small, so use care when cutting.
How Do I Splice a Moulding?
To span longer lengths, you may have to splice mouldings. 
Mitre the joining ends at 45° angles from front to back. 
(Fig.5) One member will overlap the other in a scarf joint, 
creating a vertical face seam in the fi nished installation. 
It is advisable to join moulding pieces over wall stud 
(Fig.6) for additional strength. 
Climatizing your mouldings.
It is advisable that you “climatize” your mouldings prior to 
installation. Mouldings that are made of natural materials 
including MDF and other manufactured products can 
absorb moisture from many sources such as a damp 
garage fl oor. The result of this can be that your mouldings 
can shrink after installation leaving gaps that need to be 
dealt with. A good solution to this is to “climatize” your 
mouldings by stacking them in the room environment which 
they are going to be installed in for at least 48 hours prior 
to installation. Ideally the mouldings should be separated 
to allow air to circulate.
How Do I Install a Moulding?
Install the moulding piece by piece, working your way 
around the room, leaving the nail heads exposed to allow 
for any repositioning. Avoid nailing the last 2 to 3 inches 
of each piece to avoid splitting. In some cases you may 
need to predrill your moulding before installation. Nail in 
the curved or cove part of the moulding to better hide the 
nail holes. Nail mouldings into wood studs or jambs. When 
nailing by hand, any good quality fi nishing nail properly 
countersunk will work well. Nails should not be more than 
1-1/4" longer than the thickness of the baseboard 
What Are Crown Mouldings?
Crowns usually run along the wall at the ceiling, (Fig.7) 
softening the transition from wall to ceiling while adding a 
distinctive look and charm to most rooms. Crowns bridge 
the corners by sitting fl at against both the wall and ceiling 
at the same time. (Fig.7.1) Crowns are available in a wide 
range of profi les and sizes. They can be combined with 
other profi les such as baseboards to create the look of 
custom millwork without the cost. Crowns may also be 
used in mantel and wall trim build-ups.
How To Cut A Crown?
As described, crowns do not 
lie fl ush against the wall. Cutting 
correct 45° mitres is critical. Clamp 
two blocks of wood to the mitre box 
to hold the moulding in place at 
the angle at which it will be installed. 
Once blocks are in place, insert 
moulding prior to cutting, face out 
and upside down (Fig.8). Then cut 
your 45° angles with a fi ne tooth saw. To fl at cut crown 
mouldings with a compound mitre saw refer to the owner’s 
manual that came with your saw.
How To Splice A Crown?
To span longer lengths, you may 
have to splice your crowns. Set 
your mouldings in a mitre box or 
compound mitre saw as described 
in previous section. Mitre the joining 
ends at 45° angles from front to 
back. One piece will overlap the 
other in a scarf joint. (Fig.9), creating 
a vertical face seam in the fi nished 
installation.
How To Cope A Crown?
Trim the moulding in a mitre box at a 45° angle. The 
exposed profi le serves as a guideline for the coping 
saw. To establish a cutting line, highlight profi le shape 
by marking along front edge of profi le with pencil. Cut 
along the line at a 45° angle. (Fig.10.) The adjoining 
piece of moulding is cut at a 90° angle and butts fl ush 
into the corner (Fig.11). 
HANDY TIP
When installing crown moulding a helpful tip is to 
put up a backing which can be made from cut down 
2x4 or any inexpensive wood. You should leave a small 
gap between the crown and the backing to allow for 
uneven walls and ceilings. The backing saves you 
searching for studs and makes for an easier installation.

VERSO
Install the moulding piece by piece, working your way 
around the room, leaving the nail heads exposed to allow 
for any repositioning. Avoid nailing the last 2 to 3 inches 
of each piece to avoid splitting. In some cases, you may 
need to pre-drill your moulding before installation. Nail 
in the curved or cove part of the moulding to better hide 
the nail holes. Nail mouldings into wood studs or jambs. 
When nailing by hand, we recommend countersinking 
size 6D nails. When using a brad nailer, we recommend 
18 gauge nails, and the air compressor should be set to 
70-120 PSI. Nails should not be more than 1-1/4” longer 
than the thickness of the moulding.
