PAINTING
Mouldings can be painted either before installation or after. It is up to the installer.
Use a high quality ALL Acrylic Latex paint. To cover seams, nail holes also use
painter's All-Purpose Acrylic Latex Caulk.
MEASURING AND CUTTING
RPS Crown mouldings should be cut ¼” longer when filling a gap. It would spring into
place.
We recommend using a blade with 60 teeth or better. Make sure to cut quickly
for a clean cut. Quick strokes will avoid melting the material.
Some popular name brand blades that can be used are Dewalt, Diablo, Makita.
If using a compound mitre box, follow the manufacturer’s instructions when mitering
angles for inside or outside corners.
INSTALLATION
High Density Recycled Polystyrene Crown mouldings can be glued, nailed or both. It
cuts just like wood and it also copes just like wood.
• Apply a continuous ¼” bead of Heavy Duty construction adhesive such as
Liquid Nails LN-901 along the back edges of the crown moulding. When
applying glue to seams, wipe away any excess glue immediately before it
can harden. Then once glue is dried, repeat if necessary with adhesive or
filler.
• Hold down Crown moulding into place. Make sure it is tight against both
the ceiling and the wall. By having both edges tight against the ceiling and
the wall will provide consistency and a correct angle.
• Nail though moulding by using a finisher nailer or hammer. Finisher nailer
will speed up the process of installation.
• Continue to install the next piece by making sure they ends butt together
clean. Make sure to glue all joints. It is strongly recommended splicing
Crown mouldings with a Scarf Joint. Scarf joint is achieved by mitering the
joining ends at 45° bevel angle from front to back. On piece will overlap the
other.
• If walls or ceilings are irregular, fill any small gaps with Painter's All-
Purpose Acrylic Latex Caulk.
• When applying the all-purpose acrylic painters caulk to fill in small gaps or
holes from finishing nails, use a putty knife. To clean excess caulk, use a
sponge or clean cloth. After dried, if needed, use a 220 grit sandpaper to
make the surface smooth. This will allow you to touch-up or paint.
