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 Baseboard 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 Base 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 along the back
edges of the base 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 the panel moulding into place. Make sure it is tight against the wall.
By having both edges tight against the ceiling and the wall will provide
consistency.
• Nail though the base 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 base 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 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.
