Tips for Care
and Installation of MDF Mouldings
It is
important to store all MDF mouldings flat, both for
storage and on the job site. They must be placed up off
the floor in a place where they will not be exposed to
water of draw moisture.
Carbide tip
saw blades and/or cutter heads are strongly recommended
for ripping, cutting, or routing MDF.
Pneumatic
fastening systems with the air pressure set at
approximately 100 pounds work best. This should
countersink most fasteners.
Fasteners
that are recommended and work best on MDF are finer gauge
coated staples with a crown on chisel point and ring shank
or "T type finish nails." These types of
fasteners prevent fiber raise and puckering around the
nail head. Smooth shank nails are not recommended;
however, the installer should consider carefully the
method that best suits his/her particular application.
If the nail
hole has a "volcanoing" appearance, it should be
tapped lightly with a hammer until it is even with the
surface of the trim.
MDF is a man made product
on which face nailing is recommended as opposed to edge
nailing.
A fast drying adhesive (60
seconds or less drying time) should be used when face
niter cust are made around door and window casings.
Alternative installation
for door and window casings would include the use of
casing corner blocks. No glue is required for the type
application.
