Door
Jambs Fixing, Finishing and Storage
Fixing To Framing
GoldenEdge HMR Grooved Door Jambs can be fixed through faces or
edges with screws or nails.
NOTE: Ensure that the timber framing does not have a moisture content
of 20% or more before fitting HMR Door Jambs.
Screwing
The best results are achieved with parallel thread screws such as
the Twinfast or particle board screws. Conventional wood screws
should not be used. Screws inserted into the edges should not be
less than 25mm from the corners. It is important not to overtighten
screws as this will reduce the holding strength.
Pilot Hole
A pilot hole is recommended to avoid splitting during edge screw
fixing. Pilot holes should be drilled approximately 2-3mm beyond
the expected insertion depth.

Stapling and Nailing
Staples and nails can be used effectively for joint fitting. For
best results it is helpful to add adhesive to the joint prior to
assembly. When stapling it is important to have good control of
air pressure to avoid excessive penetration of staples. For nailing
use either annular, grooved or helical nails of 13 or 14 gauge,
for best results.
Adhesives
Where staples or nails are being used, best results are achieved
applying water resistant adhesive to the joint prior to assembly.
Sanding and Finishing
If edge sanding is required, use 120 grit paper followed by 240
or 320 grit paper for best results.
Painting
Prior to priming, stop all nail holes with solvent based wood dough
and lightly sand. Brush, roller and spray application techniques
may be used in accordance with paint manufacturers’ specifications.
