1 Do not ingest contents of product packaging.
If ingested, seek medical advice.
2 Avoid creating dust when handling, mixing or
sanding as dust from packaged products may
contain crystalline silica. Repeated inhalation
of silica dust over long periods of time may
lead to bronchitis, silicosis or cancer. If dust
is unavoidable, ensure adequate ventilation,
wear eye protection and an approved
disposable face mask that conforms to
Australian Standards AS 1716 Type P1 or P2.
3 If dust or paste causes skin irritation, use
impervious PVC, Nitrite or Rubber gloves.
4 Keep contents out of reach
of children.

Constructing archway framework
Construct archway framework and cover with
a 12mm particle board arch template that is
the same width as the wall framing. (Have a carpenter do this if necessary.)
Marking out arch profile
1 Nail or screw a single sheet of10mm Boral
Plasterboard at every 300mm to one side of
the archway framing.
2 Make sure the bottom of the sheet extends
70mm below the springing line (see diagram).
Mark level position of wall both sides of
opening where arch starts to curve.
3 With a pencil and suitable spacer, mark
the outline of the arch on the back of the
plasterboard sheet, allowing for an extra
10mm around the particle board template
to accommodate the curved reveal strip
along inside of archway.
4 Using a keyhole saw, neatly cut out
the arch.
5 Repeat for the other side of the frame.
Preparation
Changing an existing doorway to an archway
Remove door, architraves, jamb linings etc. to expose the doorway back to the original opening.
Changing an existing wall to an archway
Measure an area in the existing wall frame to allow for an arch opening of approximately
900mm wide (between studs) and 2100mm high (from floor level). This opening is equivalent to
a standard doorway.
Fixing the Arch Bead
1 Bend the Metal Arch Bead to suit the curve
of the arch ensuring the short leg of the
bead is on the face of the main wall surface.
2 Be careful not to leave flat spots in the
Arch Bead.
3 The long leg of the bead fits to the
underside of the arch (reveal strip).
4 Cut the Arch Bead to length, llowing for at
least an extra 70mm below the springing line.
5 Nail or screw the long leg of the bead
through the plasterboard and into the
particle board every 230mm (maximum
centres) and no closer than 70mm below
the springing line.
Installing new plasterboard patch
1 Measure and fix the External Corner Bead
to the straight sides of the archway.
2 Finish all bead applications and joints with
DIY Total Joint Finish.
Making out arch profile
1 Measure the reveal (strip required to form
inner edge of archway - the finished
underside) and cut a strip of plasterboard
wide enough to cover the area and long
enough to extend at least 70mm below the
springing line.
2 Dampening the plasterboard paper liner
along the flexed side of the reveal strip will
assist bending.
3 Apply DIY Cornice Adhesive along the
inside edges of the plasterboard arch and
press the reveal strip into place ensuring
that continuous contact has been made.
4 Nail or screw the end of the reveal strip
to the wall studs at least 50mm below the
springing line on each side of the arch.
