Monte is showing how to DIY cladding over Kevin's insulated wall.
To begin Monte applies the flashing. This is a soft malleable metal that
overlaps to protect against moisture. It is placed over door jams and window
frames and along the bottom protecting from water infiltration. Overlap by 75mm
either end of the door jam, then tap in nails at either end. Using a small
wooden block tap the flashing so it moulds to fit.
Next is the sarking. This is reflective foil sheeting that goes over entire
job for more insulation. The sarking is laid horizontally overlapping (shiny
side facing inwards) so the water has no where to go but out. It is attached
with foil clips.
Finally the fibre cement weatherboards are added to finish the job. This
comes in several widths but only one length. Measure, mark and cut. You'll need
to use fibre cement shears. Each subsequent board must overlap the board below.
Nail the boards on, checking the level. The overlap should be about 25mm and
consistent. Leave a 5mm gap at the ends as the boards need room to expand and
contract.
Monte demonstrates 2 different joining techniques. The first one is using
Selleys (weatherboards) No More Gaps. Nail the cladding down first and run
masking tape down either side and fill in the gap with the Selleys No more gaps.
Smooth join with finger.
Another joining technique is with plastic clips that go between the 2 planks
Leaving a 3mm gap tap in.
Finish with an architrave around the door.
