Substrate Preparation
Prepare new surfaces for painting in accordance
with Section 3 of AS/NZS 2311.
For repainting of existing surfaces comply with
Sections 7 and 8 of AS/NZS 2311. This includes
cleaning down with sugar soap, treatment of mould
growth, rubbing back existing painted surfaces
with abrasive paper and patching and priming of
damaged surfaces.
Order of work
Complete clear timber nishes before commencing
opaque paint nishes in the same area.
Protection
Remove door furniture, switch plates, light ttings
and other xtures before starting to paint, and rex
in position on completion of painting.
Restoration
Clean off marks, paint spots and stains progressively
and restore damaged surfaces to their original
condition. Touch up damaged decorative paintwork
or misses with the paint batch used in the original
application.
Fillers
Provide a ller tinted to match the substrate if the
nish is transparent.
Paint application
Apply the rst coat immediately after substrate
preparation and before contamination of the
substrate can occur. Ensure each coat of paint or
clear nish is uniform in colour, gloss, thickness and
texture, and free of runs, sags, blisters, or other
discontinuities.
Number of coats
Apply additional coats if necessary at no extra cost
to achieve the required total lm thickness and
satisfactory opacity.
Priming before xing
Timber: Apply a rst coat (two coats to end grain)
to exposed roof trim, timber doors including tops
and bottoms of doors, associated trims and glazing
beads before xing in position.
Steel: Apply a priming coat of zinc-rich organic
binder to APAS - 2916.
Repair of galvanizing
If galvanized or zinc-coated surfaces have been cut
or welded after galvanizing, prime the affected area
with a zinc-rich organic binder to APAS - 2916.
Paint system description
If a system is referred to only by its nal coat (for
example by the manufacturer’s brand name, the
APAS specication code or the generic name)
provide stains, primers, sealers and undercoats
which are suitable for the substrate and are
compatible with the nish coat and each other.
Painting Schedule
Refer to the Project Specic Requirements for
painting, where applicable.
