- The mentioned materials must be used in strict accordance with
the product and health & safety data sheets.
- The wet film thicknesses should be monitored at all stages to
ensure the DFT requirements are met.
- Work should be carried out by competent personnel who have a sound
knowledge of access, preparation and application techniques related
to maintenance painting of architectural cladding. Akzo Nobel Industrial
Coatings Ltd is always willing to answer user’s enquiries
regarding its products.
- The resultant paint finish should be of an accepted high aesthetic
appearance, free of surface defects, runs, sags, curtains, misses,
etc.
- Application should be carried out in weather conducive to painting,
to alleviate problems associated with inclement weather damage,
i.e. rain spotting, blisters, pinholing, blooming (matting off),
etc.
- If the coatings are subject to any of the above, they should be
re-coated accordingly, which may mean re-painting complete elevations
to ensure that a uniform aesthetic standard is achieved.
- Work should be done methodically and with suitable access so as
to allow application to progress with the profile rather than against
it. This should help alleviate patchy finishes and banding. Always
try to keep and maintain the wet edge, to avoid double coating,
fat edges, etc. This will help ensure complete coverage with the
coating system.
- When finishing shifts, or the working day, try to work to a natural
break in the elevation. If no breaks are in the design if the building,
use the troughs of the profile or seams or joints.
- Choose appropriate brush size depending on cladding profile.
- When spraying, ensure all site restrictions are considered and
areas not to be treated should be protected or adequately masked
up. Spray equipment must be capable of achieving tip pressure necessary
to produce good spray atomisation.
- In order to achieve maximum system longevity, preparation should
be carried out thoroughly and diligently, in accordance with the
specifications.
Any holes in the cladding caused by previous signage should be filled
with a suitable filler, or stopped with a rubber grommet.
- When painting is complete, replace any fixing cappings as necessary.
- Where chemical strippers are used, they should be used in strict
accordance with the manufacturer’s product data sheets. Do
not allow to dry on the surface. It is essential to ensure all stripper
residues are removed prior to application of the coatings.
- Ensure all corrosion, white zinc salts (galv. oxidation) and loose
PVC are totally removed and feathered back where necessary.
- Depending on the colour choice, method of application and profile detail, an additional
topcoat of PC5VF Series may be necessary, in order to achieve
maximum opacity and purity of colour. Metallic shades can result in sueding effects due
to pigment orientation if incorrectly applied.
- In the case of sites which have been previously painted, whilst
we can inspect and provide a compatible system to the existing,
we can not be held responsible for any failure or adhesion problems
associated with delamination of the existing coating and any subsequent
failure of our overpaint system as a result of this.
- Where an extra topcoat is required, this should be applied within
48 / 72 hours, to reduce intercoat contamination.
These notes are given as a guide to achieving maximum performance
and obtaining high decorative appearance; however, as every site tends
to be unique in some way, please do not hesitate to contact Akzo Nobel
Industrial Coatings if you should have any query.
This specification is valid for 6 months from the date on the document. Further deterioration
in site conditions may occur after this time, which would require a new specification. All
materials must be applied in accordance with our product data sheets and are supplied in accordance
with Akzo Nobel Industrial Coatings Ltd current Terms and Conditions.
