Cleaning and Maintenance

1.Cleaning and Maintenance

(a) In areas within the direct influence zones of salt water, industrial chemicals plants, blast furnaces or other aggressive emission sources, the window should be cleaning at least every three months. In a relatively cleaner environment every six months should be sufficient. In carrying out regular maintenance outside, the internal surfaces are frequently neglected. After a period of time, grime and deposits or from tobacco smoke, coal and oil fires, etc. can discolor the inside window frame and it is recommended that these should be cleaned at least once per year.

(b) Procedure
(i) Wash down with clean warm water containing non-alkaline liquid detergent (in concentration which can be handled safely with bare hands) using non-abrasive cloth, sponge or soft bristle brush. This will remove grime, grease, and any excess chalking. All ridges, grooves, joints and drainage channels where salt or other deposits can collect should be well washed out, thus preventing corrosion sites from occurring!
(ii) Rinse thoroughly with clean water.
(iii) Dry using a soft cloth or leather.

(c) Where a reduction in gloss is observed, chalking is evident or excessive staining has occurred, then an approved renovating cream may be carefully applied with a nonabrasive cloth.

Note: T-Cut or similar automotive paint restorer may be used provided it is not too abrasive! Care must be taken not to abrade sharp corners of sections or areas of beads too heavily where the paint film is normally thinner, and it should be remembered that this operation should not be carried out too frequently. Polish with a soft cloth to restore gloss and colour uniformity

(d) For extra protection a was polish can applied once or twice a year again polishing with a soft cloth to restore glass.

2. Repair

(a) Blisters and corrosion sites may originate from areas where mechanical damage or scratches have penetrated the paint coating through to the aluminum, or from cut bar or butt ends, mires, drill holes or drainage slots, where the aluminum is unprotected (see part 3c)

(b) Procedure:
(i) Use fine grade 120-360 grit abrasive paper to remove corrosion products and any non-adherent paint.
(ii) Wipe with white spirit or approved cleaning solvent.
(iii) Ensure surface is absolutely dry before applying a thin priming coat. Allow 20-30 minutes to "Flash Off" using a fine brush.
(iv) With a fine brush again, touch in the damaged and primed area with an air drying paint It should be recognised that the air drying paint will not posses the same weathering properties as the stoved organic coating, but nevertheless will give a reasonable amount of protection. Their use should of course be confined only to small areas of damage.

3. At the Assembly and Installation Stage

(a) Grease marks; dirt and mastic spillage may be removed using white spirit or an approved solvent, which will not soften the paint film or adversely affect its weathering properties.

(b) Self adhesive tapes and clear lacquers must not be applied as irreparable damage, under certain conditions, can occur to the organic coating

(c) It is recommended that all cut bar ends, mires and butt joints, drainage slots and drill holes should be coated with an air drying paint system including a primer/corrosion inhibitor and a top coat and/or suitable gap sealant to provide protection against the initiation of corrosion sites where the aluminum is exposed. This protection is particularly important if the units are to be fitted in coastal or other aggressive environments.

(d) Fabricators and installers should take a maximum care during assembly, transit and fitting not to damage the paint coating.

Note: Beware swarf on benches, end damage of assembled frames in transit or on site and the careless use of Sharp ended screwdrivers or other tools for forcing "snap-Fit" beads into position!

Note: Beware swarf on benches, end damage of assembled frames in transit or on site and the careless use of Sharp ended screwdrivers or other tools for forcing "snap-Fit" beads into position! If the paint film is unavoidably damaged and bare aluminum revealed, the damage must be repaired immediately using procedure 2b.

4. Points to bear in mind when specifying organic coated aluminum

(a) No organic paint coating, whether polyester or acrylic (or indeed if the substrate is PVC-U) is "Maintenance free" and that especially when installing in coastal districts or areas with high industrial pollution, advice should be given at the time of instillation regarding the frequency and nature of cleaning maintenance needed.

(b) Modern organic finishes which we apply to architectural aluminum are practically identical to the types used on motor vehicles and therefore require a similar degree of care and attention which people typically lavish on their car bodywork. The frequency of cleaning relates directly to the decorative standard which the householder wishes to maintain and also the particular environment where the units are situated.

(c) All paints "Chalk" to some extent in service and a reduction in gloss level will occur. The original finish can be easily restored using the procedure in 1c.

5. Replacement of Broken Glass

Windows and Doors can be re-glazed and the gasket and weather-stripping replaced using materials supplied. Any damage to the gasket or beads may necessitate replacement to retain the weather performance of the product. (Refer to Supplier)
