Care for Aluminium Shutters – Anodized Finish or Powder Coated
At the very minimum, cleaning should be done at three to six month intervals (depending on location i.e.. Seaside or inland, rural or industrial area) and is often part of the regular cleaning program associated with items such as the glazing or balustrades of the property. Washing with a mild detergent can counteract atmosphere pollutants like acid rain and seaside atmosphere build up.
General Maintenance of Powder-coated Aluminium: Cleaning is desirable if the fine finish of powder-coated Aluminium is to be preserved. Deterioration of the coating occurs mainly as a result of grime deposition and attack by contaminated moisture, which in a coastal environment contains chlorides and in an industrial or urban environment contains chlorides and sulphur dioxide compounds. Deposited grime absorbs contaminated moisture like a sponge and holds it against the powder-coated surface; this permits the attack to proceed thereby damaging the coating, which cannot be restored without removal. Just as the paintwork on your car needs regular maintaining to stay looking in good condition, it is recommended that the powder coating should also be regularly cleaned to remove air born deposits such as salt, atmospheric pollution or general dirt. The powder coated surface must be regularly maintained in accordance with the powder manufacturer’s data sheets and in areas where there is a high concentration of salt or atmosphere pollutants then a systematic maintenance program meeting AMA 610.1 1979 must be implemented.
Restoring Weathered or Scratched Surfaces
Where practical a suitable polish can be used to restore tired surfaces or areas that exhibit light scuff marks or scratches. Some restoration products we have found especially good are Brasso or for very fine blemishes you may use Autosol. Dulux produce Gloss Up, which has been specifically designed for such a purpose and is applied with relative ease.
Gloss Up does not contain silicon or waxes or other additives that will cause problems further on if recoating the particular surface is undertaken. Appropriate directions are detailed on the container and must be adhered to ensure satisfactory results. Small (spot) Repairs, Touch up of blemishes or deep scratches can be performed with Dulon Acrylic lacquer, either by artist’s brush or fine spray. Most colours have already been matched in two repair systems: Spray cans and Dabsticks. DAB STICKS are a small brush applicator contained in a 15 ml vial pre colour matched to the standard colour range. Dab Sticks are available from Dulux. SPRAY PACKS are pressure packed, also pre colour matched to the standard colour range Spray Packs available from Shutters R Us Franchising Systems (Aust) Pty Ltd and it’s Distributors. Suitable directions for preparation and application are detailed on the individual packages.
- General Maintenance of Finishes
- Blemished or scratched Anodized surfaces can be difficult to repair because of the very nature of the fine finish system.
Brief description of Anodizing processes; Anodizing produces a high quality finish which resists corrosion, abrasion and exposure to industrial, marine and other severe environments. The choice of either clear or coloured anodic films, varying in thickness from 10 to 25 microns, covers a diverse range of applications. We specify a minimum surface thickness of 25 micron.
The client, builder or architect can select the natural matt clear Anodized finish from our standard inventory line or incorporate any of the wide range of coloured finishes as a custom request. Anodizing is an electrolytic manufacturing process that makes it possible to build a heavy inert oxide film into the metal surface. Aluminium is placed in an electrolyte, (an acid/water solution) and an electric current passed through the aluminium, which becomes the anode (positive terminal). Under the influence of the electric current, oxygen forms on this anode and immediately produces a porous oxide film on the aluminium surface. Extending the duration of this process increases the thickness of the anodic film. Once the required thickness of anodic film is obtained, the aluminium is removed from the electrolyte and “sealed”. Sealing is carried out using hot de-ionised water, steam or room temperature nickel fluoride solution. A reaction occurs between the water (or steam) and the porous oxide film. The resultant film is smooth, hard, homogenous and transparent.
- Remove dust with a wet sponge rather than risk micro scratching the surface by dry dusting. Strong stains in metal Stainless Steel or steel may be removed with a commercially available solution such as Dulux Rust off, Diluted Rust Off or other such solutions. Ensure you thoroughly rinse off all residue.( Please read the instructions of use carefully) as we take no responsibility for damage in suggesting any such solutions.
- The surface of the shutters are easy to clean but the axle (the pivot point of each shutter blade) is where dirt can build up. This needs to be thoroughly cleaned with a liberal amount of water to get into the small access areas. This cleaning should be followed up with a small amount of lubricant spray such as silicone spray, WD40 or Lanolin. It is important to maintain the operability of the blades about every 6 months.
- Most marks or surface contaminants on paint work can be removed by the use of a warm, mild detergent or mineral turpentine / white spirit. ( test a small area first).Do not ever use an abrasive solution or scourer pad.
- Always rinse afterwards with fresh water so that the contact time of the cleaning solution is kept to a minimum.
- Stainless Steel or Plated Steel hardware items incl hinges may deteriorate depending on atmosphere conditions. You may apply a clear spray coating of lanolin as a measure of ongoing protection.
The bottom sliding track requires mopping and cleaning out as it does not contain weep holes. The wheels are made of high grade nylon and don’t require maintenance unless some lint or debris gets caught in them, they are located on each bottom corner of the shutter panel for cleaning.
When operating manual actuated Euro 115 blades, E150 blades or Marquis 200 blades in an open and closed position, you must use 2 hands and operate from the middle of the group of blades( ie try to spread the load of the operation of the blade over more than one blade), not from the top or bottom blades. You will find this less effort for you and continue to look after the operation mechanism. The weight and span off these blades must be taken into consideration when operating. Smaller blades are generally easy to operate with one hand centred within the operating group of blades.
Motorized Shutters- please refer to separate user’s manual.
To ensure a good closure of the blades they must be shut firmly (almost slamming shut). The blades are tensioned for normal wind areas and will not close in these conditions, however the blades may move in extremely windy conditions. We suggest you leave the blades in an open position on expected windy days otherwise the shutters act like a sail and may take potential damage from wind gusts.
When sliding the shutter panels past one other you must ensure all the blades are in the closed position, if blades are open and the panels are slammed together this will be considered misuse.
Refer to Owners Warranty Manual.
Care for Timber Shutters
- Painted Shutters: Cleaning with a dust cloth or with a feather duster, as with furniture, is the most important step in maintaining the finish. Dust collection on the surface of the blades or louvres, particularly the exterior, absorbs and holds moisture on humid days and damp evenings. You may use a damp cloth or a little dish wash detergent.
- Danish Oiled or French Rubbed Cedar Shutters: After dusting, you may wish to apply a rejuvenating wood oil to replenish the rich tones of the timber, apply the oil to the shutters and frames then wipe off the excess with a dry cloth.
- Do not wash with water or use heavy waxes. Do not use abrasives such as scourers or steel wool Do not use hot water, alcohol or solvents Do not use excessive water, a light damp cloth is all that is needed Do not use undue weight or pressure on the blades whilst wiping If you have brass kick plates or hardware on your shutter installation be sure to use brass cleaning solution sparingly and not over the wood. If you have stainless steel or painted hardware a damp cloth is sufficient. A very diluted dish wash detergent for painted timber shutters is all that is required to maintain them.
Handling & Temporary Protection – During Transportation And Installation
- General: Powder-coated Aluminium Shutters are delivered to the building site as finished products. Shipped Items are packaged in multiple layers of inter layered protection,then outer packed and then crated. Because of the susceptibility to damage of the powder coating during transportation and installation, special care is necessary in handling these products and should not be allowed to rub or slide against each other during transportation. Powder-coated surfaces should be well protected during transportation by interleaving or pressure packing. If contact with unprotected aluminium does occur, that is, on an uncoated surface, the material should be immediately washed off with clean water and the surface dried. Brick Cleaning: Acids used for brick cleaning can damage the coating and reduce its protective quality. Surfaces should be protected to prevent contact with brick cleaning acids. If contact does occur, the surfaces should immediately be thoroughly washed with copious amounts of clean water
