Remedial painting of powder coated MetalworkApplication advice and Health and Safety information sheet

These are basic tips for the persons using the kit as supplied. It is assumed that the user is familiar with the health and safety requirements and has the knowledge of how to use the material supplied. If you are unsure of how to use any part of this kit then please seek the advice of an experienced and qualified person.

Some paint kits are supplied with the basic requirements for personal protection when applying the remedial paint. Please check the contents of the kit to make sure that everything is in the box. Please read the information on thetins/aerosols before commencing work.

APPLICATION ADVICE

BEFORE YOU STARTCheck that you have all the materials required for the job and all Personal Protective equipment required. Apply remedial paints on a warm and windless day if outside with no prospect of rain.

PREPARATION – to remove lumps and spikes in the substrateUsing a file and abrasive cloth, rub back the lump or spike until the surface feels smooth. Blend in any edge in the paint that could lift. For larger areas work back to a natural break in the material, i.e. a corner, edge etc. This will improve the look of the finished job. Liquid paint and aerosol paint should be thoroughly shaken for at least 2 minutes prior to application and regularly during the application.

GENERAL APPLICATION GUIDELINESShake can for at least two minutes before use. Ensure surface to be sprayed is clean, dry and free from any corrosion. Test spray on an inconspicuous area for colour match. Carefully mask off adjacent areas. Spray several thin coats, from a distance of 25-30 cm, keeping the can moving from side to side at all times. Drying time will vary according to type of paint, film thickness and ambient temperature.

REPAIR OF SMALL AREAS WHERE THE DAMAGE IS NOT THROUGH TO THE SUBSTRATEUsing a very fine abrasive cloth (240, 320 or 600 grit), locally abrade the surface to provide a key for the paint. Apply the paint using a fine brush or light layers to avoid excess paint outside of the damaged area. Repeat if necessary to achieved required build and colour.

REPAIR OF LARGER AREAS AND DAMAGE WHERE THE SUBSTRATE HAS BEEN EXPOSEDUsing a progressively fine abrasive cloth (120 grit progressing to 240, 320 and finally a 600 grit), locally abrade the surface to provide a key for the paint whilst blending the edges of the damaged area. Correctly prepared areas will have no noticeable “step” between the substrate and the surrounding area of sound paint. Apply the colour coat in several light layers whilst following the general application guidelines. Continue to apply layers of paint until the required depth of colour is achieved.

TIS1: Nov 2014

As with any organic coating, in order to retain the aesthetic qualities and the expected long term durability of the powder coating system it is important that the coating is cleaned regularly.

The frequency of cleaning depends upon the environment in which the powder coating is in service.

• For areas of ‘normal’ urban environment we recommend a maximum period of 12 months between cleaning operations, unless any undue soiling is apparent on the coating, in which case cleaning should be more frequent. • In areas of high pollution, marine and swimming pool environments cleaning should be carried out every 3 months.• For areas with an “industrial” environment we recommend that cleaning should be carried out every 3 months.

It should be noted that one of the conditions of any guarantee is that the coating is cleaned at the specified frequency and that proof of cleaning is retained by the building occupier.

These cleaning records would be needed should a claim arise against the guarantee.

Cleaning of the powder coating is an important part of the routine maintenance of any building. It is for this reason that we advise that only companies who specialise in this type of work are used for large cleaning operations.

CLEANING OF SMALL AREAS

The powder coating can be cleaned by using a solution of mild detergent in warm water. All surfaces should be cleaned using a soft cloth, sponge or a natural bristle brush.

Abrasive materials should be avoided as they will damage the coating.

If the powder coating has become heavily soiled it may be difficult to remove this soiling using only a mild detergent.

In order to overcome this problem, several commercially available cleaners have been tested:

• Ajax Cream• Liquid Gumption• Flash (in water)• Ajax Liquid (in water)

Should oil or grease deposits exist, then strong solvents must not be used to remove these.

It is recommended that, in all cases, such products are reserved for heavy soiling only and should be tested on small areas of the soiled powder coating first to assess their efficiency. After application all detergents and cleaners must be thoroughly rinsed away with clean water.


Cleaning of the Powder Coating SystemTechnical information sheet

TIS2: May 2014

Successful powder coating on galvanized steel starts with good design. More than most materials, the appearance and performance of the galvanized and powder coated duplex system is influenced by considering the design and manufacturing process at an early stage of a project.

RELEVANT STANDARDS

• BS6497 Powder coating on galvanized steel substrates. The UK standard, now discontinued.

• ISO 13438 Powder coating on galvanized and sheradized substrates. The European standard.

• ISO 12204 Design for painting.

• ISO 1461 Hot dip galvanizing.

BASIC DESIGN CONSIDERATIONS

SHARP EDGES

Sharp edges are commonly caused by laser, water and plasma cutting of steel.

Sharp edges have been shown to cause fracturing of the zinc and localised thinning of the powder coating around the edge for up to 10mm.

The sharp edges should be “broken” by either (a) champhering the edge (good) or (b) making a 5mm radius (best) to allow the zinc and powder coating to grow and flow around the edge. An additional benefit of champhering the edges is that they are much more comfortable to handle and safer in use especially in balustrade components.

Design for galvanizingTechnical information sheet


TIS3: Nov 2014

ZINC FLOW

Zinc surfaces look and cover at their best when zinc can flow uninterrupted along the surface.External stiffeners should have their corners cropped at the web to allow zinc to flow and thus avoid dead pockets of air and ash.

VENTILATION

Molten zinc is 93% of the specific gravity of steel, which means it’s difficult to sink. A small amount of air trapped in a hollow steel section could mean that the fabrication will float and not galvanize correctly. This will leave a burned surface, incomplete internal protection and poor surface finish.

Incorrectly vented fabrications are the most common fault of a fabrication and the most important to get right. Your galvanizer may refuse to process material that is incorrectly vented.

CLOSED HOLLOW SECTION FABRICATION

Holes should be within 10mm of each end of the section and diagonally opposed.

Surface Contamination of Material for Galvanizing and Powder Coating

Contaminants such as, oils, greases, dirt and silicon are well known to affect the galvanizing and powder coating industry.

Generally most galvanizing and powder coating companies will have a pre-treatment that removes loose surface contamination, light oils etc, although there are situations where even the best system will not remove heavy contamination.

HOW TO AVOID SILICON AND GREASE CONTAMINATION

• Do not use silicon containing maintenance lubricants and anti-spatter spray.

• Do not use high tack tapes directly on material.

• Remove grease from the area around the weld point before welding.

• Remove grease from material to be shot blast.

• Remove weld slag.

• Remove ink and paint marks.

In addition, the following are common causes of contamination:

• Food – such as crisps – leaving grease on people’s hands

• Hand creams

• WD40

• Fats used in grinding

SILICON

Silicon is very difficult to see. It is inert up to about 900 degrees Centigrade and resistant to acids. It cannot be dissolved in water or removed by steam.

• If silicon is present on the surface of material before galvanizing or powder coating then pre-treatment or acid pickling will not eliminate it and the resulting galvanized or powder coat finish will be flawed.

• Powder coated surfaces will be contaminated with what are known as “Fish eyes”, small craters in the surface.

• Galvanizing will be incomplete in areas of contamination, as molten zinc cannot reach the base metal.

GREASE, HEAVY OILS, CUTTING OILS, MILL SCALE, WELD SLAG

These contaminants are not removed by powder coating pre-treatment systems or acid pickling before galvanizing.

• The results will be the same as those described for silicon contamination.

• Welding of greasy metal will result in a baked on layer of grease that is very difficult to remove and will act as a barrier to formation of the zinc surface.

• Shot blasting of greasy material will result in an inferior surface finish.

• Shot blasting won't always remove mill scale. Mill scale is hard to see on bare steel but becomes noticeable after powder coating. Good quality steel should be free of mill scale.
