APPLICATION AND USE:
Preparation-

STEEL: Thoroughly degrease with a suitable thinner/cleaner using the 2 cloth method prior to carrying out any mechanical cleaning. Blast damaged or corroded areas to near white metal surface as per AS1627.4 Class 2.5. If blasting is not possible, grind with 24-36 grade (grit) discs to a uniform, clean, bright metal surface with a 50-75 microns anchor pattern. Thin the first coat of primer 15% with suitable thinner.
ALUMINIUM: Thoroughly degrease with a suitable thinner/cleaner using the 2 cloth method prior to carrying out any mechanical cleaning. Low pressure grit blast using aluminium oxide or a copper-free equivalent. If blasting is not possible, power disc with 24-36 grade discs to a surface profile of 50-75 micron/ 2-3 mils. (NB Power wire brushing is not permitted as it is ineffective and wires are often steel, leading to corrosion). After being degreased the aluminium surface may be sanded, on small areas, with aluminium oxide papers to present a water break surface and, after drying, pre-primed with Etch Primer. Thin the first coat of primer 15% with suitable thinner.
EPOXY PRIMERS: Sweep blast or abrade with 280 grade paper.
EPOXY FILLERS: Sand with 60-120 grade (grit) paper. Do not wipe down any epoxy fillers with solvent.
FERROCEMENT: Allow to cure for at least 28 days above 20°C/68°F. Ensure structure is free from excess moisture. Remove all laitenance, efflorescence and any other surface contaminants. Thin the first coat of primer 15% with suitable thinner.
BARE GRP/COMPOSITE: Ensure all waxes and uncured resins are removed. Sand with 80-180 grade (grit) paper.
GELCOATS: Sand to remove oxidation and gloss, avoiding cutting too deep into the surface which may result in small air bubbles being exposed which will then require filling.
ZINC/GALVANISED STEEL: On new surfaces/those free from oxidation by-products, thoroughly degrease with suitable thinners using the two cloth method. Oxidised surfaces will require mechanical abrasion to clean thoroughly.
LEAD: Thoroughly degrease with a suitable thinner/cleaner using the 2 cloth method. Rub down with an emery cloth or power wire brush. Pre-prime using Etch Primer where appropriate.
BARE WOOD: Sand with 80-280 grade paper. Remove oil from oily woods eg teak, using Universal Thinners #4. Change rags frequently. Thin the first coat of primer 15% with suitable thinner.
IMPORTANT NOTES:
For further information refer to International Professional Application Manual or the International Boat Painting and Product Guide.:

Method-

Remove blast/grinding/sanding residues with a clean air line & sweep with a clean brush, or vacuum clean for best results. On blasted and rough ground surfaces do not try and wipe with rags and thinners as the rags will catch and leave particles of cloth behind. Apply required number of coats, detailed in the specification sheets, by method chosen or stipulated, allowing required overcoating interval between applications. Thin first coat applications as detailed above.

Hints:

Mixing- Mix the two components thoroughly to an even colour. After mixing, allow to stand for 10-15 minutes before using.
