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. Use angle grinder on small areas.
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). Pre-prime with Primocon : thinned 10-
15% with Thinners No.3. 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.
STAINLESS STEEL Thoroughly degrease with a suitable thinner/cleaner using the 2 cloth method prior to carrying out any mechanical cleaning. Grit blast to produce a profile of 50 microns.
EPOXY PRIMERS Re-prime with suitable epoxy primer or 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.
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. Pre-prime with Primocon : thinned 10-15% with Thinners No.3 (15-20% oily woods).
PREVIOUSLY ANTIFOULED SURFACE
In Good Condition Remove all loose material, fouling deposits and any leached layer. Rinse with fresh water and
allow to dry.
In Poor Condition Remove back to sound primers using either suitable chemical strippers or mechanical methods.
Caution: NEVER dry sand antifoulings.
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.
