FLOW CHARTS
What are they?• These flow charts represent the most commonly recommended systems used in the yacht division. Note that some PC or Marine products show up in one or two of the more specialised coating specifications.
• The charts will be updated on an as required basis when new products, deleted old ones or changed specifications occur.
• They will at any time then, represent the latest way of „doing things‟. How can they be used?
• They can be used as teaching tools to explain to a variety of customers how our products fit in with each other.
By selection of specific flow diagrams you can talk about below waterline schemes only, above waterline schemes only or perhaps just how to paint timber or steel boats. The combinations are almost endless.
• They can be used to generate specifications for most requirements simply by finding the appropriate codes in the specification system for each of the products within the flow diagram boxes.
• Individual sheets can be handed out to customers so they can better understand how to paint their boat and what products are required.
• The flow diagrams also match the specifications in the BPG.
Can specifications other than those represented by the flow diagrams be produced?
• Quite simply the answer is yes. It is virtually impossible to present every possible combination of product in a flow diagram format. There will always be cases where standard specifications do not fit in with the exact job requirements.
FLOW CHARTS
Numbering
•
The charts are numbered with gaps so that new ones can be added in later if required. The
Index gives you the chart number and the slide number so you can quickly find the slide
you want. Each slide has the Chart Number on the bottom right hand corner again for easy
reference.
Boxes
•
The flow diagram boxes are colour matched to our labels so that primers are grey,
undercoats yellow, top coats red and antifoulings blue.
•
Boxes with a green outline are optional and can be left out of the system if required without
affecting the integrity of the system. Other boxes are mandatory.
Can the flow diagrams be changed?
•
Flow diagrams should not be changed otherwise non-standard information is being given
out which has been shown in the past to be the cause of many of our problems. If you
need a change refer back to the technical or marketing department as your request may
be something that everybody could benefit by.

Chart 0 – Painting guide overview
NOTES:
This flow chart gives a simplistic overview of the basic International painting systems.
Filling and fairing obviously reduces the simplicity slightly as do the choices of surface preparation and interior versus exterior work on various substrates.
SOME BASIC RULES TO FOLLOW:
Fill and fair direct to most GRP, Epoxy or Timber surfaces but always apply a tie coat of epoxy paint to Aluminium or Steel, usually between 50 and 75 microns dry is recommended.
After applying Microsurfacer or Interfill 835 seal it with Interprotect or Interprime 820. Direct
application of Perfection Undercoat (polyurethane) is not recommended.
Film builds above waterline should be around 200 microns between filler and top coat or substrate and top coat if no filling has been carried out. Film builds below the waterline should be around
250 microns between filler and antifouling or substrate and antifouling if no filling has been carried out.
Apply at least one coat of Perfection Undercoat as a tie coat before applying any two pack top coat. If using a 2 pack system and you wish to apply a
single pack finish apply one coat of Prekote.

Chart 2 –
Surface preparation for aluminium
NOTES:
• Obviously the various methods of preparation have their various uses.
• OPTION 1 is the most highly recommended system giving a good surface for the paint and filling
system to key to. Typically used for Superyacht craft.
• OPTION 2 is very good but requires more care in the preparatory stages to ensure the surface is uniformly prepared and profiled.
Typically used on large workboats and ferries etc. • OPTION 3 is suitable for small aluminium craft and
less critical areas such as interior detail work etc.
• OPTION 4 is suitable for difficult detail work where any form of mechanical preparation is impossible. • For previously coated surfaces remove salt
deposits with fresh water, oil and grease with suitable degreaser and then sand surface to a smooth dull matt finish all over ensuring all edges of worn paint are feathered back to a sound surface. Treat bare substrate as for new work.
Chart 3 – Surface preparation for steel
NOTES:
• Obviously the various methods of preparation have their various uses.
• OPTION 1 is the best method of ensuring total
cleanliness of the metal surface prior to applying a paint and filling system.
• OPTION 2 is very good but requires more care in the preparatory stages to ensure the surface is uniformly prepared and profiled.
• For previously coated surfaces remove salt deposits with fresh water, oil and grease with suitable degreaser and then sand surface to a smooth dull matt finish all over ensuring all edges of worn paint are feathered back to a sound surface. Treat bare substrate as for new work.
Chart 4 – Surface preparation for fibreglass
and composites
NOTES:
1. It is crucial when working with polyester or vinyl ester resins that any surface inhibited resin or in the case of epoxy materials any amine bloom materials are thoroughly removed. Inhibited resin can be indicated by a firm thumb pressure on the surface giving rise to a sticky feel. If unsure wipe surface with International Spraying Thinners and a sticky residue will result if inhibited resin is present. 2. Epoxy amine bloom may be removed with fresh water and/or
detergent water mix. Sanding will not remove the amine bloom and will spread it around the surface.
3. For previously coated surfaces remove salt deposits with fresh water, oil and grease with suitable degreaser and then sand surface to a smooth dull matt finish all over ensuring all edges of worn paint are feathered back to a sound surface. Treat bare substrate as for new work.
4. Peel ply surfaces usually require no further preparation other than a solvent wipe to
remove dust etc being careful not to snag fibres from the rag onto the surface.
5. If the peel ply area is to be used as a bonding area for a high stress loading situation, then sanding with coarse paper is suggested to provide an improved key.
6. In most cases filling may proceed directly to the prepared surface however where vinyl
ester/polyester type fillers and surfacing compounds or any other type of material has been used, a tie coat of epoxy primer may be required before filling/fairing with epoxy fillers is carried out.
Chart 5 – Antifouling guide
NOTES:
• Some of the antifoulings mentioned in the above table may or may
not be available at any particular time due to differing
registration requirements in the various Asia Pacific countries. • For the longest term protection Micron 66 will give the best
performance. Micron 66 should not be used in freshwater areas. • Micron Extra is suitable for trailed boats due
to its very good stability out of the water. The product however will not polish away unless immersion times are consistently longer than about a month.
• It is suggested that antifoulings on trailered boats should if the boat is to be immersed for periods of longer than about a month
• Products such as Trilux 33 and Trilux will generally give lower levels of protection due to the fact that they do not contain cuprous oxide. Where possible such antifoulings should only be used where they have to be i.e. on Aluminium.
• Ablative/eroding types are not specifically
recommended in this chart for use in fresh water as the eroding effects may be variable. Such products rely on the sea water alkalinity to perform correctly. In brackish water either is okay although the level

• Microsurfacer is able to be brushed and rolled because it contains slower solvents than the Interfill 835.
• Interfill 835 is faster to touch dry and cannot reasonably be brushed. Interfill 835 also has an easier mixing ratio than Microsurfacer.

• Note that Antifouling Thinners No 3 can be used as a wipe down
solvent for any two pack product surface prior to applying more primer, undercoat or especially topcoat. The product will remove traces of dust or contamination without leading to print thru or ghost marks.

NOTES:
• It is important that moisture levels of GRP
polyester and vinyl ester hulls be checked prior to commencement of the painting scheme. If levels are high then some blistering of the paint scheme may take place at a later stage.
• Drying out the laminate is the alternative solution.
• The use of Yacht Primer is dictated by the quality of the surface being painted. If for example it is a GRP hull and the gelcoat is aged then 1 –2 coats are recommended to be applied. If the gelcoat is new and in excellent condition then the Yacht Primer can be left out.

recommend that a matching two pack epoxy primer be applied. • In the case of GRP vessels we
strongly recommend the use of Interprotect (an epoxy primer) as a precaution against osmosis.
• One coat of Primocon will provide satisfactory adhesion to the
surface. If major levels of filling and fairing have been carried out then apply up to 3 extra coats of
Primocon to ensure these areas are well sealed.

• On oily timbers such as Teak and Iroko removing the timber oils is essential before applying any varnish. • Priming should then be carried out with the first coat of
varnish thinned as per the label data, usually around 10%.
• The number of coats required varies depending on exposure but for full tropical exposure up to at least 10 coats or more may be required. For interior 3 coats may suffice.
• Note that sanding between coats and/or not applying
• Regular maintenance by way of touch up coats will be
required for all exterior varnish work. This time period may be anywhere between 6 and 18 months depending on exposure conditions and number of coats of varnish applied in the first instance.
• Everdure may be used as a sealer/primer if required but is not an essential element of the system.
• Everdure would typically be used where a higher degree of water resistance was required.
Chart 22 – Two pack
NOTES:
• On oily timbers such as Teak and Iroko removing the timber oils is essential before applying any varnish. Everdure must be applied to seal the timber before application of any Perfection varnish.
• If the timber is not oily then Perfection may be applied direct after normal preparation.
• Perfection when applied direct should be thinned down for the first coat as per label instructions.
This will ensure maximum penetration and adhesion.
• To achieve a satin finish apply 2–3 coats of Perfection Gloss. Sand thoroughly to remove the surface gloss and then apply 1–2 coats of Goldspar Satin.
• The number of coats suggested is for typical brush application.
• Regular maintenance by way of touch up coats will be required for all

NOTES:
• Lead keels present various problems and no guarantees can be given that any system will perform 100%. An alternative to the etch priming / Primocon system is to abrade with 60 grit aluminium oxide paper and sheathe with glass cloth and HT9000. Then paint as for epoxy composites below the waterline.
Chart 27 – Osmosis systems
NOTES:
• For any osmosis protection system it is vital that the underlying
laminate be dry and sound.
• If this cannot be guaranteed then the best procedure is to use the prevention system utilising Epoxy primers and accept that random blistering will occur in the future which can be dealt with on an as required basis.
• Typical blisters can be dealt with by scraping out, washing with fresh water and allowing to dry
thoroughly. Coat the hole with HT 9000 resin mix and then fill with a HT 9000 filler mix. Then apply Epoxy Primer and Antifouling as required.
• The number of coats suggested is for typical brush application.
Chart 28 – Tank systems
NOTES:
• The stripe coat should be applied by brush along weld lines and all corners and is intended to ensure that these difficult areas receive sufficient film build. It also ensures that any pinholing in weld lines etc is filled in.
• It is vitally important when painting tanks that air movement is employed such that solvent vapours are efficiently removed from the bottom of the tank.
• Failure to observe these basic rules will result in poor cure and in
the case of fresh water tanks may lead to a water taint difficult to eliminate.
• For fuel tanks other than diesel do not use this flow chart.
• The number of coats required will depend on the

Chart 32 – Interior Systems (Fire Rated)
Note that fire rating is only valid when system is applied to metal substrates.
STEEL: Degrease the surface (see note below). Gritblast to Sa 2½ - near white metal surface. If gritblasting is not possible, grind the metal surface with 24-36 grit abrasive discs to a uniform, clean, bright metal surface with a 50-75 microns anchor pattern. Use angle grinder on small areas.
STEEL with a Shop Primer: Degrease the surface (see note below). Ensure that the surface is clean from contaminants e.g. rust, dust, oil, grease and dirt. Note: shop primer should have been applied on to a substrate where standard profile requirements have been achieved.
ALUMINIUM: Degrease the surface (see note below).
STAINLESS STEEL: Degrease the surface (see note below). Light gritblast to produce a profile of 50 microns.

SUBSTRATE NOTES:
• The number of coats of Interprotect or any of the chosen polyurethane undercoats required to be applied depends on the level of sanding carried out. Heavy sanding will entail the application of more product to make up for lost film build thickness.
• The total primer/undercoat thickness between filler and topcoat should not fall below 200 microns dry.
• Depending on the exact nature of the substrate an initial prime coat of Interprotect may be beneficial prior to applying filler and or spray filler.

• For special projects the use of Intergard 263 (FAJ034/FAA262) may be permitted where
application of antifouling poses a problem with the recoat times of the Interprotect. This product should be applied at 130 -175 microns wet to give 75 -100 microns dry after the last coat of Interprotect has been applied. Note that the film build of the epoxy primer should not be reduced significantly if the Intergard is used. • Depending on the exact nature of

SUBSTRATE NOTES:
• The use of Interprotect is optional if further build is required as a
sanding primer/filler.
• Reaction Lacquer Semi-Gloss gives a hard wearing surface suitable for all areas of interior use. • There is no specific requirement for
minimum dry film builds provided the surface is in a totally dry environment.
• Film build will however govern the appearance of the final finish and for that reason at least 90 microns dry of primer/undercoat should be present between any filler and the topcoat.
• Depending on the exact nature of the substrate an initial prime coat of Interprotect may be beneficial prior to applying filler and/or spray
