FLOW CHARTS

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.

These Flowcharts are designed to show typical systems and should not be

construed as specifications for any specific job.

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.

General How-to Information



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 1 – Surface preparation for timber



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.

• OPTION 3 is suitable for small less critical difficult detail

work where 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 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 maynot 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 dueto 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 or so be wet sanded prior to immersion to remove any oxidised paint, which if not removed, could stop the antifouling paint from working correctly. Micron Extra due to its unique resin system should not require this treatment.

• 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

of salinity may have some effect on the eroding

types.

• 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.

Chart 7 – Thinner guide



• 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.

refer to flow sheets for epoxy

sheathed hulls.

• The timber may be sealed with

Everdure 4 coats wet on wet if for

example the vessel will be in fresh

water where potential decay of the

timber may occur. This will also

provide extra protection for vessels

moored in sea water.

• Two coats of Prekote may be required

depending on level of sanding carried

out and the level of finish required.

• 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.

TIMBER

NOTES:

• 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

sufficient film build per coat will if the minimum number

of coats only is applied lead to a very reduced

performance.

• 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.

• With satin finishes the best finish is obtained by applying at

least 2–3 coats of gloss and then 1–2 coats of the satin finish.

• The number of coats suggested is for typical brush

application.

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.



• Regular maintenance by way of touch

up coats will be required for all

exterior varnish work. This time period

will vary depending on exposure

conditions and number of coats of

varnish applied in the first instance.

NOTES:

• It is critically important with stern drive units to ensure that adequate antifouling is applied to all edges and

difficult to get at edges.

• Failure to do so will result in premature fouling due to the physical shape and the operating conditions under

which stern drive units operate.

• Antifouling applied to stern drive units will never perform as well as the same antifouling applied to the hull.

• It will also be found that the antifouling performance will vary between the top half and the bottom half of the

immersed portion due to temperature, abrasive forces and turbulent water flow.

• The number of coats suggested is for typical brush application.

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.

• The number of coats suggested is for typical brush application.

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.



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.

• This will usually entail some form of extraction from

the bottom of the tank, not just a blower pointing

into the top 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

product specified which in turn depends on the

intended end use of the tank.

NOTES:

• This is a system that has found itself suitable

for below the waterline areas

such as keels, trim tabs and even jet units.

• The surface of the stainless steel must be well

profiled and only abrasive blasting will really

suffice.

• For most situations use the standard

specification for STEEL using Interprime

820 as the primer.

NOTES:

• This is an easy low cost option for the painting of the interior skins of

composite boats where easy application is required.

Chart 31 – Two packChain lockers for larger vessels



NOTES:

• This is an easy to apply one product system for chain lockers on larger vessels where the

coating will be subjected to high impact forces from heavy chains etc and an aesthetically good

looking paint finish is not the prime requirement.

• Note that the colour may yellow with age but will not affect its performance.

• Two coats are recommended on steel or aluminium to prevent corrosion.

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.

BARE WOOD: Sand with 120 grade (grit) paper. Remove oil from oily woods eg teak, using Universal Thinners #4. Change cloths

frequently.

LAMINATE: Closed and sound condition laminate only. Note: fibres are impregnated with resin, no fibres exposed. Degrease the

surface (see note below).

GELCOAT: Degrease the surface (see note below). Sand with 80 grade (grit) paper. Ensure sanding debris is removed prior to

proceeding.

POWDER COATED SURFACES: Degrease the surface (see note below).

• 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

NOTES:

• This specification is for use where

a vessel with a sound paint system

is up for a repaint and filling is

required by using spray filler. The

thin coat of Interprotect acts as a

tie coat for the spray filler onto the

possible “unknown” paint and any

exposed substrates.

• The Interprotect must be well cured

and sanded to provide a key.

• The spec calls for one coat of

polyurethane undercoat but more

may be applied if heavy sanding is

to be carried out in an attempt to

„fill” minor depressions etc.

• An optional coat of Interprotect

may be applied if the previous

paint is very worn and/or requires

some slight filling of minor defects

to enable sanding to take place.

• There is no minimum film build

requirements other than for the

Interspray 900 as this system is

simply

a refurbishment over existing paint.
