SUPERYACHT SECRETS


Superyacht painters nearly
always apply the paint with a
spray gun, which requires
special breathers and full body
covering. They tend to favour
their own choice of gear, but
always have a new coverall for
each fresh coat. The mask is
full face and makes a tight
seal, with the airline system
keeping the mask free from
condensation, a major
problem for the DIY applicator.

Personal protection equipment
(PPE) is a major requirement of
the professional paint industry,
although not widely followed in
some of the poorer countries
serving the marine sector. The
thinners used in spraying
two-pack paints are
isocyanates, and whilst
relatively harmless in liquid
form can be quite toxic when
atomised. This is why it is best
leaving spray-painting to the
professionals unless you have
all the gear.


The biggest challenge for any
painter is keeping foreign
matter out of the pristine coat.
A full gloss, especially a dark
colour, will mercilessly

highlight every imperfection.
This is why decontamination
extends to every aspect of the
job, including how the tools
are kept.

HOW SUPERYACHTS DO IT


HOW SUPERYACHTS DO IT


THE PBO SOLUTION


THE PBO SOLUTION


Brushes, rollers and other tools
are kept in sealed boxes or
remain in their wrappers until
actually needed.
Paints are only bought in
when required, and stored at a
proper working temperature to
ensure they perform faultlessly.
Everything is thoroughly
washed afterwards. Stirrers are
usually single use and disposed
of rather than cleaned.


The same applies, although this
will be more with brushes and
rollers than spray guns. Order
the paint in when you need it –
you don’t want it lying around
for years – and mix it in a clean
environment, otherwise you can
stir in airborne dust.
Keep brushes and rollers in
sealed packaging until needed,
and open away from any recent
sanding. Keep mixing pots well
away from dust, and store them
in the inverted position.
Avoid using stirrers that are
just lying around. Try and use a
clean stirrer every time, not just
a snapped off piece of plywood
that’s handy!

PPE can be assisted by extra
equipment. This painter is
sanding a work piece over an
extraction table, where air is
sucked down through a metal
grid. With ingenuity these can
be made in a home workshop
using a basic vacuum cleaner

Thinning two packs with liquid
isocyanate thinners is far less
risky than other airborne
sprays, so no special breathing
equipment is required. A
‘solvent resistant’ mask is
always recommended, as it
traps the worst of the fumes,
which can be a bit heady.
Always wear gloves and glasses
and a full coverall. A face shield
is often less prone to fogging up
than goggles, and protects your
whole face against roller splatter.

TOP TIP:
Invest in several pairs of
new coveralls. It is amazing
how many people will do the
sanding and painting while in
the same clothing, and
wonder why bits of dust
and grit end up in the
paint. Fresh paint


  • fresh overalls!


A full-face plastic eye shield
is often more effective than
goggles as it covers a greater
area and doesn’t mist up quite
so easily. This is Coppercoat
being applied

Equipment is scrupulously
cleaned of every trace of
contamination after each
deployment. Spray guns are
test run before the job to clean
out any remaining solvents

Store any mixing pots you
intend to use in a dust free
location, and preferably
inverted to avoid collecting
any moisture

Appropriate face masks/
breathing apparatus is vital for
spray painting
