AQUASTOP by VENEZIANI
An effective cure against osmosis.
This brochure should help you to understand what osmosis is and inform you that it is possible to prevent or repair osmosis by using a specific protection system which must be applied very accurately.
Osmosis develops in a very deceitful way and its most evident effects
(blisters) appear only when the disease is already in an advanced stage.
To prevent or cure osmosis, Veneziani has formulated a specific product: Aquastop.
The preventive treatment of osmosis, which practically creates an additional protective skin on top of the Gel-coat, should be applied to new
boats or to boats which have not yet been affected by osmosis.
Especially in the latter case, one must make sure, by means of a special humidity gauge, not to entrap humidity inside of the protective barrier. Entrapped water molecules could result in high pressure against
the protective barrier und cause micro-crevices and therefore water absorption. It is better to carry out this humidity check also in the case
when one suspects that during the anti-osmosis treatment of the boat’s
hull the gel-coat has been sanded too deeply.
You can carry out the procedures of this manual by yourself or contact
a professional boatyard, which is advisable especially in the case of
osmosis repair.
In the latter case, this brochure will be useful to compare our procedure
whit the work carried out.

OSMOSIS
GPR boats
What is osmosis
GRP hulls are manufactured
using a mould. The inside of the
mould is coated with anti-adhesion wax. At first, the gel-coat,
corresponding to the outside
layer of the hull, is applied. The
gel-coat consists of a polyester
resin containing pigments with
the desired colour. Several layers
are applied with spray equipment.
Subsequently, several layers of fiberglass mats are applied. Each
layer is impregnated with catalysed polyester resin. After completion of the curing period, the hull
is removed from the mould.
Osmosis is a phenomenon which
becomes visible through the formation of blisters. The blisters
are filled with water and localized
between the layers of resin in the
hull. In the beginning, the blisters
are small in size and restricted to
a few areas of the hull. When the
phenomenon is progressing, the
blister’s size increases and eventually the whole area of the hull is
affected. The main cause of
osmosis is capillarity which enables water molecules to penetrate into the fiberglass laminate of
the hull. Once inside, the water
reacts with the residual acidic
compounds in the laminate creating a concentrated solution.
More water is absorbed to balan-
Gel-coat with air bubbles
ce the concentration of the solution trapped inside the laminate
(through osmotic pressure). This
causes the formation of the well
known blisters.
Causes of osmosis
The main causes of osmosis formation are the following:
• Residues of non polymerized
resin
• Water soluble contaminants in
the laminate
• Micro-porosities in the gel-coat
or in the fiberglass mats due to
air entrapment during the manufacturing process.

Phases of blistering
The osmotic blistering on boat hulls can be divided into five different
phases. If you study the drawing
shown here below and compare it
with the conditions of your boat’s
hull, it might be possible to carry
out a preventive action suitable to
avoid severe damage caused by
osmosis.
1) Formation of air blisters, often
of small size, in the Gel Coat.
2) Take up of water in the blisters
Formation of blisters
1 Air blisters
2 Water take up
caused by the permeability of the
Gel Coat.
3) Hydrolysis of the gel-coat resin
as well as of the laminate resin
and formation of a concentrated
solution.
4) Increase of the blister size due
to osmotic pressure.
5) Cracking of blister, caused by
the increasing pressure in the blisters.
It is of paramount importance to
choose the right materials for any
repair work. In the diagram shown

How to recognize
osmosis
After each boating season it is
advisable to check the hull of your
boat. When the boat has been
hauled out of water, pressure wash the hull with fresh water and
inspect it carefully.
There are blisters and blisters.
Some blisters occur for reasons
other than osmosis. Old layers of
antifoulings which are porous and
delaminating can cause blistering.
Blisters originating from osmosis
are easy to recognize for their
characteristic dome shape, because they are hard to cut open
and because they contain a liquid
with a strong vinegar smell.
If you are concerned that the hull
is affected by osmosis, remove
the antifouling in 6 spots of the
hull, 3 on each side, at the center, the stern and the bow. For each spot an area of 10 X 10 cm is
sufficient. Measure the humidity
content in the hull with a suitable
humidity gauge. If the hull is affected by osmosis, the humidity
content will be significantly higher
than 10%.

OSMOSIS
HUMIDITY GAUGES
The dielectric constant of water is
75 times higher than that of air
and significantly higher than that
of boat building materials. This
property makes it easy to measure the humidity content of GRP laminates with a suitable humidity
gauge.
PROPERTIES OF HUMIDITY GAUGES
Fast scanning of large areas.
Non destructive testing.
Unaffected by soluble salts.
BOAT HULL INSPECTION
Water adsorption by boat building
materials is a source of problems, which become visible
when the well known blistering
on boat hulls made of GRP occurs.
Humidity gauges have a pad sensor suitable for fast and safe
measuring of the humidity content. A humidity check of the boat
hull can safe a lot of time and money if performed prior to carry out
any kind of osmosis treatment.
Veneziani recommends not to
carry out any treatment as long
as the humidity content of the
hull is higher than 10-12%.
A humidity gauge with pad sensor.
ATTENTION:

in the osmosis
REPAIR SYSTEMI
In the case of new boats, the gel-coat acts as an waterproof
barrier. When osmosis occurs, the gel-coat must be removed
completely and replaced with an Aquastop coating of at least
600 microns.
ATTENTION. On the market you can find sometimes glass laminates of poor quality, which may affect the performance of the
AQUASTOP system.
In this case we recommend to apply an additional coat of
AQUASTOP with brush as a sealer, prior to the application the repair system of 600 microns.
REMARK. It is of outmost importance to comply with the
thickness specified by Veneziani.
You can check the thickness as follows:
Measure the thickness during application with a wet thickness
gauge.
Or
Apply, independently from the number of coats and the application method, the recommended liters, using the theoretical
coverage of AQUASTOP for the calculation: 5m2/L.
Example. For a hull of 30 m 2 you need 6,6 L of AQUASTOP per coat with a total consumption of about 20 L for the whole repair system.

APPLICATION
Aquastop by Veneziani
Aquastop consists of a solventfree mixture of epoxy resins, with
the following features:
• Very high impermeability
• High thickness (can be applied
at 200 microns per coat without
sagging) Aquastop provides excellent protection against osmosis
both as a preventive treatment
for new boats and as a repair
treatment for damaged boats.
If a boat has been damaged by
osmosis, the best advise is to
contact one of the Veneziani
Specialized Application Centers.
Our Main Technical Department is
at your disposal for information
and advice.
Aquastop has been formulated
with a tinting pigment. After application it shows a clear light blue
color. This coloration is useful during painting to understand how
much product is being applied:
the higher the thickness, the
AQUASTOP
Barrier coat for anti-osmosis
protection
CHARACTERISTICS
Aquastop is a barrier coat with high impermeability designed specifically for the treatment of GRP
boat hulls affected by osmosis as
well as for preventive treatment
against osmosis. This product is
resistant against fresh and sea
water and provides also an effective corrosion protection for submerged metal parts (keels, flaps,
rudders, etc.).

darker the color. Aquastop should
be applied within a temperature
range of 15° to 35° C and at a relative humidity below 70%. If during the drying period there is an
abrupt change of climatic condition, this may cause the formation of a sticky layer (amine blushing), which is easy to remove
with water and an abrasive sponge. Wait until dry before resuming
the application of the coating system. If the 48 hours of maximum recoat time are exceeded,
the last coat must be properly
sanded before recoating.

Preventive system
Even if a boat’s hull has not been
affected by osmosis, it may be a
good idea to improve the impermeability of the gel-coat with
AQUASTOP.
Also a new boat’s hull may have
structural defects non visible by
naked eyes, such as air bubbles
or contaminants, and preventing
is much cheaper and less time
consuming then repairing.
1
Degrease the gel-coat carefully
until you are sure to have removed all traces of anti-adhesion
waxes left over from the manufacturing process. We recommend to use abrasive sponges
and DETERSIL, a specific detergent from Veneziani.

Repair system
1
Removal of all damaged layers
(Gel Coat and if necessary also
damaged layers of GRP) by
means of grit-blasting or hydroblasting. Both procedures are effective.
2
Chiseling by means of flat chisel and rubber hammer, a procedure to use in case of very
deep osmosis. After the drying
(curing) period possible protruding glass fibers must be removed by means of disc sanding.
3
Disc-sanding with rotary or orbital disc sanders, using a 36
grade semi-rigid abrasive disc.
This procedure replaces grit-blasting in the case of superficial
osmosis, when removal the Gel
Coat layer is sufficient.
APPLICATION
Curing periods may var y from 2
months minimum to a maximum
of 6 months. In order to verify
the completion of the curing and
the dr ying progress, the humidity content should be checked
once a week and the results
and dates marked with a felt
pen on the most critical hull
areas. Often there is a color
change in the laminate from yellow to a white tint when the
dr ying is progressing.
During the curing period the washing down of the hull must be
repeated at least 3 times, in order to make sure that all bleeding liquid shall be eliminated.
It may be necessar y to open the
laminate in suspect areas by
means of a chisel or a disc sander.
The hull can be considered
dried out when the measured
humidity content is below 10%.
4
Smoothing with an elliptical
planing machine (outfitted with
heat-resistant blades) and subsequent disc sanding with rotary or
orbital disc sanders.
After a drying interval of 16
hours minimum and 48 hours
maximum (at 20°C), level all imperfections with the filler EPOMAST PRO or EPOMAST. EPOMAST
PRO should be preferred for lager
areas because of its low specific
weight. For touch-up filling EPOMAST should be used because of
its fine grain and easy application
or use EPOMAST RAPIDO when
short drying times for sanding are
required (3-4 hours).
Cleaning with DETERSIL and
repeated rinsing with fresh
water, in order to eliminate all
bleeding of acidic solution from
the fiberglass laminate which
could affect the outcome of the
repair work.
10
Application of 1 coat of AQUASTOP with brush, after mixing
of components A + B, taking care
to soak all deeper cavities and
using vertical and longitudinal
cross strokes. The thickness must be 200 microns with a theoretical coverage of 5 m2/L.
7
5
After wards the curing period begins, during which the boat
should be stored outside with a
plastic sheet protection from
the waterline down. If the boat
is stored inside a shed, proper
ventilation and humidity control
is needed. Ar tificial means such
as air dr yers, dehumidifiers or
heaters are not always effective.
6
The humidity measurements
should be carried out dividing the
hull into 8 areas and making 4
measures for each side.
When all damaged layers have
been removed and the curing has
been completed by reaching a humidity content below 10%, the
coating application can start.
9
Application of 2 coats AQUASTOP with brush, short pile roller or foam roller.
10
2
Application with brush of 1
coat of ADHERGLASS, at
about 15 microns and a theoretical coverage of 13,3 m2/L.
Minimum recoating interval before antifouling: 6 hours at 20° C.
If using a foam roller, replace it
every 20 minutes since then it
becomes too soft.
Or application with brush of 1
coat of ADHERPOX, at about 100
microns and a theoretical coverage of 6 m2/L. Minimum recoating
interval before antifouling: 10
hours at 20°C.
11
If 48 hours drying time are
exceeded, sand the surface
before filler application.
8
Sanding of the whole hull with
60 grade abrasive paper.
If using a brush, apply with longitudinal strokes. The minimum total thickness must be at least
400 microns. The recoating interval between coats is 16 to 48
hours at 20°C.
Application of 2 coats of ANTIFOULING. For the right
choice of antifouling please consult the brochure “Maintaining
your Boat” by Veneziani.
The minimum recoating interval
between the second coat of
AQUASTOP and the coat of
ADHERGLASS should be at least
72 hours in order to obtain proper
chemical curing and best impermeability.

The only way to repair a hull affected by osmosis is to remove completely the Gel Coat as well as all deeper layers affected by the osmosis phenomenon. If the osmosis is widespread, it would be useless to
repair single blisters since very likely there has already been water absorption in the apparently non affected areas too. The application of
the repair system is a very difficult procedure. Therefore we recommend you to contact the Veneziani Main Technical Department, which
will inform you about an AQUASTOP CENTER as close as possible to
your location.

CHARACTERISTICS
A superior grade, high performance
antifouling with a hydrophilic matrix,
with a high content of copper compounds as well as an addition of
pure carbon particles, which provide
both excellent antifouling protection
and drag reduction in all conditions.
Effective in warm and temperate

RAFFAELLO
BIANCA RACING
White self-polishing hydrophilic
antifouling
CHARACTERISTICS
Superior grade, durable antifouling
which is both hydrophilic and self-polishing. Because of its high content
of organic biocides, this antifouling
maintains a stable white colour
above and below the waterline and
ensures an excellent antifouling performance. The resin is hydrophilic,
which means lower surface tension
and reduced drag. Effective in warm
table for medium-speed power
boats as well as for sailboats. Not
suitable for boats made of aluminium. The thickness of this antifouling is reduced progressively during
service, avoiding an excessive increase of the antifouling layer also
after the application of several
coats.
