High-tech, High bond.
When the marine industry specifies a product, durability is high
on its list of requirements. And for the boat owner, durability is
an essential prerequisite for the smooth running of the vessel,
the untroubled enjoyment of passengers and the sheer joy of
sailing. Whether at the wheel of a power boat or at the tiller of
a sailing yacht: there’s nothing quite like that feeling of freedom
when you’re out there on your own, facing the elements ... or
that feeling of total tranquillity with only the horizon ahead and
blue skies above. Times like this make your boat a possession
to cherish, and a valuable asset that you’ll want to protect
against the elements for many years to come.
Water leaks, in particular, can damage your prized possession,
leaving unsightly marks along the hull and causing woodwork
to rot and metal components to corrode. To avoid expensive
repair bills, watertight seals are absolutely essential.
Deck caulking
For timber decks that are completely watertight and weather
resistant, Sika has developed Sikaflex®-290 DC. Extremely easy
to use, this one-part polyurethane deck caulking compound
can be sanded flush with the deck when cured to give a
beautifully neat, clean finish.
Sealing
Resistant to weathering, seawater and ultra-violet radiation,
Sikaflex®-291 is the perfect all-rounder: an all-purpose flexible
marine sealant that bonds extremely well to all the standard
materials used in boat construction. Its outstanding elasticity
ensures a durable, long-lasting seal.
Bonding
Joints that are subject to extreme dynamic stresses require a
high-strength elastic adhesive with good gap-filling capabilities.
Sikaflex®-292, with its excellent shock-absorbing and
vibration-damping properties, has been specially developed to
meet these requirements in the punishing marine environment.
When your safety may depend on it, only the best is good
enough.
Bonding of plastic glazing panels
This is an application that calls for a UV-resistant adhesive with
a high degree of elasticity. Sikaflex®-295 UV combines the
necessary elasticity with exactly the right consistency to
maintain the required bond line thickness, thus ensuring that
thermal movements in plastic glazing panels are absorbed
progressively, without undue build-up of stresses.
Bonding and sealing of mineral glass
Direct glazing of mineral glass requires a purpose designed
adhesive with the right combination of application properties
and performance characteristics. Sikaflex®-296 is a fast curing
high performance elastic polyurethane that is suitable for all
types of mineral glass. It’s high UV resistance also makes it
suitable for backfilling and sealing operations.
Bedding and bonding of panels and sheet materials.
Sikaflex®-298 is a viscous, full-bodied adhesive that has been
specially formulated for the waterproof, flexible bonding of
timber strip decking, deck planking, plastic deck coverings and
prefabricated timber deck panels. It is easy to work with, and
gives professional results every time. The permanently elastic
adhesive layer has a cushioning effect absorbing shocks and
minimizing the transmission of impact sound.
Different products
Same benefits.
Sika pioneered the development of one-component
polyurethanes for marine use. Our global technical resources
have enabled us to produce a wide range of products, each
aimed at a specific marine application. Although the individual
product characteristics vary, they all share the following features:
– One component – no mixing necessary
– Excellent gap–filling capabilities
– Permanently elastic
– Can be sanded and overpainted
– Excellent non-sag properties
– High solids content, low V.O.C.
– Non-corrosive
– For use above or below the waterline
– All are specifically designed for marine use.

After application of Sikaflex®-290 DC
and before skinning occurs, tool the
excess material from the surface of the
deck using a slightly flexible spatula at

Protect the caulked joints from rain

Windows
Application of Sikaflex ®-295 UV Adhesive
Place spacers in position. Depending on the size of the glazing panel, the thickness of the
spacer should be chosen accordingly; approximately 30 Shore A hardness (see diagram
page16).
Apply Sikaflex®-295 UV to the frame rebate or glazing panel using a triangular nozzle of
bead width 10 mm minimum.
Assemble components within 20 minutes of applying adhesive.
To prevent slip down of vertical glazing panels, additional spacers (wood or plastic) must
be placed in the lower rebate during installation. After curing, these must be removed.
The rebate gap must be a minimum of 5 mm (see diagram below).
Fig. B
Clamps and other fastening aids can be removed after 24 hours. After this time, the
expansion gap between glazing panel and rebate can be filled and sealed with Sikaflex®295 UV. This should be done only when the glazing adhesive has reached full cure. This
sealant joint can be tooled to a smooth finish using Sika ® Tooling Agent N. This must be
carried out before skinning of the sealant.
Traces of uncured Sika adhesives or sealants may be removed with Sika ® Remover-208.
208
On no account should other cleaning agents or Sika ® Cleaner-205 be used for this
purpose.
Apply cover strip or Sika ® UV Shielding Tape to cover the bondline in accordance with
Sika recommendation.

Sika or their local distributor.

Apply parallel beads of Sikaflex®-292 at 600 mm centres in an 8 mm x 10 mm triangular

Assemble components within 20 minutes of applying adhesive.
Panels, if required, may be held in place during cure by clamps, support brackets, or by
the use of SikaTack®-Panel Tape.
Clamps and other fastening aids can be removed after 24 hours.
Full service strength is attained after approximately 7 days.

Horizontal Panels
Flat surfaces: Sikaflex®-298. Inclined surfaces: Sikaflex®-291
Apply adhesive to previously prepared surface and spread over area to be covered, using
a spreader with 4 mm triangular notches. The bed thickness may vary depending on the
thickness of any gap that needs to be filled (normally 1–2 mm)
The panel must be positioned accurately within the tack free time of the adhesive and
pressed firmly into place to avoid air-entrapment.
Clamps, weights or screws (removable once the adhesive has set) can be used to secure
the panel while the adhesive sets. Alternatively, the vacuum press method may be used.
After approx. 24 hours the panels can carry their full service load and the temporary
fastenings can be removed. In case vapour-tight substrates are employed, spray a fine
mist (ca. 10 g/m2) onto the Sikaflex®-298 surface to ensure fast curing.
Important: Please refer to the current Sika Technical Data Sheets and Safety Data Sheets obtainable through
Sika or their local distributor.
Note: Exposed seals in wet work areas may require a mildew resistant sealant such as Sika Sanisil.

Aluminium
Aluminium and its alloys are
supplied in sections, sheets, panels,
profiles, and castings. The
preparation instructions depend on
which Sikaflex® product is
involved. For surface-treated
aluminium (chrome-plated,
anodised or coated) cleaning with
Sika® Cleaner-205 is often the only
preparation needed before
bonding.
Plastics
Some plastic materials can only be
bonded with mechanical/chemical
treatments (flaming, plasma,
chemical oxidation), e.g.
polyethylene and polypropylene.
As it is not possible to supply clear
recommendations for bonding of
many plastic compounds, because
of the many different mix
constituents and internal and
external release agents, it is
recommended to contact Sika.
Checks can be made on the
materials to determine the proper
preparation suitable for your
purposes and we can therefore
advise you accordingly.
22
Galvanised Steel
Galvanised steel is either:
■ hot galvanised (strip galvanised),
■ electrolytically galvanised,
■ hot galvanised (hot dip).
For the first two substrates the
base is clearly defined and the
surface composition is mostly
constant, whereas the surface finish
of the third is not constant and the
adhesion properties need checking
periodically. We strongly
recommend pretesting.

Worldwide Sika bonds
the finest craft
Leading manufacturers in the
marine industry were quick to
appreciate the unique properties and
quality of our innovative marine
products years ago – and have been
using them worldwide ever since.
Sika pioneered the development
of a variety of one-component
polyurethanes for marine use.
They all share certain characteristics
including excellent gap-filling
capability and permanent elasticity.
They are also sandable, noncorrosive and can be overpainted.
From the smallest boats to the
largest ships, Sika provides the
watertight solution.
Bonding technology with global experience
