Description
of Application
In modern boats, timber decking is frequently constructed
in the form of prefabricated panels laid over the structural
deck. This method is favoured for reasons of cost.
These panels generally consist
of a marine grade, WBP-bonded plywood backing with strips
of teak or Oregon pine bonded or glued to the face.
Alternatively, they may consist of teak planking held
together by a few layers of glass fibre sheet impregnated
with epoxy resin. They are available either in standard
board sizes or as made-to-measure deck sections cut
and machined to a template.
Another type of prefabricated
panel consists of teak planking with rubber jointing
strips and no plywood backing.
One-part elastic polyurethane
adhesives are ideal for bonding these panels to the
deck. One-part polyurethanes are resistant to sea water,
they possess excellent gap filling properties, and no
additional mechanical fastenings are needed. Once cured,
the adhesive bond is extremely strong, permanently elastic
and waterproof.

Because it is waterproof
and applied to the whole surface of the deck, the adhesive
acts as an additional skin to protect the deck from
attack by the elements. As the deck does not have to
be drilled for screws or bolts, there are no holes through
which water could penetrate and cause damage.
