4. Transport and Assembly
a) During transportation of the keels from the foundry to the
boat yard, damage to the epoxy filler and the Intergard
coating will occur. Additional damage may also occur during
the fitting of the keel to the hull.
b) After the keel has been attached to the hull, repair the
damage with epoxy filler and smooth to desired contour.
c) Apply a second coat of Intergard 4424/4423 as
specified in Section 3 (Priming) to all surfaces
of the keel.
d) Allow four (4) hours drying time before top coating.
5. Anti-Fouling Coating
a) Apply one (1) coat of Tri-Lux T.B.T.O. antifouling to all
of the keel and hull.
b) Before applying the Tri-Lux anti-fouling to
the hull, the polyester gel coat should be
thoroughly sanded to provide an anchor pattern
or tooth for good adhesion.
c) Allow four (4) hours drying time.
d) Apply second coat of Tri-Lux anti-fouling as specified
in Section 5. a.
e) Allow 24 hours drying time before immersing boat in water.
f) International Tri-Lux is a vinyl anti-fouling formulated for
ship bottom use. It contains Tri-Butyl tin oxide (T.B.T.O.)
as the toxic agent. Unlike cuprous anti-foulants it may be
applied directly to a primed steel surface without the need
for an additional anticorrosive coat.
