ensure that it is perfectly clean and dry. Rinse and dry the BC to
clean if necessary.

exactly
twenty minutes
.

2. Check to ensure that the patch extends at least twice the
diameter or length of the hole or tear on all sides.
3. Apply a generous coat of Weld-On 4784® adhesive to the material
of the BC surrounding the hole or tear. Allow this preliminary coat to
set for at least
twenty four hours
.
WARNING: Do not attempt to perform these procedures
using patches or adhesive other than those provided in
the BC patch Kit pn 42611.
WArNiNg: Do not attempt to patch a tear or puncture
which is located directly over an internal baffle, within
50mm (2 inches) of a seam or is larger than 13mm (1/2
inch) in diameter or length.
WArNiNg: Adhesive should only be applied in a
room with plenty of cross ventilation. Carefully read
all cautions on the label of the adhesive and avoid
inhaling vapors.
CAutioN: it is important to prevent any adhesion between
the internal surfaces of the bladder caused by the entrance
of adhesive through the hole or tear. Position the bladder
as needed to maintain a separation of the bladder at the
point of the hole or tear.
5. After
twenty minutes
have elapsed, apply a third coat of adhesive
to the BC material, a second coat to the patch. Wait between
ten
minutes
for this coat to grow tacky and immediately apply the patch
over the hole or tear, using a small roller to press out any pockets of
air that may be present between the patch and BC material. Position
a 5 pound (2.27 kg) weight directly over the patch to apply pressure
and allow exactly
one hour
for the patch to set.
6. Partially inflate the BC no more than 1/2 full, causing the inner
surface of the bladder to separate if adhesion has occurred. Apply a
final coat of adhesive over the entire patch area. Allow
twenty four
hours
to completely cure
,
an then fully inflate the BC to ensure that
leakage is no longer present. If the BC does not remain completely
full for at least
one hour,
immerse it in fresh water to determine the
source of leakage and repair as needed.

note: Do not allow the patch to set more than
one
hour before performing the next step.
