plenty of cross ventilation. Carefully read all cautions on the

1. Inspect the material of the BC surrounding the hole or tear to
ensure that it is perfectly clean and dry. Rinse and dry the BC to
clean if necessary.
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.
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.
4. After twenty four hours have elapsed, apply a generous
second coat of adhesive to the material of the BC surrounding
the hole or tear, and to the glossy surface only of the patch. Wait
exactly twenty minutes.

5. After twenty minutes have elapsed, apply a third coat of adhesive to
the BC material, a second coat to the patch. Wait between five to 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 2.27 kg (5 Lb.) weight directly over the patch to apply pressure, and
allow exactly one hour for the patch to set.
NOTE: DO NOT allow the patch to set more than one
hour before performing the next step.
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, and 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.
