Wet Out Patch With Resin

Mixing Resin
3. Confirm that you have the correct patch resins – you
will always be mixing a set of two containers, one
marked "Part A" and one marked "Part B" . Both
containers should be marked for the same length
of the patch (32" or 3'). If making a 6' patch you will
need two sets of 3' containers. Confirm the use by
date is still good. Do not use out of date resin – this
can cause an improper patch.
4. Confirm that the patch resins are within the resin
application temperature. If they are outside of the
application temperature take appropriate steps to
bring them within temperature, such as placing the
unopened resin containers in cool or warm water
bath. If they are too warm, the resin will harden more
quickly, and if too cool, the resin will harden more
slowly.
5. Carefully open both resin containers. Pour all of Part
A into Part B. Securely replace the cap on resin and
vigorously shake the container for at least a minute to
thoroughly mix. Record the time that the resins were
poured together.
Wet Out Patch Off Packer
This is the generally recommended wet out method.
Wetting out the patch off the packer typically makes it eas-
ier to fully saturate the patch with the resin. This method
cannot be used for the 3"-4" packer.
1. With the patch in the middle of the table covering,
mix the resin and carefully open. Pour all the resin
mixture on the patch. Do not keep the mixed resin in
the container, it will start to heat up and may rupture
or melt the container.
Using your gloved hands, thoroughly work the resin
into the patch. The patch should turn the yellow resin
color – there should be no white areas. See Figure

Patch End
28. Enough resin is supplied to fully saturate the
patch plus some. This excess resin can be left and
allowed to dry on the plastic table covering.

2. Carefully insert the packer into the patch (Figure 29).
Do not stretch or deform the patch. Position the patch
at the center of the packer assembly. Confirm that
the patch is centered and encroachment zones (as
marked earlier) are visible at each end. It is important
to have the patch centered on the packer to reduce
the risk of an improper patch. Confirm that the patch
is properly placed relative to any containment tube.

3. Gather the excess patch together and fold over neatly
(see Figure 30). At the front end of the patch apply
a doubled over elastic band at the front edge of the
patch and every 1/2" past that until there are 4 elastic
bands in place. Continue to place doubled over
elastic band every 4" along the remaining length of
the patch. Place another 4 elastic bands 1/2" apart at
the other end of the packer. See Figure 31. Doubling
over and proper placement of the elastic bands is
