1. |
Locate area
of corrosion. If corrosion is at the air
to spoil interface, dig up the riser to
approx 1" below the length of area to be
repaired. Note: Proper repair of the
riser piping requires a minimum of 1 inch of
good pipe above and below the pipe wall
surface to be repaired. If the pipe surface
area to be repaired is longer than 12
inches, a second repair kit will be
required. |
|
 |
|
2a. |
Clean and remove loose scale, rust and old paint 1"
above and below repair area using high grit sandpaper,
emery cloth or wire brush. |
|
 |
|
2b. |
Wipe surface area with an isopropyl alcohol or
equivalent substance then wipe dry with a clean cloth. |
|
 |
|
3. |
Measure repair area to determine if one or more kits are
needed for the corresponding length. One kit covers 12" of
repair area per corresponding diameter. Note: If the pipe surface area to be repaired is longer
than 12 inches, a second repair kit will be required. |
|
 |
|
4. |
Mark area
slightly above and below repair area for
proper application. |
|
|
|
5.
|
Open kit, take out bi-pack of Trident-Reinforcing Epoxy,
remove plastic separator and begin mixing / kneading
epoxy inside of pouch until no streaks remain. |
|
 |
 |
|
6. |
Once the epoxy has been mixed thoroughly, put on
enclosed gloves. Using hands, uniformly apply all of the
epoxy to the entire pipe circumference from the bottom
of the marked area up to the top. |
 |
|
 |
|
7. |
Uniformly smooth out epoxy with
a putty knife for proper
coverage. Inspect the entire repair circumference to
insure that no bare spots are exposed. Ideally, you
should have approximately 60 mils of application. |
|
 |
|
8.
|
Remove used gloves and put on the second pair of gloves.
Open Trident-Glass foil pouch, immerse roll in water for
10-20 seconds. |
|
 |
|
9.
|
Begin wrapping with a 50% overlap starting 1" above the epoxied area. Continue wrapping downward 1" below the
epoxied area and then back up until 4 passes have been
applied. Each pass is 2 layers with a 50% overlap for a
total of 8 layers. |
|
 |
|
10.
|
Squeeze and mold the Trident-Glass Outer Wrap firmly
after it has been applied for approx 5 minutes or more,
until the Trident-Glass Outer Wrap becomes tacky. |
|
 |
|
11.
|
Backfill upon
completion of your repair. To paint the
repaired area, wait a minimum of 30 min.
until the Trident-Glass Outer Wrap has
cured. |
