2012 Trip
There are many types of sealants and each
has a specific use. While the beltline uses a
silicone or urethane base sealant to prevent
water intrusion, roof openings use an acrylic
based sealant. Moisture intrusion can occur at
any time for a number of reasons. Therefore,
regular sealant inspection and maintenance
will greatly reduce the likelihood of moisture
intrusion and costly repairs.
The motorhome is sealed at the factory.
However, extreme weather conditions can
shorten the life of the sealant. Harsh road
conditions can compromise sealant integrity.
Maintaining sealant is part of regular
motorhome maintenance. Inspect all joints,
seams and openings at least once every six
months. While sealant integrity may appear
fine, a small void under the right conditions
can quickly cause major damage. Make a
full interior inspection for signs of moisture
intrusion every two weeks if the motorhome is
in storage.
CAUTION:
Inspect exterior seals, seams and joints
for sealant integrity at least twice a
year. Make a full interior inspection
for water leaks every two weeks while
the motorhome is in storage.
INSPECTION:
Surface must be clean and dry. Inspect
seal for voids, cracks, bubbling,
peeling or pulling away. Sealant that
looks fine without imperfections is
acceptable for continued service.
Sealant that is old, cracking, flaking or
bubbling will allow moisture intrusion
and must be repaired.
WARNING:
Inspecting sealant will require use of
a ladder or scaffold assembly. Roof
access is also required. Follow proper
safety measures accordingly. Exercise
extreme care whenever using a ladder/
scaffold assembly. Avoid getting on
the roof if it is icy or moisture laden
as the surface can be very slick. Use
judgment if inspection is considered
dangerous. Have the motorhome
inspected or sealed (if necessary) by a
qualified service technician.
Sealant Replacement:
Carefully remove sealant that is cracking,
flaking, bubbling, peeling or pulling away
from the surface. The area under the removed
sealant will need to be clean and dry before
applying new sealant. Applying new sealant
over a dirty or moisture laden surface will not
allow proper adhesion. Sealant application
may require simple hand tools and paper
towels or rags for cleanup. Some sealants may
be labeled hazardous or require chemicals
for cleanup. Follow all of the manufacturer’s
warnings and precautions when dealing with
these substances.
WARNING:
Some sealants may be labeled
hazardous or require use of petroleum
distillates for cleanup. Use proper
precautions as suggested by the sealant
or chemical manufacturer. Use of
protective eye wear, gloves, respirator
or open ventilation may be required.
Use judgment when working with
chemicals. If health limits exposure to
chemicals or inhibits skills or abilities,
employ a qualified service technician
to perform the tasks.
Sealant Types
General Maintenance – Roof: Titan 76 -
AM Brush Grade Slow Cure MS
This product is used for large roof openings
such as around vents, skylights, any roof
mounted antennas and ladder roof mounts.
Clean the old sealant that is lifting before
applying the new. Make sure the roof is dry
and free of dirt. This product is found in a tub
container. Care should be used when near an
edge, as the product will spread out. Masking
tape may be used to mask around area to avoid
mishaps.
WARNING:
Consult manufacturer data for
application and safety instructions.
For small areas of maintenance various
rubber sealants are available in a tube. These
products are available at RV supply locations.
General Maintenance – Roof Air
Conditioner:
Roof air conditioners use a closed cell foam
base gasket. No sealants are required. The
roof air conditioners should be checked for
tightness by the four mounting bolts located in
each interior corner of the air conditioner roof
opening. Torque specification is 40 to 50 in/lbs.
The base gasket should be compressed to about
½".
