Fiberglass
Inspect the fiberglass exterior. Periodic
inspection may reveal that flexing of the
fiberglass exterior has created imperfections
in the surface commonly known as “spider”
or “hairline” cracks. A crack that has opened
up to reveal the cloth weave threatens the
integrity of the fiberglass. If the exterior
exhibits signs of damage, prevent moisture
penetration, particularly in freezing climates.
Cover the area using plastic sheeting and/or
tape, and have the damaged fiberglass repaired
as soon as possible.
Roof Care & Seal Inspections
Wherever there is something affixed to the
motorhome, such as the “beltline” or vent
attached on the roof, there is a seal preventing
water intrusion.
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 uses self-
leveling 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
Roof:
Dicor 502 is a self-leveling sealant designed
for use on TPO (Thermoplastic Olefin) roof
systems. This product is used on all roof
openings such as vents, skylights, roof-
mounted antennas and ladder roof mounts. Do
not coat entire roof. Remove old sealant that
is not adhered. Sealant that is secured need not
be removed. Thoroughly clean and dry surface
areas before applying new sealant.
Lay masking tape around the area to be
sealed to limit sealant from spreading beyond
the desired area. Using a caulking gun, apply
new sealant working the caulking gun in a
manner that causes the sealant to fully adhere.
Allow adequate cure time before exposure to
rains.
