Roof Care & Seal Inspections - Holiday Navigator 2003 Owner's Manual

Periodic resealing of the joints and seams is necessary to prevent the
entrance of moisture into the motorhome. Enough emphasis cannot be placed
on this issue. Extreme damage from a water leak can occur rapidly. Never
leave the vehicle unattended with the slide room extended. If the vehicle is to
be stored outside throughout the winter months, a full interior inspection for
water leaks should be made bi-monthly.
Extensive sealing has been done at the factory; however, the normal twisting
and flexing that occurs while traveling may have compromised a seal or seam.
All joints and seams should be inspected at least twice a year and recalked
as necessary. Special attention should be directed toward the roof air conditioning
seals, ceiling and plumbing vents, skylights, roof mounted antennas, windows,
door molding, clearance lights and the beltline molding.
Specific sealant products should be used in the areas for which they were
designed. These items can be obtained from recreational vehicle parts suppliers.
Listed below are some of the more common sealants and the areas in which
they are used. Approved sealants are available at service centers and
authorized dealers.
INSPECT: All joints and seams should be inspected at least
twice a year and recalked as necessary.
WARNING: Some products may contain hazardous materials
which require special handling. Read labels carefully. Follow
all of the product manufacturer's safety requirements.
Sealant Types
Acryl-R:
Acryl-R is used on all roof openings such as vents, skylights, any
roof mounted antennas and ladder roof mounts. The sealant should
be applied only where the equipment bases meet the roof. Clean
the old sealant that is lifting before applying with new. Make sure
the roof is dry and free of dirt. This product is usually found in a
caulking tube. 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. The 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 40-50 in/lbs. The base gasket should
be compressed to approximately one half inch.
Acrylic Sealants (geocel 2300):
This product is used where items are sealed under a painted
surface such as the metal corners of the slide-out room. The
material is specially formulated to allow paint adhesion.
