Sealant Replacement:
Carefully remove sealant that is cracking,
aking, bubbling, peeling or pulling away from
the surface. The area underneath the removed
sealant will need to be cleaned and dried 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
manufactures. 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
Acryl-R
®
:
Product Manufacturer Schnee-Moorehead
Part # 5504. Used on all roof openings such
as vents, skylights, roof-mounted antennas and
ladder roof mounts. Sealant should be applied
only where equipment bases meet the roof.
Acryl-R is generally available in a caulking tube.
Two colors are available - white and silver. Silver
is used on items mounted on the forward painted
area of the roof. White is used at all other points.
Remove old sealant that is not adhered.
Sealant that is secured need not be removed.
Dirty or damp surface areas will compromise
sealant effectiveness. Thoroughly clean and dry
the surface area before applying new sealant.
Lay masking tape around the area to be sealed
to stop sealant from spreading beyond the
desired area. Using a caulking gun, apply new
sealant as needed. Work the caulking gun in a
manner that will cause the sealant to fully adhere
to the applied area. Allow adequate cure time.
Roof air conditioners use a closed cell foam base
gasket and do not require sealant. The roof air
conditioners should be regularly inspected for
tightness at the four mounting bolts, one located
in each interior corner of the air conditioner
roof opening. Torque speci cation is 40 to 50
in/lbs. The base gasket should be compressed to
approximately a 1/2".
Acrylic Sealants:
Product Manufacturer Geocel Part # 2300

painted surface such as the metal corners of
slide out rooms and roof mounted awning
brackets. The material is specially formulated
to allow paint adhesion.
