Thick, one component and high performance, urethane ceramic
rubberized elastomeric roof and wall sealer. It will provide
a seamless 100% water proof and weather proof seal adhering
tightly to any surface.
The ceramic composition will significantly lower the
interior temperature by eliminating 90% of the heat
received. It will not crack, crumble or peel despite
exposure to severe weather.
Excellent for water-proofing built-up roofs, polyurethane,
concrete, metal, wood, bonded tar and asphalt shingles.

PRODUCT
DESCRIPTION:
Heat Guard
Exterior is a thick, one component and high performing,
urethane ceramic rubberized elastomeric roof and wall
sealer. It will provide a 100% waterproof and weather proof
seal adhering tightly to any surface without the aid of a
primer. The ceramic composition will significantly lower the
interior temperature by reflecting 73% of all the sunrays
and by eliminating 90% of the heat received (ASTM E-408
C-1371)
BASIC USES:
For
waterproofing and protecting a wide assortment of roofing
substrates that are structurally sound such as conventional
bituminous built-up roofs, polyurethane foam, concrete,
metal, aged galvanize, bonded tar and gravel and or asphalt
shingles.
WARRANTY: 15
year

Surface
Preparation:
Make certain
the roof substrate is thoroughly clean. Remove all foreign
matter and old loose coatings by sandblasting, high-pressure
water blasting (not recommended on shingles) or wire
brushing. Kill and remove all mildew or fungus growth on the
substrate, flush with water and let dry completely.
Substrate must be dry at time of applying primer and
subsequent coating. Be sure roof is well ventilated, in
order to avoid condensation on the roof. Do not use on
rubber roofs. Roof with standing water and improperly
drained areas require annual maintenance (two coats of Heat
Guard Exterior every year).
IMPORTANT:
Even though Heat Guard Exterior will resist standing water
(for 50 hours), do not use on roofs with a slope less than
1/2 inch per foot (If used on roofs with slope less than 1/2
inch per foot, warranty will be void if not re-coated
annually with one coat of Heat Guard™ Exterior).
Mildewed
Surfaces:
Any existing
mildew on the surface must be completely killed and removed
prior to the application of this product. (Any mildew not
removed may continue to grow through the new finish). Scrub
mildewed surface with a mixture of 1 quart of household
bleach with 3 quarts of warm water. Rinse completely and let
dry.
Ponding Water
Areas:
Areas where
ponding water lasts one day or more must be repaired using
roof drains or other corrective measures before applying
Heat Guard Interior RC-200. Less severe ponding areas must
be re-coated with Heat Guard Interior RC-200 annually.
Repair cracks and seams:
Make sure cracks, seams and flashing are clean and dry. With
a putty knife, apply Heat Guard Interior Crack Filler and a
polyester weave over cracks, seams, flashing and around any
standing objects about 2 inches to both sides, and let dry
thoroughly 24 hours before applying Heat Guard Exterior.
Application:
Apply the first coat by pouring container of Heat Guard
Exterior onto the roof and spreading at a rate of 2-4
gallons per 120-240 sq. ft.. Avoid going twice over the same
area. (Be sure to follow drying time between coats or
membrane will be lifted or broken.) Allow 24 hours between
coats as needed. Apply second coat in same manner as first
(by pouring product and spreading it with roller). Second
coat should be at a rate of one gallon per 80 sq. ft. Let
dry 24 hours between coats.
Water ponding
areas:
Areas where
ponding water lasts one day or more must be repaired using
roof drains or other corrective measures, before applying
Heat Guard Exterior Roof Sealer. Less severe ponding areas
must be re-coated annually with Heat Guard Exterior.
Concrete
Roofs:
Repair holes
or any weakened areas of concrete surface with good quality
masonry cement. Paint area to be repaired with Heat Guard
Exterior Bonding Agent CB-950 and let dry. Add one gallon of
Heat Guard Exterior Bonding Agent Blue CB-950 to each fifty
pounds of cement in the mix. Apply concrete mix and let cure
for one week. Repair cracks using Heat Guard Interior
Elastomeric Crack Filler RC-230 and Heat Guard Exterior High
Strength Polyester Weave MP-997 as recommended. Apply one
coat of Heat Guard Exterior. Let dry 24 hours and apply a
second coat.
Metal Roofs:
Remove rust and prime non-galvanized metals with Heat Guard
Exterior Metal Master Primer. For galvanized metals, use
Heat Guard Exterior Super Galvanized Primer SG-664. Replace
loose fasteners. Old fasteners must be covered with Heat
Guard Interior Elastomeric Crack Filler RC-230 and let to
dry 24 hours. Apply Heat Guard Exterior.
Let dry 24
hours and apply a second coat.
Polyurethane
Foam:
Make sure
surface is in good conditions, free of holes and cracks. If
it’s in optimum conditions apply one coat of Heat Guard
Exterior, let dry for 24 hours and apply a second coat.
Asphalt Roofs:
Clean surface, making sure to remove all dirt, oil and
grease. Repair cracks as recommended. Apply one coat of Heat
Guard Exterior , let dry 24 hours and apply a second coat.
Asphalt
Shingles:
Roof must be
clean and completely dry. Apply 2 coats of Heat Guard
Exterior at a rate of 60 sq. ft per gallon. Let dry 24 hours
between coats. Be sure all tabs are completely sealed. If
not, apply Heat Guard Interior Elastomeric Crack Filler
RC-230 and Heat Guard Exterior High Strength Polyester Weave
MP-997 on tab joint as recommended, followed by an
additional coat of Heat Guard Exterior.
Application:
Apply with a Heat Guard Exterior 1/4” Nap Rough Surface
Roller PA-568 or airless spray. Wait 24 hours between coats.
Apply only when temperature is above 50ºF (10ºC). Do not
apply if temperature is expected to drop below 50ºF (10ºC)
before the coating has completely dried. If roof is hot,
spray with water to avoid sealer from drying too fast. Two
full coats are generally needed for proper sealing. Always
apply coats in different directions. Never thin or dilute
from full strength.
Recommended
Equipment:
Use an airless
pump with pressure of 1,500 to 2,000 psi. A fluid delivery
of 1 to 2 gallons per minute with a spray tip of .026 to
.035 will be adequate. Wait 24 hours between coats. The
hoses should be at least 3/8” inside diameter and of the
high-pressure rate type. If the hose length is more than
fifty feet, a larger inside diameter will be required.
Cleanup:
Clean roller and equipment after use with warm soapy water.
Drying Time:
Approximately 60 minutes to touch. Cure time is controlled
by thickness of the applied coating, relative humidity and
temperature. Allow 24 hours between coats.
Weather:
Select a warm, clear and sunny day. Consult your weather
bureau to make sure there is no forecast of rain. Do not
apply after 4:00 p.m. Keep rain- free for a minimum of 6
hours after application.
