Description
This product is a styrene acrylic silicone roof and
wall sealer. It is a single component, elastomeric
sealer that will adhere tightly to many surfaces
and provide a thick, high performance, 100%
water and weather resistant membrane, usually
without need of a primer coating. White-Seal™
dries extremely fast by a transition process,
requiring half the time as regular sealers. It will
significantly lower the interior temperature of the
structure by reflecting 73% of the suns’ rays and
reducing heat received by 85%. Product will not
crack, peel or blister even under severe weather
conditions or total joint movement.
Uses
In laboratory tests, White-Seal™ has proven its
outstanding properties during adhesion-in-peel
testing, exceeding every standard (per ASTM C
794 specifications) over a variety of substrates.
This will assure many years of excellent protection
over surfaces such as:
• Modified asphalt membranes
• Built-up roofs
• Asphalt shingles
• Wood roof decks
• Concrete roof decks
• Metal roof decks
Advantages
• Styrene acrylic silicone technology
• High UV ray reflectance
• High resistance to ozone
• Insulates and provides a cool roof
• Excellent wind lift resistance
• Ocean spray resistant
• Good vapor permeability
• Allows substrate to breathe
• Low VOC roof coating
• Excellent pick up dirt resistance
• Ultra fast drying properties
• High resistance to ponding water*
• High resistance to mildew and algae
• Dries ultra white
• Does not usually require primer
Surface Preparation
Make certain the roof substrate is thoroughly
clean and dry. Remove all debris and old loose
coatings by means of sandblasting or
high-pressure water stream or wire brushing.
Remove all mildew, algae or fungus growth with a
1:3 solution of household bleach, flushing
thoroughly with water and allowing to dry
completely. *Surface should not accumulate water
for periods longer than 48 hours. Coat entire roof
deck
with Acrylic Primer Sealer AS-210, if
necessary, at a rate of 250 sq.ft./gal.
Application
Apply utilizing a LANCO® ¼“ nap Rough Surface
Roller PA-568 or airless spray. Allow 24 hours
between coatings. Apply only when temperature
is above 50º F (10º C). Do not apply if temperature
is expected to drop below this level before drying
is complete. On overly hot surfaces, cool with
water spray to prevent sealer from drying too fast.
Two coats are recommended for proper sealing,
applying coats perpendicular to each other. Never
thin or dilute from full strength. When used with
Polyester Fabric Mesh FM-222 for reinforcement,
a proper coat of Aqua-Proof™ MD-863 must be
applied in which to embed the fabric. Consult
Aqua-Proof™ MD-863 technical data or
White-Seal™ RC-865 roofing specifications.
Weather
Select a warm clear day for installation. Consult
weather bureau if needed to ensure there is no
forecast of rain. Do not apply product after
4:00PM. Product must be kept rain free for at
least 6-8 hours after application.
Energy Saving Coating
White-Seal™ RC-865 is an
Energy Star certified roof
coating that will provide many
years of an energy efficient
structure, dramatically
lowering internal temperature
thus requiring less energy
consumption for cooling. Test results in three
major US cities show that White-Seal™ RC-865
will provide a solar reflectance of 82% (ASTM C
1549) after three years and eliminates 89%
(ASTM C 1371) of heat received.
Initial reflectance values are shown lower than the maintained
value due to coating being blue at time of application turning
ultra white after 7 days exposure to sunlight.
White-Seal™ RC-865
Starts Whiter – Stays Cleaner
From the moment of application, White-Seal™
RC-865 provides a strong thick monolithic
membrane utilizing the most advanced
ultra–small particle technology of tightly bonded
molecules, which prevent dirt from embedding on
the surface. The high content of highly reflective
pigments causes it to reflect 73% of all suns’ rays
and eliminates 85% of received heat. This
revolutionary technology makes the finished
surface remain whiter than competing products
Assures a long-term advantage over competing
products.
