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.
In laboratory tests, White-Seal has proven its outstanding properties during adhesion-in-peel testing, exceeding every standard (per ASTM C794 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 • Aged galvanized metals
DO NOT USE White-Seal on EPDM (Rubber) or Polyurethane foam.
• 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 dirt pick up resistance • Ultra fast drying properties • High resistance to mildew and algae
• Primer not needed on roofing substrates in good condition (does not include rust and/or corrosion)
• Dries ultra white
• Energy Star Certified - White-Seal is an Energy Star
certified roof coating that will provide an energy efficient structure
for many years. It will dramatically lower internal temperature of the
structure thus requiring less energy for mechanical cooling. Tests
preformed in three major American cities prove that White-Seal
will provide an initial solar reflectance of 73%* and a constant
reflectance of 82% after three (3) years (ASTM C 1549) and reduction of 85% of all heat received (ASTM C 1371).
• Cool Roof Rating Council (CRRC) Certified
- Meets the standards for solar reflectance and thermal emittance (radiative properties) of roofing products.
• Federal Specification Standards
- Meets 100% of Federal Specification TT-C-555B as an effective waterproof coating.
PRODUCT MUST BE APPLIED AT 50 SQ.FT/GAL. IN AT LEAST TWO
(2) COATS 24 HOURS APART FOR A MINIMUM FILM THICKNESS OF 32 MILS DRY
(About the thickness of 12 sheets of paper). Find your square
footage by multiplying the length of an area by the width of that area
(i.e. 10 X 100 = 1000 sq. ft. divided by 50 sq. ft. = 20 X 2 COATS
= 40 Gallons of product). Apply the first coat by pouring coating onto
roof and spreading it at a rate of 50 sq.ft/gal. (32 mils wet). Avoid
going twice over the same area. Allow 24 hours before applying
subsequent coats applying them in the same manner as the first coat. A MINIMUM OF 2 COATS IS REQUIRED WITH A FILM THICKNESS OF 32 MILS DRY.
Steeper pitched roofs will require more applications if 50 SQ.FT/GAL. can not be achieved.
Note: Asphalt roofing: Prior to application over asphalt roofs the
attic area should be very well ventilated (gable vent fan works best) to
prevent condensation on the roof or in between the layers of the
material or decking. Be sure all tabs are completely adhered and
sealed. Areas where the existing material has blistered, buckled or
become wet, must be removed and repaired using similar products or
system. Be sure all edges and grooves are completely coated to ensure a
uniform thickness. If any large holes, dents, grooves or flashing
transitions remain, apply Siliconizer Crack Filler and fabric mesh on
those areas not properly sealed. Additional coats may be need in order
to provide a completely covered and uniform continuous film.
Roofs must have proper drainage and not hold standing water.
Roofs with standing water and improperly drained areas require
corrective measures including but not limited to removal and replacement
of the affected substrate, addition of drains, the use of Ultra-Level
self-leveling compound UL-221, or other approved methods.
Make certain the roof substrate is thoroughly clean and dry. Remove all
debris and old loose coatings by any means deemed necessary
(high-pressure water, wire brushing, etc.). Remove all mildew, algae or
fungus growth with a 1:3 solution of Chlorine bleach (20%), flushing
thoroughly with water and allowing to dry completely.
Patch all cracks, seams and joints with Siliconizer
Crack Filler used in combination with Polyester Fabric Mesh. A base
coat of Siliconizer Crack Filler must be applied in which to embed the
polyester fabric mesh. Apply a 2nd coat of Siliconizer Crack Filler over
mesh prior to application of product.
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
Warranty is valid only when product is applied according to the
instructions of the label (such as applying it at the specified coverage
rate listed above, patching all cracks, seams and joints using
reinforcing fabric mesh). Keep original receipts.
