White-Seal RC-865

White-Seal RC-865

Product 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.

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.

Product 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 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

Performance Standards:
• 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 Tips/Hints:

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.

Surface Preparation

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 after application.
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.
