Siliconizer RC-200

Siliconizer RC-200

Product Description:

A professional grade, ultra-white, elastomeric roof sealer that will provide a weatherproof seal, and adhere to porous substrates and aged metal roofs. In most cases Siliconizer does not require a primer.

A heat-reflective elastomeric coating formulated to protect and waterproof a wide variety of structurally sound roofing substrates, including conventional bituminous built-up roofs, asphalt, aged metal, wood, concrete, and asphalt shingle roofs.  DO NOT USE Siliconizer on EPDM (Rubber) or Polyurethane foam.

Product Advantages:

• 100% elastomeric  • Elongation (ASTM D 412)  • Waterproofs / seals substrate  • Lightweight
• Ultra white  • Heat-reflective  • Algae / mildew resistant  • Prevents leaks

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.
