Exterior roof decks, especially those supporting tile or paver systems, require a superior waterproofing solution to prevent costly moisture damage to the underlying structure. The Protecto Deck Primary Waterproof Membrane System, available from A1A Wholesale Supply, is engineered to meet these demands, offering a durable and reliable barrier against water intrusion.

Protecto Deck is a nominal 70-mil thick, self-adhering membrane with a grey color. It is specifically designed for use as a primary waterproofing layer for decks that will be finished with ceramic, porcelain, or dimensional stone tile in thin-set applications, as well as those utilizing pedestal paver systems.

This membrane provides exceptional performance characteristics crucial for exterior deck applications. It has a Class A Fire Rating and passes fungi resistance tests. Protecto Deck exhibits excellent seam strength at 127 lbf/in and robust breaking strength (Transverse direction 780 psi, Longitudinal direction 1,450 psi). It also demonstrates remarkable dimensional stability in extreme temperatures, with minimal length changes at both -15°F (-26°C) and 158°F (70°C). The product ensures waterproofness, passing tests with a 55cm head of water for 48 hours.

Key Features and Benefits for Contractors:

• Primary Waterproofing: Acts as the main waterproof barrier for exterior roof decks.
• Versatile Application: Suitable for thin-set tile (ceramic, porcelain, dimensional stone) and pedestal paver systems.
• High Performance: Nominal 70-mil thickness provides robust protection.
• Fire and Fungi Resistant: Achieves a Class A Fire Rating and passes fungi resistance tests.
• Durable & Stable: Excellent seam and breaking strength, with proven dimensional stability across a wide temperature range.
• 10-Year Limited Warranty: Backed by the Protecto Wrap Standard 10 Year Limited Warranty.

Applications:

• Exterior roof decks requiring a primary waterproofing layer.
• Under ceramic, porcelain, and dimensional stone tile installations using thin-set methods.
• Under pedestal paver systems.

Installation Considerations:

• Surfaces should be clean, dry, and free of dirt and other foreign materials.
• Protecto Deck should not come into contact with solvent-based products, polysulfides, plasticized PVC roofing materials, or high concentrations of resins (pitch)[cite: 1].
• Regular maintenance and inspection are crucial in areas subject to freeze-thaw cycles, snow/ice accumulation, or where de-icing chemicals are used, as neglecting maintenance can void the warranty.
• Outgassing may intensify in recently wet or humid decks; consult Protecto Wrap for recommendations in such conditions.
