Poly-I-Gard 246 Vehicular Traffic Deck System

The Poly-I-Gard™ 246 Vehicular Traffic Deck System is a liquid-applied, high solids, moisture-cured waterproofing system. It utilizes an epoxy primer and one easy-to-use high tensile, aromatic polyurethane to complete the system.

 Poly-I-Gard 246 is a liquid-applied, high-solids, moisture-cured, elastomeric polyurethane system designed for waterproofing and protecting vehicular traffic decks. Its purpose is to protect concrete surfaces from spalling, freeze/thaw cycles, chemical attack, and abrasion while accommodating structural movement.

 The complete system consists of:

·       Primer: Polyprime 2180/2180SC or Polyprime 21. For rough/porous substrates, Polyprime EBF-LV is recommended.

·       Joint Treatment (if applicable): PC-260 elastomeric caulk and reinforcement with Straight Jacket Tape.

·       Intermediate Coat: Poly-I-Gard 246

·       Topcoat: Poly-I-Gard 246 (multiple coats with aggregate broadcast)

·       Vehicular traffic decks

·       Concrete roofs and decks over occupied spaces

·       Balconies and walkways

·       Stairs and helicopter pads

·       Primer Application: 300 sq ft/gal (0.14 L/m²), 4 ± 1 dry mils (102 ± 25 microns). For porous concrete, Polyprime EBF-LV is used at 200 sq ft/gal (0.20 L/m²).

·       Base Coat (Phase 3): 1.25 gal/100 sq ft or 80 sq ft/gal. Minimum 14 ± 2 dry mils (356 ± 51 microns).

·       Traffic Coat (Phase 4–5): 1 gal/100 sq ft or 100 sq ft/gal. Minimum 12 ± 2 dry mils per coat (305 ± 51 microns), aggregate broadcast for slip resistance.

·       Topcoat (Phase 6): 1.25 gal/100 sq ft or 80 sq ft/gal. Minimum 14 ± 2 dry mils.

·       Finished System Thickness: 40 ± 5 dry mils overall (1016 ± 125 microns); 52 ± 5 dry mils (1321 ± 125 microns) for high-traffic zones, excluding aggregate.

·       Temperature & Humidity: Application must occur at least 5°F (3°C) above the dew point. At 75°F (24°C) and 50% RH, the system allows light foot traffic after 24 hours and full vehicular traffic after 72 hours.

·       Surface Limitations: Do not apply on-grade slabs, slabs with buried membranes, or any substrate with compressive strength under 3000 psi. Asphalt surfaces require priming with Polycoat PC-IM 129.

·       UV Stability: Not specified; typically aromatic polyurethanes are not UV stable unless otherwise stated.

·       Coverage Rate & Thickness: Overall coverage is approx. 80–100 sq ft/gal per coat depending on the application phase. Wet film thickness aligns with dry mil targets using proper equipment (notched trowels/squeegees, phenolic rollers).

·       Pot Life and Cure Time: Not explicitly stated; curing phases suggest 24 hours for foot traffic and 72 hours for full cure at standard conditions.

·       VOC Compliance: Multiple versions (e.g., SC, EBF-LV) allow for VOC regulation adherence across jurisdictions.

·       Fire Rating & Approvals: Class A Fire Rated (ASTM E108, UL 790), ICC-ES ESR-2785, LA City RR#25171, ASTM C957 & C1028 compliant.
