Polydeck 160/160SC

The Polydeck^® 160/160SC Pedestrian Traffic Deck System is a liquid-applied, high-performance, polyurethane waterproofing system. The system utilizes an epoxy primer, one coat of a fast setting, chemically cured, two-component, polyurethane elastomeric basecoat with a rubber aggregate that can be applied at any thickness on concrete, plywood and metal surfaces, and one- or two-coats of an aliphatic polyurethane topcoat.

 Polydeck 160/160SC is a high-performance, liquid-applied polyurethane waterproofing system designed for pedestrian traffic decks. It protects surfaces from spalling, freeze/thaw damage, and chemical exposure, while accommodating normal structural movement. Suitable substrates include concrete, plywood, and metal.

 This system consists of the following elements:

·       Primer: Polyprime 2180SC or Polyprime EBF-LV

·       Basecoat: PC-260 (two-component polyurethane elastomeric basecoat with optional sand or rubber aggregates)

·       Topcoat: Polyglaze 100/100C/100SC, Polyglaze AR/AR-OF, or Polyglaze AL-50/AL-50SC

·       Optional Additives: Polyglaze Hardener for fast curing

 Ideal for waterproofing and surfacing of:

·       Balconies

·       Patios

·       Roof decks

·       Sun decks

·       Walkways

·       Primer Application:

o   Polyprime 2180SC: 1 gallon/300 ft² (4 dry mils)

o   Polyprime EBF-LV: 1 gallon/200 ft² for porous concrete

·       Basecoat Application (PC-260):

o   Rubber Aggregate System: 3 gallons/100 ft² for 45 ± 2 dry mils

o   Sand Aggregate Option: 2 coats totalling 45 ± 3 dry mils

·       Aggregate:

o   Rubber granules: 10 lbs/100 ft²

o   Sand: 20 lbs/100 ft²

·       Topcoat Application:

o   First Coat: 1.25 gallons/100 ft² = 15 ± 2 dry mils

o   Second Coat (recommended for warranty): 1 gallon/100 ft² = 12 ± 2 dry mils

·       Total System Thickness:

o   With sand aggregate: 60 ± 5 dry mils

o   With rubber aggregate: 72 ± 5 dry mils

·       Coverage Rates:

o   PC-260: ~33 ft²/gallon (rubber) or 50 ft²/gallon (sand)

o   Topcoat: ~80–100 ft²/gallon depending on layer

·       Primers Compatibility: Use Polyprime 2180SC for general surfaces and Polyprime EBF-LV for porous concrete or when outgassing is a concern.

·       Basecoat and Primer Recoat Window: Within 12 hours. After this, surface must be solvent wiped and re-primed.

·       Fast Cure Option: Polyglaze Hardener accelerates topcoat cure to 2–4 hours.

·       Environmental Limits:

o   Do not apply over unvented metal pans, magnesite, or concrete <3000 psi.

o   Application should occur at least 5°F above the dew point.

·       Material Shelf Life: 1 year in unopened containers at 60–95°F.

·       UV Stability: Polyglaze topcoats are aliphatic polyurethane, indicating UV stability.

·       Substrate Requirements: Structurally sound, trowel finished and sloped for drainage.

·       Pot Life & Cure Times: Not explicitly stated for basecoat; topcoats cure in 2–4 hours with hardener or 8–12 hours normally. Full system adhesion test recommended after 7 days.
