Description
The Polydeck® 165SC Pedestrian Traffic Deck System is a liquid applied, polyurethane waterproofing deck system. The system utilizes an epoxy primer, one coat of a fast setting water catalyzed polyurethane basecoat with a rubber aggregate that can be applied at any thickness, and one or two coats of an aliphatic polyurethane topcoat.
Material Use:
Polydeck 165SC is a liquid-applied, polyurethane-based waterproofing pedestrian traffic deck system designed to protect concrete and plywood substrates. It offers high flexibility and durability against weather, chemicals, spalling, and freeze/thaw damage, while accommodating structural movements.
System Components:
· Primer: Polyprime 2180SC (for metal and general surfaces), Polyprime EBF-LV (for porous or outgassing concrete)
· Basecoat: PC-550SC (water-catalyzed polyurethane with rubber aggregate)
· Topcoat: Polyglaze 100/100SC/100C or Polyglaze AL-50/AL-50SC (aliphatic polyurethane)
Applications:
Ideal for use on balconies, patios, roof decks, sun decks, walkways, and areas over occupied space.
Application Details:
· Priming:
o Polyprime 2180SC: 1 gal/300 sq ft (3 dry mils)
o Polyprime EBF-LV (for rough/porous concrete): 1 gal/200 sq ft
· Basecoat (PC-550SC):
o Rubber finish: 4 gal/100 sq ft (58 dry mils)
o Sand finish: 3 gal/100 sq ft + 1 gal/100 sq ft second coat (total 57 dry mils)
· Aggregate Broadcast:
o Rubber granules: 10 lbs/100 sq ft
o Sand (20 mesh, Moh’s 6.5+): 20 lbs/100 sq ft
· Topcoat (Polyglaze): 1.25 gal/100 sq ft (13–14 dry mils)
· Full System Thickness: 72 dry mils (1836 microns), exclusive of aggregate
· Fast Cure Option: Polyglaze Hardener reduces cure time to 2–4 hours per coat; recoats within 8–12 hours
Special Notes:
· Not suitable for below-grade slabs, unvented metal pans, magnesite, asphalt, lightweight concrete, or pool decks.
· Concrete must be 3000 psi minimum and cured for 28 days.
· Must be applied >5°F above dew point.
· Substrate must be sound and properly sloped for drainage.
· Pot life and working time depend on ambient temperature; details in individual component TDS recommended.
· Uncured materials are moisture and heat-sensitive.
· Coverage and thickness are lab-tested on smooth substrates; mockups are advised for accurate project-specific measurements.
· Cleaning: Use urethane-grade environmentally safe solvents immediately after application.
UV Stability:
Polyglaze topcoats are aliphatic polyurethanes, which are UV stable, ensuring long-term exposure resistance.
