What Is Pli-Dek?
The Pli-Dek Standard System is a multi-layer waterproofing and deck coating system that consists of a galvanized metal lath, polymer cement base coat and intermediate coat followed by a wide selection of durable finishes. It creates a fully walkable, slip-resistant, and fire-rated surface that is ideal for both residential and commercial projects. What is great about the Pli Dek waterproof deck coating is that it already carries a One-Hour and Class A Fire Rating. This means you don’t need to add One-Hour Fire Rated assemblies to your wooden deck, eliminating additional framing expenses.
Pli-Dek is known for:
- Class A Fire Rating
- Long-Lasting Durability with 6,000 psi cement strength
- Meets ADA slip-resistance and ICC requirements
- UV and Weather Resistance
- Code-Approved for California Fire Zones
Benefits of Pli-Dek for Your Deck or Patio
Safety and Fire Resistance
Wood decks can be a fire risk—but not with Pli-Dek. This system is Class A fire-rated and built to protect your home or building. It’s been tested extensively under ASTM fire standards, giving you peace of mind in high-risk fire zones.
Durability for Heavy Foot Traffic
From rooftop patios to high-use walkways and balconies, this system handles heavy foot traffic with ease. The surface is slip-resistant and designed for high-use areas in both residential and multi-family or commercial properties.
Low Maintenance
Tired of staining or resealing your wood deck every year? With Pli-Dek, you won’t have to. This system makes your wood easy to care for, eliminating the typical maintenance that comes with traditional decking materials.
Waterproof and UV Resistant
Pli-Dek shields your deck from more than just water. Its UV-resistant coating protects against harsh sun exposure, keeping your deck from cracking, fading, or weakening over time.
Cost-Effective & Long-Lasting
Forget high-maintenance costs and expensive lumber. Pli-Dek adds only about 3/16″ thickness to the deck surface, allowing you to save money on materials while still getting a premium, high-performance finish.
Where Can Pli-Dek Be Installed?
Pli-Dek can be installed on decks, rooftop patios, walkways, breezeways, balconies, and outdoor corridors, offering a durable and weather-resistant finish for various outdoor surfaces.
Whether it’s a multi-family building, single-family home, HOA property, or commercial walkway—we have you covered.
