Westcoat

Waterproofing never looked better.

Westcoat is a high-performance waterproofing and coating system commonly used for decking, walkways, balconies, and rooftop surfaces. Designed for both residential and commercial applications, it provides a durable, slip-resistant, and weatherproof membrane that protects surfaces from water intrusion and damage.

Westcoat systems are known for their strong waterproofing capabilities, with multiple layers that seal and protect even in heavy rain or high-moisture environments — making them ideal for long-term surface protection.

Why Westcoat?

Superior Waterproofing

Westcoat offers excellent protection against moisture intrusion, making it ideal for decks and balconies exposed to the elements.

Durable & Long-Lasting

Built with a reinforced lath and polymer-modified cement, it resists cracking, wear, and heavy foot traffic over time.

Attractive Finish Options

Available in various textures and colors, Westcoat enhances the appearance of outdoor surfaces while maintaining a clean, professional look.

Code-Compliant & Fire-Rated

Westcoat meets building code standards, including Class A and one-hour fire ratings, ensuring safety and compliance for both residential and commercial projects.
