Collection: Products for the Westcoat ALX Pro Standard Finish Waterproof Deck System

Build a stronger waterproof walking surface on plywood balconies and roof decks with the Westcoat ALX Pro Standard Finish System. This reinforced plywood deck waterproofing system adds a Fiberlath-reinforced membrane for extra crack resistance and flexibility on decks with spans of ten feet or more, under a textured finish with the look and feel of concrete. It can also be stapled through most old deck systems to rehabilitate problem surfaces.

It starts with the same base as ALX Standard, then adds WP-47H Fiberlath HD set in WP-90 Waterproofing Resin mixed with TC-1 Basecoat Cement, followed by the slurry and texture coats and SC-10 Acrylic Topcoat for a tough, UV-resistant color coat. Find the products for the ALX Pro Standard Finish System, along with optional components for full-deck membrane coverage, alternative texture finishes, and added slip resistance, below.
