Collection: Products for the Westcoat ALX Standard Waterproof Deck System

Give plywood balconies, walkways, and roof decks a waterproof walking surface with the look and feel of concrete using the Westcoat ALX Standard Finish System. This lath-reinforced plywood deck waterproofing system hides plywood seams under a skid-resistant textured finish and can be stapled through most old deck systems to rehabilitate problem surfaces.

The system pairs TC-1 Basecoat Cement and WP-81 Acrylic Polymer Cement Modifier with 6" WP-40X Sheet Membrane, WP-53 Hybrid Sealant, and WP-30 Glass Lath, then finishes with SC-10 Acrylic Topcoat for a tough, UV-resistant color coat. Find the products for the ALX Standard Finish System, along with optional components for full-deck membrane coverage and added slip resistance, below.
