Walk Deck Tear-Off and Multi-Layer Waterproof Coating Replacement in Scottsdale, AZ

A homeowner in Scottsdale, Arizona chose SUNVEK for an out-of-pocket walk deck replacement after the existing deck surface showed signs of wear and needed a refreshed waterproofing system. This was a retail project with no insurance claim or lender involvement, focused on removing the old deck surface, installing new wood where needed, and rebuilding the walk deck with a multi-layer coating system.

The elevated walk deck served as an outdoor living space with surrounding railings, wall transitions, and scenic desert views. The project covered approximately 50 square feet and included a complete tear-off, substrate preparation, new wood installation, flashing, and a layered system of Poly Prime, PC 260 coatings, deck sand, and Poly Glaze finish coats — restoring durability, surface protection, and confidence in the outdoor space.

Problem: Aging Walk Deck Surface and Waterproofing Concerns

The existing walk deck needed more than a surface touch-up. Worn perimeter transitions and areas where the deck edge and wall details required attention had to be addressed before a new waterproofing system could be installed.

Because the deck was elevated and surrounded by walls, railings, lighting, and access points, the work required a careful tear-off and clean installation. The homeowner needed a solution that would protect the structure while preserving the look and usability of the outdoor space.

Solution: Walk Deck Tear-Off With Multi-Layer Waterproof Coating

SUNVEK replaced the walk deck system by tearing off the existing surface, disposing of project debris, and preparing the substrate for a new waterproof assembly. New deck wood was installed where required, secured with screws and glue, and flashing was added at vulnerable transitions. The crew then applied Poly Prime to the new wood surface to prepare it for coating.

From there, the team applied a PC 260 base coat followed by a PC 260 sand coat, broadcast deck sand for texture and surface grip, then finished with a Poly Glaze base coat and Poly Glaze topcoat to create the final protective walking surface. The layered system provides both waterproofing and a durable, textured finish designed for everyday use on an elevated outdoor deck.

Result: Restored Outdoor Living Space With Better Surface Protection

The completed walk deck replacement gave the Scottsdale home a refreshed waterproof surface with a cleaner, more durable finish. The new coating system helps protect the elevated deck from moisture exposure while creating a more usable outdoor area with improved texture and grip.

For the homeowner, the result was both functional and reassuring. Rather than a temporary patch, the deck was restored with a professional multi-layer system — tear-off, new wood, flashing, primer, coatings, and finish — all backed by a 2-year warranty. The project delivered renewed confidence, better protection, and peace of mind when enjoying the outdoor space.
