The AZEK Trim & Moulding Installation Guide (2025 PDF) provides complete instructions for installing AZEK’s premium cellular PVC trim and moulding products. This guide covers everything from cutting, drilling, and routing to fastening, expansion and contraction, painting, gluing, and specialty profiles such as water table, universal skirt board, integrated drip edge, rabbeted cornerboard, and column wraps.
AZEK Trim and Moulding are designed to mimic the workability of wood while delivering long-term durability and minimal maintenance. The guide outlines proper storage and handling methods, recommended saw blades, safe drilling techniques, and best practices for routing clean, crisp edges. Installers will find detailed information on selecting the right fasteners—such as stainless steel or hot-dipped galvanized screws—and placing fasteners within appropriate distances from joints and edges.
Expansion and contraction guidelines help ensure long-term stability, with recommendations for gluing joints using AZEK® Cellular PVC Cement, leaving appropriate spacing at ends, and avoiding dark paint colors unless using approved vinyl-safe coatings. The painting section also includes Light Reflective Value (LRV) requirements and recommendations for both Premium Trim and PaintPro® Trim products.
Specialty installation sections include step-by-step instructions for water table profiles, universal skirt board interfaces, integrated drip edges, and rabbeted cornerboards. The guide also provides clear spanning guidelines for soffits, fascias, and beadboard ceilings, including framing requirements, adhesive recommendations, and maximum allowable spans for both 1/2″ and 5/8″ beadboard.
A substantial portion is dedicated to the AZEK Column Wrap system, offering instructions for cutting, assembling, applying adhesive, folding around posts, fastening, easing edges, and ensuring plumb installation with shims. These pages also address railing-related blocking, safety precautions, and proper adhesive use.
The guide concludes with care and cleaning recommendations—such as safe power-washing settings, approved cleaners, and maintenance practices that help keep AZEK surfaces looking sharp.
