Tools Required: Variable speed cordless drill (Do not use impact driver), chalk line, tape measure, jig saw, carpenter square, spacing tools, miter saw, safety glasses TimberTech® AZEK® Decking: AZEK® does not recommend the use of rubber or vinyl products (welcome mats, planters, etc.) on deck boards. A reaction can occur that causes discoloration of the decking under the rubber/vinyl product. This is a common caution for polymer decking products. DO NOT use nails to fasten AZEK® Decking or Fascia boards. Cutting or drilling metal should not be done on AZEK® Deck boards as metal shavings may be come hot and embed themselves into the deck boards. Always be sure to check and cut the factory ends of boards to ensure they are square.
Walking Surface: AZEK® deck boards need to be installed embossed side up only.
Static Electricity: The buildup or generation of static electricity is a naturally occurring phenomenon in many plastic based products such as carpeting, upholstery, and clothing, and can occur on alternative decking under certain environmental conditions. Static electricity is not a defect and can occur naturally.
Cantilevering: For best results, do not cantilever 1/2” beyond the edge of the Fascia or deck framing. Routing: AZEK® Deck/ Fascia should not be routed on the edges, ends, or sides with the exception of the start/stop boards as shown in this guide (under CONCEALoc section).
Color and Grain Patterns: AZEK® Deck is designed to mimic the look of real wood, and like real wood, there will be a slight difference in color and grain pattern from board to board. This is intentional and part of the manufacturing process, giving AZEK® Deck the most realistic and wood-like appearance possible. This variation is purely aesthetic and does not or will not affect the performance of the product. When working with multiple units of decking, consider pulling boards randomly to mix rather than completing one unit at a time. It is always a good practice to layout deck boards in different lighting conditions/angles before final fastening.
Color and Temperature: Although AZEK® Deck products are cooler to the touch than many other deck board products in similar colors, all decking products will get hot in the sun. Additionally, the darker the decking color, the hotter it will feel
Air Flow Considerations: In areas with obstructed airflow such as roofs, water management systems, skirting and on-grade applications, a minimum of 1-1/2” clearance should be provided.
Note: AZEK® Deck is NOT intended for use as columns, support posts, beams, joist, stringers, guard railing or other primary load-bearing members. AZEK® must be supported by a code compliant substructure. While AZEK® products are great deck re-planking (removing old deck surface boards and installing AZEK® on code-compliant substructure), AZEK® Deck Boards SHOULD NEVER be installed on top of an existing deck.
Calculating Material Requirements: To determine how much TimberTech® decking material you will need, start by calculating the square footage of your deck surface by multiplying length by width. Once you know this number, divide it by the numbers provided below for 12’ boards, 16’ boards and 20’ boards. Once you know the square footage number, divide it by 5.5 for 12’ boards, 7.3 for 16’ boards and 9.1 for 20’ boards. When calculating the amount of decking you will need, it is recommended that you add roughly 10% to the total for a scrap factor.
Example: Length x Width = Total Square Footage Square Footage ÷ by 5.5 (12’), 7.3 (16’) or 9.1 (20’) = Boards Needed (Round the number up) Boards Needed + 10% (Scrap Factor) = Final Number of Boards Needed (Round the number up)
