Installation Guide

Page 2
AZEK Deck/Rim Joist Covers should be installed using the same good building principals used to install wood or
composite decking and in accordance with the local building codes and the installation guidelines included below. AZEK
Building Products Inc. accepts no liability or responsibility for the improper installation of this product. AZEK Deck/Rim
Joist Covers may not be suitable for every application and it is the sole responsibility of the installer to be sure that AZEK
Deck/Rim Joist Covers is fit for the intended use. Since all installations are unique, it is also the installer’s responsibility
to determine specific requirements for each Deck application. AZEK Building Products recommends that all applications
be reviewed by a licensed architect, engineer or local building official before installation. If you have any questions or need
further assistance, please call AZEK Customer Service at 1-877-ASK-AZEK, [phone] or visit our website at www.

Tools Required
AZEK Deck/Rim Joist Covers can be installed with a minimum number of readily available tools. Many other tools are
available that can be used for installation. All tools should be used per applicable manufacturers’ instructions. Some
of the basic tool requirements:
• Cordless Driver • Carpenter Square
• Chalk Line • Spacing Tools
• Tape Measure • Miter Saw
• Jig Saw • Safety Glasses
Use the jigsaw to cut around obstructions such as posts. For best results a miter saw with a fine-toothed, carbide-
tipped finish trim blade (12”-60 tooth minimum) works well for cutting. For a power miter or compound power miter
saw a fine finish alternate top bevel blade is also recommended. When working with AZEK products be sure to wear
proper clothing and safety equipment. Safety glasses should be used during the entire installation process. Do not use
any cordless saws.

Routing
AZEK Deck/Rim Joist Covers should not be routed with the
exception of the start/stop boards (see page 6 step 8).
Color and Grain Patterns
Color variation is purely aesthetic and does not or will not
affect the performance of the product.
Roof Tops
In areas with unobstructed airflow such as roofs and on
grade applications, a minimum of 1” sleeper system is
required.
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 for deck re-planking (removing old deck
surface boards and installing AZEK on code-compliant
substructure), AZEK Deck Boards CANNOT be installed
on top of an existing deck.
AZEK Deck
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 nail AZEK Deck
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 cut ends of boards to ensure they
are square.
Walking Surface
AZEK deck boards need to be installed embossed side up.
Static Electricity
Static build-up is a natural occurring phenomenon that
can occur with many plastic products including PVC
Decking. It could occur with AZEK products under the right
environmental conditions.
Cantilevering
For best results, don’t cantilever over 1/2”.
