Fastening Methods: AZEK Rim Joist Cover/Riser Installation Guidelines
Recommended Fasteners
• Due to the durability of AZEK Deck products, a high-quality fastener is recommended that meets the following
specications:
• Stainless Steel
• Minimum Screw Size: #7
• Face screws to be a minimum length of 1 3/4”
• Avoid using athead screws. Trim head screws typically provide a better result. As always, you should try the
fastener in a sample board before using on your deck.
• For salt water coastal applications, we suggest using the above minimum fastener requirements in 316 stainless
steel.
• Color-matched stainless steel deck screws are also available. Your AZEK Building Products dealer can assist with
more information on these products.
Storage
• Store rim joist cover in a cooler, shady area prior to installation.
• Store rim joist covers on a at solid surface.
Rim Joist Cover/Riser Attachment
• Attach rim joist cover to a solid backer wide enough to support the entire width of the rim cover. Use 2 x 12 wood
rim board or rip cut rim joist cover to t exactly.
• Use a quality exterior rated construction adhesive as shown below.
• Install three (3) screws from top to bottom with top and bottom screws positioned no more than 1/2” from the edge
as shown below. The third screw should be approximately centered in the board. Repeat this conguration every
12”. Screws at ends of boards should be no more than 1/2” from the end.
AZEK Stair Risers
• Use as a riser for stairs.
• Can also be used as a Rim Joist Cover for a 2x8
rim joist.
• See fastening guidelines for Rim Joist Covers
• 12’ lengths and 1/2” thick x 7-1/4” wide.
