post sleeves are designed to fit over dimensional 3⁄x3⁄ posts. If the 3⁄x3⁄ posts you are using are outside of standard, trimming or shimming of the 3⁄x3⁄ edges
may be required. Check fit of the 3⁄x3⁄ post into the post sleeve prior to attaching it to your deck structure and make any changes to the 3⁄x3⁄ if needed.

INSTALLING POSTS TO DECK SUBSTRUCTURE:
Step 1: Determine the location and install the 3⁄x3⁄ treated posts to the substructure. The maximum
post spacing is 6' to the center of each post. Do not notch 3⁄x3⁄ railing posts.
Step 2: Use blocking that is the same size and dimension as the joist members to reinforce the side of the
3⁄x3⁄ post opposite the rim joist.
Step 3: Use three 3" quality deck screws for attaching each end of blocking to joist.
Step 4: Secure pre-drilled 3⁄x3⁄ treated post to the rim joist and reinforcement blocking using two 6" lag
screws (minimum spacing of 5¼" apart.) Countersink the lag screws if using UltraDeck
®
cladding.
*For deck designs including railing
• Use Masterforce
®
composite decking blade (SKU 252-6662 7⁄" or SKU 252-6663 10") for any cutting.
• If the decking substructure is freshly treated, allow adequate dry time to reduce joist movement.
• Decking substructure should be built with a slight angle so that water runs off the decking; a
recommended slope is ½" drop every 10', away from the building, along the orientation of the decking.
• Ensure that all joists are crowned correctly and that all joists are level across the top as UltraDeck
®
will conform to the
surface contour of the substructure.
• Proper joist spacing is required for proper installation. Joist spacing should never exceed 12" on center.
• For best results, install wood blocking between each joist, placed every 4'-6' within the structure. This will help reduce
movement or twisting of the joists. Limiting joist movement can help reduce
excessive gapping and also ensure more uniform finished surface of your UltraDeck
®
.
• Using joist tape can lengthen the life of the decking substructure.
• Radius edge profiles should be used for stair treads & deck boarder applications.
Once you decide which way the deck boards will run,
determine the span between the joists. Always adjust the joist
span to accommodate the deck pattern and stairs. Be sure the
foundation is sound, level, and use a minimum of two fasteners
for attachment of deck boards to each joist. Be sure to check
local codes for additional requirements and information.
Additional framing will be required for all butt joints. See nailer
board information in Plank & End Gapping.
Check local building codes before starting any project!
