Whether you are redecking an existing frame, or starting with a brand new frame, your entire frame including interior joists should be square and level within ⅛” or 3mm.
Start away from the structure and work towards it so any boards that need to be ripped lengthwise are against the home or structure.
Each board must be secured across a minimum of 2 spans. This means that each board must be secured to a minimum of three joists.
Boards that run perpendicular to the primary boards, such as feature boards or picture framing boards, require additional framing and shimming.
You must install the deck boards at a 90 degree angle to the joists. Diagonal boards are not allowed with the Step-Clip for Kebony system. If you want to install your Kebony decking at an angle, you can use the Fastenator Hidden Clip system, Pro Plug System for Kebony or face-fasten the boards using stainless steel screws.
Inline boards or butt joints require a sister joist the length of a Step-Clip strip. In most cases, this means you will need to add a sister joist that supports a full Step-Clip strip. Sharing a Step-Clip strip between two inline boards is not allowed because there isn’t adequate support for each board.
