You’ll need a drill, a drill/driver, a jigsaw, a tape measure, and some string. A precision miter-box saw will help you cut crisp miter joists for the picture frame corners. The tools needed to install a picture frame are no different than what you’d use to secure all the other decking boards. The main decking boards build off the picture frame and people will notice if the spacing of the decking is not consistent. It’s imperative you take the time to ensure the picture frame boards that are running parallel with the main decking boards are straight. In reality, the picture-frame border is not much harder to install than the regular decking boards. Additional Considerations When Installing Picture Frame Deckingīe sure to consider how your rail system will be attached and how your rail posts will intersect with surrounding decking. This subtle detail can do a lot to improve the overall appearance of your deck. This allows water to drain off the board’s edge. Some deck builders install the trim board over the edge of the rim joist by about an inch in order to tuck the fascia board underneath. How Much Overhang Should a Picture Frame Deck Have? When you countersink the screws using a special driver, the head of the screw is down about ¼ inch below the surface allowing the plug to be tapped into place so the screw is hidden. High-quality composite decking often has special screws with plugs made from the actual decking. Refer to the installation instructions for the screws to use, spacing, and the plugs to use to hide these screws.įace-fastened decking requires screws that penetrate the face of the board. The outer board usually has to be face fastened. Securing the picture frame boards is simple. This is an often-overlooked issue when you start to ponder how to picture frame a deck. The deck picture frame boards can’t be tilted one way or the other because the outer rim joists are not flush with the joists or the blocking in parallel joists is not flush with the top of the other joists. Picture framing a deck requires a good amount of attention to detail so the picture frame boards are in the exact same plane as the main decking boards. Minimizing the contact area between the decking and the support is also important. Where short pieces are needed to complete the deck picture frame, an additional support should be installed between the standard spacing. Generally, no composite board should be supported on less than three joists below.
In this case, we needed to cut down the last 2 deck boards in the field to prevent the last board being only 3/4" wide. Notice the 45 degree miter cut in the corner. You may choose to continue the picture frame decking along the house wall. Step 5: Continue the Frame Along the House Wall Wood picture frame decking can be notched flush with the post. Leave a 1/8" - 1/4" gap for a picture frame with composite decking to allow for thermal expansion. Notch the picture frame border around rail posts. In this case, it is 2-1/4" because of the skirting and fascia boards that will be installed outside the frame below. Install the picture frame border with the desired overhang. Step 3: Run the Border Around an Angled Corner Install 2x4 material on top of the blocking around the perimeter of the deck for a fastening surface for the picture frame decking and to end fasten the field decking boards. Step 2: Prepare the Picture Frame for the Border You may be able to use scrap material for blocking. Install blocking 1-1/2" below the top of the frame along the sides of the deck at least 16" on center.
How to Build a Picture Frame Deck Step 1: Install Support for the Decking Border When installing these, there are a few common installation practices to keep in mind.
