The Comprehensive Guide to Deck Installation includes step-by-step instructions for installing a deck. It provides information on the dimensions of the lumber, the post-to-beam connection, staggered spacing of decking boards, and the installation of Ledger boards. This guide also includes helpful tips for installing railings and handrails. Listed below are some of the essential topics covered.
Dimensions of lumber for decking
If you’re building a deck, one of the first questions you may have is what dimensions of lumber you need to buy. Often people plan their material list based on “nominal dimensions,” which are dimensions of unfinished or rough lumber that haven’t been surfaced. These dimensions are generally a good rule of thumb for decking projects. However, when deciding how much decking you need, remember that the deck will be visible from all sides, so choose lumber accordingly.
There are several dimensions for lumber, but you can usually find them on the label. Standard deck posts are usually 4x4s or 6x6s. A 6-by-6 post should be used for decking above 6 feet. Pressure-treated lumber is typically made from fir or pine and is heat resistant. For warm climates, pressure-treated lumber will provide excellent protection from insects and mildew. Pressure-treated lumber may be less expensive than wood from other species but check for loose knots.
Regarding deck installation Rocklin CA, post-to-beam connections can be tricky. Beams at corners are particularly problematic, as the angled sides of the deck will force the posts to bend. The best way to solve this problem is to install a butt joint between the seats and the beams. It is also best to use fasteners with countersunk heads to prevent them from sticking out.
There are two basic types of post-to-beam connections. The first type, called a splice, is where a notch is cut in the post’s outer edge. The notch needs to be deep enough to support the entire beam width yet shallow enough to retain enough wood to hold the beam securely. Once the notch is cut, multiple bolts are inserted through the beam and the post.
Staggered spacing of decking boards
For stability, staggered spacing of decking boards is necessary when using traditional wood decking. This spacing is crucial because wood does not expand equally in all directions. For example, a 16-foot pine board could shrink an inch and a quarter, depending on the wood used.
In addition to wood, other materials like redwood, cedar, and PVC can be spaced similarly to cedar. The spacing is 1/8″ and can be achieved using eight-d nails as spacers. Afterward, the deck boards should be pushed flush against the spacers and secured using a fastener. This will prevent any gaps or voids that might occur later during the installation process.
Ledger board installation
Before installing ledger boards, it is essential to know what they are made of. They are usually made of 2×8 pressure-treated No.2 grade lumber or comparable material. You must also install flashings to prevent water contact. Several structural screw manufacturers have created screws specifically for ledger installation. Some are designed for stud-to-stud installation, while others are designed for use with mudsills.
Typically, metal flashing is installed on the top edge of the ledger. This metal flashing should extend well below the edge of the board. To establish a self-adhesive membrane, you must remove the entire row of siding above the ledger. When you’ve finished, you can attach the self-adhesive membrane.
The International Residential Code specifies using two types of fasteners for ledger boards. Listed are 1/2-inch-diameter hot-dip-galvanized hexhead machine bolts and lag screws. Do not use carriage bolts, which may not be allowed in your local jurisdiction. The code also provides a table illustrating how to space these fasteners.
