On The Saturday Early Show, Rent-A-Husband.com's Kaile Warren gave a quick do-it-yourself solution to add perimeter seating to your deck.
Adding a perimeter bench to your deck is as simple as building the supports needed for the seating, according to Warren. The seating supports are comprised of two pieces of lumber, a 2x4-inch and a 2x12-inch.
The 2x12-inch lumber should be cut to a standard 18-inch. The height of the 2x4-inch will be determined by the height of your deck's railing.
Both the 2x4-inch and 2x12-inch boards should have ten-degree angles on each end, cut parallel to one another.
The 2x4-inch will be the back of the support, which will be anchored to the rail system. The 2x12-inch will be anchored to the deck. The 2x12-inch will also support the seating, which should be attached once all the supports are in place. Both will ensure a deck with more support.
Another cut to the 2x12-inch involves removing the bottom corner (so you don't bang your feet on the supports). To do this, simply mark four inches from the bottom corner and draw a line from there to the top corner on the same side of the 2x12-inch (be sure you are cutting the outward bottom corner, which is opposite the side of that which will align with the 2x4-inch).
Once the 2x4-inch and 2x12-inch have been cut, attach the two boards by first placing a bead of construction adhesive between the edges and then by hammering wood two joiners to each side of the support.
Once the support is complete, attach it to the handrail post using screws. The holes should be pre-drilled. If you cannot screw the support into a post, then attach the support beneath the decks rail system. Do this by using two deck screws from the top. The bottom of the support can be attached by screws from the deck bottom or by putting two screws at an angle from each side of the support bottom into the decking material.
The supports should be spaced at no more than four feet along the deck railing.
The final step is to install the seating board over the seat supports, anchoring them with decking screws.
The seating should consist of a back and seat. Composite decking is ideal because it does not splinter and can be stained or painted.
That's it. The project, Warren says, would take the typical homeowner an afternoon to accomplish.
