Attaching Wood to Concrete

A key tip is to use the best tool for each method. If you are coping with concrete and masonry, you're obviously addressing very unlikely material. Woodworking hammers are extremely light and steel drill bits too soft. The concrete is also brittle. Hard sharp chips will likely fly out as you work with it, so always wear safety goggles to safeguard the eyes.
Nails. Nailing wood straight away to concrete is probably the simplest, quickest and cheapest method. Unfortunately, once driven, these nails may jar loose from the few hammer blows aside of the board. So, they are better for temporary fastening.
You'll usually find 2 types of special nails with the shop, cut nails and hardened concrete nails. Drive nails with a 2- to 4-lb. hammer. Actually, it is quite hard to drive nails into cured (hardened) concrete, even with a 4-lb. hammer. They perform best in concrete that's only cured for a few days.
Nails are extremely effective in mortar joints, however. Mortar is softer than either the concrete block or brick, but it holds nails fairly well. For best results, drive them right on the joint edge. And here's a professional tip: for improved holding power, operate a bead of glue over the backside of this wood before nailing up.
Predrilled Fasteners. There's a class of fasteners that may be driven to a predrilled hole. These but not only fasten wood to concrete, but will fasten anything else to concrete also.
They install easily, simply drill throughout the wood and into your concrete and drive the fastener.
Drilling the hole could be the only difficult part. Employ a carbide tip bit. Because holes are relatively small, your standard 1/4-inch or 3/8 inch power drill are able to do a sufficient job, although each hole will take several minutes to bore. A hammer drill, however, will drill your hole within seconds. A hammer drill is dear, but they could be rented. If you have a great deal of holes to drill, they'll save a long time.
It's wise to glue your wood towards concrete or masonry on this system in addition, specifically when using screws. Once screws are jarred loose, they may not retighten.
Expansion Fasteners. These fasteners are quite obvious, effective which enables it to have a heavy load. They may be retightened if and when they are jarred loose.
