Only use PATs on concrete that leaves a well-defined impression from the center punch or nail. If the nail sticks in, the concrete is too soft, if the surface flakes or cracks, it’s too brittle, and if it blunts or bends the nail, it’s too hard. If it leaves a well-defined impression, it’s good to go. Test the concrete’s hardness using a center punch or finishing nail. Silver cased cartridges commonly require a different PAT due to increased compression power silver brown tips have a velocity of 935ft/s, green tips 1,025ft/s, and yellow 1,115ft/s. Don’t use brass and silver color casings interchangeably. Typically, a brass-colored casing with a brown (385ft/s) colored tip, green (490ft/s) tip or yellow (575ft/s) tip is used. The color-load velocity differs depending on the concrete’s hardness. The cartridges come in brass or silver-colored casings with color-coded tips identifying the load velocities. The resulting explosion produces gasses that generate the power to drive a piston that hammers the nail. The small explosive is activated by a firing pin striking the primer charge, which ignites the powder charge. The PAT’s drive power is provided by a specially loaded. When fastening wood to concrete in damp areas such as basements, use a foam or plastic moisture barrier to prevent mold and mildew growth, or wood rot. The fasteners are often proprietary to the tool, but typically are concrete nails with a metal washer or plastic sleeve that prevents the nail head from penetrating into or through the wood. There are different powder-actuated tools (PAT) on the market for purchase, or they can be rented. Nailing wood to concrete using powder-actuated fasteners is a quick and easy, albeit noisy, process. Nailing Wood to Concrete With Powder Actuated Fasteners Attaching wood to exterior concrete surfaces, however, typically requires a sill gasket or moisture barrier to prevent moisture damage to the wood. It’s also important to note that moisture can interfere with the bonding of some adhesives. They also often have a washer or ring to prevent them from being driven through the board.Ĭoncrete, even with a moisture barrier underneath it, can still wick moisture, so wood placed on concrete that is susceptible to moisture issues should have a moisture barrier for protection. Powder-actuated tools only require about 5lbs of force to hold and drive their nail into the concrete. Both cut and concrete nails require greater hammer force to drive into concrete. Concrete nails may look like normal nails, but are made of high-carbon hardened steel and have striated shafts for better grip in the concrete. A lot more steps and mess.Ĭut nails have a tapered flat shaft and square point. Holes then need to be aligned and drilled into the wood before washers and nuts can secure them to the concrete. Some anchors are self-expanding, some require plastic or lead shields, and others some kind of adhesive to secure them in the hole. The number of holes and added steps means more time to do the job.Īnchor bolts are either placed into the concrete as it sets, or set into holes drilled into hardened concrete. Some require anchors inserted into the concrete, and others bite and grip the edges of the hole. There are a variety of different screw-down fasteners, but all require a predrilled hole. Wood can be attached directly to interior concrete using screws, screws with anchors, anchor bolts, nails, or adhesives.
