You will need hammer-set concrete fasteners to connect the wood and concrete, which you can get online or from most home improvement stores.
Take all necessary safety precautions while using a drill, and put on safety goggles and professional-grade earmuffs beforehand. In a pinch, you can also use a syringe blower to remove the dust.
Unlike the concrete, where you only have to drill 1⁄4 inch (0. 64 cm) deeper than the fastener’s length, you should drill completely through the wood.
Although 1 inch (2. 5 cm) of concrete penetration is the minimum, deeper penetration will result in a stronger hold. The longer your screws are, the tighter they will connect the wood and concrete. Concrete screws are the newest method of fastening wood to concrete and generally the most popular because they are easy to remove. [4] X Research source
Mark the holes in the concrete and wood using a permanent marker first to make sure your holes are precise. Blow the residual dust out of the concrete hole using a vacuum or syringe blower.
You will know that you have used enough copper wire if the screw fits tightly into the hole and the connection between the wood and concrete is not loose or wobbly. Thread extra copper wire through the hole if it’s too large for the screw. [8] X Research source
Mortar nails are generally the cheapest attachment option for wood and concrete.
Make sure the marked area you choose for the concrete object is in the mortar, not the concrete itself.
Put on safety goggles before hammering the nail into the wood and mortar. [12] X Research source
