Cut Nails Video
Attaching wood strips to a concrete wall is not as hard as you might think. Using a special nail, called a cut nail, make the job easier. Drive the cut nail through the lumber and into the masonry joints. The cut nail is an harder steel than regular nails. This resists bending as you drive them into the wall.
If that is not possible, drill a hole with a hammer drill through the lumber and into the concrete. Then insert two to three cut nails into the hole and pound all of them in.
If you don't have any cut nails and you are in a pinch, you are use 2 or 3 regular nails. First, drill the pilot hole with the hammer drill. Then drive in the regular nails at the same time. This will provide a strong connection from the wood to the wall.
