Sinking the head of a finishing nail is an important step for any woodworking project. Finishing nails are a little different from regular nails since they have a small head that can easily be hidden under the surface. Whether installing trim or molding or doing furniture, it is important to learn how to sink the head of a nail without causing damage to the surface. This article will take you through every step and offer useful tips for a flawless finish
Use the Correct Finishing Nail
Use a finishing nail. Finishing nails are slimmer and more shallow; they avoid the splitting of wood. Measure the nail length as close as possible to twice the material thickness that you are going to hammer. Be cautious with too long nailing. A too-long nail could pass through to the opposite side.
For trim or molding, it is wise to use finishing nails in the size 1 inch to 2 inches in length.
Pre-drill a Pilot Hole (Optional)
For hardwoods, it is always preferred to pre-drill the pilot hole. This will give you the advantage of not allowing the wood to split as the nail is hammered in straight without causing damage to it. A smaller diameter drill bit in comparison to the diameter of the nail would do. This minimizes the chance of splitting and also the bending of the nail.
Key Take Away: Just drill to half the length of the nail for the pilot hole
Hammer the Nail
Position the nail vertically to the surface. Hold that in place and tap it lightly with a hammer, beginning with very light taps which won’t bend the nail nor leave hammer marks; keep tapping until the head of the nail is pretty much flush with the surface of the wood.
Key Tip
A small-headed hammer makes this easier to do and give you more control.
To sink the head of a finishing nail without damaging the surface, you need a nail set tool. Place the pointed end of the nail set on the nail head. Tap the nail set with a hammer until the head sinks a little below the wood surface. You want to create a small indentation without damaging surrounding wood.
Key Tip: Select a nail set size that matches the nail head.
Filling in the Hole Using Wood Putty
Step 5 will be to sink the head of the nail into the wood and fill in the hole using wood putty for a smooth finish. Press putty into the hole with a putty knife, smooth the excess using sandpaper, and let dry completely before sanding. This process makes the nail nearly invisible.
Key Tip: Choose the colour of the putty based on your wood type.
Sanding and Finishing the Surface
Once the wood putty is dry, lightly sand the area for a smooth finish. Fine-grit sandpaper should be usedto avoid damaging surrounding wood. After sanding, you can paint or stain the surface for a flawless, professional look. This final step helps the nail hole blend with the wood surface.
Key Tip: Wipe away any dust before applying paint or stain.
