Final answer:
The proper nail to use for installing interior wood moulding is a finish nail, which offers a discreet appearance. An old carpenter's trick is to use pliers to grip the nail, preventing bending by reducing vibration and bending force.
Step-by-step explanation:
To install interior wood moulding, the appropriate type of nail would generally be a finish nail, which is designed to be small and less noticeable when installed. These nails have a smaller head and are often used in finish carpentry to provide a clean look.
Regarding the carpenter's trick, gripping the center of the nail with pliers while hammering it into hard materials can prevent the nail from bending.
This method works because the pliers provide extra support and reduce the vibration and bending force that can occur when the hammer strikes the nail.
When installing interior wood moulding, it is recommended to use finishing nails. Finishing nails are slender and have small heads, which allow them to be easily countersunk and concealed. They are typically made of steel or stainless steel, making them strong and resistant to corrosion.
