Which type of nailer should use to hang crown moulding?

To hang crown molding, a finish nailer is the best choice, typically using 16-gauge or 18-gauge nails. The finish nailer provides enough power to securely fasten the molding while leaving minimal damage to the wood. Additionally, a brad nailer can also be used for lighter moldings, but a finish nailer is generally preferred for its stronger hold. Make sure to use the appropriate length of nails to ensure a secure installation.
