Final answer:
For installing crown moulding, a pneumatic or cordless finish nailer that accommodates 15 or 16-gauge nails is ideal for its precision and appropriate power.
Step-by-step explanation:
The best nailer for installing crown moulding typically would be a pneumatic or cordless finish nailer. These types of nailers offer precision and the right amount of power for attaching trim finely without splitting the wood.
A finish nailer that accommodates 15 or 16-gauge nails is an excellent choice for crown moulding projects as these nail sizes provide a good hold and are small enough to hide easily with wood filler. It's also beneficial to use a nailer with an adjustable exhaust to prevent blowing dust onto the finish of your moulding.
