For installing baseboard shoe moulding, which nailer should be used?

Using an 18-gauge nailer for installing baseboard shoe moulding is ideal because it strikes a balance between being sturdy enough to hold the moulding securely while minimizing the risk of splitting. The 18-gauge nails provide sufficient holding power for lightweight trim work like shoe moulding, which typically has a profile that is not overly thick or heavy.

Opting for this size also means that the nail holes are smaller, which reduces the need for extensive filling and finishing work after installation, leading to a cleaner final appearance. The flexibility of the 18-gauge nailer allows for more controlled and precise placement, which is particularly important in trim applications where the visibility of the nails can affect the overall look of the project.

In contrast, larger gauge nailers, such as a 16-gauge, would be too heavy-duty for this type of work and could result in larger holes that require more finishing. A 26-gauge nailer is typically used for very delicate work or extremely lightweight trim, which may not provide enough holding power for shoe moulding. A standard finish nailer might refer to any size, but it's essential to specify the gauge, and in this context, the 18-gauge is the most suitable choice.
