Do I need a compressor for a nail gun?

Only for pneumatic (air-powered) nailers. Battery-powered cordless nailers have become excellent alternatives that eliminate the need for a compressor, hose, and fittings. Cordless nailers cost more upfront but offer portability and convenience. For home DIY use, a cordless brad or finish nailer is often the best investment.

What is the difference between a finish nailer and a brad nailer?

A finish nailer drives 15 or 16-gauge nails that are thicker and provide more holding power for heavy trim, baseboards, and door casings. A brad nailer drives thinner 18-gauge nails suited for lighter trim, molding, and panel attachment. Brad nails leave smaller holes but hold less. Choose finish nailers for structural trim and brad nailers for decorative molding.

What nail angle do I need for my framing nailer?

Framing nailers come in 21-degree, 28-degree, and 30/34-degree magazine angles. The angle primarily affects access in tight spaces — steeper angles (30/34-degree) reach into corners better. The nails themselves perform identically regardless of angle. Buy nails that match your specific nailer angle. You cannot interchange nails between different angle nailers.

Size Selection Guide

Framing nailers: 21 or 30/34-degree, driving 2 to 3-1/2 inch nails (16d and 8d common). 15-gauge finish nailers: 1-1/4 to 2-1/2 inch nails for heavy trim, door frames, and baseboards. 16-gauge finish nailers: 1 to 2-1/2 inch nails for general trim and cabinet face frames. 18-gauge brad nailers: 5/8 to 2 inch nails for light trim, molding, and panel goods. 23-gauge pin nailers: 1/2 to 1 inch pins for delicate trim where no visible hole is desired.

Installation Tips

Always test fire into scrap wood to set the depth adjustment correctly. Maintain proper air pressure (70-120 PSI for most pneumatic nailers). Hold the nailer firmly and perpendicular to the surface for straight driving. For trim work, set nails slightly below the surface and fill with putty. Use sequential trigger mode (not bump fire) for precise finish work. Keep the gun clean and lubricated per the manufacturer's schedule.

Common Mistakes to Avoid

Using a framing nailer for finish trim (nails are too large and leave ugly holes). Driving nails at angles unintentionally due to improper contact with the surface. Not adjusting depth setting causing nails to sit proud or drive too deep. Using the wrong nail strip angle for your nailer model. Ignoring safety — always treat a nail gun like a loaded weapon and never point at anyone.

Budget Guide

Pneumatic brad nailers start at $50-80. Pneumatic finish nailers cost $100-200. Pneumatic framing nailers run $150-300. Cordless battery nailers cost $200-400 for brad/finish and $300-500 for framing. A basic compressor for pneumatic nailers costs $100-200. Nail strips cost $30-60 per box of 2,500-5,000 depending on gauge and finish. Cordless eliminates the compressor and hose cost.
