How Much Air Pressure Does A Nail Gun Need?

Do you want to perform roofing or sheathing jobs at your home? Or, are you remodeling your home and installing the sidings? You can perform all of these tasks with a nail gun with ease and perfection.

However, there’s a precondition to it. That is, you need to use the right nail gun with the right pressure for the project. It brings us to the all-important question, “How much air pressure does a nail gun need?”

When you choose the right pressure requirements for different nailers, your construction and woodworking job gets easier. It boosts your productivity and improves the finished project quality for better profit.

That’s why we decided to bring this guideline on nail gun air pressure for framing nail guns, brad nailer, finishing nailer, roofing nailer, etc., for your convenience.

Nail Gun PSI Table

The pressure of the nail gun is measured in Pressure Per Inch (PSI). The PSI level of the different nail guns such as roofing nailer, siding nailer, and framing nailer varies differently. Also, it depends on the hardness of the surface you are working with for nailing.

For instance, framing a softwood surface will require less pressure and power than a hardwood surface. Thus, you need to look at the surface hardness and the type of your nail gun to change the PSI level slightly for the best results.

The following table includes the probable standard range of the nail gun air pressure measurements:

Type of the Nail Gun Pressure Requirement
Brad Nailer 60-100PSI
Framing Nailer 70-130PSI
Finish Nailer 80-130PSI
Roofing Nailer 90-120PSI
Pin Nailers 80-100PSI
Flooring Nailer 70-100PSI
Siding Nailer 70-100PSI
Palm Nailer 50-120PSI

Nail Gun Pressure Requirements

In the table above, we have already shown the standard pressure range of the different nail guns. Now, let’s take it one step further and discuss it in detail so that you can understand the different air pressure required to work with the specific nail gun.

Brad Nailer

Brad nailers are made for intricate jobs and small woodworking projects. Woodworkers use the brad nailers for jobs where the finish doesn’t need to be pretty attractive. Instead, the focus is on achieving the right attachment using the nails.

The brad nailers use smaller nails. Thus, it doesn’t need higher pressure requirements. Instead, it can easily do the nailing job with a relatively lesser PSI range.

The required air pressure level for the brad nailers is 60PSI to 100PSI. The nails are around 1/2-inch to 2-1/2 inches long, and the gun accommodates 18-gauge nails mostly. Thanks to such smaller nails, brad nailers work easily with optimum PSI range.

Nonetheless, the actual pressure for the brad nailers will depend on the thickness and hardness of the surface. If you have a softwood surface, you may do away with 70-80PSI, but for the hardwood surface, you need to apply 100PSI or slightly more pressure to penetrate the surface with the nail properly.

However, before you begin the main project, pick your desired diameter and length of the nails and check the required pressure for brad nailers. It will yield the best results.

Framing nailer

Framing nail guns are among the heaviest and largest nail guns you will find for different projects. These nailers are gettable in various designs and perform various woodworking jobs. They use mostly collated and coil types of nails.

However, the framing nailer PSI requirements depend on the size of the nailer but not on the nail type you will use. The larger the nail, the more pressure you will need to push it through the surface. Framing nailers use mostly 2-inch to 3.5-inch nails.

The pressure range will differ from 70-130PSI, mostly with 2-inch nails needing 70-75PSI and the 3.5-inch nails requiring 120PSI to 130PSI. Also, the hardness of the surface may affect the required PSI range slightly.

Framing nailers need more pressure as it uses the largest nails. Thus, you need to work with increased caution when working with framing nailers as enhanced pressure may damage the nails and the surface if not handled properly.

Finish Nailer

Finish nailers are used for building cabinets, installing baseboards, hardwood floors, and woodworking joinery mostly. Since it is used for intricate points, it also uses nails similar to brad nailers. However, the final appearance is important with finish nailers, unlike the brad nailers.

Hence, selecting the right PSI range is even more important for finishing nailers. This nailer use 3/4-inch to 2-1/2-inch nails, which are similar to the brad nailers. Hence, the pressure requirements of finish nailers are close to brad nailers.

The standard PSI range is from 80PSI to 130PSI mostly. When using the finish nailers in various projects, check out the required pressure level depending on the nail size and surface hardness. A softer surface will need less pressure than the hardwood ones.

Also, ensure that you push the nail safely without damaging the surface. The hole should be easily filled with wood putty.

Roofing Nailer

The fourth on our list is the roofing nailer. These nailers use coil nails through a rounded housing for the best nailing jobs.

It releases from the gun much like a belt. So, you face any jamming of the nails through the gun and accomplish the job with ease. The roofing nailer usually shoots ¾ inches to 1-3/4 inches nails, mostly for various projects.

Also, the nails are made of galvanized materials and so need more pressure for the nailing jobs. On top of it, roofing nailers are users mostly on hard surfaces such as asphalt. Therefore, the pressure requirement of the roofing nailer is slightly higher at 90PSI to 120PSI.

Pin Nailer

Pin nailers are designed to pierce through the hardest surface at ease without any heads on the nail. Also, the nails used by pin nailers are called pins as well. The required pressure for the pin nailers varies from 80PSI to 100PSI mostly.

You can use a light to a medium-duty air compressor with the pin nailers to generate the required pressure with ease. Also, the pin nailers shoot mostly 23-gauge pins. So, once you set the pin nailer at the right pressure level, you may work with ease.

Flooring Nailer

Flooring nailers are used mostly for attaching floor and basement portions. The size of the nail depends on the thickness of the surface you will nail through for attachments. The pneumatic flooring nailer uses 70PSI to 100PSi depending on the hardness of the floor wood.

Usually, thicker floors will need larger 1-1/2 inches nails, so it will need the highest pressure to penetrate the nails. Next, the softer wood floor may be easily penetrated at 75PSI. Thus, we suggest you check the hardness of the floor wood and choose the right pressure for the flooring nailer accordingly to yield the best nailing results.

Siding Nailer

A siding nailer, as the name suggests, is used for installing siding of the house. It is used to attach thinner pieces of a metal frame with a wooden frame around the sides of your home.

It uses shorter nails. The nail size differs from 1-1/4 inches to 2-1/1 inches, mostly compared to the larger nails used by a framing nailer. The pressure requirement varies from 70PSI to 100PSI, with the larger nails needing a higher pressure level.

You can use a medium-duty air compressor for the siding nailers to get the required pressure and work with greater satisfaction.

Palm Nailer

Palm nailers are the smallest nail gun used to drive nails through the tightest spots with ease. Although it fits easily into one’s palm, its pneumatic construction means it still needs the right amount of pressure to work on accurately.

The palm nailers drive non-collated nails individually. It uses smaller nails and serves general purposes. Thus, the nailer also requires the least pressure. You can drive the non-collated nails easily at 50-90PSI for a perfect woodworking job.

However, some larger palm nailers might need up to 120PSI requirements for the 3-1/2 inches long nails.

Final Words

You should now have a clear idea of how much air pressure does a nail gun needs. We have discussed the pressure requirements of the eight common pneumatic nailers concerning their nail size. Thus, match the nail size of the different nail guns with the right pressure for the best nailing jobs.

The best way to choose the right PSI level is to test a couple of nails with different pressure. When you find the right pressure to drive in the nail properly, your nail guns, jobs will become easy and fun.
