16 Or 18 Gauge Nailer For Baseboard?

By Matt Hagens / ,

Interior trim work signals you are nearing the end of the carpentry work for that reno job or room addition in your home.  It is the “home” stretch if you will.  Window and door trim, maybe some crown moulding, maybe wainscoting, and baseboard are the tasks.

Depending on the trim you have chosen, you might be working with fine or delicate trim or something more sturdy and substantial.  Each will have their own needs when it comes to the attachment.

A more fine or delicate trim doesn’t need a 16-penny nail to hold it in place, and you’d split it anyway; the more substantial trim or wainscoting will require something more than a staple or small brad to hold it in place.

You get the picture.

Key Points:

  • The right tool for the right job:  For thinner or more delicate trim, including baseboard, choose the 18-gauge nailer, also referred to as a brad nailer; for hardwoods and more dense materials where strength is required, opt for the 16-gauge nailer, also referred to as a finish nailer.
  • A 16-gauge nailer is heavier, has more power, and is more expensive than an 18-gauge nailer.
  • The 16-gauge nails have larger heads and will leave larger holes to fill, while the 18-gauge nails have smaller heads and are easier to fill and smooth over.

Today we are considering baseboard.  Nailers make the job easy and quick, whether you are using a pneumatic nailer or a cordless nailer.  The major decision comes with the nail you will use (the nail the baseboard will need to stay in place), and thus the nailer.  

We’ve got a job coming up as we renovate a room damaged by a rain and hail storm.  A tree fell and punched a hole in the roof, everything got wet, and when we demo’d the roof, we found damage caused by a bad installation of flashing.

The roof has been rebuilt, new walls rebuilt, new ceiling installed, and new sheetrock hung all around.  We’re at the interior trim stage now, including baseboard installation. So, the timing is right for an article on which gauge nailer to use for that install.

What Is Baseboard Trim?

Baseboard trim is a piece of molding that is installed at the bottom of an interior wall. It covers the joint between the wall and the floor, and it can also provide a decorative touch.

Baseboard Trim

Baseboard trim is typically made from wood, but it can also be made from other materials, such as MDF, PVC, or vinyl.

Baseboard trim serves a few important purposes:

  • It covers the unsightly joint between the wall and the floor.
  • It protects the wall from damage from furniture and foot traffic.
  • It can add a decorative touch to the room.
  • It can help to create a more finished look.

There are many different styles of baseboard trim available, so you can choose one that matches the décor of your home.

Some popular styles include:

  • Plain: This is a simple, unadorned style that is often used in traditional homes.
  • Decorative: This style features intricate carvings or moldings.
  • Crown: This style is taller than traditional baseboard trim and is often used to create a more formal look.
  • Skirting: This style is used to cover the bottom of stairs.

When choosing baseboard trim, it is important to consider the following factors:

  • The height of the baseboard: The height of the baseboard should be proportional to the height of the room.
  • The style of the baseboard: The style of the baseboard should match the décor of the room.
  • The material of the baseboard: The material of the baseboard should be durable and easy to care for.
  • The budget: Baseboard trim can range in price from a few dollars to several hundred dollars per linear foot.

Once you have considered these factors, you can choose the baseboard trim that is right for your home.

Here are some tips for installing baseboard trim:

  • Start by measuring the length of each wall.
  • Cut the baseboard trim to length.
  • Apply a bead of caulk to the back of the baseboard trim.
  • Nail or screw the baseboard trim to the wall.
  • Fill in any nail or screw holes with putty.
  • Sand and paint or stain the baseboard trim.

With proper care and installation, baseboard trim can add a touch of elegance to any room.

What is a 16-Gauge Nailer?

A 16 gauge nailer is a type of nail gun that uses 16 gauge nails. These nails are 1.625 mm in diameter and have a small head, making them ideal for finishing projects.

16 gauge nailers are typically used for tasks such as:

  • Installing interior trim
  • Attaching baseboards
  • Nailing down flooring
  • Securing crown molding
  • Attaching chair rails
  • Framing windows and doors

16 gauge nailers can be either pneumatic or cordless. Pneumatic nailers are powered by compressed air, while cordless nailers are powered by batteries.

Pneumatic nailers are typically more powerful and can drive nails faster, but they require an air compressor. Cordless nailers are more portable and convenient, but they have a shorter battery life.

When choosing a 16 gauge nailer, it is important to consider the following factors:

  • Power: The power of the nailer will determine how quickly it can drive nails.
  • Magazine capacity: The magazine capacity is the number of nails that the nailer can hold before reloading.
  • Nail length: The nailer should be able to drive nails of the desired length.
  • Weight: The nailer should be lightweight and easy to maneuver.
  • Price: Nailers can range in price from a few hundred dollars to several thousand dollars.

Once you have considered these factors, you can choose the 16-gauge nailer that is right for your needs.

Here are some additional things to keep in mind when using a 16-gauge nailer:

  • Always wear safety glasses when using a nail gun.
  • Make sure the nailer is properly aligned before firing.
  • Do not over-drive the nails.
  • Dispose of used nails properly.

With proper care and use, a 16 gauge nailer can be a valuable tool for a variety of finishing projects.

What Is An 18-Gauge Nailer?

An 18 gauge nailer is a type of nail gun that uses 18 gauge nails. These nails are 1.27 mm in diameter and have a small head, making them ideal for delicate work.

18 gauge nailers are typically used for tasks such as:

  • Attaching trim
  • Securing molding
  • Upholstery
  • Light framing
  • Cabinetry
  • Model building

18 gauge nailers can be either pneumatic or cordless. Pneumatic nailers are powered by compressed air, while cordless nailers are powered by batteries.

Pneumatic nailers are typically more powerful and can drive nails faster, but they require an air compressor. Cordless nailers are more portable and convenient, but they have a shorter battery life.

With proper care and use, an 18 gauge nailer can be a valuable tool for a variety of projects.

Highlighting Some Differences Between an 18-Gauge Nailer and a 16-Gauge Nailer

The main difference between an 18-gauge nailer and a 16-gauge nailer is the thickness of the nails they use. 18-gauge nails are thinner nails and have a smaller head than 16-gauge nails. They are sometimes called finish nailers or brad nailer. 

This makes them less likely to split the wood, making them ideal for delicate work. They leave a smaller hole needing to be filled and sanded over. 16-gauge nails are thicker and have a larger head, making them more suitable for heavier-duty tasks.

Here is a table that summarizes the key differences between 18-gauge and 16-gauge nailers:

Specification18-gauge nailer16-gauge nailer
Nail thickness1.27 mm1.625 mm
Nail head sizeSmallLarge
SuitabilityDelicate workHeavy-duty work
PowerLess powerfulMore powerful
WeightLighterHeavier
PriceLess expensiveMore expensive

Ultimately, the best type of nailer for you will depend on the specific project you are working on. If you are working with delicate materials, such as trim or molding, then an 18 gauge nailer is a good choice.

If you are working with thicker materials, such as framing lumber, then a 16-gauge nailer is a better option.

Here are some additional things to keep in mind when choosing a nailer:

  • The type of nails that the nailer uses: Make sure the nailer you choose uses the type of nails that you need.
  • The power of the nailer: The power of the nailer will determine how easily it can drive nails into the wood.
  • The weight of the nailer: The weight of the nailer can be important if you will be using it for extended periods of time.
  • The price of the nailer: Nailers can range in price from a few hundred dollars to several thousand dollars.

Once you have considered these factors, you can choose the nailer that is right for you.

Let’s Get Terminology Right as between 16-Gauge Nailers and 18-Gauge Nailers

First, let’s dispel the idea of mixing nails and nailers.  Nailers are designed to be used with specific nails in mind, so 18-gauge nailers use 18-gauge nails, and 16-gauge nailers use 16-gauge nails.  

Secondly, let’s make sure we’re using the same terms consistently. Brad nails and trim nails are not the same. Brad nails are thinner and have a smaller head than trim nails.

This makes them less likely to split the wood, making them ideal for delicate work. Trim nails are thicker and have a larger head, making them more suitable for heavier-duty tasks.

Here is a table that summarizes the key differences between brad nails and trim nails:

SpecificationBrad nailTrim nail
Nail thickness1.27 mm1.59 mm
Nail head sizeSmallLarge
SuitabilityDelicate workHeavy-duty work
VisibilityLess visibleMore visible
PriceLess expensiveMore expensive

A brad nailer shoots brad nails; trim nailers shoot trim nails.  A brad nailer is designed to fire 18-gauge nails, while a trim nailer is designed to fire 16-gauge nails. 18 gauge nails are thinner and have a smaller head than 16 gauge nails.

This makes them less likely to split the wood, making them ideal for delicate work. Trim nails are thicker and have a larger head, making them more suitable for heavier-duty tasks.

However, there are some brad nailers that can also fire 16 gauge nails, and vice versa. These are called combination nailers. Combination nailers are a good choice if you need a versatile tool that can handle a variety of tasks.

In general, brad nails are a good choice for trim work, such as installing baseboards or crown molding. Trim nails are a good choice for heavier-duty tasks, such as attaching plywood or framing lumber.

Here are some additional things to keep in mind when choosing between brad nails and trim nails:

  • The thickness of the material you are attaching: Brad nails are better for thinner materials, while trim nails are better for thicker materials.
  • The visibility of the nails: Brad nails are less visible than trim nails, so they are a good choice if you want a more finished look.
  • The price of the nails: Brad nails are typically less expensive than trim nails.

Ultimately, the best type of nail for you will depend on the specific project you are working on and the materials you are using. If you are unsure, it is always best to consult with a professional.

It can be a bit confusing, sure.  A brad nailer is for delicate finishing touches.  Brad nailers might struggle with hardwoods, plywoods, and MDF, as they aren’t strong enough to push the brad nails fully through.

Finish nailers and finish nails take over when the going is a bit tougher.  A finish nailer has the greater power you will need for denser materials. 

Which Is Better For Installing Baseboard?

18-Gauge Nailer with 18-Gauge Nails or 16-Gauge Nailer with 16-Gauge Nails?

An 18-gauge brad nailer is typically better for baseboard installation than a 16-gauge nailer. 18-gauge nails are thinner and have a smaller head, which makes them less likely to split the wood.

This is important when installing baseboards or decorative trim, as they are often made from thin materials. Additionally, 18-gauge nailers are typically lighter and more compact than 16-gauge nailers, which makes them easier to maneuver in tight spaces.

However, and this is a big however, if you are installing baseboards in a high-traffic area, you may want to consider using a 16-gauge nailer. 16-gauge nails are stronger and more durable, and they are less likely to pop out over time.

The material you are working with will also determine which to use, as the 16-gauge nailer with its 16-gauge nails will deal with hardwoods, plywoods, and MDF better than will the smaller gauge nailer and nails that will have greater holding strength.

Ultimately, the best type of nailer for you will depend on the specific project you are working on and the materials you are using. If you are unsure, it is always best to consult with a professional.

Here are some additional things to consider when choosing a nailer for baseboard installation:

  • The length of the nails: The length of the nails should be long enough to penetrate the baseboard and the wall framing.
  • The type of nails: You can use either finish nails or brad nails for baseboard installation. Finish nails are stronger and more durable, but they are also more visible. Brad nails are thinner and have a smaller head, making them less visible.
  • The power of the nailer: The power of the nailer will determine how easily it can drive nails into the wood.
  • The weight of the nailer: The weight of the nailer can be important if you will be using it for extended periods of time.
  • The price of the nailer: Nailers can range in price from a few hundred dollars to several thousand dollars.
