When it comes to installing hardwood flooring, choosing the right gauge nailer can be crucial for achieving a smooth and secure installation. There are several factors to consider when selecting a nailer, such as the thickness of the flooring and the type of subflooring being used. In this blog post, we’ll explore what gauge nailer is best for hardwood flooring and answer some frequently asked questions about this topic.

What is a nailer, and why do you need one for hardwood flooring?
A nailer is a power tool that’s used to drive nails into various materials. In the case of hardwood flooring installation, a nailer is typically used to secure the hardwood planks to the subflooring. Using a nailer is faster and more efficient than using a hammer and nails, as it allows you to drive nails quickly and accurately into the hardwood planks without damaging them.
What gauge nailer should you use for hardwood flooring?
The gauge of a nailer refers to the size of the nails it can drive. For hardwood flooring installation, the most common gauges are 15-gauge and 16-gauge nailers.
A 15-gauge nailer is recommended for thicker hardwood flooring, typically ¾-inch thick or more. This type of nailer uses thicker, heavier nails that provide better holding power and reduce the risk of splitting the hardwood planks. A 15-gauge nailer is also a good choice if you’re working with harder species of hardwood, such as hickory or oak, as these woods require more driving force to secure the planks.
A 16-gauge nailer, on the other hand, is best suited for thinner hardwood flooring, typically ⅜-inch to ½-inch thick. This type of nailer uses thinner nails, which are less likely to split the hardwood planks. If you’re working with softer species of hardwood, such as pine or cedar, a 16-gauge nailer may also be a good choice.
Ultimately, the gauge of nailer you choose will depend on the thickness and hardness of the hardwood flooring you’re installing.
What size nails for tongue and groove flooring?
Tongue and groove flooring is a popular choice for many homeowners due to its durability and aesthetic appeal. This type of flooring is made up of individual boards that interlock with one another, creating a smooth and seamless surface. However, one of the most common questions that homeowners ask when installing tongue and groove flooring is what size nails they should use.
Choosing the Right Nail Size:
When it comes to selecting the right nail size for your tongue and groove flooring, there are several factors to consider. These include the thickness of the boards, the width of the boards, and the type of subfloor you will be installing on. The following are some of the most common nail sizes used for tongue and groove flooring:
#16 Gauge Cleat Nails: This is the most popular nail size for tongue and groove flooring. These nails are typically 2 inches in length and have a sharp, pointed end that is designed to penetrate hardwood floors. #16 gauge cleat nails are perfect for 3/4-inch thick hardwood flooring and can be used on any subfloor, including plywood and concrete.
#18 Gauge Cleat Nails: These nails are slightly thinner than #16 gauge cleat nails and are 1 3/4 inches in length. They are suitable for thinner tongue and groove flooring, such as 5/16-inch or 3/8-inch thick boards. #18 gauge cleat nails can also be used on plywood and concrete subfloors.
#15 Gauge Finish Nails: These nails are thinner than #16 and #18 gauge cleat nails and are typically used for thinner tongue and groove flooring. They are 1 1/2 inches in length and have a flat head that sits flush with the surface of the wood. #15 gauge finish nails are ideal for 1/2-inch or 5/8-inch thick boards and can be used on plywood and concrete subfloors.
It is important to note that the nail size you choose will also depend on the width of the boards you are installing. For wider boards, you may need to use longer nails to ensure that the boards are secured properly.
Tips for a Successful Installation:
Once you have selected the right nail size for your tongue and groove flooring, the next step is to prepare the subfloor and the boards for installation. Here are some tips to ensure a successful installation:
- Prepare the Subfloor: Before installing your tongue and groove flooring, make sure that the subfloor is clean, level, and dry. Any debris or moisture on the subfloor can affect the stability of the boards and cause them to shift or buckle over time. Use a level to check the subfloor for any high or low spots and sand down any uneven areas.
- Acclimate the Boards: Tongue and groove flooring should be acclimated to the room where it will be installed for at least 48 hours before installation. This allows the boards to adjust to the temperature and humidity of the room, reducing the risk of warping or buckling after installation.
- Lay Out the Boards: Before nailing down the boards, lay them out on the subfloor to ensure a tight fit. Make sure that the boards are aligned properly and that the tongue and groove joints are tightly interlocked. Use a chalk line to mark a straight line for the first row of boards.
- Nail the Boards: Starting at one end of the room, use a flooring nailer to secure the boards to the subfloor. Make sure to drive the nails at an angle through the tongue and into the subfloor, leaving a small gap between the boards and the wall for expansion. Continue nailing down each board until you reach the opposite end of the room. Use a pry bar to snugly fit the last board in place, being careful not to damage the tongue and groove joint.
- Sand and Finish: Once all the boards are in place, use a floor sander to smooth out any rough spots or uneven areas. Sand in the direction of the grain, starting with a coarse grit sandpaper and working your way up to a finer grit. Finish the flooring with a stain or sealant of your choice, following the manufacturer’s instructions.
FAQs Gauge Nailer For Hardwood Flooring
Q: Can you use a finish nailer for hardwood flooring?
A: No, a finish nailer is not recommended for hardwood flooring installation. Finish nailers use much smaller nails than flooring nailers and are not designed for the heavy-duty work required for hardwood flooring installation. Using a finish nailer for hardwood flooring could result in a subpar installation that doesn’t hold up over time.
Q: Can you use a staple gun for hardwood flooring?
A: Yes, you can use a staple gun for hardwood flooring installation, but it’s not recommended. Staples provide less holding power than nails, and they can also be more likely to split the hardwood planks. Additionally, using a staple gun requires a different technique than using a nailer, which can be more difficult for beginners.
Q: Do you need to use a pneumatic nailer for hardwood flooring?
A: No, you don’t necessarily need to use a pneumatic nailer for hardwood flooring installation. While pneumatic nailers are the most common type of nailer used for this application, there are also electric and manual nailers available. However, pneumatic nailers are generally faster and more efficient than other types of nailers, making them a popular choice for professional installers.
Q: How do you choose the right length of nails for hardwood flooring?
A: The length of nails you need for hardwood flooring installation will depend on the thickness of the flooring and the type of subflooring being used. As a general rule, the nails should be long enough to penetrate through the hardwood planks and at least ¾-inch into the subflooring. Consult the manufacturer’s instructions for your nailer and flooring to determine the appropriate nail length. It’s also a good idea to do a test installation before starting your project to ensure that the nails are the right length and don’t protrude through the top of the hardwood planks.
Q: What are some common mistakes to avoid when using a nailer for hardwood flooring installation?
A: One common mistake is using the wrong gauge nailer for the thickness of the flooring being installed. This can result in nails that are too long or too short, leading to either insufficient holding power or nails that protrude through the top of the hardwood planks. Another common mistake is not properly adjusting the nailer’s depth setting, which can also lead to nails that are too long or too short. Make sure to carefully read the manufacturer’s instructions and test the nailer on scrap material before starting your installation.
Q: Can you use a nailer for engineered hardwood flooring?
A: Yes, you can use a nailer for engineered hardwood flooring, but it’s important to make sure that the nailer is appropriate for the thickness and type of engineered flooring you’re using. Engineered hardwood flooring can be thinner than solid hardwood flooring, so a 16-gauge nailer may be appropriate. Additionally, some types of engineered hardwood flooring are designed to be installed with glue instead of nails, so make sure to consult the manufacturer’s instructions before starting your installation.
Conclusion:
selecting the right gauge nailer for hardwood flooring installation is essential for achieving a smooth and secure installation. A 15-gauge nailer is recommended for thicker hardwood flooring, while a 16-gauge nailer is best suited for thinner hardwood flooring. It’s important to carefully read the manufacturer’s instructions and test the nailer on scrap material before starting your installation to avoid common mistakes and ensure a successful outcome.
