What You'll Learn
Stainless steel nails are best for redwood trim
When it comes to choosing the right type of nail for redwood trim, stainless steel nails are the best option. Redwood, also known as Western Red Cedar, is a type of lumber that contains natural preservative oils. While redwood is a durable and attractive material for trim, it requires specific types of nails to avoid staining and corrosion issues.
Stainless steel nails are highly recommended for redwood trim due to their superior corrosion resistance. Unlike other types of nails, stainless steel nails will not react with the natural preservative oils in the redwood, preventing unsightly stains and streaks. This is especially important if you plan to finish your redwood trim with a transparent stain, as stainless steel nails will not interfere with the desired aesthetic.
Additionally, stainless steel nails offer increased strength and durability compared to other options. The strength of stainless steel fasteners is particularly important for structural applications, such as earthquake retrofitting or outdoor decks, where the nails need to withstand significant stress and loads. Stainless steel nails will also last longer in exterior applications or high-moisture interior environments, as they are less likely to rust or disintegrate over time.
While hot-dipped galvanized nails are suitable for pressure-treated lumber, they are not ideal for redwood. The coating on galvanized nails can react with the oils in the redwood, causing staining and corrosion. Stainless steel nails, on the other hand, will not corrode or break down, ensuring the integrity of your redwood trim project.
It is worth noting that stainless steel nails are generally more expensive than other options. However, the increased cost is justified by their superior performance and longevity. You can easily find stainless steel nails at any local or online industrial supply or building supply store.

Avoid hot-dipped galvanised nails
While galvanised nails are commonly used to avoid rust and corrosion, there are certain types of wood, such as redwood, that are not compatible with galvanised nails. This is due to the chemical reaction between the zinc coating of the nail and the natural preservative oils in the wood, which can cause unsightly staining and streaking.
Hot-dipped galvanised nails are formed by submerging nails in a vat of molten zinc, which creates a thick, uniform zinc coating that offers superior protection against rust and corrosion. While this process is effective for many types of lumber, it is not suitable for redwood. The coating can react with the natural oils in the wood, causing staining and discolouration.
Hot-dipped galvanised nails are also not ideal for redwood trim because they can leave glossy spots at the nail sites. For a clean finish, it is recommended to use nails with textured heads, such as stainless steel nails, which are specifically designed for use with redwood.
Additionally, hot-dipped galvanised nails may not provide the best value for money. While they are less expensive than stainless steel nails, their zinc coating can react with the wood, leading to premature corrosion. This can result in the need for costly repairs or replacements.
Finally, it is important to consider the specific requirements of your project. If you are working with redwood trim in a high-moisture environment, it is crucial to choose nails that can withstand these conditions without corroding. In such cases, stainless steel nails are the recommended option, as they offer superior resistance to corrosion and staining.

Use brad nails for a clean finish
Brad nails are made of 18-gauge wire and are typically 1/2-inch to 2-inches long. They are smaller in diameter and have a smaller head compared to finishing nails. Their small size and head make them a good choice for wood trim, moulding, or other decorative wood surfaces. Their subtle appearance provides a clean finish in various woodworking projects.
Brad nails are ideal for thinner cuts of lumber, such as fibreboard and plywood. They are also suitable for light-duty projects or delicate materials, crafts, and projects using softwoods. They can be used as temporary fasteners while glue dries. Brad nails are easier to conceal than finishing nails and are less likely to cause wood splitting.
However, brad nails bend easily due to their high gauge and small diameter. They are notoriously difficult to drive by hand because of their small size, which makes them challenging to hold. Bending or missing a nail can cause damage to your project. Therefore, it is often more advantageous to use an electric or pneumatic nail gun to drive brad nails.
Finishing nails, on the other hand, are typically made of 15- or 16-gauge wire and range from 1-inch to 3 1/2-inches in length. They are very thin and made to disappear when hammered into wood. Finishing nails are stronger than brad nails and are ideal for applications requiring more strength and holding power, such as crown moulding, panelling, cabinetry, and larger trim. They are also more suitable for thicker wood and heftier projects.
When choosing between brad nails and finishing nails, consider the thickness of the wood and the strength required for your project. Brad nails are perfect for a clean finish on thinner wood, while finishing nails are better for thicker wood and projects needing more holding power.

Finishing nails are thin and strong
When working with redwood, it is recommended to use stainless steel nails. These nails are non-corrosive and will not cause staining or disintegration. Hot-dipped galvanized nails, which are suitable for pressure-treated lumber, should be avoided as they can react with the oils in the wood and cause staining.
For redwood trim specifically, finishing nails are an ideal choice. Finishing nails are very thin and designed to disappear when hammered into the wood. Despite their thin profile, they are strong enough to securely hold trim in place. They are commonly used in fine carpentry and cabinetry, as well as for moulding and trim applications. Their small heads can be driven flush with the wood or countersunk for a concealed appearance.
The thinness of finishing nails helps to minimize the chances of splitting the wood, which is particularly important when working with redwood. By avoiding driving multiple nails along the same grain line, you can further reduce the risk of wood splitting. Additionally, the choice of nail length is crucial. Nails should be long enough to penetrate at least 1-1/2 inches into the solid wood, ensuring a secure hold.
Finishing nails are available in various sizes, allowing for flexibility in your project. They are often made with a small diameter shaft, typically ranging from 16- to 10-gauge. This design feature not only reduces the likelihood of splitting but also enables them to be inconspicuous, especially when used in combination with glue or adhesive coatings.
Overall, finishing nails offer a combination of strength and inconspicuous appearance, making them a preferred choice for redwood trim. Their thin profile, variety of sizes, and holding power contribute to their effectiveness in trim applications while preserving the beauty of the wood. Remember to wear eye protection and exercise caution during the nailing process to ensure a safe and successful project outcome.

Common nails are used for framing
When it comes to choosing the right type of nail for your project, there are many options. Nails are used to fasten pieces of material together, and there are almost as many types of nails as there are projects.
Common nails are the go-to choice for many framing, construction, and carpentry jobs. They feature a heavy shank that provides sturdy support for framing and other rough work. The round head of a common nail remains visible on the surface. This type of nail is ideal when strength and functionality take precedence over appearance.
Common nails are similar to framing nails, but the latter are thinner and have flat heads. Framing nails are often coated so they can be easily driven flush or countersunk. They are also similar to box nails, which have thinner shanks and are less likely to split thinner pieces of wood.
If you're working with redwood, such as Western Red Cedar, it's recommended to use stainless steel nails to avoid corrosion and staining. Hot-dipped galvanized nails are also an option for outdoor use due to their thicker zinc coating, but they may react with the natural oils in redwood, causing stains.
For trim work, especially exterior trim, trim nails are specifically designed for this purpose. They secure gutters, fascia, and soffit boards, in addition to exterior trim. Brad nails, a smaller version of finish nails, are also suitable for trim, moulding, and other decorative wood surfaces. They provide a clean finish and have sufficient holding strength for woodworking.
