When it comes to nailing trim into drywall, there are several factors to consider for a secure hold. Firstly, identifying the location of wall studs is crucial, as they provide a more robust anchor for the nails. The spacing between studs can vary, so using a stud finder or rapping along the wall to detect hollow sounds can help pinpoint their positions. The nails should penetrate at least half an inch into the studs, and their length should account for the thickness of the drywall and trim. While nails can be driven directly into drywall, the hold may not be as strong. To enhance the grip, some people employ techniques like toe-nailing, where nails are driven at opposing 45-degree angles, creating a natural pinch that prevents the trim from falling out. Others opt for adhesives or use a combination of nails and glue, employing techniques like the dovetail nail technique to hold the trim in place while the glue dries. Power nailers and nail guns are also popular tools for efficiently nailing trim into drywall.

Using a nail gun
When using a nail gun, it is recommended to use a finish (trim) nail gun for installing baseboards. This type of nail gun has small heads that sink into the wood, making them barely visible and easy to plaster or paint over. To ensure a sturdy and secure hold, it is crucial to locate the studs along the wall using a stud finder and mark their positions before nailing.
When nailing the trim into the drywall, hold the nail gun at a slight angle and shoot two nails through the board at two different angles. This technique anchors the board to the drywall and provides a strong hold. It is important not to nail at too severe an angle, as this may cause the nail to miss the stud or not sit flush with the wall.
For added strength, you can also use construction adhesive or glue in combination with the nails. Apply dots of glue every few inches along the trim, being careful not to use too much to avoid a mess. Alternatively, you can use the "dovetail nail technique," where you nail at a 45-degree angle in one direction and then nail at a 45-degree angle in the opposite direction to create an "X" pattern with the nails. This provides additional support while the adhesive dries.

Locating studs
When it comes to locating studs for nailing trim into drywall, there are several methods you can use. Here are some detailed instructions to help you with the process:
Firstly, it is important to understand that studs are usually placed at specific intervals. In most cases, wall studs are spaced 16 inches apart from centre to centre. However, this may vary, especially in older homes where stud spacing can be inconsistent. Therefore, it is essential to locate each stud individually to ensure accuracy.
To locate the studs, you can use a stud finder, which will indicate the positions of the studs behind the drywall. Modern stud finders are reliable and can easily identify wall studs. Alternatively, a simple and cost-effective method is to rap gently along the wall with your knuckles. When you hear a more solid sound, or a less hollow sound, it indicates that you are likely knocking on a stud.
Once you have located a stud, it is crucial to find its centre. This ensures a strong connection when nailing the trim. A stud is typically 1 1/2 inches thick, so measure and mark the centre point accordingly. You can use painter's tape to mark the location of each stud, making it easier to visualise the stud placement.
When nailing into the studs, use trim nails that can penetrate at least 1/2 inch into the stud. Choose the right-sized nail by considering the thickness of the drywall and the trim board, in addition to the required penetration depth. Standard finish nails usually suffice, but some carpenters prefer galvanised finish nails for their firmer hold and rust resistance.
In addition to nails, you can also use adhesives to strengthen the bond between the trim and the drywall. General-purpose adhesives or even white glue can be used, but you must work quickly and use additional methods to hold the trim in place while the glue dries. Angled pins or the "dovetail nail technique" can be employed for this purpose.

Using glue
When attaching trim to drywall, gluing can be an effective method. A range of adhesives can be used, including general-purpose adhesives, white glue, and construction adhesive. It is important to note that construction adhesive may only be required for side mouldings, as they are likely to be completely between the studs. When using glue, it is crucial to hold the trim in place while the adhesive dries. This can be achieved by using angled pins, such as the "dovetail nail technique," or with dabs of hot glue between breaks in the adhesive.
To ensure a secure hold, it is recommended to use glue in combination with nails. Short pin nails or trim nails can be used, with galvanized finish nails being a popular choice among carpenters due to their firmer hold and rust resistance. Nails should penetrate at least half an inch into the studs. When determining the nail size, consider the thickness of the drywall and the trim board. For instance, if the drywall is half an inch thick, the nail should be long enough to penetrate half an inch into the stud, plus the thickness of the drywall and the trim board.
When nailing trim into drywall, it is important to locate the studs and nail into them, especially for the bottom nails. Studs are typically spaced 16 inches apart in newer homes, but older homes may have inconsistent stud spacing. A stud finder or stud sensor can be used to locate the studs. Alternatively, rapping along the wall and listening for a less hollow sound can help identify their locations.
To ensure a strong connection, find the center of the stud rather than just the edge. Additionally, when nailing near the end of a board, it is recommended to drill a pilot hole first to prevent splitting. The nail holes can then be filled and painted to create a seamless finish.
By combining the use of glue and nails, and following the tips outlined above, you can effectively attach trim to drywall and achieve a secure and aesthetically pleasing result.

Toenailing
When toenailing, it is important to locate the studs and ensure that the nails penetrate at least half an inch into them. Standard finish nails usually suffice, but some carpenters prefer galvanized finish nails for their firmer hold and rust resistance. If you're using a power nailer, keep in mind that trim nails are quite thin, so you may need to use more of them compared to hand nailing.
In addition to toenailing, adhesive can be used to enhance the bond between the trim and drywall. General-purpose adhesives or even white glue can be applied, and hot glue can be used between breaks in the adhesive to hold the trim in place while it sets. This technique is especially useful for gluing miters together.
To ensure a sturdy installation, it is recommended to find the studs and mark their locations with painter's tape before starting. A stud finder or simply rapping along the wall can help locate the studs. Toenailing, combined with adhesive and proper stud placement, will result in a secure and attractive finish.

Using a hand or power nailer
If you are using a hand nailer, you will need to purchase nails designed to be used with a hammer and several different sizes of nail sets to help insert the nail into the wall. Mark the studs on the wall with painter's tape and then nail into them. The distance between your nails will depend on the location of the studs. In most cases, trim should be attached to wall studs, which are usually (but not always) spaced every 16 inches. However, in older homes, stud spacing may be inconsistent, so you will need to find each stud individually.
To ensure a good connection, find the centre of the stud, as driving a nail into the stud's edge will result in a weak attachment. Trim nails should penetrate at least 0.5 inches into the studs. To choose the right-sized nail, add 0.5 inches (the thickness of the stud) to the thickness of the drywall (usually 0.5 inches) and the thickness of the trim board. Carpenters often prefer to use galvanised finish nails as they hold firmer and resist rusting. If you are driving a nail within 2 inches of the end of a board, drill a pilot hole first to ensure the board does not split.
If you are using a power nailer, you can use a nailer and/or a stapler. Short staples attach more firmly than short nails. Trim nails for power nailers are quite thin, so you may need to use more of them than you would if you were hand-nailing. You can buy a power nailer that is powered by a compressor or one that is powered by cartridges. The latter is typically more expensive, but it does not require a compressor or hose.
