When it comes to attaching trim to drywall, there are a few methods that don't require nails. One popular method is to use construction adhesive, such as Loctite's Powergrab, or a strong glue suitable for wood and walls, such as carpenter's glue. To do this, cut your trim pieces to size, lay them face-down, and apply a wavy line of adhesive to the back. Then, add dabs of hot glue every 12 inches (30 cm) and press the trim into place, holding it until the glue hardens. You can also use angled pins to hold the trim in place while the adhesive dries. Alternatively, if you are set on using nails, it is recommended to nail into the wall studs, as drywall does not hold nails well.

What You'll Learn

Use construction adhesive
Construction adhesive is a popular choice for attaching trim to drywall without using nails. It eliminates the risk of drywall damage and provides a more discreet connection. Construction adhesive is also a good option if you are unsure about the location of your wall studs or if your wall doesn't have traditional wooden studs.
To use construction adhesive, start by cutting your trim pieces to the correct length and laying them out on a drop cloth, face-down. Then, apply the adhesive to the back of the trim in a wavy line or a continuous line, depending on the size of the trim. For smaller trim pieces, a 1/4-inch continuous line of adhesive along the back of the trim should suffice. For larger trim pieces, a 1/4-inch S-shaped line of adhesive about 1 1/2 inches from both edges of the trim is recommended.
It is important to note that construction adhesive can take hours to dry, so you may need to use hot glue to hold the trim in place while the adhesive sets. Apply a dab of hot glue every 12 inches (30 cm) along the back of the trim and press it into place. The hot glue will keep the trim in place as the construction adhesive dries, ensuring a precise and permanent installation.
Construction adhesive has several advantages, including its ability to create a strong, long-lasting bond on both porous and non-porous surfaces. It is also waterproof and resistant, making it suitable for moisture-exposed environments. However, there are some disadvantages to consider. Construction adhesive can be difficult to remove once it dries, and it may be quite expensive. Additionally, the smell of the adhesive can be strong and unpleasant, and it may be challenging to apply evenly.
Overall, using construction adhesive is an effective method for attaching trim to drywall without nails, providing a strong and discreet connection. However, it is important to consider the advantages and disadvantages before deciding on the best approach for your specific project.

Add hot glue for extra hold
When attaching trim to drywall, using construction adhesive is a great alternative to nailing. Construction adhesive can take hours to dry, so using hot glue as well will hold the trim in place while the adhesive cures.
To attach the trim to the drywall, first cut your trim pieces to the correct length and lay them face-down on a drop cloth. Next, apply a wavy line of construction adhesive to the back of the trim. Then, add a dab of hot glue every 12 inches (30 cm) along the back of the trim. Press the trim into place and hold it with equal pressure until the hot glue hardens. The hot glue will keep the trim in the correct position while the construction adhesive dries.
Hot glue on its own is not strong enough to install trim, but it is very useful for creating a temporary hold. Construction adhesive is much stronger and will permanently bond the trim to the drywall.
If you are attaching baseboards, you can use brace nails to hold the trim in place while the glue dries. Tap two thin nails into the baseboard at an angle so that they sink into the drywall. When the glue has dried, pull the nails out with pliers.

Use a caulk gun
Using a caulk gun is a great way to attach trim to drywall without using nails. This method involves using construction adhesive, which is just as effective as nails at holding the trim in place. The adhesive also eliminates the need to fill and cover nail holes, making the overall job easier.
To use a caulk gun, start by loading a tube of all-surface construction adhesive into the gun. Then, apply a thin bead of adhesive along the back of the trim. A wavy line application pattern is recommended, and remember that you don't need to apply a large amount. Too much adhesive can create a mess when you press the trim into place, as it may squirt out around the edges.
Once the adhesive is applied, position the trim onto the drywall and press and hold for several minutes. The construction adhesive can take hours to dry, so you may want to use hot glue in conjunction with the adhesive to hold the trim in place temporarily. Apply a dime-sized glob of hot glue every 12 inches (30 cm) along the back of the trim, then press your trim into place and hold until the hot glue hardens.
Allow at least 24 hours for the construction adhesive to fully cure and bond your trim to the drywall. This method provides a precise, permanent trim installation without using any nails.

Use brace nails
Although it may seem counterintuitive to use brace nails when attaching trim without nails, this method works with metal wall studs because the nails only go into the drywall.
To start, cut your trim pieces to the right length. Then, lay out all the trim pieces on a drop cloth, face-down. Apply construction adhesive to the back of the trim. Add a small amount of hot glue every 12 inches (30 cm) along the back of the trim. Press the trim into place and hold it until the hot glue hardens. The hot glue will hold the trim in place as the construction adhesive dries.
Now, tap a thin brace nail into the trim at an angle so that it sinks into the drywall but no further. Make sure the nail doesn't sink too deep. Tap a second brace nail at an angle in the opposite direction just under the first nail so that the two form a "V". Leave the glue to set overnight. Once the glue dries, use pliers to gently pull the brace nails straight out to avoid damaging the trim.
One benefit of attaching trim without nails is that you won't need to cover up any unsightly nail heads. If you do use nails, use an interior wood filler to fill and cover the nail holes. Allow the filler to dry, then sand it smooth. You can then paint the trim to cover the wood filler and any scuff marks.

Use angled pins
Angled pins are a great way to attach trim to drywall without using nails. This method, also known as the "dovetail nail technique", involves shooting 18ga 1¼" pins at an angle to keep the trim base in place while the glue dries.
To use this technique, start by applying a construction adhesive, such as Loctite's Powergrab, to the back of your trim piece. You can use a caulk gun to apply the adhesive in a wavy line, ensuring you don't use too much to avoid creating a mess.
Next, add a dab of hot glue every 12 inches (30 cm) along the back of the trim. Press the trim into place and hold it firmly until the hot glue hardens. The hot glue will create a temporary bond, holding the trim in place while the construction adhesive dries.
Once the glue has set, you can remove the angled pins using pliers to avoid damaging the wood. This technique ensures that you don't have to deal with unsightly nail holes, and it provides a strong and secure bond for your trim.
Using angled pins in combination with adhesive is an effective way to attach trim to drywall without using nails. It allows for a precise and permanent installation, making your project look neat and professional.
