Installing door trim is a simple process that can be done with or without nails. If you're using a nail gun, you'll want to use 4d finish nails or 1 ½-inch, 15-gauge gun nails spaced about 16 inches apart. You'll also need a miter saw, tape measure, pencil, level, combination square, pry bar, caulk gun, sandpaper, and door casing. Start by measuring the reveal and marking a consistent reveal of 1/8 to 1/4 inch around the door frame. Then, place the casing leg in position, checking that it meets the floor and marking where the reveal on the jamb head meets the leg. Cut the leg with a miter saw set to 45 degrees and test the fit before nailing it to the jamb. Repeat the process on the other side, adjusting the cut if needed, and then nail the casing to the wall, paying attention to the joints.

What You'll Learn
Prepare the installation area
Preparing the installation area is key to achieving a better fit and finish when installing door trim with a nail gun. Here are the steps you should take:
Firstly, ensure you have the right tools for the job. You will need a combination square, a tape measure, a pencil, a level, a miter saw or miter box with a handsaw, and a nail gun. It is also recommended to wear protective glasses when using the saw.
Next, examine the space around the door frame. Measure the reveal—the small gap between the edge of the door jamb and the trim—to ensure a consistent reveal of around 1/8 to 1/4 inch (or 3mm) around the entire door frame. These marks will guide the positioning of the trim.
Before installing the trim, check that the jamb and wall are flush. If not, plane projecting jambs to be flush with the wall if possible, ensuring the trim will sit flat against the wall.
When you are happy with the measurements and markings, you are ready to begin installing the trim. Place the trim in its intended spot, ensuring it is not too close to the hinges, as this may impede the operation of the door.
If you are replacing existing trim, carefully remove the old trim with a pry bar, being careful not to damage the wall or door frame. Remove any remaining nails and sand down rough spots to smooth the surface for the new trim.

Measure and mark the trim
To measure and mark the trim, start by outlining the reveal—the small gap between the door jamb and the trim. Use a combination square to mark a consistent reveal of 1/8 to 1/4 inch around the entire door frame. These marks will guide the placement of the trim.
Next, take a piece of trim and place it on the hinge side of the door, ensuring that about 3mm of the jamb is showing. The reveal must be even from top to bottom so that the trim will be straight. Do not place the trim too close to the hinges, as this may affect the operation of the door.
Once you're happy with the placement, use a pencil to mark the trim about 3mm past the corner where the door jamb meets the header. This mark indicates where you will cut the trim at a 45-degree angle.
Repeat this process for the other side of the door. Measure the length of the side piece from the inside corner of the head moulding to the floor, and make a mark. This will ensure that the trim is cut to the correct length and fits well.
If you are installing trim with mitered joints, you will need to cut the legs at a 45-degree angle using a miter saw. This will create a clean and precise cut.
Additionally, if the floor is uneven, you may need to trim the bottom of the trim leg to ensure it sits flat against the wall.

Cut the trim
Cutting the trim is a crucial step in the door trim installation process. Here is a detailed guide:
First, you need to take measurements and make calculations to determine the required length and angle of the trim pieces. Mark these measurements on the trim board, ensuring that the trim will be installed slightly away from the jamb edges to prevent unintentional gaps over time. This gap is called the “reveal". The reveal should be consistent, usually around 1/8 to 1/4 inch or 3mm, creating a balanced and symmetrical appearance around the door.
When marking the trim, position it on the hinge side of the door, ensuring that about 3mm of the jamb is showing. The reveal must be even from top to bottom for a straight trim. Be careful not to place the trim too close to the hinges, as it may interfere with the door's operation.
Next, use a miter saw to cut the trim pieces to the marked lengths. For the pieces that meet at the corners, cut them at a 45-degree angle. This angle will ensure they fit together neatly. If you are installing trim with mitered joints, the miter saw should be set to 45 degrees. Wear protective glasses when cutting the trim to ensure safety.
After cutting the trim pieces, it is a good idea to test their fit. Place the cut pieces above the door jamb and adjust as needed. This step ensures that the trim aligns correctly and fits well before securing them in place.
Once you are satisfied with the fit, you can proceed to the next step of securing the trim pieces. If you are using a nail gun, be sure to avoid nailing too close to the edges to prevent splitting the wood trim. Alternatively, you can use a strong adhesive to attach the trim, eliminating the need for nails or a nail gun.

Secure the trim with a nail gun
Securing your door trim with a nail gun is a simple process, but it requires precision and accuracy. Here is a step-by-step guide to help you secure your door trim with a nail gun:
First, ensure that you have marked the trim about 3mm past the corner where the door jamb meets the header. This mark is crucial as it will guide your cut at a 45-degree angle. After cutting the trim piece, it's time to install it.
Place the cut piece of trim above the door jamb and test the fit. It is recommended to have someone assist you with this step to ensure accuracy. Once you are satisfied with the fit, it's time to secure the trim with the nail gun.
Use a nail gun or a pneumatic air compressor nail gun with a gauge of 16 or 18 to attach the trim to the door jamb. Be cautious not to split the wood trim; avoid nailing within a quarter-inch of the side edges and keep at least an inch away from the moulding's edge.
Nail the trim at regular intervals. For finish nails, space them about 16 inches apart. For securing the trim to the wall, use 6d or 2-inch nails. Ensure the casing sits tightly against the wall to avoid gaps. If necessary, shim behind the casing before nailing to prevent the nail from pulling the joint open.
Finally, use a nail set to drive the nail heads below the surface of the door trim. If you have used paint-grade trim, fill the nail holes with paintable putty. For stain-grade trim, opt for a wood filler that matches the natural colour of the wood. Allow the putty or filler to dry, and then sand it to create a smooth, flush finish.
By following these steps, you can securely install your door trim with a nail gun, enhancing the look of your doorway.

Fill and smooth the nail holes
Filling and smoothing nail holes is a crucial step in achieving a seamless and professional finish when installing door trim with a nail gun. Here is a detailed guide on how to fill and smooth the nail holes:
Prepare the Nail Holes: Before filling the nail holes, ensure that any excess adhesive or caulk is removed from the nail holes and the surrounding area. Use a razor blade or a painter's tool to carefully peel away any adhesive or caulk that may have seeped out during the installation process. A clean and clear surface is essential for achieving a smooth finish.
Select the Appropriate Filler: Choose a filler that matches the type of trim you are using. For paint-grade trim, use a paintable putty to fill the nail holes. This will ensure that the filler can be painted over for a uniform appearance. If you are using stain-grade trim, opt for a wood filler that closely matches the natural colour of the wood. This will help you achieve a seamless and discreet repair.
Fill the Nail Holes: Using your chosen filler, carefully fill each nail hole. Ensure that the filler is applied generously and evenly to fill the hole completely. Smooth out the filler with a putty knife or a similar tool to create a flat and level surface. Allow the filler to dry completely according to the manufacturer's instructions.
Sand the Filled Holes: Once the filler has dried, use sandpaper to gently sand the filled areas. Sand in the direction of the wood grain if applicable, and work until the filled areas are flush with the surrounding surface. This step will help you achieve a smooth and consistent finish, ensuring that the filled areas blend seamlessly with the rest of the trim.
Clean and Prepare for Painting: After sanding, use a soft brush or cloth to remove any dust or debris from the sanded areas. If desired, apply a primer to the filled areas to enhance adhesion and create a uniform base for painting. Choose a primer that is suitable for the type of trim and filler you are using.
Paint the Trim: Finally, paint the entire trim, including the filled nail holes, with your chosen paint colour. Ensure that the paint is suitable for the type of trim and that it matches the surrounding area. Allow the paint to dry completely, following the manufacturer's instructions, for a uniform and aesthetically pleasing result.
By following these steps and taking your time, you can effectively fill and smooth nail holes when installing door trim with a nail gun, resulting in a professional and polished finish for your project.
