Step-by-Step Guide: Installing Trim Without a Nail Gun

Trim is an essential element when it comes to finishing off the look of a room. It adds a beautiful touch, hiding rough edges and gaps between walls, ceilings, and floors. Many people think that installing trim requires a nail gun, but that’s not necessarily the case. If you don’t have access to a nail gun, don’t worry! In this step-by-step guide, we’ll show you how to install trim without a nail gun, using alternative methods that are just as effective.

Before we dive into the installation process, it’s important to gather the necessary tools and materials. You’ll need a tape measure, miter saw or miter box, coping saw, hammer, nails, wood glue, sandpaper, and a level. Additionally, you’ll need the trim itself, which can be 1×4 or 1×6 boards, or you can opt for pre-made molding.

The first step in installing trim without a nail gun is to measure and cut the trim pieces to fit your walls. Use a tape measure to determine the length and height needed, and mark the measurements on the trim boards. Use a miter saw or miter box to make precise angle cuts for corners. If the corners are not 90 degrees, use a coping saw to cut along the profile of the trim. Sand the cut edges to smooth them out before installation.

Preparation and Tools

Preparation and Tools

Before installing trim without a nail gun, it is important to gather all the necessary tools and materials. This will ensure that the project runs smoothly and efficiently. Here’s what you’ll need:



  • Measuring tape
  • Miter saw or a hand saw with a miter box
  • Coping saw
  • Hammer
  • Chisel
  • Phillips screwdriver
  • Putty knife
  • Sanding block or sandpaper
  • Caulking gun
  • Paintbrush


  • Trim pieces
  • Nails
  • Wood glue
  • Wood filler
  • Caulk
  • Primer
  • Paint

Having these tools and materials on hand will make the installation process much easier and ensure that you have everything you need to complete the project. It’s always a good idea to double-check your inventory before starting to avoid any delays or interruptions during the installation.

Measure and Cut the Trim

Measure and Cut the Trim

Before you start installing the trim, you need to accurately measure and cut it to the correct dimensions. Here’s how:

  1. Begin by measuring the length of the wall or surface where you plan to install the trim. Use a tape measure to get an accurate measurement from one end to the other.
  2. Next, transfer the measurement onto the trim. Use a pencil or marker to mark the length on the trim.
  3. Using a miter saw or a hand saw, cut the trim according to the marked measurement. Ensure that you cut it at a 90-degree angle, so it fits perfectly when installed.
  4. If you need to install trim around corners or angles, you’ll need to make miter cuts. Measure the angle using a protractor or a miter gauge and adjust the saw accordingly to make accurate cuts.
  5. Repeat the measuring and cutting process for each piece of trim you need to install. It’s always a good idea to measure twice before making any cuts to avoid any mistakes.

Once you have all the trim pieces cut to the correct dimensions, you can proceed to the next step of installing them without a nail gun.

Position the Trim

Begin by measuring and marking the desired placement of the trim. Use a tape measure to measure the length of the area where you will be installing the trim. Mark the measurement on the wall or surface where the trim will be positioned.

Next, take your trim piece and hold it up to the marked measurement on the wall. Align the edge of the trim with the mark and use a level to ensure it is perfectly straight. Adjust as necessary.

Using a pencil, lightly trace along the edge of the trim onto the wall to create a guideline for positioning the trim.

Repeat this process for all the trim pieces you will be installing.

Apply Adhesive

Apply Adhesive

Before attaching the trim to the wall, you’ll need to apply an adhesive to ensure a strong and lasting hold. There are a few different types of adhesive that you can use for this step:

  • Construction adhesive: This is a popular choice for installing trim as it provides a strong bond and dries quickly. Apply the adhesive to the back of the trim in a zigzag pattern.
  • Adhesive caulk: This type of adhesive is similar to construction adhesive but has a caulk-like consistency. It is great for filling small gaps and cracks between the trim and the wall.
  • Adhesive tape: If you prefer a mess-free option, adhesive tape can be a good choice. Simply apply the tape to the back of the trim and press it firmly against the wall.

Regardless of the adhesive you choose, be sure to follow the manufacturer’s instructions for application and drying time. It’s also important to clean the surface of the wall before applying the adhesive to ensure a solid bond.

Tip: Apply the adhesive evenly and avoid using too much, as excess adhesive can cause the trim to warp or become misaligned.

Attach Trim with Screws

When installing trim without a nail gun, another option is to attach the trim using screws. This method can provide a strong and secure hold, especially for heavier pieces of trim.

Here is a step-by-step guide to attaching trim with screws:

  1. Preparation:
    • Measure and cut the trim pieces to the desired length.
    • Sand and finish the trim if necessary.
    • Ensure that you have the following tools and materials: screws, drill/driver, screwdriver bit, pencil, measuring tape, and level.
  2. Marking the Trim:
    • Hold the trim piece against the wall or surface where it will be installed.
    • Use a pencil to mark the placement of the screws along the length of the trim. Aim for approximately 12-18 inches between each screw.
    • Use a level to ensure that the trim is straight and aligned properly.
  3. Drilling Pilot Holes:
    • Using a drill/driver with a drill bit slightly smaller than the screws you will be using, drill pilot holes at the marked screw locations on the trim.
    • Make sure to drill the pilot holes deep enough to allow the screws to go in without splitting the trim.
  4. Securing the Trim:
    • Hold the trim piece in place against the wall or surface.
    • Using a screwdriver bit, drive screws through the pilot holes and into the wall or surface.
    • Make sure to drive the screws flush with the surface of the trim, but be careful not to overtighten and damage the trim.
    • Continue attaching the trim piece by driving screws into each pilot hole along its length.
  5. Finishing:
    • Fill any screw holes with wood putty or filler, and sand it down to create a smooth surface.
    • Apply any desired paint or finish to the trim to match the surrounding decor.

Attaching trim with screws can be a reliable alternative to using a nail gun. Just follow these step-by-step instructions, and you’ll have your trim securely installed without the need for a nail gun.

Fill Nail Holes

Once you have installed the trim using your chosen method, you will need to fill the nail holes for a finished look. Here is a step-by-step guide on how to fill nail holes:

  1. Start by gathering all the necessary materials. You will need wood putty or wood filler, a putty knife or a scraper, sandpaper, and a cloth.
  2. Using your putty knife or scraper, take a small amount of wood putty or wood filler and press it into the nail hole. Make sure to completely fill the hole and level it with the surface of the trim.
  3. Once the hole is filled, use the putty knife or scraper to smooth out the excess putty or filler. This will help create a seamless finish.
  4. Allow the putty or filler to dry according to the manufacturer’s instructions. This usually takes about 24 hours.
  5. Once the putty or filler is dry, use sandpaper to gently sand the area around the filled nail hole. This will help blend the patch with the rest of the trim.
  6. After sanding, wipe away any dust or debris with a cloth. This will ensure a clean surface for painting or staining.

Now that you have filled and sanded the nail holes, you are ready to paint or stain your trim to complete the installation process.

Sand and Paint

After installing the trim, the next step is to sand and paint it to achieve a smooth and finished look. Follow these steps to sand and paint your trim:

Materials You Will Need:

  • Sandpaper (medium grit)
  • Sandpaper (fine grit)
  • Sanding block
  • Paintbrush
  • Paint
  • Painter’s tape
  • Drop cloth or newspaper
  • Damp cloth

Step 1: Prepare the Work Area

Start by laying down a drop cloth or newspaper to protect the floor from paint splatters. If there are any delicate surfaces or nearby furniture, cover them with a drop cloth as well. Use painter’s tape to mask off any areas that you don’t want to paint, such as adjacent walls or windows.

Step 2: Sand the Trim

Take the medium-grit sandpaper and use it to sand down the trim. Sand in the direction of the wood grain, moving the sandpaper back and forth with firm, even pressure. Pay extra attention to any rough spots or imperfections, as the sanding will help smooth them out.

After you’ve gone over the entire trim with the medium-grit sandpaper, switch to the fine-grit sandpaper. This will help to further smooth the surface and create a better base for the paint.

Step 3: Clean the Trim

Use a damp cloth or sponge to remove any dust or debris from the sanding process. Wipe down the trim thoroughly, making sure to get into all the crevices and corners. Allow the trim to dry completely before proceeding to the next step.

Step 4: Apply a Primer (optional)

If you’re painting bare wood trim or if the existing paint is in poor condition, consider applying a coat of primer before proceeding to the final paint. The primer helps to seal the wood and provide a better surface for the paint to adhere to. Follow the manufacturer’s instructions for applying the primer and allow it to dry completely before moving on.

Step 5: Paint the Trim

Step 5: Paint the Trim

Using a paintbrush, apply a thin, even coat of paint to the trim. Start from one end and work your way to the other, maintaining a wet edge as you go. This will help prevent visible brush strokes and ensure a smooth finish.

Allow the first coat of paint to dry completely, following the manufacturer’s instructions for drying time. Once dry, apply a second coat of paint if necessary to achieve the desired coverage and finish. Allow the paint to dry completely before removing the painter’s tape.

Cleaning Up:

Once you’ve finished painting the trim, clean your brushes and other tools with soap and water. Dispose of any unused paint or paint cans properly, following your local regulations.

Cleaning Up

  • Use a damp cloth or sponge to wipe away any excess glue or caulking.
  • If the glue or caulking is dried and hardened, gently scrape it off with a putty knife.
  • Wipe down the area with a clean, dry cloth to remove any residue.

Touching Up

  • Inspect the trim for any gaps or uneven edges.
  • If you notice any gaps, fill them in with wood filler or caulking.
  • Smooth out any rough edges with sandpaper.
  • If desired, paint or stain the trim to match the surrounding walls or furniture.
