Installing door casing is a common DIY project that can enhance the look and functionality of your doors. While nail guns are a popular choice for this task, not everyone has access to one. The good news is that you can install door casing without a nail gun by using simple hand tools. In this step-by-step guide, we’ll walk you through the process.

What You’ll Need

Before you start, gather the following tools and materials:

1. Door Casing: Measure and cut the casing to fit the dimensions of your door frame.

2. Handsaw: For cutting the casing to the correct lengths.

3. Miter Box and Saw: For making angled cuts at the corners.

4. Hammer: A standard claw hammer for driving nails.

5. Finishing Nails: Choose nails that are long enough to secure the casing but won’t protrude through the frame.

6. Wood Putty: For filling nail holes and gaps.

7. Sandpaper: To smooth the surface before painting or finishing.

8. Safety Gear: Safety glasses and work gloves are essential.

Step-by-Step Guide

Follow these steps to install door casing without a nail gun:

Step 1: Measure and Cut the Casing

1. Measure the height and width of the door frame. Cut your door casing pieces accordingly, adding a few extra inches for adjustments.

Step 2: Make Angled Cuts

1. If your door frame has corners that aren’t 90 degrees, use the miter box and saw to make angled cuts at the casing ends. Ensure they match the angle of the frame.

Step 3: Dry Fit the Casing

1. Before attaching the casing, dry fit it against the door frame to ensure it fits correctly. Make any necessary adjustments.

Step 4: Position the Casing

1. Apply a bead of wood glue along the back of the casing, especially at the mitered corners.

2. Position the casing against the door frame, ensuring it’s flush with the wall surface and the top is level.

Step 5: Secure with Finishing Nails

1. Using your hammer, drive finishing nails through the casing into the door frame. Place the nails every 12-16 inches along the casing, keeping them about 1 inch from the edge to avoid splitting the wood.

2. Sink the nail heads slightly below the surface of the wood.

Step 6: Fill Nail Holes and Gaps

1. Use wood putty to fill the nail holes and any gaps between the casing and the wall.

Step 7: Sand and Finish

1. Once the putty is dry, sand the surface of the casing to create a smooth finish.

2. Paint or stain the casing to your desired color and finish.

Step 8: Clean Up

1. Remove any excess putty or paint splatters from the wall, floor, and casing.

Tips for Success

• Be precise when measuring and cutting the casing to ensure a snug fit.

• Take your time with the mitered corners to achieve clean, tight joints.

• Use the appropriate size and type of finishing nails for your casing material.

• Ensure the casing is level and plumb before securing it with nails.

• Wipe away excess wood glue or putty immediately to avoid unsightly smudges.

Installing door casing without a nail gun is a practical and achievable task with the right tools and attention to detail. With patience and care, you can create a professional-looking door frame that adds a polished touch to your home.
