In the world of construction and carpentry, precision and efficiency are paramount. Every detail, down to the finishing touches, contributes to the overall quality of a project. One such detail often encountered in trim work is the installation of quarter round molding on plaster walls. To achieve a professional finish and save time, a brad nailer is the go-to tool for contractors and DIY enthusiasts. In this article, we’ll explore the art of using a brad nailer to secure quarter round molding onto plaster walls, providing valuable insights and technical details to help you master this craft.

The Beauty of Quarter Round Molding

Quarter round molding is a finishing touch that adds finesse and elegance to interiors. It’s commonly used to conceal gaps between baseboards and floors or to provide a smooth transition between walls and other surfaces. Installing it on plaster walls is a delicate process, and using the right tools is crucial.

Why Choose a Brad Nailer?

  • Precision: Brad nailers are designed for fine detail work. They drive 18-gauge brad nails, which are slender and leave minimal holes, preserving the aesthetic of your molding.

  • Efficiency: Brad nailers are pneumatic or cordless, making the installation process quicker and easier compared to manual nailing.

  • Reduced Damage: The small size of brad nails reduces the risk of damaging delicate molding pieces.

  • Flush Finish: Brad nailers are equipped with depth adjustment features, allowing you to drive nails to the perfect depth for a flush finish.

Selecting the Right Brad Nailer

Choosing the right brad nailer is the first step to success. Here are some key considerations:

  • Gauge: An 18-gauge brad nailer is the ideal choice for quarter round molding, providing a strong hold without causing excessive damage.

  • Power Source: Decide between pneumatic and cordless nailers based on your convenience and access to a power source.

  • Magazine Capacity: A larger magazine capacity reduces the need for frequent reloading, increasing your efficiency.

  • Depth Adjustment: Look for a nailer with tool-free depth adjustment to fine-tune the depth of your nails.

Steps to Perfect Installation

Now, let’s walk through the steps to secure quarter round molding onto plaster walls with a brad nailer:

Step 1: Prepare Your Work Area

  • Ensure the plaster surface is clean and free of debris.

  • Measure and cut your quarter round molding pieces to the required length with precision.

Step 2: Position the Molding

  • Position the quarter round molding in place, ensuring a tight fit.

  • Make sure the molding is level and aligns perfectly with the adjoining pieces.

Step 3: Load the Brad Nailer

Step 4: Nail Placement

  • Start by nailing the molding to the plaster wall at a slight angle to prevent splitting.

  • Space the nails at intervals of 6-8 inches along the length of the molding.

Step 5: Counter-Sink Nails

  • Use the depth adjustment feature to ensure the nails are countersunk slightly below the surface of the molding.

Step 6: Fill and Finish

  • Fill the small holes left by the nails with wood filler or putty.

  • Sand and finish the quarter round molding to achieve a flawless, smooth surface.


The art of using a brad nailer to secure quarter round molding onto plaster walls is a skill that elevates your craftsmanship. The precision, efficiency, and minimal damage provided by a brad nailer ensure that your finishing touches are impeccable. So, next time you’re working on an interior project, trust your brad nailer to handle the delicate task of securing quarter round molding, and watch your craftsmanship soar to new heights. It’s not just a tool; it’s your key to perfection.
