Discovering the contour of a wall becomes apparent when attempting to fit a cabinet against it. Initially, a wall may seem straight, but achieving complete straightness is nearly impossible, even for the most skilled drywall expert. To accommodate for this, most cabinets include an additional filler piece that can be placed between the cabinet and the wall as needed. This filler not only creates a seamless fit but also allows for the necessary space to open drawers and doors without damaging the wall. The good news is that installing these fillers is a simple task that anyone can do.

Essential Materials

Prior to starting the installation process, it is important to determine the exact space that needs to be filled. Position the cabinet in the corner where it will be placed and measure the gap between the cabinet’s edge and the wall. Ensure that your filler piece is at least as wide as this gap. If the fillers provided with your cabinet are not large enough, you can find a variety of finishes available for purchase at your local hardware store.

The reason why your filler should be at least as wide as the required measurement is because you will need to cut it to fit perfectly. Additionally, you will need a scriber to mark the cutting line on the filler and a saw to accurately cut the wooden strip to the desired size. If the filler piece does not match the stain of your cabinets, you will also need to prepare it accordingly.

Installation Process

Once the cabinet is installed, measure the gap between the front of the cabinet and the wall. Remember that this gap may vary from top to bottom, so it is important to measure both ends. Select a filler strip that is at least as wide as the widest part of the gap and secure it to the cabinet using tape, allowing any excess to overlap the cabinet.

Using the scriber, mark a cutting line on the filler. Remove the filler and take it to a worktable for cutting. It may be necessary to clamp it to the table and use a circular saw to remove the excess, making sure to cut just beyond the marked line. To create a smooth edge, use a planer to file down the remaining material. Once the filler is the correct size, gently tap it into place by using a protective block of wood at the top and lightly hitting it with a hammer. Finally, sand the filler to achieve a polished finish.

Installing kitchen cabinet fillers is an enjoyable do-it-yourself project that can be completed over a weekend. Ensure that you have all the necessary tools before beginning and you will find that you can easily overcome any challenges that arise during the installation process.
