Polystyrene cornice is a popular and effective way to add style and sophistication to your home’s ceilings. However, when it comes to installation, cutting the corners of polystyrene cornice can seem daunting. Fortunately, with the right techniques and tools, cutting polystyrene cornice corners can be a breeze.
Tools you will need
The first step to cutting polystyrene cornice corners is gathering the necessary tools. Here are the tools you will need:
- Polystyrene cornice
- Cornice adhesive
- Tape measure or ruler
- Pencil
- Mitre box and saw
- Sandpaper
Measuring the cornice
The first step in cutting polystyrene cornice corners is accurately measuring the cornice. Measure the length of the wall where the cornice is to be installed and mark it on the cornice using a pencil.
Next, measure the angle of the corner where the cornice will be installed. In most homes, the angle will be 90 degrees, but it may vary in some cases. Use a protractor to accurately measure the corner angle.
Cutting the cornice
Once you have accurately measured the cornice, it's time to start cutting. The easiest way to cut a polystyrene cornice is by using a mitre saw. A mitre saw allows for precise, clean cuts that are essential when installing cornice.
Begin by placing the cornice into the mitre box, making sure that it is snugly fitted. Next, set the angle of the mitre box to match the angle of the corner where the cornice will be installed. This is where the protractor comes in handy.
Once you have set the angle and secured the cornice, use the saw to make a clean, accurate cut. Repeat this process for the other side of the corner to create a neat mitered corner.
Sanding the cornice
After cutting the cornice, it's essential to sand any rough edges for a smooth finish. Using fine-grit sandpaper, carefully sand the edges of the cornice until they are smooth to the touch.
Installing the cornice
With the cornice cut and sanded, it's time to apply the adhesive and install the cornice. Apply a thin layer of cornice adhesive to the back of the cornice and press it firmly into place along the wall. Hold the cornice in place for a few minutes to allow the adhesive to set.
Once the adhesive has set, any gaps between the cornice and the wall can be filled using a caulking gun and cornice adhesive. Finally, wipe away any excess adhesive with a damp cloth.
Conclusion
With the right tools and techniques, cutting polystyrene cornice corners can be a manageable task. Accurately measuring the cornice, using a mitre saw for clean cuts, sanding any rough edges, and installing with adhesive are all crucial steps to achieving neat, clean, and professional-looking corners.
