How to Hang Wallpaper Around a Window

If you're wondering how to wallpaper around a window, the hanging method will depend on the type of wallpaper you're using. For unpasted wallcoverings, you'll apply adhesive to the paper and "book" it before hanging, while non-woven wallpapers may require pasting the wall. Check the wallcovering instructions for the best option for your paper.

Once you've determined the hanging method, tack the wallpaper over the window and adjust it as needed to match the pattern. Then, allow the excess paper to drape over the window and make relief cuts to remove it.

Relief cuts are diagonal cuts made in the wallpaper to allow it to lay flat and smooth around corners, edges, or obstacles like a window or door. Their purpose is to relieve the tension and allow the excess wallpaper to be removed cleanly.

Using Relief Cuts When Wallpapering Around a Window

First, locate the top corner of the window casing while the wallpaper is covering the window. Cut the wallpaper diagonally upward towards the corner using sharp scissors, so that it lays flat against the side and top of the casing.

Then, gently press the wallpaper against the vertical edge of the window and find the bottom corner. Cut diagonally downwards towards the corner of the window casing. This relief cut will allow the wallpaper to wrap around the side and bottom of the window.

Trimming Excess Wallpaper Around a Window

To trim the wallpaper and fit it into the window recess, begin by roughly cutting away the excess paper over the window. Clean any extra paste from the window glass and ensure the seams are tight. With your smoothing tool, press the paper along the edge of the window casing firmly.

Next, using a sharp snap blade knife and trim guide, cut away excess paper at the ceiling and continue trimming along the top and sides of the window casing, making sure to change blades frequently to avoid tearing the paper. Finally, wipe down the window casing with a damp rag to clean up any remaining wallpaper paste.

When wallpapering around a window, it's essential to use high-quality adhesives, primers, and tools to ensure a smooth and long-lasting finish. Choosing the right wallpaper paste and primer can prevent the paper from peeling or bubbling, while investing in wallpapering-specific tools can save you time and simplify the process.
