Wallpapering around a window and the reveals can be a great way to test your patience. Sometimes it can be straightforward, whilst other times, depending on the walls and wallpaper, it can be testing to say the least.
The method described below is the one I have used in the past and I have been generally happy with the finished results.
Extra care has to be taken when wallpapering around windows and reveals as the wallpaper can tear more easily because as the cuts take time to do, the wallpaper has more time to soak.
I always start as shown in fig 1, with wallpaper strip No 1, this strip when cut as shown will cover a section of the wall above the window.
A section of the top window reveal and 1/2″ (12mm) of the top of the side reveal.
This 1/2″ (12mm) section is to hide any discrepancies if the window reveal is not square when the next strip of wallpaper is hung in place (No 2).
Use your wallpaper brush to remove any air bubbles and push the wallpaper into the corners ready for trimming (see post on pasting and hanging wallpaper).
Fig 2 shows where to cut wallpaper strip No 2.
This strip will cover a section of wall above the window, the side reveal and a section of wall below the window. Although there will be a small overlap of wallpaper above the window I have always found this to be virtually unnoticeable, even less so when curtain rails etc, are fitted in place.
Use your plumb line to ensure the strip hangs perfectly vertical before making any cuts for the reveal and window sill.
I personally prefer to repeat this method on the opposite side of the window and then hang wallpaper strips to cover the gaps in between the top and bottom of the window and the top reveal.
As I wrote earlier in this post, any small overlaps of wallpaper are generally unnoticeable as they are hidden by curtain poles above and radiators below the window etc.
If the overlaps won’t stick down very well, let the paper dry and use overlap or border adhesive to overcome the problem.
Remember to wipe clean the window frame and sill of any wallpaper paste that may be present.
