Some Crucial Tips & Tricks For Cutting Wallpaper

Going for a DIY wallpaper installation? Well, you should precisely follow these tips and tricks to avoid mistakes and prevent damages to your valuable investment.

  1. The 2-Inch Rule: Even professionals when cutting wallpaper take into account the possibility of wrong cuts and therefore, leave an additional 2 inches around the top and bottom part of the wallpaper. It proves to be significantly helpful for making pattern corrections and rectifying mistakes.
  2. The Sharp Blade: As already explained above, the importance of using a sharp blade gets highlighted again.
  3. Small Cuts: Always cut the wallpaper in small sections and on a flat surface. Avoid making one long cut even when going straight.
  4. Measure Twice, Cut Once: Check twice for the right measurements before cutting the wallpaper.
  5. Draw Pencil Marks: You can draw pencil marks for efficient cuts and trims. This way the chances of errors are minimized to a great extent.
  6. Use Scoring Tool: If you’re dealing with thick, textured wallpaper surfaces, use a scoring tool for added efficacy in cutting the wallpaper.

The Best Approach To DIY Wallpaper Cuts & Trims

We’ve explained below the best approach to cut the wallpaper for efficient and precise installations.

Cutting Dry Wallpaper

With more resistance to the sharp blade of a knife, dry wallpapers account for easy cuts and trims. Actually, dry wallpapers are stiff and therefore, scissors can be used to make cuts. Also, there is less possibility of irregular cuts and rough edges, this way.

If you’ve ever made cuts in wrapping paper using scissors, the scissors pushed along the paper, and cutting the surface was the way to go. Just like that, dry wallpaper cuts are easy to make, however, one should be careful as mistakes can still happen due to negligence.

Cutting Wet Wallpaper

When cuts are to be made after adhesive applications to the wallpaper, the chances of tearing, wrong cuts, and similar mistakes get multiplied. That’s because the wallpaper surface offers no resistance to the blade of the knife. In these situations, you need to be very careful to avoid ripping the wallpaper to pieces.

Cutting The Wallpaper Around Doors & Corners

You’ll surely encounter edges, corners, and curved surfaces when installing wallpaper. Obviously, there’s a need to cut the wallpaper around such areas for smooth wallpaper applications. So, what are the precautions to follow?

For this purpose, you should leave an additional 1 inch around the corner of the walls when the initial cut is to be made. Afterwards, you can opt for detailing around the corners with sharp scissors.

The ideal approach is to draw pencil marks for spot identifications. Never use a blade when cutting the wallpaper around the corners and edges because the stretched wallpaper surface creates strong tension to make tears along the way.

Cutting The Wallpaper For Obstructions

There may be obstructions due to sockets, electric boards, light switches, archways, fireplaces, and similar reasons. So, how do you cut the wallpaper around such obstacles, and what are the tools recommended for this purpose?

For straight 90-degree wallpaper cuts, you need to draw straight pencil marks leaving 1 or half an inch from all sides. It’s really important that you should never cut from right at the corner for 90-degree wallpaper cuts.

That’s because the created tension in the wallpaper surface, when alleviated, will pull the wallpaper more towards the adjacent walls, thus leaving behind gaps around the sockets and light switches. That will not look any good and you’ll surely regret that afterwards.

For that additional ½ inch or so that was left from all sides, you can easily adjust that under the electric board, socket, or light switch for a continuous and delightful wallpaper appearance.

The End Note

To precisely cut and trim wallpapers for efficient installations, the ideal approach combined with the right tool to be used is a must while being extremely careful as well. In this post, we’ve explained all the tools essential for wallpaper hanging and the importance of making sharp, regular wallpaper cuts. In addition, the ideal approach to different types of wallpaper cuts has also been discussed in detail.
