Wall renovation: 8 mistakes you must avoid


Wallpaper is making a comeback in the home, whether on a living room wall or as a headboard in the bedroom. There are some important steps to take when installing a new panoramic wallpaper, patterned or single colour wallpaper.

Benefits of Interior Wall Renovation

Renovating an interior wall in your house offers numerous advantages.

Firstly, it enhances the aesthetics of your space by transforming a dull wall into an attractive focal point through new paint, wallpaper, or decorative finishes. This visual upgrade can increase the value of your property, making it more appealing to potential buyers or renters.

Additionally, renovations address structural issues such as cracks, holes, or water damage, ensuring the stability and safety of your home. By incorporating functional upgrades like built-in shelves, recessed lighting, or improved insulation, you can enhance the wall’s functionality and energy efficiency.

Renovating also allows for personalization, enabling you to express your style and creativity.

Furthermore, modifications to the layout or structure of an interior wall can optimize space utilization, whether it’s creating an open floor plan or dividing a room into smaller ones. By considering your budget, building regulations, and desired design, consulting with professionals can help ensure a successful wall renovation project.

8 mistakes you must avoid

  1. Wallpapering without checking the absorption of the wall

We frequently forget to check the absorbency of the wall before beginning to apply wallpaper. The wallpaper is applied to an unsuitable surface, fails to adhere, and peels off immediately. Check the porosity of the wall, which should be normally absorbent.

Take a wet sponge and press it against the wall. The wall is not absorbent if the drop falls quickly. It is an absorbent surface if the drop gradually fades and slides gently down the wall.

  1. Not respecting the soaking time

Before they can be hung, traditional wallpapers must be covered with glue on the reverse side. A soaking time is required prior to this step, which varies depending on the glue. It enables the glue to penetrate the paper. We frequently avoid these valuable minutes when we are in a hurry.

  1. Making a mistake on the number of rolls to buy

Calculating the number of rolls to purchase is not an easy task. There are some guidelines to follow. Calculators can also be used to obtain an automatic result. Remember that a strip can be torn or damaged during your calculation. The good news is that no matter how you count the number of rolls of wallpaper, always round up.

  1. Not using a spirit level

The others will follow if the first strip is installed at an angle. It will be completely tilted by the fifth strip… When laying the first strip, use a level or a plumb line to ensure that it is straight. Apply the first strip after drawing a light line with a pencil on the wall.

  1. Forget to have a sponge

The glue runs down the sides and into the joints as you trowel. We believe it vanishes when it dries. However, once dry, the glue is extremely difficult to remove and may even leave a shiny spot on the wallpaper. Be sure to have a sponge next to you.

  1. Not following the instructions on the glue pot

Each wallpaper has its own glue that is specific. A heavy vinyl wallpaper, for example, requires a glue designed specifically for thick and heavy paper. Even if you have some glue left over and want to apply another thin wallpaper, the outcome will be less than satisfactory.

  1. Wallpapering a corner

An outside corner, unlike an inside corner, is visible to passing traffic. We believe that the wallpaper can be cut on the corner for convenience. But it will quickly peel off. The good advice is that the wallpaper should cover the entire corner of the wall, even if it is only 5 cm.

  1. Painting the ceiling after wallpapering

If you want to repaint the room’s ceiling, you should do so before applying the wallpaper. Otherwise, keep an eye out for paint chips on the wallpaper! If you paint before putting up the wallpaper, the paint may spill over the surface to be pasted when you clear the corners.

The good tip: if some paint has spilled over, lightly sand the area to improve adhesion.
