Common wallpaper problems: Bubbles.

Common wallpaper problems: Bubbles.

Many problems can occur when undertaking a wallpaper job – having ‘bumps’ or ‘bubbles’ in the wallpaper can be one example of such problems. Bubbling wallpaper is generally caused by a lack of a good bond between the wallpaper and the wall. Obviously this need not ever be a problem as preventative measures can be taken (i.e. ensuring you have a good ratio of the amount of paste and thickness per wallpaper piece.)

If you experiencing bubbling of the wallpaper then don’t panic as steps can be taken to eliminate this problem. In this article we will look at ways this can be achieved.

Firstly (and as best as you can) feel the bubble and the area around it. This should help you determine whether air is trapped behind it or something else. If the result is the latter (such as a piece of chipped plaster) then you will need to take other steps to remedy the issue, as this may be part of a bigger problem. The following remedial steps are related to trapped air.

Next thing to do is cut the wallpaper or make some kind of incision to release the air. Some people like to make a ‘tear’, while others make a cross or plus sign shape.

The most important thing to remember is to try and make the slit as small as possible as the aim is to conceal it and return it to normal after.

The second step is to try and smooth the bubble out so the wallpaper becomes flat. A simple case of applying light pressure with your hand should do the trick. Be careful not to tear or otherwise damage the wallpaper.

The third step is to in insert glue into the newly exposed area. This can be done with a little brush or even an item such as a syringe which will deliver a narrow but concentrated supply of paste.

Once you have pasted the area, smooth the wallpaper out in the normal way, just as though you have hung it for the first time. Again, avoid pressing too hard as you can cause the wallpaper to rip / tear.

If inadvertently you have got paste on other parts of the wallpaper, remove this with a damp cloth to avoid a residue / coat forming.

Finally allow to dry, and with any luck you should be bubble and bump free!
