Why does wallpaper bubble

Removing wallpaper can be a hassle, particularly tough textures such as woodchip. Whilst steamers can be effective, they are also quite expensive to buy or rent. For future reference, our Superfresco Easy wallpaper is just as simple to remove as it is to put up, removing the need for endless scraping or steaming.

It really has revolutionised the whole decorating process, and with so many different designs to choose from - the image above depicts our Eden Exotic wallpaper, which is part of our paste-the-wall collection - the world is your oyster. Wallpapering too early on wet plaster can lead to peeling, bubbles and mould due to moisture trying to escape from underneath. Despite your eagerness to get things done, you must relax and take your time when it comes to finishing off your room with fresh wallpaper.

Even paint can crack and bubble under the pressure built up from water escaping the drying plaster. On the other hand, 3mm skim above plasterboard or chipped wall can take as little as a week.

Condensation will also start to form on the windows which is a sign of plaster still drying, so take note of these tell-tale signs before diving in headfirst with your wallpapering. Select a type that is less likely to shrink, such as a canvas. Buy more wallpaper than you need. That way, if there are issues and you have to remove a strip more than twice, you can use a new sheet. The more times you apply a strip, the more it is overworked, and the more likely it is to shrink.

How do you smooth out air bubbles under contact paper? Using the point of the blade, poke a tiny hole in the middle of the bubble using your fingers to smooth the air out. You can also use just a pin to poke a little hole in it. If you want to remove old contact paper, just blow the hair dryer on it and it comes off in nothing flat. Do bubbles come out of wallpaper when dry? Most blisters and bubbles disappear after the wallpaper has had time to dry, so don't worry too much.

Is it better to paste the wall or wallpaper? As its name suggests, 'Paste the wall' papers allow you to apply your paste to the wall before hanging, rather than to the back of the wallpaper. Yes, if you find it easier to hang conventionally then you can paste the back of Paste the wallpapers. It's still quicker as there is no 'soaking time'. How long do you leave paste on wallpaper before hanging?

These bubbles can have a number of reasons. Often, they are caused by surplus wallpaper paste or air bubbles under the paper, but you can usually get rid off them very easily. Reasons for blisters in paper-based wallpaper Paper is made of wood, and paper-based wall materials consists of wood fibres, which will react to humidity.

As we all know, wood swells when in contact with water, and the same is true for the wood fibres contained in paper-based wallpaper.

When the paste is applied to a length of wallpaper, it expands in both length and width. This is why the correct soaking time is of such great significance. The wallpaper needs to be given sufficient time to absorb the liquid - and consequently to expand. The following instructions will explain how bubbles are created, and how you can remove them. The following instructions will explain how to get rid of blisters and bubbles. Further reasons for blistering Blisters are created when the underground surface is very absorbent and "soaks up" the wallpaper paste before it has a chance to develop its adhesive quality.

A sealed surface e. Sanded or rough surfaces also hamper adhesion. As a general rule, take time preparing the surface properly in order to prevent blisters and bubbles as much as possible. Using inappropriate paste or the wrong mixing ratio of water and powder can lead to decreased adhesive strength and thus to potential blisters. Always apply the wallpaper paste evenly on paper-based wallpaper or for non-woven varieties to the wall.

Be sure not to apply it too thickly or too thinly, as both will lead to decreased adhesion. As a result, blisters can appear in areas where too much paste was used, or areas which were too dry. The way the wallpaper dries is also an important factor. A draft, temperatures that are too high or too low, or high humidity, can lead to blisters. Ideally, the room temperature should be between 10 and 16 degrees Celsius. Even if you don't have a hygrometer, high air humidity can be indicated by a damp, cool room climate.

Always allow plenty of time for the wallpaper to dry out especially when the surface is going to be painted or overhung with decorative wallpaper — as with our products. Never try to speed up the process by advancing the drying process — such as turning the heating up in the room. This can result in the paper drying much more quickly than the paste behind meaning the paste does not have the time to bond the paper in its expanded state before it shrinks too quickly with the heat being applied — the result will again be lifting and shrinking.

All the above is especially important when the surface is going to be painted or overhung with a decorative product — as is the case of most of our Wallpapers. But if the bond strength is inadequate then once again lifting, especially at seams will result. Please note the paint will not penetrate all the way through the paper and be able to weaken the paste bond directly — the paint can only cause shrinking if the bond with the wall is too weak. This is a simple wallpaper calculator and should be used as a guide only.
