Times have changed. Over the years, some things have also changed in the adhesive techniques. For example, wallpaper is no longer just painted in the traditional way, but can also be processed using the wall pasting technique. For many years, the pasting machine was reserved primarily for painters. But this is now also available for the hobby painter. In any case, the right technique and the right wallpaper paste is crucial.
The right wallpaper paste should be
To ensure that your wallpaper stays on the wall, you need to choose the right wallpaper paste. This is not so easy with the large number of different products in the trade. No wonder that you as a customer sometimes can not make a decision. After all, the paste must be matched not only to the wallpaper, but also to the gluing technique. In the trade, a distinction is made between the following pastes:
- normal paste made from methyl cellulose,
- special paste made of methyl cellulose and a synthetic resin powder,
- wallpaper paste for paste machines made of methyl cellulose and a synthetic resin powder,
- powder paste for plastic wallpaper on paper backing and textile wallpaper made of paper backing of methyl cellulose and a binder.
On top of that, some wallpaper manufacturers offer their own paste for special wallpapers, which is matched to the wallpaper. You should then prefer this.
The right wallpaper paste for your wallpaper
Depending on the type of wallpaper, the paste also varies. Not every paste is suitable for every wallpaper. And not always the good old cellulose glue is the best. Paper wallpaper with a vapor-permeable surface can be pasted with a simple paste (normal paste). But for heavy wallpaper with a surface of vinyl or metal, the normal paste is not enough. There you should choose a special paste.
With a special paste you are also better advised for heavy wallpapers such as textured wallpaper, woodchip and vinyl wallpaper. For very heavy vinyl wallpaper or wallpaper with excess width, it is recommended to add a dispersion adhesive to the special paste.
A special paste also need non-woven wallpaper. This paste should be written on it that the paste can be used for non-woven wallpaper.
It must be the right mixture
Gone are the days when everything was wallpapered with one glue - namely, the cell glue. Back then, the paste was dissolved in warm water and had to stand for 24 hours before being used. Today, some things are different. You should always stir in paste according to the manufacturer's instructions. And there, the recommendation is "cold water." If you use warm water, the consistency can be negatively affected and the paste will no longer stick. The reaction of the ingredients is accelerated and lumps are formed. In addition, warm water can not break down the cellulose, the adhesive strength decreases.
You should also adhere to the manufacturer's instructions when it comes to the quantities. Do not be irritated if the wallpaper paste is then thick like pudding. It has to be like that. If you thin the paste, it loses its adhesive strength.
How to mix the paste correctly
In a bucket, add the amount of water indicated on the paste package. If you do not need the whole package, you should weigh the powder so that the ratio is correct. Use clean containers to mix the paste. Once you have properly measured out the cold water, begin to create a vigorous swirl in the bucket with a stir stick or other stirring device. While stirring constantly, slowly pour the paste powder into the water. Continue to stir vigorously until there are no more lumps. The paste must then rest briefly. Refer to the manufacturer's instructions for resting times. After the swelling time, stir the paste again briefly and can now use the wallpaper paste.
Not all bonding technology is the same
Until a few years ago, there was only paper wallpaper. These had to give way for some time after pasting. Today, the materials have changed. In addition to the well-known paper wallpapers, there are also non-woven wallpapers, which you can process more easily. Here you can learn more about the gluing techniques.
Paste paper wallpaper - how to do it
With paper wallpaper, you must always paste the wallpaper. The wall pasting technique does not work with these wallpapers. Paint the wallpaper evenly and do not forget the edges and corners. When pasting the wallpaper requires some sensitivity. Neither too much nor too little paste should be applied.
Then put the strips of wallpaper together. Put the wallpaper together from each side to the middle. Now the whole web is folded again. For vinyl wallpaper, you should then roll everything together. So the edges do not roll up and dry out. The sheets must now give way. During this time, the paper absorbs the moisture and expands. The soaking time depends on the type of wallpaper. Only then are the strips applied to the wall.
Paste non-woven wallpaper - simply by wall gluing technique
You can apply non-woven wallpaper using the wall pasting technique. To do this, you stir the paste and apply them generously and evenly on the wall with a painter's roller or a paste brush. Paint in a little more than a web is wide. This way you can also glue the edges well.
Kommen Sie mit der Wandklebetechnik nicht zurecht, können Sie natürlich auch die Bahnen der Vliestapeten einkleistern. Wichtig: Vliestapeten dürfen nicht weichen. Kleistern Sie die Bahnen ein und bringen Sie diese sofort an die Wand.
Paste machine - when is it worth it?
Surely you have wondered whether it is not worth buying a paste machine. After all, the painter has such a device and with him everything looks super simple. With a pasting machine you can paste wallpaper evenly and more cleanly. You can paste all types of wallpaper with such a machine. However, before you buy it, you should ask yourself if it is worth it. If you only occasionally wallpaper, a purchase is usually not useful. However, should you take over the wallpapering work in the whole family, it is already worthwhile.
However, not all paste machines are the same. Very cheap models are not useful. Such models usually do not last long, are difficult to adjust and thus do not really facilitate the work. Rather invest a little more and buy a high-quality model. It does not have to be the professional wallpapering machine for 1,550 €, but the cheap model for 30 € should not be it either.
To paste wallpaper strips, you need to fill the paste into the tank of the wallpapering machine. Then adjust how much paste is applied to the web. Now clamp the wallpaper roll and pull it through evenly and slowly to the desired length.
For paste machines there are special wallpaper paste. But in principle, you can use any paste.
With our tips, you will certainly get the wallpaper paste easily on the sheets, so that they hold well on the wall. Of course, the correct surface treatment is important beforehand.
