Frequently asked questions - ALF&mabi wallpapers


How do I calculate the number of rolls I need for my wall?

All wallpapers in our online shop have a roll calculator. The calculation automatically takes into account each specific model and whether or not the design has a case/rapport. Just add the measurements of your wall (width x height) in the fields and you will see the total amount of rolls needed for your wall.

How long does it take for the wallpaper to arrive?

Most of the products in our catalogue are in stock and are shipped quickly, within 1-2 working days. Other products are made to order and have a longer lead time, up to 10 working days. This information can be found in the description of each product on the website. Once the package leaves our warehouse, we send an email to the customer with a tracking link so that they can track and manage the delivery, which usually takes 24-48 hours.


Are the colours of the wallpaper the same as those seen on the website?

The shades that you see in the photos of our products are pretty close to the printed version of the roll. It is true that there may be a difference in shade from one screen to another, but what we see are very satisfied customers with our products, whose feedback is that the printed paper is much nicer than the online version. So we don't think there's a better thermometer than this :) In any case, if you order a roll and you see that the colour is not what you expected, you can return it to us as long as the product is unopened. Check our return policy here. 

Is it possible to order wallpaper samples?

Yes, we have samples of most of the wallpaper models in our catalogue available for purchase. The price of each sample is 5€ + shipping costs. The samples are sent within 4 working days and have an approximate size of 90cm x 60cm. If you are interested in ordering a sample, please contact us by email at informing the paper model and the delivery address of the samples. We will get back to you as soon as possible to finish processing your order :) In addition, if you decide to order wallpaper, we will deduct the amount paid for the sample of the chosen model.

In case of ordering several sample models, only the references that are ordered at the end are deducted).

What type of Alf&mabi wallpaper is it?

Our wallpapers are made on TNT (non-woven) backing: a washable, resistant paper with a grammage of 150 g/m2. This type of paper is made from natural fibres (cellulose) and synthetic fibres (polyester), which are bonded together in the production process to form a stable, tear-resistant product that is also breathable. Both characteristics make non-woven wallpapers extremely resistant to mould and mildew. This material has been the darling of the wallpaper market since it was launched in the 1990s and has many qualities in its favour. In addition to those already mentioned, there is also the ease of installation, as the glue is applied directly to the wall and not to the paper, thus facilitating the process. TNT wallpapers are washable (they can be cleaned with a damp cloth and neutral soap) and can be used in damp areas such as kitchens and bathrooms (always avoiding walls with direct and abundant contact with water and heat). Finally, when it is time to remove the strips, they come off without difficulty and leave no residue on the wall.


How are the wallpapers installed?

When you buy our wallpapers, you will find the installation instructions on the back of the inside label of the roll. The installation process is simple and similar to any other installation of TNT wallpaper, which is glued to the wall. In this video we show you the main tricks for a successful installation:

How easy is it to install wallpaper?
En general, en una pared entera, sin ventanas, puertas, radiadores, etc la instalación es bastante fácil y no se presentan apenas dificultades. La dificultad se puede incrementar cuando la pared presenta esquinas, ventanas, cajas de luz, radiadores, etc. En esta situación, hay que prestar especial atención y colocar el papel con mayor empeño y cautela.
Can I put wallpaper on stippled walls?

It is not advisable to put wallpaper on walls with stippled paint. Ideally, both for the best adhesion and for the finish of the wallpaper, the wall should be smooth, sanded and prepared with at least one coat of paint (preferably white, especially if you choose a wallpaper with a white background design).
Do I need glue for installation?

Yes, you will need glue for installation and this product does not come with the paper. You can buy the glue with your paper order directly from our website (to see the product click here) or buy it in hardware or DIY shops. The important thing is that it is a glue suitable for non-woven wallpaper or universal glues that are suitable for this type of wallpaper.

I need glue for installation?

Our wallpapers are certified B - s1 - d0 according to EN13501-1. Well, what does that mean? In short, it means that it is a low flammability wallpaper, that when it burns it feeds practically nothing to the fire. It is therefore a safe material for interiors.

Does the wallpaper remain yellowish on the wall after a while?

No, TNT wallpapers have a very good lightfastness: direct and permanent sunlight does not affect the visual effect of the material and does not fade its colours. What can cause the wallpaper to yellow over time is glue residue that has not been removed during the installation process. It is therefore very important to wipe off any excess glue between the strips with a damp cloth and soap as long as it has not yet dried.

Are TNT wallpapers moisture resistant?

TNT wallpaper is moisture-resistant and offers good protection against the growth of mould and mildew. It is a breathable material, permeable to air and vapour, i.e. a wall with TNT wallpaper is not sealed, in contrast to vinyl wallpaper, for example, which has a sealed surface that does not allow moisture to circulate freely between the wallpaper and the wall. For a humid area such as bathrooms, this feature is essential to avoid the danger of mould and mildew, although it is recommended that wallpaper should not be installed in areas of direct contact with water or heat.

Will removing the wallpaper destroy the wall?
Our wallpapers are made of non-woven backing, and one of their characteristics is that they can be removed from the wall in one go, strip by strip, without leaving any paper residue on the wall. But it can happen, yes, that when removing it some of the paint comes off with the paper, which can be solved with a bit of putty. In short, you may have to repaint the wall when removing wallpaper. The success of a residue-free removal depends on the glue used: it must be a glue that is suitable for TNT wallpaper and correctly prepared according to the manufacturer's instructions for each type of wallpaper. When using extremely sticky glues, the wallpaper may not come off the wall easily.

Do we have wallpaper installers?

Alf&Mabi does not have its own wallpaper installation service. Our recommendation is to find a painter you trust with experience in wallpaper installation. You should always provide them with the specific installation instructions for our wallpaper. These can be found on a QR code on the label or on the back of the roll label.
