Frequently Asked Questions

What material is your wallpaper made of?

The wallpaper is heavy, high-quality, solid vinyl. This design is printed on top quality solid vinyl wallpaper with a beautiful matte, paper look. Solid Vinyl wallpapers are more durable and able to be washed off which is ideal for highly frequented areas. Not sure about the colour? We recommend you order a wallpaper sample first to experience the colour and ensure that it meets your expectations.

The mural design circle is printed on top quality non-woven (165 gm, extra matte) wallpaper with a beautiful matte, paper look. The great thing about non-woven wallpaper is that it is easy to apply and also easy to remove.

What is the difference between patterned wallpaper and wall murals?

Patterned wallpaper features a specific pattern repeated in height and width.

The term wall mural refers to all wallpaper that features a single image (i.e. not a repeatable pattern). It is wall-filling (from floor to ceiling) wallpaper. It is available in standard sizes. If you require another size, please order customized wallpaper.

Calculate, hang and remove wallpaper

How many rolls of wallpaper do I need?

Measure your wall first. Then add an extra 6 cm in width and 106 cm in height for cutting loss.

Suppose you have a wall 342 cm wide by 262 cm high. Including the cutting loss, the required size is 348 x 268 cm.

A Unicolor Linen collection wallpaper roll is 53 cm wide and 10 meters long. If your wall is lower than 250 cm, you get exactly four strips from one roll. If your wall is between 251 and 333 cm high, you get three strips from one roll.

Suppose you have a wall 297 cm wide by 265 cm high. Including the cutting loss, the required size is 307 x 275 cm. With this height, you get three strips from one roll. Now, divide your wall width by the strip width: 307: 53 = 5.79. Let’s round them up to 6 strips. So in total, you need two wallpaper rolls. The batch number on the roll shows from which print run the wallpaper comes. When you order multiple rolls, the rolls must have the same batch number to avoid small colour differences. Therefore, it is essential always to check whether the supplied rolls are from the same printing run before hanging the wallpaper.

Is it difficult to hang wallpaper?

No, on the contrary, it’s very easy. You don’t even need a wallpaper table. First, cover your wall with glue. Then apply the dry wallpaper strips. On each roll, you will find a step-by-step application instruction (in English).

What type of wallpaper glue do I need?

For all our wallpaper, we recommend Perfax Ready & Roll glue for non-woven wallpaper. This is a ready-to-use wallpaper glue. Apply it directly to the wall from a bucket with a large paint roller. The glue is available at any hardware store, do-it-yourself store or wallpaper store. You can use wallpaper glue from another brand, as long as it is non-woven wallpaper glue (not for paper wallpaper or vinyl wallpaper glue).

How do I hang a wallpaper circle?

Unlike the ‘normal’ non-woven wallpaper (such as patterned wallpaper or wall mural), you do coat the wallpaper with non-woven wallpaper glue. There is no exposure time, and you can hang the wallpaper circle or panel straight away. Glue dries up within ten minutes, which gives you plenty of time. You’ll find the application instructions are on the wallpaper label (in English). You can also find these on the Contact page (Application instructions).

How can I remove wallpaper?

Removing non-woven wallpaper is very easy, and you don’t require a steamer. Even after several years, you still can pull the wallpaper strips from the wall. However, do this carefully as pieces of wallpaper may not come off straight away. A piece of wallpaper left on the wall? Carefully cut it off with a clean putty knife so that the wall becomes smooth and you can hang new wallpaper.
