We recommend that you only wallpaper on smooth surfaces. This is because coarse walls will be visible through the wallpaper and the adhesive will not adhere as well. There is also a chance that air can get underneath the wallpaper so that the seams will become more visible.

Online, the number of square meters (m2) is automatically calculated based on the width and height of the wall. It is important that the measurements are correct. Therefore, always measure in different places. Width The width: at the top from left to right and at the bottom from left to right. Height The height: upper left to the bottom, upper middle to the bottom and upper right to the bottom. Walls can always be skewed, especially in old houses. That's why we recommend adding 2 inches on all sides of the wall, so you won't be running out of wallpaper.
