1. Prepare the wall
You need to make sure that the wall is perfectly smooth, without any bumps or holes; in case there are any holes, you will have to fill them to make the surface ideally flat and smooth. It also must be able to absorb moisture, otherwise the drying process will be very slow, and the photomurals might not stick to the wall well enough. Your wall also needs to be perfectly clean, especially from any grease, such as the grease that remains after using an oil-based wall paint, so good cleaning is also very important.
Lay out the wallpaper before hanging and check if all is in order.
4. Draw orientation lines
Your sheets need to be positioned at right angles, so in order to be able to have a good orientation, you should take a pencil, water level, and plumb-bob, and draw one perfectly horizontal line, and one perfectly vertical line. Start the lines from the middle of the wall borders, so they would intersect at the center of the wall (like a cross, or a plus symbol).
5. Apply the paste
First, you need to prepare the paste. Any regular commercial wallpaper paste will do and you have it included in the package; prepare it simply by following the instructions printed on the bag. Lay the sheets on the floor face down. Do not let them overlap and do not put them onto each other. Apply the paste carefully and evenly. Cover the whole sheet, including the edges (especially the edges). Cover only one sheet and then proceed to the next step. If you apply paste to all sheets at once, paste will dry off before you apply all the sheets to the wall.
After applying the paste, leave the sheet on the floor for 3-5 minutes, so the sheet soak up some of the paste. That will help them bind to the wall much stronger.
6-7. Apply the sheets to the wall
You should start from the middle. So, take sheet 4 and press it against the wall, following the drawn lines as guidelines. Apply the pressure to the sheet, slowly working your way from the top to the bottom, and from the center of the wall towards the edge. Be sure to press the sheet tightly to the wall, and do not let any air remain between the wall and the sheet. Then apply sheets 6, 2, 8, and 3, 5, 1, 7.
Furthermore, since the sheets might shrink a little after they dry off, you would have to overlap them for couple of millimeters.
8. Let the sheets dry off
You do not want the sheets to dry off quickly. If that happens, they might shrink too much, ripping the edges of the sheets, or retracting and leaving empty spaces between them. The ideal conditions that will slow down drying require relatively low room temperature (20 degrees Celsius, or couple of degrees lower) and slow circulation of air through the room. That can be accomplished by not heating the room too much, and by making sure that there is no draft – by keeping doors and windows closed.
8. Cut the edges
Only after the sheets have dried off, take the carpet knife, and cut off any excess edges. You do not need to worry about cutting the edges disrupting the visual appeal of the photomural, because all our photomurals are designed in a way that any of the sheets border could be cut off without disrupting the visual effect of the photomural as a whole.
