There should be no gaps between neighboring panels.

Next, the installation of the elements that will hold the panels should be followed. When lining the wall to the ceiling, it is necessary to mount the ceiling plinth. The first panel is mounted with a narrow part of the fasteners in the groove at the mount. Constantly check that the panels are strictly perpendicular to the floor planes using a plumb line with a level. After you checked this, you need to fix the mounting shelf with nails or metal brackets. Using this shelf, attach the subsequent plastic panels in the groove already installed structural elements. There should be no gaps between neighboring panels. Even a small distance between the panels must be avoided. After these actions, the panel should be fixed. Subsequent elements are mounted in the same sequence, with the exception of the last panel. It should be shortened by 6 millimeters of the side where the mounting regiment is attached. And then it is inserted into the grooves. The last panel does not need to be fixed in addition to other types of mounts. In the grooves, she should hold on reliably and tight.
