The joint of plasterboard walls with the same suspended ceiling, even the most carefully puttied one will crack and crumble. This is due to the unavoidable movements of the ceiling tiles due to the occurring vibrations. The way to avoid this is to do the so-called. moving weld. In this method, stick tape to the side wall at the height of the ceiling. After applying the putty, the putty will not stick to the tape and there will be a minimal gap at the joint, very slightly visible.
