  When the base of the base plate of the wall or ceiling is subjected to base processing, the putty agent for base preparation adheres to the joint of the base plate, and after the drying shrinkage, further adheres to the finish. After the drying shrinkage, the surface of the putty agent is smoothed with a sander. Groundwork adjustment with putty agent takes a lot of work.

  The smoothened surface of the base adjustment putty agent is hard to adhere the paste for decorating paper or cloth for decoration, and adhesion of the paper or cloth for decoration is not sufficient. Moreover, the paint for cosmetics is hard to adhere to the smooth surface of the base preparation putty agent.

  A mesh-like tape such as the joint covering tape disclosed in Patent Document 1 does not use a putty agent for adjusting the base, and is applied to both sides of the joint across the joint of the base plate, and wallpaper or wall cloth is applied thereon. When pasted, the wallpaper or wall cloth may float or sink at the part of the mesh of the mesh tape.

  Also, if the tape with adhesive applied to the entire surface of one side is bonded to both sides of the joint across the joint of the base plate, the width of the joint of the base plate may increase or decrease, or the base plate may become uneven. May be damaged.

  The cover material with legs such as the joint cover material disclosed in Patent Document 2 cannot be used for joints narrower than the legs. In addition, when the legs of the cover material are inserted into the joints of the base plate, the amount allowing the base plate to extend becomes narrow.
