スキング材(3)を自重により自然脱離させる。Conventionally, as this type of masking material, there has been provided a structure in which an adhesive layer (3) B is provided on one surface of a panel-shaped body (3) A made of a plastic foam as shown in FIG. The masking material (3) having such a structure is adhered to the surface (2) of the member, such as an automobile floor panel (1), which should not be surface-treated, through the adhesive layer (3) B. After that, apply surface treatment such as painting. Thus, as shown in FIG. 10, for example, in the case of coating, a coating film (4) is formed, but since the predetermined surface (2) of the floor panel (1) is covered with the masking material (3), the coating film (4) is formed. (4) is not formed. Then, the masking material (3) is softened and shrunk by heating, for example, in a coating and baking process, and the masking material (3) is naturally detached by its own weight as shown in FIG.

である。In the above conventional technique, after the surface treatment, the masking material (3)
Masking material when softening and shrinking to allow natural desorption
It is necessary to break through the surface-treated film (4) covering (3), but a surface-treated film such as a coating film having a relatively high strength is difficult to break through, which is a serious obstacle to the natural detachment of the masking material. Furthermore, when the masking material (3) is attached to the surface (2) which should not be surface-treated, the masking material (3) does not have an appropriate handle portion, so that adhesion is difficult.
