好ましい厚み条件を容易に設定することができる。Following the masking process, as shown in Figures 2 and 2-a, joints are made around the entire circumference of the masking member (2) and the entire crack to be repaired (1), excluding the masking part (11). Provide a stop (4). The material may be either organic or inorganic, but organic materials have some problems with workability during peeling, so inorganic materials, such as those whose main component is cement mortar, are suitable. Seal joints using cement mortar-based materials (4)
When forming a joint, use a relatively thick wall, for example 2 to 10 mm, to prevent the joint seal (4) from breaking into small pieces when peeled.
It is preferable to form it to a certain degree of thickness. For joint sealing work, use a masking material (2) with a certain thickness.
Since it serves as a gauge, it is easy to adjust the thickness of the joint (4) to a constant thickness, and it is also possible to easily set a preferable thickness condition for subsequent removal work.
