[Comparative Example]

Concrete structures and steel structures were surface-treated by conventional methods, and after 24 hours of exposure, the primer and the EPOXY coating material were applied at a thickness of 300 μm and 72 μm, respectively, , Pinholes and surface roughness were found. As a result of the equipment measurement, the thickness of the coating film was not constant and the adhesive force was remarkably decreased to 6.5 N / mm. The elongation percentage was measured to be 49%. Conventional coatings are not easy to secure the quality because the thickness of the coating is not constant, and they do not correspond to the water expansion, and they are detached and peeled, thereby damaging the concrete structure and deteriorating the performance, resulting in a large maintenance cost.

However, when the adhesive sheet 100 for internal and external use of the present invention is applied to concrete structures and steel structures as in Examples 1 to 3, it was confirmed through visual inspection that no abnormality was found on the surface. The adhesive force was increased to 11 N / mm.

In addition, since the adhesive sheet 100 for internal and external use according to the present invention is excellent in waterproofing / damping effect and durability as described above, it can be used semi-permanently, and concrete structures and steel structures can be used for their original purposes. It is economically effective.
