As a result, it was found that a certain level of waterproofing effect was obtained even if surface peeling or blistering occurred in a short-term watering.In addition, it was found that the rebar had a tendency to corrode when the coating film crack and the crack reaching the rebar occurred in the skeleton, but the corrosion could be suppressed by the repair which requires less process.
