あった。[0003] For the airtight structure of such fumigation warehouses, the use of a rubber-asphalt emulsion has been generally proposed (Japanese Patent Publication No. 58-41107). However, since the rubber-asphalt emulsion needs to be sprayed as an aqueous solution, the construction is carried out. There was a problem in that curing (drying) took a long time.

(Japanese Patent Publication No. 7-116762). Although this construction method can completely secure airtightness against poison gas, it has a tendency to take a long time to cure and to take a long work period because rubber-asphalt emulsion is still used.

The coating can be performed by hand coating with a brush or a trowel, or by spraying with a sprayer. Spraying with a sprayer is preferred for efficiently and uniformly applying a large amount over a wide range. For curing drying, natural drying and drying with a fan are possible. If the coating is too thick, curing and volatilization of the solvent are delayed, causing swelling. Therefore, it is necessary to always pay attention to the coating thickness.
