Title: Method for finding leak in the roof and liquid agent or paste being employed therein
Inventor: KUWAHATA KATSUHIKO
IPC: G01M3/38
Filed: 1998-09-17
Abstract: PROBLEM TO BE SOLVED: To find out leak in the building easily by coating an estimated leaking part with water soluble solution containing fluorescent dye or pigment from the outside of the building and then discharging water toward that part. SOLUTION: An estimated leaking part is coated with water soluble liquid containing fluorescent dye or pigment from the outside of the building and then water is discharged toward that part. When rain leaks from a part inserted with the fluorescent dye, discharged water permeates into the building while dissolving the fluorescent dye or pigment. When UV-rays are irradiated, the fluorescent dye or pigment is excited to emit fluorescence. It is substantially invisible in a bright place but can be recognized easily in a dark place, e.g. a garret. Since condensate contains no fluorescent dye or pigment and emits no fluorescence, it can be distinguished clearly from leaking rain.
