A system and method for detecting, marking and/or sealing building envelope leaks in buildings or any enclosed structure. Fogs of aerosolized sealant particles that have a surface tackiness that diminishes over time are introduced into the interior of prepared rooms. The surface properties of the aerosol particles can be controlled with the selection of sealant composition, including the presence and concentration of solvents, the range of produced particle sizes, and the relative humidity and temperature within the enclosure. A pressure differential is created and the micron scale particles adhere to the leak edges and to other particles as they are brought to the leaks and then leave the gas streamlines. Control of particle size, drying rate and particle residence time in the building interior allows control over the treatment area so that leaks are sealed without leaving a tacky residue.
