Method for sealing inorganic substrate i.e. water bearing substrate, involves atomizing sealing material in spraying equipment by supplied pressurized air and supplying reaction accelerator to sealing material by pressurized air

摘要

The method involves conveying a sealing material as a wet stream in a spraying equipment (26), where the sealing material in the spraying equipment is atomized by supplied pressurized air. The sealing material is supplied by nozzles (24) to a substrate to be sealed. A reaction accelerator is supplied to the sealing material by the pressurized air. The sealing material is used as a sealing mortar. The sealing material is accelerated with the reaction accelerator before entering the spraying equipment. The reaction accelerator is added in form of aqueous solution. An independent claim is also included for a device for sealing an inorganic substrate.
