A method for establishing and maintaining a microbiologically clean environment in a room by painting at least its wall and ceiling surfaces with a porous layer formed of a porous material, such as perlite, zeolite or micronized silicon dioxide, optionally mixed with a fungicide or bactericide, then repeatedly spreading an aqueous liquid mixture containing a sanitizer over the porous layer, the water in the aqueous liquid mixture being evaporated between each application, leaving sanitizer in the pores of the porous layer. |
