摘要

The invention relates to a process for the treatment of deteriorated external surfaces of old stonework and masonry caused by micro-organisms and vegetation growth. According to the invention, the process consists, in a first stage, in spraying a curative 10% biocidal solution consisting of 0.7...14% synthesis biocides with sporicidal, bactericidal and fungicidal effect, preferably glutaraldehyde and quaternary ammonium salts, or 15...35% fatty acid derivative with non-selective herbicidal effect and 0.5...3% azolic fungicide, 0.1...5% aromatic oil, 5...80% solvent, 0.5...10% emulsifier and, for the remainder up to 100%, water, removal, after 10...25 days, of the so destroyed bioderm, washing and drying the surface and uniformly applying by spraying or brushing a preventive biocidal composition comprising 0.5...5% peroxidic fatty acid derivative or 0.5...6% quaternary ammonium salt and fungicide, 0.5...5% bioactive essential oil and 60...90% biodegradable air-drying film-forming agent.
