HG ornamental plaster cleaner makes unpainted, dirty ornamental patch very fast and well clean. It easily removes moisture deposits from grease, soot, nicotine etc. Overcoating becomes unnecessary.
Clear the room beforehand. Cover all untreated surfaces with cover foil. Make the surface dust-free with a soft brush. Pour HG ornamental cleaner in a paint roller bin. Roll in with a paint roller until foam develops. Roll the surface thinly and evenly. Remove excess foam with a damp cloth. Rinse or after-treatment with water is not necessary. After about 3 hours the surface is dry.
