Cleaning historic buildings can sometimes be just as complex a task as restoring them – especially when dealing with large-scale cleaning operations that have to be carried out while the building is still in use. Arte Mundit is a special product that gently cleans interior surfaces by removing dust, soot, fire residues and other impurities. This natural-rubber-based, self-vulcanising cleaning paste can be applied by a brush or roller, as a slurry, or using airless or airmix sprayers. Not only does the process use very little water, but the product itself is also free from organic solvents, surfactants and inorganic salts. The result is a gentle cleaning action that does not damage the building. Arte Mundit boasts an impressive list of references that spans a wide range of historic buildings and listed monuments. Notable examples include the National Capitol Building in the Cuban capital of Havana, and London’s historic Westminster Hall.
