Prepacked light coloured cement-free “salt-resistant” mortar to be applied before: Mape-Antique MC, Mape-Antique CC, and Mape-Antique LC dehumidifying mortars on stone, tuff and brick substrates. Mape-Antique Rinzaffo is especially recommended for use as a first coat in the restoration of old stone, tuff, and brick period buildings damaged by the strong presence of chlorides. It is especially recommended to improve the adhesion and chemical/physical resistance to soluble salts of macro-porous mortars such as Mape-Antique MC, Mape-Antique CC, and Mape-Antique LC dehumidifying mortars. Mape-Antique Rinzaffo special properties prevent soluble salts from penetrating macro-porous mortars. The hygroscopicity of soluble salts such as chlorides can cause localised humidity in mortars used in insufficiently ventilated areas. To prepare, mix a 20 kg bag of Mape-Antique Rinzaffo with 5 to 5.5 l of water in an ordinary job site mixer for 5-6 minutes. Mape-Antique Rinzaffo is applied by trowel or by spray on a previously prepared substrate in a maximum thickness of approx. 5 mm. Consumption 7.5 kg/m2 per 5 mm of thickness. Packaging 20 kg bags.
