Repairs to masonry deteriorated by the disintegrating action of concentrated salts. Rebuilding old lime-based render deteriorated by the action of atmospheric agents and environmental conditions or by ageing. New transpirant and “structural” render on weak or particularly difficult masonry. Some application examples Mape-Antique Rinzaffo must be used as the first layer for: • nternal and/or external macro-porous, de-humidifying i render on walls with capillary rising damp. • e-humidifying render on stone, brick, tuff or mixe

mixer, Mape-Antique Rinzaffo forms a salt-resistant, transpirant scratch-coat mortar with a semi-fluid consistency which is easy to apply by trowel or with a rendering machine on both vertical surfaces and ceilings. When used as the first layer for de-humidifying, transpirant and “structural” render, Mape-Antique Rinzaffo improves the bond, even out the absorption of substrates and slows down the transfer of salts. The properties of mortar made using Mape-Antique Rinzaffo, such as mechanical strength, modulus of elasticity and porosity, are very similar to mortar made using lime, lime-pozzolan and hydraulic lime originally used in the construction of old buildings. Compared with these types of mortar, however, Mape-Antique Rinzaffo also has properties which make the product resistant to various chemical-physical aggressive phenomena, such as the presence of soluble salts, freeze-thaw cycles, the leaching action of rainwater, alkali-aggregate reactions and the formation of cracks c

aused by plastic shrinkage. When working on particularly damp internal walls or in cold weather, the setting and hardening times of Mape-Antique Rinzaffo are considerably longer and much more time than usual must be allowed for the product to cure. The product may give off a different odour for a while when curing under such conditions [Risanamento murature] 607_mape-antique rinzaffo_gb (4) (18.05.2015 - 3ª Bozza/Ciano/PDF) e iquffo t -An nza i pe R Ma Brick wall after removing the deteriorad render Preparation of Mape-Antique Rinzaffo Application of Mape-Antique Rinzaffo and may turn green in some areas.
