Prepacked salt-resistant mortar to be applied before the dehumidifying and thermal insulating render PoroMap Intonaco.
PoroMap Rinzaffo is used as a primer for the repair of stone, brick, and tuff buildings damaged by capillary rising damp. It is a prepacked powder mortar composed of special hydraulic binders with pozzolanic reaction and is highly resistant to sulfates, consisting of natural sand and special additives.
It is a slightly fluid mortar once mixed with water and is workable on vertical surfaces and ceilings. It is especially suitable for improving the adhesion and chemical/ physical resistance to soluble salts of macro-porous dehumidifying mortars. Its special properties prevent soluble salts such as chlorides, sulfates and nitrates from penetrating the macro-porous mortar. The hygroscopicity of these soluble salts can cause localised humidity in mortars used in insufficiently ventilated areas.
Due to PoroMap Rinzaffo's composition and despite its high porosity, it is so durable as to make it virtually indestructible when attacked by various aggressive natural phenomena: freeze-thaw cycles, alkali-aggregate reaction and attack of sulphate salts, nitrates and chlorides that are often in masonries and in soils on which they are built.
