Pre-mixed, salt-resistant mortar to be machine-applied prior to application of F.78 MUROSAN LIGHT RISANA insulating and dehumidifying plasters. Semi-fluid consistency.

Easily workable on both vertical surfaces and ceilings. Improves adhesion and chemical-physical resistance to the soluble salts of macro-porous dehumidifying plaster.

F.78 MUROSAN LIGHT RINZAFFO must be used as a first layer, applied by machine straight onto clean masonry after the old plaster has been removed and before application of F.78 MUROSAN LIGHT RISANA, in the following cases:
• Application of dehumidifying plasters on masonry strongly affected by rising damp.
• Application of dehumidifying plasters on the indoor and outdoor walls of buildings, of even recent construction, affected by rising damp.
• Application of dehumidifying plasters to the masonry of structures situated in lagoon areas or near the sea.
• Application of dehumidifying plasters on walls in stone, bricks and tuff.
• Creation of new dehumidifying plaster surfaces on structures made of stone (especially porous types, like limestone) and/or bricks, even when not properly fired (e.g. walls, pillars, vaults, etc.) and whenever saline efflorescence is a problem.

For indoor and outdoor use.
