po ac Ma roon o t P In EN 998-1 IN COMPLIANCE WITH EUROPEAN STANDARD EN 998-1 R-CS II RENDERING AND PLASTERING MORTAR Salt-resistant, macro-porous de-humidifying and insulating render, based on hydraulic pozzolanic-reaction binder, to be used by hand for renovating masonries deteriorated by the presence of rising damp and soluble salts WHERE TO USE Renovating brick, stone and tuff masonry, including recent builds, damaged by capillary rising damp. Renovating masonry damaged by the crumbling effect of sulphates, chlorides and nitrates. Some application examples • Internal and/or external macro-porous, de-humidifying and insulating render on stone, brick, tuff and mixed masonry, including recent builds, with capillary rising damp and saline efflorescence. • De-humidifying and insulating render on stone (such as limestone) and/or particularly porous, absorbent brick masonry, and in general wherever there is saline efflorescence. • De-humidifying and insulating render for ma

sonry in lagoon areas or close to the sea. • Repairing damaged render on buildings built using low performances mortar. • Pointing between stone, brick and tuff elements on “exposed” masonry. TECHNICAL CHARACTERISTICS PoroMap Intonaco is a ready-mixed powdered mortar for macro-porous, de-humidifying and insulating render made from special hydraulic, pozzolanic-reaction binders, natural sand, lightweight aggregates and special additives with very low emission of volatile organic compounds (EMICODE EC1 R Plus) according to a formula developed in the MAPEI research laboratories. This product is classified as R according to EN 998-1 Standards: “Renovation mortar. Mortar designed for internal/external render applied on damp masonry walls containing water-soluble salts”, Category CS II. When mixed with water in a cement mixer, PoroMap Intonaco forms a salt-resistant, macro-porous, de-humidifying and insulating rendering mortar with a plastic-thixotropic consistency which is ea

sy to apply by trowel both on vertical surfaces and ceilings. The properties of a mortar made using PoroMap Intonaco, such as mechanical strength, modulus of elasticity and porosity, are very similar to those of a mortar made using lime, lime-pozzolan or hydraulic lime originally used in the construction of old buildings. Compared with these types of mortar, however, PoroMap Intonaco also has properties which make it resistant to acid rain, freeze-thaw cycles, the leaching action of rainwater, alkali-aggregate reactions and soluble salts often present in masonry and in the ground on which the masonry is built. Typical values are shown in the Technical Data table (see Application Data and Final Performance sections) which refer to the main characteristics of PoroMap Intonaco at both the wet and hardened states. RECOMMENDATIONS • Only apply PoroMap Intonaco after applying a layer around 5 mm thick of PoroMap Rinzaffo. • Apply PoroMap Intonaco in layers at least 20 mm thick. • Do

not apply PoroMap Intonaco with a rendering machine (use PoroMap Intonaco Macchina). • Do not use PoroMap Intonaco for pouring into formwork. • Do not use PoroMap Intonaco to make “reinforced” render. p Ma co oroona P Int Application of PoroMap Intonaco by trowel Application of PoroMap Intonaco by trowel • Do not use PoroMap Intonaco for skimming (use PoroMap Finitura). • Never add additives, cement or other binders (lime and gypsum) to PoroMap Intonaco. • Do not apply thin coats of coloured paint or coating products which could affect the transpiration properties of PoroMap Intonaco and, therefore, obstruct the evaporation of moisture in the masonry. Use products from the Silexcolor or Silancolor ranges, lime-based paint or water-repelling products such as Antipluviol S or Antipluviol W. • If the structures to be renovated have a high level of capillary rising damp and high concentrations of soluble salts, we recommend forming a horizontal chemical barrier
