To restore deteriorated masonry, MAPEI has developed POROMAP DEUMIDIFICANTE, single-product/single-layer mortar made from special salt-resistant, Pozzolan-reaction hydraulic binders, natural sand, lightweight aggregates and special additives with very low emission of volatile organic compounds (EMICODE EC1 R^Plus), according to a formulation developed in the MAPEI research laboratories.

The properties of POROMAP DEUMIDIFICANTE mortar, such as mechanical strength, modulus of elasticity, breathability and porosity, are very similar to those of mortar made from lime, lime-Pozzolan or hydraulic lime originally used in the construction of buildings, including those of historical interest. Compared with these types of mortar, however, POROMAP DEUMIDIFICANTE also has properties which make it resistant to the leaching action of rainwater and alkali-aggregate reactions, as well as to soluble salts often present in masonry and in the ground on which masonry is built.

Ideal for:

Internal and/or external macro-porous, dehumidifying and insulating render on stone, brick, tuff and mixed masonry, including recent builds, with capillary rising damp and saline efflorescence.
Dehumidifying render for masonry in lagoon areas or close to the sea.
Dehumidifying render on stone (such as limestone) and/or particularly porous, absorbent brick masonry, and in general wherever there is saline efflorescence.
Pointing "exposed-finish" stone, brick and tuff masonry.
Certified comfort. Ideal for your wellbeing.

 Restoring the walls of your home to counteract discomfort caused by damp. The product is certified EC1 R Plus (very low emission of volatile organic compounds) and formulated while focusing on the health and safety of those who use and apply the product and of those who inhabit the rooms where it is applied.
