Muro K Idro
Water-repellent remediation mortar for damp masonry, based on natural hydraulic lime.
Water-repellent mortar for restoring and drying out masonry damaged by rising damp and water-soluble salts. It offers controlled shrinkage and high mechanical performance, high workability, thixotropy, plasticity and elasticity, and a low content of water-soluble salts; it does not react with salts in the masonry, has a very low VOC content and is fully recyclable at end of life. Based on NHL 3.5 natural hydraulic lime, pozzolanic materials and pure selected aggregates with a maximum grain size of 3 mm, it is ideal for restoring existing masonry, especially in listed buildings, damaged by rainwater or rising damp.
Key features:
- contains no Portland cement;
- contains no resins or organic additives that release VOCs;
- class CS IV according to UNI EN 998-1;
- freeze-thaw resistant;
- adds no water-soluble salts to the masonry;
- does not react with any sulfates in the masonry, so it is compatible with historic masonry;
- breathable and hygroscopic, it prevents mold and condensation and regulates indoor humidity;
- reversible and compatible with historic masonry;
- fully recyclable at end of life.
Muro K Idro can be used as a dehumidifying plaster on solid brick, mixed stone, brick, concrete, sand-cement block, tuff or calcarenite masonry wherever the repair product must offer high breathability, chemical inertness and a low content of water-soluble salts to make the work effective and durable, and wherever the condition and function of the existing plaster are compromised by rising damp or capillary absorption.
Muro K Idro is highly breathable and water-repellent and is particularly suitable for protecting the lower part of walls from rainwater or standing water.
Its extremely low content of water-soluble salts reduces the risk of salt efflorescence and of the finishes on the treated walls becoming unsightly and/or coming away.
The main applications are summarized below:
- Dehumidifying plaster on indoor or outdoor walls;
- Exterior plaster protecting weather-exposed walls from rainwater;
- Weather-protective capping on top of stone or solid brick walls;
- Damp-proof plinth preventing rising damp in thermal renovation work with insulating plaster or absorbent insulation boards.
