Water repellent mortar for the rehabilitation and dehumidification of walls damaged by capillary rising of water and the presence of water-soluble salts, with controlled shrinkage and high mechanical performance, high workability, thixotropy, plasticity and elasticity, low content of water-soluble salts, not reactive in the presence of salts in the masonry, of very low VOC content and completely recyclable at the end of life, based on natural hydraulic lime NHL3,5, pozzolanic materials, selected pure aggregates with a maximum particle size of 3 mm, ideal for interventions recovery of existing walls, especially if subject to protection, damaged by the presence of meteoric water or capillary rising.
Summary of characteristics:
Wall K Idro can be used as a dehumidifying plaster on walls in solid brick, mixed stone, brick, concrete, sand and cement blocks, tuff or calcarenite, in all the cases in which high characteristics of breathability, chemical inertness and low content of water-soluble salts of the product to be restored are required to guarantee the effectiveness and durability of the intervention and in which the state and functionality of the existing plaster is adversely affected by the presence of water for ascending or capillary absorption.
Wall K Idro is highly breathable and water repellent and is particularly indicated for the protection of the lower part of the wall from rainwater or stagnation water.
The extremely low content of water-soluble salts allows to reduce the risk of formation of salt efflorescence and of the phenomena of aesthetic degradation and / or detachment of finishes on the walls on which it is applied.
The main fields of application are summarized below:
