Ready-to-use mortar based on natural hydraulic lime for smoothing rough plasters in accordance with (GP)(CS III W1) UNI EN 998-1.
The new formula of our lime-based smoothing compound, totally free of pozzolanic materials, blast furnace slag, fly ash or hydraulic binders of any nature (clinker, cement, etc.), is made up of hydrated mono and dicalcium silicates, specific wetting agents, inert with controlled grain size and additives promoting adhesion and workability.
Product features
The use of Pure Natural Hydraulic Lime NHL 5 as the sole binder for the production of mortars and plasters makes these products biocompatible, fully respecting man and the environment. The total absence of salts, chemical products and volatile organic compounds, combined with the total mineral nature of the components, guarantees purity, non-toxicity, non-harmfulness and complete recyclability.
The peculiar characteristics of Pure Natural Hydraulic Lime NHL 5, such as the slow hardening process, the continuous increase in mechanical resistance over time, combined with a low elastic modulus, give elasticity to the products made with it, differentiating them from those made with products lime or cement based.
The use of NHL 5 allows you to operate in perfect affinity with the rules of the ancient art of building typical of Restoration as well as Green Building.
The porosity of NHL 5 Natural Hydraulic Lime guarantees high diffusion of water vapor, gives breathability to the support, allows the disposal of absorbed water and regulates environmental humidity, avoiding the formation of harmful condensation and mold. The high basicity of the mixture, whose pH is equal to 12.5, makes the surfaces resistant to biodeteriogenic agents and avoids their proliferation, creating conditions hostile to the survival of pathogenic microorganisms (bacteria, fungi, viruses) causing infections, diseases or allergic reactions.
The products obtained with the NHL 5 binder alone, being totally mineral, do not constitute “special waste”.
Fields of use: rapid and quick smoothing of rough or partially degraded plasters, concrete, block or expanded clay planks, dehumidified walls with macroporous plasters such as our SIRIOBETON IDR.
Advantages: easy and quick application and finishing on all supports, mainly in very thin thicknesses (1-2 mm) without highlighting problems of rapid evaporation of water; high breathability and excellent adhesion to the support; high degree of finish: it can be left as is or painted with highly breathable paints; valid aesthetic solution of uniform white colour.
