ElastoKalce iSi

Special one-component polymer-modified mortar based on NHL 3.5 natural hydraulic lime, water-reducing admixtures, rheology modifiers and pure selected very fine aggregates, for flexible skim coats that are impermeable to water, salts and carbon dioxide, with high bond strength on historic concrete, natural hydraulic lime or hydraulic binder plasters and screeds, brick, solid brick, tuff or mixed stone masonry, terracotta tiles, ceramic or stone slabs, fiber cement, gypsum fiber, plasterboard, marine plywood, wood fiber, Plywood, OSB (type 3 - 4), aerated concrete panels and the like, applied by trowel, brush or roller. Thanks to its advanced mix design, the cured product remains elastic and deformable even at temperatures well below freezing, is not degraded by de-icing salts, chlorides, nitrates, sulfates or carbon dioxide, and bonds excellently to all the substrates it is recommended for.

ElastoKalce iSi can be applied with a float or steel trowel, or with a brush or roller, simply by changing the amount of mixing water. This makes it extremely easy and versatile to apply, and suitable for all wall surfaces, plastered or not, even uneven ones (for example unplastered exposed masonry).

ElastoKalce iSi can be used to:

• protect lime, natural hydraulic lime or hydraulic binder plasters from the weather;
• waterproof wall bases and plinths in mixed stone, tuff or solid brick;
• waterproof and protect foundations in mixed stone, tuff or solid brick;
• waterproof and protect solid brick or stone wall copings;
• waterproof brick roof decks or sloped screeds under roof tiles;
• waterproof and protect existing lime or lime-and-cocciopesto screeds exposed to the weather;
• apply a protective layer against rising damp on existing subfloors or screeds, to protect the new flooring;
• apply a damp-proof course between the subfloor and the first course of perimeter walls or partitions;
• waterproof balconies, bathtub surrounds, shower walls and terraces before tiling;
• waterproof terracotta, ceramic or stone coverings on terraces or balconies;
• waterproof and protect plasterboard, gypsum fiber, fiber cement, marine plywood, wood fiber, Plywood, OSB (type 3 or 4), aerated concrete panels and the like.

ElastoKalce iSi offers:

• very high elasticity, even at low temperatures (down to -20 °C);
• very high bond strength;
• very low carbon dioxide permeability;
• UV resistance;
• resistance and impermeability to salts.

ElastoKalce iSi, although based on NHL 3.5 lime, meets the principles of UNI EN 14891 (liquid-applied waterproofing products for use beneath ceramic tiles bonded with adhesives).
