ElastoKappa

Highly flexible, high-bond waterproofing coating.

Special two-component mortar based on hydraulic binders, pure selected fine-grained aggregates and water-dispersed polymers, for flexible skim coats that are impermeable to water, salts and carbon dioxide, with high bond strength on concrete, plasters, cement screeds, brick masonry, ceramic or stone tiles and slabs, fiber cement, gypsum fiber, plasterboard, marine plywood, wood fiber, aerated concrete panels and the like. Thanks to a special emulsion, the hardened 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.

ElastoKappa is suitable for:

  • waterproofing concrete and protecting it from absorbing water, salts and carbon dioxide;
  • waterproofing and protecting hydraulic binder plasters;
  • waterproofing and protecting plasterboard, gypsum fiber, fiber cement, marine plywood, wood fiber, aerated concrete panels and the like;
  • waterproofing wall bases in mixed stone or solid brick;
  • waterproofing and protecting wall copings or brick roof decks under roof tiles;
  • waterproofing balconies, bathrooms, showers and terraces before tiling;
  • waterproofing ceramic or stone coverings on terraces or balconies.

ElastoKappa 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.

ElastoKappa meets the principles of UNI EN 14891 (liquid-applied waterproofing products for use beneath ceramic tiling bonded with adhesives).

ElastoKappa is used to waterproof vertical structures (e.g. below-grade walls) or horizontal ones (e.g. balconies or terraces before tiling) under positive or negative pressure, made of concrete substrates, tanks or slabs, sand and cement screeds, hydraulic binder blocks or plasters, plasterboard, fiber cement, marine plywood and similar panels that need protecting from water absorption or seepage.

ElastoKappa forms a protective layer that is impermeable to water and carbon dioxide and resistant to de-icing salts. It makes the substrate it is applied to freeze-thaw resistant and extends its service life. It is ideal for protecting terraces and balconies, and concrete or hydraulic mortars in general, to increase their durability or bring it in line with their exposure class.
