ElastoKappa RA

Special rapid two-component elastic mortar, fast-drying even at low temperatures or on substrates that are not perfectly dry, 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 RA is ideal when the waiting time between applying the waterproofing and continuing work on site needs to be reduced.

It is suitable for:

• waterproofing foundation and above-ground 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 RA offers:

• fast setting and hardening, even at low temperatures or on substrates that are not perfectly dry;
• tiling 4 h after application, or after 24 h at low temperatures;
• 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 RA meets the principles of UNI EN 14891 (liquid-applied waterproofing products for use beneath ceramic tiling bonded with adhesives).
