Kerakoll Nanodefense Eco is a certified, eco-friendly, organic, water-based, mineral waterproofing membrane for absorbent substrates in damp environments, ideal for use in GreenBuilding.
It is a single-component with very low volatile organic compound emissions that safeguards the health of both operators and the environment. Kerakoll Nanodefense Eco develops total water-resistance under positive thrust guaranteeing the protection of absorbent substrates or those subject to damp, or in constantly humid environments.
Kerakoll Nanodefense Eco is used for waterproofing smooth, compact and absorbent substrates before laying ceramic coverings with adhesives.
– gel adhesives, mineral adhesives and mineral adhesives with SAS technology
– single-component and two-component organic mineral adhesives
– cement-based, water-dispersed, reactive-epoxy and polyurethane two-component adhesives
Kerakoll Nanodefense Eco is for internal use only, suitable for use on: Concrete flooring, compact and smooth cement-based screeds, prefabricated or fresh concrete castings, gypsum, plasterboard and gypsum brick walls, cement-based plasters and finishing products and cement-lime mortar.
Do not use in external applications, on wet surfaces or substrates subject to moisture rising; in environments where water is always present, baths, swimming pools and tanks.
Kerakoll Nanodefense Eco is supplied ready for use. Before use it is advisable to remix the product inside the container to ensure the mixture is of an even consistency. Any excess adhesive can be kept for later use by sealing the container. Apply a fine, uniform film, preferably using a roller, a steel spreader or a brush. Repeat the operation when the first coat has hardened (≈ 1 hr according to the absorbency of the substrate and the temperature).
The distinct light blue colour of Kerakoll Nanodefense Eco allows the user to check if the surface has been completely and evenly covered. Use Aquastop 120 Sealing Tape, Pipe Collars & Corner Pieces to waterproof corners, expansion joints, external and internal angles and water and drainage pipeline crossings.
