INSTRUCTIONS FOR USE
Preparation of substrates
Substrates must comply with BS 5385, parts 1-5, be compact, smooth, absorbent, free from substances that reduce adhesion such as dust, oil, grease and with no loose material. Varnishes and paints must be removed completely. Substrates must be stable, nondeformable and with no cracks. Cement-based substrates must have a residual humidity ≤ 2 % CM. Plasters with a gypsum base must present a residual humidity ≤ 1 % CM, and screeds with an anhydrite base ≤ 0.5 % CM, or ≤ 0.3 % CM if an underfloor heating system is installed.Before waterproofing the substrates must be primed with Primer A Eco, eco-friendly water-based, solvent-free primer, following the instructions for use.
Instruction for use
Nanodefense® Eco is immediately 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 Nanodefense® Eco allows the user to check if the surface has been completely and evenly covered.
Waterproof corners and expansion joints with Aquastop 120 applied using Nanodefense® Eco. For external and internal angles and for
water and drainage pipeline crossings use special pre-formed pieces applied using Nanodefense® Eco.
Tools
Spreader, roller, brush. Wash tools with water before the product hardens.
AREAS OF USE
Use
Waterproofing of smooth, compact and absorbent substrates before laying ceramic coverings with adhesives.
Compatible 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
For internal use. 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
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.
