Kerakoll Aquastop Nanoflex extended information
Coverage: 1.15 kg/m2 per mm of thickness
Areas of Application
Use
Terraces, balconies, horizontal surfaces and swimming pools on mineral screeds, monolithic cement-based screeds, existing floors covered with ceramic and marble tiles, dimensionally stable natural stone well-anchored to the substrate and clean, cement-based plasters/ renders and cementitious mortars, aged concrete.
Do not use on gypsum or anhydrite-based substrates without the use of eco-friendly Kerakoll Primer A Eco, water-based surface isolation, on metal or wood substrates, on bituminous sheeting, to waterproof exposed surfaces subject to foot traffic, on low-density screeds, on insulation layers on inverted roofs made with isolation panels or lightened materials, in swimming pools and tanks used to hold exposed water, when adhesion of the coverings requires the use of Kerakoll H40 Extreme or reactive adhesives.
Instructions for Use
Preparation of substrate
The substrate must be perfectly cured and dry, solid (i.e. free of weak or easily removable parts) and free from oil, grease, paint and parting compound. When working on weakened parts, when parts of the substrate are missing and also in the case of honeycombs, the substrate must be restored with suitable products.
Correct uneven areas with suitable finishing products. On ceramic substrates all traces of surface treatments such as wax and oil must be removed. The most suitable cleaning methods are sandblasting, mechanical scarification or washing with detergents and jet washing. Before application damp the surface of absorbent substrates, without letting any stagnant water. Waterproof the perimeter, expansion and desolidarisation joints in the substrates using Aquastop 120 anchored using Aquastop Nanoflex; create special pieces for external angles, internal angles and connections to drains and installations by cutting the Aquastop 120 tape.
Waterproof the structural joints with appropriate waterproofing systems.
Preparation
Prepare Aquastop Nanoflex in a clean container by pouring in approximately 3⁄4 of the water required. Gradually add Kerakoll Aquastop Nanoflex to the container, mixing the paste from the bottom upwards with a low-rev (≈ 400/min) agitator. Add more water until the desired consistency is obtained. The mixture must be of smooth consistency and without any lumps.
The amount of water to be added, indicated on the packaging, is an approximate guide. It is possible to obtain mixtures with a more or less fluid consistency, depending on the type of application.
Application
Aquastop Nanoflex should be applied with a smooth spreader on a previously prepared substrate. Apply the first coat about 1 – 2 mm thick, pressing down to ensure maximum adhesion to the substrate. Once hardened and after removing any surface condensation, apply the second coat of Kerakoll Aquastop Nanoflex. Apply a continuous, even layer about 2 – 3 mm thick covering the substrate completely. When waterproofing with Aquastop AR1 mesh, submerge the reinforcing mesh fully in the first layer of freshly applied waterproofing product, pressing down with the spreader. The subsequent laying of the covering with Kerakoll H40 Gel range inorganic adhesive should be placed at least 24 hours after the last layer has been applied. when working in low temperatures and with high humidity, the waiting time before laying will be longer. If rain falls on the product before it is fully hardened, check it is ready before applying the next coat/covering.
Cleaning
Residual traces of Aquastop Nanoflex can be removed from tools with plain water before the product hardens.
Special Notes
Pools, tanks, basements and foundations in cured reinforced concrete: break the spacer holes mechanically and clean them suitably, then apply Aquastop Nanosil neutral organic silane sealant and level the surface with a suitable finishing product. Waterproof the corners by anchoring Aquastop 120 tape with adhesive from the Kerakoll H40 Gel range, creating special pieces for external angles, internal angles and connections to drains and installations by cutting the tape itself. Where there is insufficient space to use Aquastop 120 tape, apply Aquastop Nanosil sealant.
Surfaces subject to foot traffic: use Aquastop Traffic to protect untiled surfaces that have been waterproofed using Aquastop Nanoflex.
