Even <br />2. Free of adhesion inhibiting substances <br />3. Sealed in the surface <br />4. Pore open <br />5. Load-bearing <br />6. Extensively fully grouted</p> <p>Preparing the surface <br />1. In the case of substrates damaged by de-icing salt, the substrate must be removed down to the neutral area, e.g. by means of milling, etc. <br />2. Pre-moisten the dry substrate so that it is matt damp at the time of application. <br />3. Extremely absorbent and slightly sandy substrates must be primed with AQUAFIN-Primer. <br />4. Moisture penetration from the rear and intermittent moisture loading from the negative side must be avoided.</p> <p>Application <br />Mixing <br />1. Put the liquid component into a clean mixing bucket and mix with the powder component to produce a homogeneous, lump-free mass. <br />2. The mixing time is ca. 3 minutes. <br />3. After a settling period of ca. 2 minutes, thoroughly homogenise the compound again.</p> <p>Application <br />1. Apply AQUAFIN®-OS as scratch coat and contact layer before first application. <br />2. Immediately afterwards, the first layer of sealant is applied wet-on-wet. <br />3. The second application step (and following) can take place when the first application step can no longer be damaged by reworking. (see <br />“Technical Data > Application”) <br />4. The waiting time between layers depends on temperature, humidity and other ambient conditions.</p> <p>Cleaning tools <br />Clean tools thoroughly with water after use.</p> <p>Notes <br />Protect surfaces that are not to be treated from the effects of AQUAFIN®-OS! <br />AQUAFIN®-OS as a surface coating must not be exposed to point or linear loads. <br />AQUAFIN®-OS may be plastered and coated with vapour permeable, solvent-free dispersion facade paints or dispersion silicate paints (not <br />pure silicate paints). Silicon resin paints and acrylate-based paints may also be used. <br />On PVC, gunmetal, and stainless steel flanges, ASO®-Dichtmanschetten or alternatively ADF®-Pipe-Gasket must be installed without voids or <br />wrinkles and integrated seamlessly into the waterproofing. <br />In case of strong sunlight, work against the movement of the sun in shaded areas. <br />Direct contact with metals such as copper, zinc, and aluminium must be avoided by means of a pore sealed primer. A pore-sealed primer is <br />produced via 2 application steps using ASODUR®-GBM (see technical data sheet). <br />In rooms with high humidity and/or insufficient ventilation (e.g. water containers), dropping below the dew point (condensation formation) <br />may occur on the surface. This must be avoided by taking suitable measures such as by using condensation dryers. Direct heating or <br />uncontrolled blowing warm air is not permitted. <br />The waterproofing must not be affected by water during binding. The effect of water from behind can lead to spalling in case of frost.</p> <p>Observe applicable safety data sheet!</p> <p>The rights of the buyer with regard to the quality of our materials are based on our terms and conditions of sale and delivery.
