Following successful substrate preparation, pre-treat the surfaces concerned with the cleaning material ASO®-R008 (dilution in accordance with <br />the technical data sheet of ASO®-R008). <br />2. Clean the treated surfaces with warm water (approx. +50 °C to +70 °C). <br />3. Remove excess water with suitable suction equipment. <br />4. Apply ASODUR®-SG2 by brush and roller. <br />5. Please note: No sealed water film may be present on the surface of the concrete! The substrate may not be dried off; drying off results in the <br />danger that rising oil could negate bonding of the special primer to the substrate. <br />6. The still fresh primer is sprinkled with quartz sand (Ø 0.5-1.0 mm) covering the whole area.</p> <p>Application <br />Mixing <br />1. The (ideal) material temperature during the mixing procedure is +15 °C. <br />2. Mix the resin homogeneously in the original container. <br />3. Add the hardener to the resin. <br />4. The hardener must run completely out of the container. <br />5. Mix thoroughly with the mixer until a homogeneous consistency. <br />6. The hardener must be distributed evenly. <br />7. The mixing time is ca. 3 minutes. <br />8. Decant the mass into a clean bucket. <br />9. Stir carefully again. <br />10. When adding quartz sands, make sure that they are kiln-dried and, like other aggregates, also have a temperature of approx. +15 °C.</p> <p>Application <br />1. ASODUR®-SG2 is applied generously to the prepared substrate with a suitable tool. <br />2. Meticulously brush into the surface area with a primer brush. <br />3. Roll on evenly with a short-pile fur roller. <br />4. The fresh primer is sprinkled with quartz sand (Ø 0.5-1.0 mm) to cover the entire surface. <br />5. After the sanded layer has cured, the unbound quartz sand is meticulously removed before the next application step. <br />6. After a waiting time of approx. 12 to 24 hours, work can continue with an ASODUR® coating system or the floor covering structure.</p> <p>Capillary-breaking joint filler <br />1. Add the quartz sand (Ø 0.1 - 0.6 mm) in the predetermined quantity (1:1) to the forced paddle mixer. <br />2. Then add the mixed resin mixture. <br />3. Mix the liquid and solid components evenly. <br />4. Prime the substrate with ASODUR-SG2. <br />5. Pour in the mortar mixture while still wet and spread and compact evenly. Consumption of mixture approx. 2.2 kg/l.</p> <p>SCHOMBURG GmbH & Co.

At min. 10 - 25 °C for 24 months in the original canister. Promptly use opened container.</p> <p>Disposal <br />Hardened product leftovers can be disposed of in accordance with disposal code AVV 15 01 06.</p> <p>Notes <br />The indicated consumption quantities are calculated values without additions for textured surface roughness and absorbency, level <br />compensation and residual material in the container. We always recommend a calculated safety addition of 10% on top of the calculated <br />consumption quantities. <br />Higher temperatures shorten the pot life. Lower temperatures increase the application and hardening times. The rate at which material is <br />consumed also increases at lower temperatures. <br />The bonding between the individual layers can be strongly disrupted between the individual application steps due to the effects of dampness <br />and contamination. Coating work requires a substrate temperature of at least 3 °C above the dew point temperature. <br />If longer waiting times arise between the individual application steps or surfaces that have already been treated with liquid resin are coated <br />again after an extended period of time, the old surface must be well cleaned and thoroughly roughened. Then apply a complete pore-free <br />new coating. <br />Ensure there is good ventilation during the drying and hardening phases. <br />After they have been applied, surface protection systems must be protected against dampness (e.g. rainwater, condensation water) for <br />approx. 4–6 hours. Moisture causes a white colour and/or stickiness on the surface and can cause problems during hardening. Discoloured <br />and/or sticky surfaces must be removed and reworked, e.g. through grinding or shot blasting. <br />If ASODUR®-SG2 is used as a vapour barrier under conventional floor coverings, e.g. PVC, linoleum, carpet and parquet, then no adhesive <br />containing solvents may be used. This leads to persistent buckling in the applied floor covering. <br />If organic acids (e.g. propionic acid) are used or present in mobile silo systems, ASODUR®-SG2 must not be used as the sole waterproofing <br />and surface protection measure. ASODUR®-SG2 must be coated with a top coat adapted to the usage requirements. <br />Observe the technical data sheets of the products mentioned before starting work. <br />Applications that have not been clearly mentioned in this technical data sheet may only be carried out after the technical service department <br />of SCHOMBURG GmbH has been consulted, and after the said department has approved of such a course of action in writing. <br />For detailed information on application, read and observe supplementary technical information no. 19 "Applying ASODUR® products".</p> <p>Relevant regulations <br />The recognised standards of construction engineering, the relevant guidelines and current regulations <br />must be observed. <br />Observe applicable safety data sheet! <br />GISCODE: RE 90</p> <p>SCHOMBURG GmbH & Co.
