Tip component B into component A. Ensure that the hardener drains <br />completely from its container. Mix both components together with a <br />suitable mixer (e.g. drill with paddle) at 300 rpm. Ensure to also stir at the <br />sides and bottom so that the hardener is evenly dispersed. Stir for as long <br />as necessary until the mixture is homogenous (free from streaks); mixing <br />time approx. 3 minutes. During the mixing process the material <br />temperature should be approx. +15°C. Do not use the mixed material <br />directly from the supplied packaging. Decant the material into a clean <br />container and mix through thoroughly once again.</p> <p>1 Load-bearing concrete substrate</p> <p>2 Cleaning the floor substrate</p> <p>3 Priming and suitable tools</p> <p>4 Puncture the lid of the hardener <br />component</p> <p>5 Completely emptying the hardener <br />into the resin</p> <p>6 Mixing, decanting and mixing againy</p> <p>7 Application of the primer on the floor</p> <p>8 Fully broadcast the fresh primer <br />with quartz sand</p> <p>Priming <br />Apply ASODUR®-SG2 to saturation on to the cleaned floor substrate with <br />a rubber squeegee or a lamb’s wool roller, thoroughly work into the <br />surface with a priming brush and back-roll evenly with a short nap paint <br />roller. Blind the fresh primer with quartz sand. <br />Capillary grout in pool edge details <br />ASODUR®-SG2 is used as a capillary breaking grout in pool edge details <br />with a high water level. Mix the resin/hardener of ASODUR®- SG2 at the <br />pre-determined mix ratio and mix in 0.1 – 0.6 mm quartz sand at a mix <br />ratio of 1 : 1 (1 part by volume of mixed resin : 1 part by volume of quartz <br />sand) and fill out into the prepared capillary breaking joint. After approx. <br />15 minutes, fully blind the filled grouted joint with 0.1 – 0.6 mm quartz <br />sand. It is essential to prevent the sand from sinking.</p> <p>Application: <br />The surface to be treated must be dry to matt damp, sound, load-bearing <br />and have a good key. It must be free from separating or adhesion <br />inhibiting substances such as e.g. dust, laitance, grease, rubber residues, <br />paint residues and similar. Dependent on the condition of the substrate, <br />use suitable preparation measures such as e.g. shot blasting, scabbling, <br />planing, brushing, sweeping, vacuuming and grit blasting, high pressure <br />water blasting. Appropriate to each particular substrate, the following <br />criteria are also to be fulfilled: <br />Cement-based areas: <br />• Quality of the concrete: min. C 20/25 <br />• Quality of the screed: min. EN 13813 CT-C25-F4 <br />• Quality of the render: min. P IIIa/P IIIb <br />• Age: min. 28 days <br />• Tensile adhesion strength: 0.8 N/mm2</p> <p>1119</p> <p>SCHOMBURG GmbH & Co.
