C20/25 <br />Screed quality: <br />min. EN 13813 CT-C25-F6 <br />Tensile adhesion strength: > 1.5 N/mm2 <br />Product preparation: <br />Component A and component B are delivered at <br />a predetermined mixing ratio. Tip component B <br />into component A. Ensure that the hardener drains <br />completely from its container. Mix both components with <br />a suitable mixer at 300 rpm. It is important to ensure <br />that the hardener is evenly dispersed. Stir until the mix is <br />homogenous (free from streaks); mixing time approx. <br />3 minutes. The minimum temperature during mixing should <br />be around +15° C.</p> <p>*) “Guidelines for the protection and repair of concrete sections”, part 2, <br />section 2.3.5 “Concrete moisture”, 07.2002.</p> <p>Prepare substrates with reference to <br />DIN EN 14879-1:2005, 4.2 following. <br />Dependent on the condition of the substrate to be treated, <br />use suitable mechanical preparation methods, e.g. high <br />pressure water blasting, scabbling, shot blasting, planing <br />etc, with which a textured, open surface is achieved. <br />(Repair voids and cracks beforehand with a suitable <br />product from the SCHOMBURG range).</p> <p>Do not use mixed material directly from the packaging. <br />Decant the mixed material into a clean container and mix <br />through thoroughly once again. <br />Application method/consumption: <br />Using a rubber squeegee, apply ASODUR-SG2 to <br />saturation onto the cleaned, matt damp substrate and <br />thoroughly work into the surface with a priming brush <br />and back roll with a short nap paint roller. Blind the <br />fresh primer with quartz sand (grain size: 0.5 – 1.0 mm <br />diameter). Once hardened, carefully remove all nonbound quartz sand before subsequent coatings are <br />applied to the primer.</p> <p>Oil contaminated concrete: <br />•• Following the preparation of the substrate, treat the <br />affected area with the cleaning agent ASO-R008 <br />(diluted in accordance with the technical data sheet for <br />ASO-R008). <br />•• Clean the treated area with warm water (approx. <br />+50°C to +70°C). <br />•• Remove excess water with a suitable vacuum. <br />•• Apply ASODUR-SG2 immediately to the surface whilst <br />it is still damp, working in with a brush and finishing <br />evenly with a paint roller. <br />Please note: No completely closed water film must be <br />present on the surface of the concrete. The substrate may <br />not dry out – with drying there is a risk that the oil will rise</p> <p>Material consumption: <br />Dependent on the substrate, the consumption is between <br />600 to 1000 g/m2. <br />Consumption of broadcast sand approx. 1500 g/m2.</p> <p>2/4</p> <p>28/18</p> <p>After waiting for approx. 12–24 hours any ASODUR <br />coating system can be applied, beginning with the primer <br />belonging to the system or alternatively other floor finishes <br />can be applied.</p> <p>fillers to be mixed, e.g. sands. The addition of the fillers <br />is only to occur once both liquid components have <br />been blended. Afterwards place the completely mixed <br />material immediately on to the prepared substrate and <br />quickly and carefully spread out in accordance with the <br />instructions in the technical data sheet. For applications <br />by roller, it is recommended to use a short nap nylon <br />paint roller (6 mm) with a textured polyamide cover or <br />similar. Always thoroughly stir one component products <br />before use. <br />•• Higher temperatures shorten the pot life. Lower <br />temperatures increase the pot life and setting time. <br />Material consumption is also increased at lower <br />temperatures. <br />•• Colours: Small variations in colour, resulting from <br />varying production batches and raw material <br />fluctuations, are unavoidable. When applying coatings, <br />take this into consideration. Carry out neighbouring <br />sections with the same production batch (same batch <br />number on the packaging). <br />•• The bond between individual coats can be heavily <br />impeded by the penetration of moisture and <br />contamination between the individual coats. Coating <br />work requires a substrate temperature of at least 3°C <br />above the dew point temperature. <br />•• If there is a long down time between individual coats <br />or if already treated areas are to be renewed with <br />liquid resins after a long period of time, then the old <br />surface is to be well cleaned and thoroughly abraded. <br />Afterwards carry out a completely new pinhole free <br />coating. <br />•• Surface protection systems must be protected from <br />moisture (e.g. rain, melt water) after their application <br />for approx. 4–6 hours. Moisture produces a white <br />discolouration and/or stickiness on the surface and <br />can lead to interference in the curing process. Take off <br />discoloured and/or sticky surfaces by e.g. planing or <br />abrasive blast techniques and renew. <br />•• Consumption quantities given are values determined by <br />calculation without additions for surface roughness or</p> <p>Capillary breaking fluid grout: <br />When using ASODUR-SG2 as a capillary grout, fill the <br />ASODUR-SG2 with 0.1–0.6 mm quartz sand at a mixing <br />ratio of 1:1 parts by weight. <br />Mix density: approx. 2.15 g/cm³ <br />Consumption: approx. 2,150 g/Liter <br />Broadcast the surface of the resin, before it hardens, with <br />0.5–1.0 mm quartz sand. <br />Important advice: <br />•• When using organic acids (e.g. propanoic acid), or if <br />they are present in drive-in silo plants, ASODUR-SG2 <br />may not be used as the only waterproofing and <br />surface protection measure. ASODUR-SG2 is to be <br />coated with a top coat material appropriate to the <br />service conditions. <br />•• When using ASODUR-SG2 as a vapour barrier <br />beneath conventional floor coverings e.g. PVC, <br />linoleum, carpet and parquet, do not use solvent based <br />adhesives. This will lead to bulging in the floor finish <br />installed. <br />•• Use ASODUR-SG2-thix for vertical surfaces. <br />•• As a rule, SCHOMBURG products are supplied in <br />working packs i.e. at a mix ratio matched together. <br />When supplied in large containers, part quantities must <br />be weighed out using a balance. Always thoroughly <br />stir the filled components and only then mix with the <br />second component. This is to be executed with a <br />suitable stirrer e.g. Polyplan/Ronden mixing paddle <br />or similar. In order to exclude mixing errors, decant <br />into a clean container and mix anew. The mixing <br />speed should be approx. 300 rpm. Ensure that no air <br />is mixed in. The temperature of the components should <br />be minimum +15°C. This is also valid for any potential</p> <p>3/4</p> <p>28/18</p> <p>absorption, levelling or residues in the containers. We <br />recommend adding a calculated safety factor of 10% <br />to the computed consumption quantities. <br />•• Applications, which are not clearly mentioned in this <br />technical data sheet may only be implemented after <br />consultation with and written confirmation from the <br />technical service department of SCHOMBURG. <br />•• Cured product residues can be disposed of using <br />waste disposal code AVV 150106. <br />Please observe a valid EU safety data sheet. <br />GISCODE: RE 2</p> <p>This technical data sheet does not consider local building codes or legal requirements.
