Use <br />opened containers promptly.</p> <p>Areas of application: <br />ASODUR-SG3 is used <br />•• as a moisture barrier primer on cement-based surfaces <br />•• as a primer on ceramic finishes, multi-layer wooden <br />boards and similar, which are to be coated with <br />ASODUR systems <br />•• for producing levelling compounds and scratch coats <br />•• for preparing substrates beneath conventional floor <br />finishes such as PVC, Linoleum, carpet and others</p> <p>1/4</p> <p>48/17</p> <p>Substrate preparation: <br />The areas to be treated must be: <br />•• Dry or damp (in accordance with DAfStB RiLi SIB*), <br />solid, load-bearing and have a good key. <br />•• Free from separating and adhesion reducing <br />substances such as e.g. dust, laitance, grease, rubber <br />marks, paint residues and similar. <br />Furthermore, ASODUR-SG2-thix can also be used on the <br />following substrates: <br />•• Concrete and cement-based screed areas subjected to <br />reverse moisture penetration <br />•• Concrete and cement-based screed areas with <br />increased residual moisture*</p> <p>special primer and the substrate. <br />Appropriate to each particular substrate, the following <br />criteria are also to be fulfilled: <br />Concrete quality: <br />min. C 20/25 <br />Screed quality: <br />min. EN 13813 CT-C25-F6 <br />Tensile adhesion strength: >1.5 N/mm2 <br />Product preparation: <br />Components A (resin) and B (hardener) are delivered <br />at a predetermined mixing ratio. Tip component B into <br />component A. Ensure that the hardener drains completely <br />from its container. Mix both components together using <br />a suitable rotary stirrer at approx. 300 rpm (e.g. mixing <br />paddle and drill). It is important that stirring agitates the <br />sides and bottom so as to equally disperse the hardener. <br />Stirring is to be continued until the mix is homogenous <br />(free from streaks): mix time 3 minutes. During the mixing <br />process the temperature should be approx. +15 °C. <br />Do not use mixed material directly from the packaging! <br />Decant the mixture into a clean mixing bucket and <br />thoroughly stir through once again. <br />Note: <br />When applying the product please ensure that the <br />material is evenly “flooded” over the prepared substrate. <br />Uneven areas lead to capillary pores in the hardened <br />priming coat, which benefits the formation of bubbles, <br />especially osmosis bubbles. To ensure a pore free priming <br />coat, apply the primer in two coats “wet in wet”. The <br />pore-free finish can be enhanced by the application of <br />a second coat of a watertight smoothing mortar. This <br />smoothing mortar is to be produced from the priming <br />resin with the addition of quartz sand – see production: <br />levelling/key coat. <br />When mixing aggregate (e.g. quartz sand) it must be <br />ensured that the aggregate is dry and is also at +15 °C. <br />Production of levelling/key coats: <br />ASODUR-SG3: <br />1.0 part by weight <br />Quartz sand: approx. 1.0 part by weight <br />(particle size 0.1 - 0.6 mm) <br />Fibre filler ASO-FF: <br />approx. 2–3 % by weight</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). <br />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-thix immediately to the surface <br />whilst it is still damp, working in with a brush and <br />finishing 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 <br />again and thus no bond will be achieved between the</p> <p>2/4</p> <p>48/17</p> <p>The quartz sand is to be added to the previously mixed <br />and decanted resin and hardener components. Ensure <br />that the liquid and solid components are evenly dispersed.</p> <p>is mixed in. The temperature of the components should <br />be minimum +15°C. This is also valid for any potential <br />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.</p> <p>Method of application / consumption: <br />Priming: <br />ASODUR-SG3 is flood applied in one application to fill <br />the pores. <br />Consumption: approx. 400–700 g/m² <br />Advice: <br />•• Overcoat the clean, primed area within 12 hrs to max. <br />5 days. <br />•• Primer not ‘broadcast’ with quartz sand may only be <br />walked on with clean “overshoes”. <br />“Broadcasting” a second coat of primer with quartz sand <br />is possible (grain size: e.g. 0.1–0.6 mm). <br />Consumption: approx. 0.8–1.0 kg/m² <br />Once hardened, thoroughly remove all non-bound quartz <br />before installing a roller applied or self-levelling coating / <br />scratch coat or screed. <br />Levelling layer/scratch coat: <br />Firstly prime the substrate with ASODUR-SG3. The mixed <br />smoothing mortar is applied in one operation using <br />scratch coating techniques. <br />Consumption of finished smoothing mortar: <br />approx. 1,600 g/m² per mm thickness <br />Important advice: <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</p> <p>3/4</p> <p>48/17</p> <p>•• Consumption quantities given are values determined by <br />calculation without additions for surface roughness or <br />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 1</p> <p>Information about the emission level of volatile compounds in indoor <br />air, which pose a health risk by inhalation, on a scale from class A+ <br />(very low emissions) to C (high emissions).</p> <p>This technical data sheet is a translation from German and does not consider local building codes or legal requirements.
