Half-fill the mixing drum with aggregate (0/8, approx. 15 scoops of 7 kg each), 50 kg ASO®-SEB and approx. 7.5 l water. <br />2. Add the remaining aggregate and then the remaining water. <br />3. The total mixing time is ca 2 - 3 minutes. <br />4. Protect the fresh screed to prevent it drying out too rapidly, e.g. due to heat or draughts. <br />5. Tiles are ready for laying after one day if the following prerequisites are met: * Mix ratio of 1:4 parts by weight * Dry aggregate (DIN 4226; <br />grading curve A8 - B8 close to B8; constant grading) * Water addition of 15 litres on 50 kg ASO®-SEB * Ambient and substrate temperature: <br />+23 °C * Rel. humidity of 50% * Layer thickness of 5 cm <br />6. When it comes to other surface coverings, use the CM method to test the moisture content. <br />7. In the case of screeds that are required to satisfy a certain screed quality in accordance with DINEN13813, a performance test is necessary. <br />This must be performed before starting the work.</p> <p>SCHOMBURG GmbH & Co.

These are aggregates rich with fine <br />parts, which require a greater quantity of water and binder in comparison to the optimum grading curve between A8-B8 close to B8. However, <br />in accordance with investigations by the institute for building material testing and flooring research (“IBF”), use of such aggregates stands at <br />almost 70% nationwide. Such aggregates are generally good to apply and smooth, but they require a greater quantity of water and binding <br />agent in order to achieve similar strengths as with optimum grains. Our investigations with the adjacent typical representatives of aggregates rich <br />with fine parts have shown that ASO-SEB in conjunction with grading curves around C8 and above can be used to produce good screeds if the <br />formula is correspondingly adjusted (binder and added water).</p> <p>Cleaning tools <br />Clean tools thoroughly with water after use.</p> <p>Storage conditions <br />Storage <br />Store in a cool and dry place. Min. 6 months in the original canister. Promptly use opened container.</p> <p>Notes <br />Do not add any additives and substances! <br />Observe the technical data sheets of the products mentioned before starting work. <br />For use in areas with inadequate aggregate quality or where storage of the mortar components is not possible or desirable, the ASO®-SEM <br />/ ASO®-EZ4-PLUS pre-blended dry mortars are available! <br />A moisture measurement must be carried out using the CM method to assess whether it is ready to receive. <br />Low temperatures, high humidity and heavy layer thicknesses delay hardening, drying and extend the time until ready to receive tiles. (Also <br />see the BEB data sheet “Building climate preconditions for drying screeds”). Tests showed that the crystalline binding of the water is slower at <br />low temperatures (+5 to +10°C), meaning that the screed was only ready to receive tiles after a longer period of time! <br />Water that is pressed out of the surface of the screed indicates excessive water or aggregate addition (more than 3.3: 1 volume – parts, <br />equates to approx. 5: 1 parts by weight), an incorrect grading curve or inadequate mixing. A consequence of this will be a crumbling <br />surface! <br />The quality of the aggregate used is partly decisive for the properties of the screed produced with it. Aggregate after DIN 4226 should be <br />used with a constant grading curve between A and B close to B after DIN 1045. If aggregates with other grain distributions are used, a <br />greater quantity of binder may be required. Aggregates with a grading curve between B and C after DIN 1045 require a higher proportion <br />of ASO®-SEB. The grain size distributions that should be used with different layer thicknesses are available in the “Layer thickness in <br />accordance with grading curve” table. <br />ASO®-SEB can crystalline bind approx. 25% of its weight to water. Water quantities that exceed this volume must evaporate and therefore <br />delay the readiness to receive tiles and boards! <br />If the surface of the screed cannot be closed sufficiently when rubbed, this indicates that the proportion of fines in the aggregate is too low. A <br />higher quantity of ASO®-SEB is required to replace the missing proportion of fines! <br />If moisture rises from the substrate, effective waterproofing is essential prior to laying the screed! <br />The installation location must be ventilated. However, draughts and direct solar radiation should be avoided during application and the <br />hardening process. The indoor temperature and floor temperature must be at least +5°C during application, and during the following week! <br />Air dehumidifiers may not be used during the first 3 days! <br />Do not add any other cement or binder! <br />Border, field, building separation and movement joints should be carried over to or installed at the designated location; suitable means (e.g. <br />edge strips) should be used to detach them!</p> <p>Relevant regulations <br />Planning, inspection of substrates and building site circumstances, laying, grouting and subsequent <br />care of the work must be done in accordance with the relevant DIN standards and recognised rules of <br />technology (e.g. the ZDB Data sheets of the Zentralverband Deutsches Baugewerbe e.V.(German <br />construction Association) in the latest version. <br />Observe applicable safety data sheet!</p> <p>SCHOMBURG GmbH & Co.
