Stir the <br />A-component (resin) thoroughly before mixing. <br />Component B is added to the thoroughly mixed <br />component A. <br />It should be ensured that the hardener drains completely <br />from its container. A suitable mixer should be used to mix</p> <p>the two components, and this should be completed at <br />approx. 300–500 min-1 (e.g. drilling machine with stirrer) <br />in order to mix in as little air as possible. The contents <br />should also be stirred up from the sides and from the <br />base, so that the hardener will be distributed evenly. <br />Stirring should be continued until the mixture becomes <br />homogeneous (streak-free). Do not apply the mixed <br />material from the delivered packaging! Decant the bulk <br />density to a clean mixing bucket and thoroughly mix again <br />as described above. Total mixing time at least 4 minutes. <br />Method of application / consumption: <br />Primer: <br />In floors, walls and ceilings <br />Apply ASODUR-SG3-thix in two application steps fresh in <br />wet pore sealed!</p> <p>(See Technical Data Sheet ASODUR-SG3-thix)</p> <p>Consumption: </p> <p>approx. 600–1000 g/m²</p> <p>Do not sand the primer coat. Use a low-level wool roller <br />or a whitewash brush to apply the material equally first, <br />and then use a primer brush to brush it into the surface <br />zone meticulously, and then use the wool brush to rework <br />it again afterwards. On the horizontal surfaces, <br />ASODUR-SG3-thix is equally distributed first with a rubber <br />slider, and then the primer brush is used to brush it into the <br />surface zone meticulously, and again a wool roller is used <br />to work it in using a crosswise technique. <br />Protect the surfaces against fouling! Walk on the surface <br />with clean shoe covers only until the complete system <br />construction of the ASOFLEX-AKB / <br />DENSARE-PREMIUM system has completed. <br />Positional requirements for <br />the DENSARE PREMIUM system: <br />In order to enable the electrical monitoring of <br />the waterproofing, after a waiting time of at least 12 hours <br />or max. 5 days, lay the ASO-LB conductive tape in a grid <br />of 10 × 10 m on the surfaces coated with <br />ASODUR-SG3-thix. Roll the ASO-LB conductive tape <br />firmly and guide it out of the surface to be waterproofed <br />at several points for later electrical monitoring.

The joint tape is <br />placed in the fresh layer and then meticulously pressed <br />in without voids or wrinkles. Bonding must be carried <br />out in such a way that water cannot migrate around the <br />back. The joint tape to be used should be inserted in a <br />loop over movement joints. The joint tape edges must be <br />adhered overlapping at least 5–10 cm with <br />ASOFLEX-AKB-Wall, free of wrinkles and covering the <br />whole area. Finally, the bonded joint tapes must be <br />coated over with ASOFLEX-AKB-Wall and seamlessly <br />integrated into the waterproofing. <br />Proceed in the same way when inserting <br />ASO joint tape pre-formed pieces. Structural movement <br />joints are waterproofed in the same way, whereby <br />ASO-Joint-Tape-2000-S is worked into the joint crosssection in a loop-like manner. <br />Use the ASO-Joint-Tape-2000-Cross piece or <br />ASO-Joint-Tape-2000-T shaped pieces in the area of the <br />intersecting structural movement joints, expansion joints <br />and connecting joints, which also allow a loop-like design <br />in the intersection area. <br />Surface waterproofing, after a sufficient waiting time of <br />at least 16 hours so that previous waterproofing work will <br />not be damaged, overcoat the ASO-Joint-Tape-2000-S <br />joint tape technology with ASOFLEX-AKB-Wall/-Floor for <br />at least 5 cm during the course of surface waterproofing.</p> <p>Expansion and connecting joints, Bond <br />ASO-Joint-Tape-2000-S / ASO-Joint-Tape-2000-S <br />internal/external corners in the corner areas, in the</p> <p>5/9</p> <p>11/22</p> <p>ASOFLEX-AKB-Floor <br />ASOFLEX-AKB-Wall <br />ASOFLEX-AKB system structure: <br />Horizontal surfaces</p> <p>Vertical surfaces</p> <p>a.

The epoxy resin adhesives <br />ASODUR-EKF and CRISTALLFUGE-EPOX already after 16 hours. The waterproofing layer must be totally hardened at the time of the laying work. )1 Possible <br />additional consumption in case of uneven substrates and artisanal variations must be considered. Therefore a thickness allowance of at least 25 % must be <br />taken into account in accordance with the DIN 18534 standard. The times specified are applicable for ambient conditions of +23 °C and 50 % relative <br />humidity! The substrate temperature must be at least 3 K above the dew point temperature during coating work! The Additional Technical Information No. 19 <br />"Processing of ASODUR Products", containing a dew point table, must be complied with.</p> <p>7/9</p> <p>11/22</p> <p>ASOFLEX-AKB-Floor <br />ASOFLEX-AKB-Wall <br />Important advice: <br />• SCHOMBURG products are normally delivered in <br />working packs, i.e. in matched and predetermined mix <br />ratios. For deliveries in large packs, partial quantities <br />must be weighed out using a scale. Always stir up <br />the filled components thoroughly and only then mix <br />them with the second component. This takes place using <br />a suitable stirrer, e.g. a round-plate mixing machine <br />or equivalent. To avoid mixing errors, the material is <br />transferred to a clean container and mixed again. <br />The mixing speed should be approx. 300–500 min1. <br />Ensure that air is not mixed in. The temperature of <br />the components should be minimum +15 °C. Then <br />apply the completely mixed material immediately to <br />the prepared substrate and distribute meticulously in <br />accordance with the instructions in the technical data <br />sheets. <br />• T he use of short pile nylon fur rollers (6 mm) <br />with textured polyamide cover or equivalent is <br />recommended. <br />•H <br /> igher temperatures shorten, lower temperatures <br />extend the application and hardening times. <br />•S <br /> everely absorbent substrates that tend towards pores, <br />bubbles, pinholes must be treated beforehand. In <br />addition to this, 6–8 % ASO-FF (fibre filler material) <br />is mixed into ASODUR-SG3-thix. Using the levelling <br />compound that is created, a scratch coat is completed <br />first. Next, a 4 mm toothed trowel is used for fresh-infresh application, and then the layer is smoothed off. <br />After the material has hardened, ASODUR-SG3-thix <br />is used to prime after 12 hours or max. 5 days, as <br />described in the application procedure under "Priming" <br />or in the system structure under a. <br />•C <br /> olours: Slight colour differences, caused by different <br />production batches and raw material fluctuations may <br />occur and are not significant for the waterproofing <br />function. <br />• T he bonding between the individual layers can <br />be strongly disrupted between the individual <br />application steps due to the effects of dampness and <br />contamination! Coating work requires a substrate</p> <p>temperature of at least 3 K above the dew point <br />temperature. <br />• If longer waiting times arise between the individual <br />application steps or surfaces that have already been <br />treated with liquid resin are coated again after an <br />extended period of time, the old surface must be well <br />cleaned and thoroughly ground and then primed with <br />INDU-Primer-N. Then apply a complete pore-free new <br />coating. <br />• Surface protection systems must be protected against <br />moisture (e.g. rainwater, condensation water) after <br />application until they have reacted. Moisture results in <br />surface stickiness and may result in pores/bubbles and <br />interference with hardening. Discoloured and/or sticky <br />surfaces must be removed and reworked, e.g. through <br />grinding or shot blasting. <br />• The indicated consumption quantities are calculated <br />values without additions for surface roughness and <br />absorbency, level compensation, and residual <br />material in the container. We recommend a calculated <br />safety addition on top of the calculated consumption <br />quantities. <br />• The relevant regulations are to be taken into account! <br />For example: <br />DIN 18157 <br />DIN 18352 <br />DIN 18531 <br />DIN 18534 <br />DIN 18352 <br />DIN 18560 <br />DIN 18202 <br />EN 13813 <br />DIN EN 1991-1-1 <br />The BEB data sheets, issued by the Bundesverband <br />Estrich und Belag e.V.
