Product preparation: Component A (resin) and component B (hardener) are delivered in the predetermined mix ratio. The material temperature should be at least +15 to +25°C during the mixing procedure. Stir the A-component (resin) thoroughly before mixing. Component B is added to the thoroughly mixed component A. It should be ensured that the hardener drains completely from its container. A suitable mixer should be used to mix
the two components, and this should be completed at approx. 300–500 min-1 (e.g. drilling machine with stirrer) in order to mix in as little air as possible. The contents should also be stirred up from the sides and from the base, so that the hardener will be distributed evenly. Stirring should be continued until the mixture becomes homogeneous (streak-free). Do not apply the mixed material from the delivered packaging! Decant the bulk density to a clean mixing bucket and thoroughly mix again as described above. Total mixing time at least 4 minutes.

ASOFLEX-AKB-Floor ASOFLEX-AKB-Wall Important advice: • SCHOMBURG products are normally delivered in working packs, i.e. in matched and predetermined mix ratios. For deliveries in large packs, partial quantities must be weighed out using a scale. Always stir up the filled components thoroughly and only then mix them with the second component. This takes place using a suitable stirrer, e.g. a round-plate mixing machine or equivalent. To avoid mixing errors, the material is transferred to a clean container and mixed again. The mixing speed should be approx. 300–500 min1. Ensure that air is not mixed in. The temperature of the components should be minimum +15 °C. Then apply the completely mixed material immediately to the prepared substrate and distribute meticulously in accordance with the instructions in the technical data sheets. • T he use of short pile nylon fur rollers (6 mm) with textured polyamide cover or equivalent is recommended. •H igher temperatures shorten, lower temperatures extend the application and hardening times. •S everely absorbent substrates that tend towards pores, bubbles, pinholes must be treated beforehand. In addition to this, 6–8 % ASO-FF (fibre filler material) is mixed into ASODUR-SG3-thix. Using the levelling compound that is created, a scratch coat is completed first. Next, a 4 mm toothed trowel is used for fresh-infresh application, and then the layer is smoothed off. After the material has hardened, ASODUR-SG3-thix is used to prime after 12 hours or max. 5 days, as described in the application procedure under "Priming" or in the system structure under a. •C olours: Slight colour differences, caused by different production batches and raw material fluctuations may occur and are not significant for the waterproofing function. • T he bonding between the individual layers can be strongly disrupted between the individual application steps due to the effects of dampness and contamination! Coating work requires a substrate
temperature of at least 3 K above the dew point temperature. • If longer waiting times arise between the individual application steps or surfaces that have already been treated with liquid resin are coated again after an extended period of time, the old surface must be well cleaned and thoroughly ground and then primed with INDU-Primer-N. Then apply a complete pore-free new coating. • Surface protection systems must be protected against moisture (e.g. rainwater, condensation water) after application until they have reacted. Moisture results in surface stickiness and may result in pores/bubbles and interference with hardening. Discoloured and/or sticky surfaces must be removed and reworked, e.g. through grinding or shot blasting. • The indicated consumption quantities are calculated values without additions for surface roughness and absorbency, level compensation, and residual material in the container. We recommend a calculated safety addition on top of the calculated consumption quantities. • The relevant regulations are to be taken into account!
