Pot life*: after approx. 16 hours Foot traffic*: after approx. 16 hours Overcoat*: * Fully cured : after 7 days Tensile adhesion strength: > 1.5 N/mm2 Cleaning: Immediately after use, clean tools meticulously with ASO-R001. Packaging: 30 Kg containers Component A and component B are in the predetermined mix ratio. Storage: Frost-free, cool and dry, ≥ +10 °C to +25 °C, 18 months in the original unopened container, use opened container promptly. Note: Frequent temperature changes may cause crystallisation in ASODUR-B3311. It is then necessary to heat the product in a water bath (+50 °C to +60 °C) for approx. 2 hours to allow unrestricted use. * The values apply to +23 °C and 50% relative humidity.
Substrate preparation: The surfaces to be treated must be • dry, firm, load-bearing and grippy • free of separating and adhesion inhibiting substances, e.g. dust, slurry, grease, rubber abrasion, coating residues, etc. • protected from the effects of moisture from the rear. Substrate preparations must be carried out in compliance with DIN EN 14879-1:2005, 4.2 et.seq.

Depending on the condition of the substrate to be treated, suitable mechanical methods, e.g. high-pressure water jetting, milling, shot blasting, grinding, etc., are to be used to achieve a structured, open surface. (Larger voids and cracks must be repaired in advance using suitable products from the SCHOMBURG range.) In accordance with the respective substrate, the following criteria must also be met: Cement-based surfaces: • Quality of concrete: min. C 20/25 • Quality of screeds: min. CT-C25-F4 Tensile adhesion strength: ≥1.5 N/mm2 Age: min. 28 days •Q uality of the plaster: min. P IIIa/P IIIb Tensile adhesion strength: approx. 0.8 N/mm2 Residual humidity: < 4% (CM method)
Product preparation: Component A (resin) and component B (hardener) are delivered in the predetermined mix ratio. Component B is added to component A. It should be ensured that the hardener runs completely out of its container. A suitable mixer should be used to mix the two components, and this should be done at approx. 300 rpm (e.g. drilling machine with stirrer). 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); mixing time: approx. 3 minutes. The material temperature should be at the approximate level of +15 °C during the mixing procedure. Do not apply the mixed material from the delivered packaging! Decant the mass into a clean container, and stir meticulously once again. Before application on vertical and inclined surfaces it is recommended to add ASO-FF. The added amounts are between 1 and 2 weight %.
Production of offsetting/scratch coat material: ASODUR-GBM: 1.0 parts by weight Quartz sand: 1.0 parts by weight (grain size: 0.1–0.6 mm Ø) ASO-FF: approx. 1.5 to 2.0 weight % The quartz sand is mixed into the previously homogeneously mixed and repotted resin and hardener component of the binder ASODUR-GBM. Care must be taken that the liquid and solid components are mixed evenly. Method of application/consumption: 1. Prior substrate preparation 2. Production of the fillets in the wall/floor area (radius: approx. 5 cm): 2.1 Priming in the fillet area: ASODUR-GBM is applied by brush or roller in a single application step. Consumption: approx. 40 g/running metre (with a fillet radius of approx. 4–5 cm). 2.2 Creation of the fillets: The coved fillet mortar ASODUR-EMB is applied into the still fresh primer in one application step. Consumption: approx. 1.8 kg/running metre. 3. Application of the primer: ASODUR-GBM is applied pore-clogging in at least one application step. Consumption: min. 300–500 g/m2. 3.1 The freshly applied primer is mixed with fire-dried quartz sand of grain size 0.1–0.6 mm Consumption: approx. 1.0 kg/m2 After the primer has hardened, the unbound quartz sand must be meticulously removed. 4. Contingency position: (Compensation for voids, larger pores and unevenness). The mixed scratch coat (see above) is applied in one application step. Consumption of the finished levelling compound: approx. 1.6 kg/m2 per mm layer thickness

4.1 The still fresh filler is sprinkled with fire-dried quartz sand of grain size 0.1–0.6 mm. Consumption: approx. 0.8–1.0 kg/m2 After the filler has hardened, the unbound quartz sand must be meticulously removed. 4.2 To avoid the formation of bubbles in the following top coat, the scattered scratch coat should be sealed with ASODUR-GBM. Consumption: approx. 0.3–0.5 kg/m2. 4.3 T he still fresh sealing is sprinkled with fire-dried quartz sand of grain size 0.1–0.6 mm. Consumption: approx. 0.8–1.0 kg/m2. After the sealant has hardened, the unbound quartz sand must be meticulously removed. After a waiting time of min. 12 hrs/max. 24 hours, apply the ASODUR-B3311 top coat. 5. Application of the top coat: ASODUR-B3311 is applied in a single application step. Layer thickness: approx. 2.0 mm. Consumption: min. 2.5 kg/m². 5.1 To deaerate the applied ASODUR-B3311 top coat, it is imperative to roll the surface with a spiked roller after a waiting time of approx. 10–15 min. at +20 °C to avoid bubble formation. Important advice: •S CHOMBURG 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. Polyplan/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 rpm. Ensure that air is not mixed in. The temperature of the components should be minimum +15 °C. This also applies to any filler materials that should be mixed in, e.g. sand. Mixing in filler materials should take placed
after the liquid components have been mixed. Then apply the completely mixed material immediately to the prepared substrate and distribute meticulously in accordance with the instructions in the technical data sheets. For applications using the roller method, the use of short pile nylon fur rollers (6 mm) with textured polyamide cover or equivalent is recommended. Always stir 1-component products thoroughly before use. • Higher temperatures shorten the application time. Lower temperatures increase the application and hardening times. The amount of material that is consumed also increases at low temperatures. • Colours: Slight colour differences, caused by different production batches and raw material fluctuations, are unavoidable. Consider this during coating application work. Neighbouring surface sections should be coated using the same production batch (same batch no. on the delivered packaging). • The 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 °C 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. Then apply a complete pore-free new coating. • Synthetic resin products and surface protection systems must be protected from moisture (e.g. rain or condensation water) for approx. 4–6 hours after application. Moisture causes a white colour and/ or stickiness on the surface and can cause problems during curing. Discoloured and/or sticky surfaces must be removed and reworked, e.g. through grinding or shot blasting.
