Technical data sheet ASODUR®-B3311 Substrate quality class
Preparing the surface 1. Prime absorbent substrates with ASODUR-GBM in two application steps until pore sealed. 2. Sprinkle the fresh, final priming coat with quartz sand (Ø 0.1-0.6 mm). 3. In case of severe surface irregularities, a scratch coat is applied depending on the roughness depth. (See valid technical data sheet for ASODURGBM)
Application Mixing 1. The (ideal) material temperature during the mixing procedure is +15 °C. 2. Mix the resin homogeneously in the original container. 3. Add the hardener to the resin. 4. The hardener must run completely out of the container. 5. Mix thoroughly with the mixer until a homogeneous consistency. 6. The hardener must be distributed evenly. 7. The mixing time is ca. 3 minutes. 8. Decant the mass into a clean bucket. 9. Stir carefully again. 10. Aggregates are mixed into the ready-mixed and re-potted material. 11. The aggregates must have a material temperature of approx. +15 °C. 12. Quartz sand used must be kiln-dried. 13. For vertical and sloping surfaces we recommend the addition of 1 - 5 wt. - % ASO®-FF. 14. Add ASO®-FF in portions using a suitable stirring device. 15. Stir carefully again.
Application 1. Prime the prepared substrate in the coved fillet area with ASODUR®-GBM. Consumption: approx. 0.04 kg / linear m 2. Create the coved fillets in the still fresh primer in one application step with the coved fillet mortar ASODUR®-EMB. Consumption: approx. 1.8 kg / linear m 3. Apply the primer ASODUR®-GBM in at least one application step to close the pores. 4. Sprinkle the still fresh primer with oven-dried quartz sand (Ø 0.1–0.6 mm). Consumption: approx. 1 kg/m². After the primer has hardened, the unbound quartz sand must be meticulously removed. 5. To even out voids, larger pores and unevenness, apply the mixed scratch filler (see above) in one application step. 6. Scattered the still fresh trowelling with fire-dried quartz sand (Ø 0.1–0.6 mm). After the filler has hardened, carefully remove the unbound quartz sand. 7. To avoid bubble formation in the subsequent top coat, seal the scratch coat with ASODUR®-GBM. 8. The still fresh seal is sprinkled with fire-dried quartz sand (Ø 0.1-0.6 mm). After the sealing has hardened, carefully remove the unbound quartz sand. 9. After a waiting time of ≥ 12 hours / ≤ 24 hours, the top coat ASODUR®-B3311 can be applied. 10. Apply ASODUR®-B3311 in one application step in a layer thickness of approx. 2.0 mm. Consumption: approx. 2.5 kg/m² 11. To ventilate the applied 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 (prevention of bubble formation).
Cleaning tools Clean tools immediately after use with ASO-R001.

Technical data sheet ASODUR®-B3311 Storage conditions Storage Store in a frost-free, cool and dry place. 18 months in the original canister. Promptly use opened container.
Disposal Hardened product leftovers can be disposed of in accordance with disposal code AVV 15 01 06.
Notes Higher temperatures shorten the pot life. Lower temperatures increase the application and hardening times. The rate at which material is consumed also increases at lower temperatures. Slight colour differences, caused by different production batches and raw material fluctuations, are unavoidable. 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 roughened. Then apply a complete pore-free new coating. After they have been applied, surface protection systems must be protected against dampness (e.g. rainwater, condensation water) for approx. 4–6 hours. Moisture causes a white colour and/or stickiness on the surface and can cause problems during 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 textured surface roughness and absorbency, level compensation and residual material in the container. We always recommend a calculated safety addition of 10% on top of the calculated consumption quantities. The surface can be scratched by exposure to grinding abrasion. Particularly visible with dark shades. This will not have a negative impact on proper functioning. In order to maintain the surface quality and appearance in the long term, regular care of the surface with suitable cleaning materials and care products is recommended. Applications that have not been clearly mentioned in this technical data sheet may only be carried out after the technical service department of SCHOMBURG GmbH has been consulted, and after the said department has approved of such a course of action in writing. Observe the technical data sheets of the products mentioned before starting work.
Relevant regulations The recognised standards of construction engineering, the relevant guidelines and current regulations must be observed. Observe applicable safety data sheet! GISCODE: RE 30
