Product preparation: Components A (resin) and B (hardener) are delivered at a predetermined mixing ratio. Tip component B into component A. Ensure that the hardener drains completely from its container. Mix the components together with a suitable mixer at approx. 300 rpm (e.g. drill with paddle). It is important to also stir from the sides and the bottom to ensure that the hardener is evenly dispersed. Stir until the mix is homogenous (free from streaks); mixing time 3 minutes. The material temperature during mixing should be +15°C. Do not use mixed material directly from the packaging! Decant the material into a clean container and mix through thoroughly once again. When mixing in aggregates (e.g. ASO-Antislide), ensure that the aggregate is dry and is also at a temperature of approx. +15 °C.
Consumption: absorbent substrates: approx. 110–160 g/m² non-absorbent substrates: approx. 55–70 g/m²
Important advice: • As a rule, SCHOMBURG products are supplied in working packs i.e. supplied at a coordinated mix ratio. When supplied in large containers, part quantities must be weighed out using a balance. Always thoroughly stir the filled components and only then mix with the second component. This is to be executed with a suitable stirrer e.g. Polyplan/Ronden mixing paddle or similar. In order to exclude mixing errors, decant into a clean container and mix anew. The mixing speed should be approx. 300 rpm. Ensure that no air is mixed in. The temperature of the components should be minimum +15°C. This is also valid for any potential fillers to be mixed, e.g. sands. The addition of the fillers is only to occur once both liquid components have been blended. Afterwards place the completely mixed material immediately on to the prepared substrate and quickly and carefully spread out in accordance with the instructions in the technical data sheet. For applications by roller, it is recommended to use a short nap nylon paint roller (6 mm) with a textured polyamide cover or similar. Always thoroughly stir one component products before use. • Too great a thickness (more material consumption) leads to an uneven matt effect, crack formation and de-lamination. • Higher temperatures shorten the pot life. Lower temperatures increase the pot life and setting time. Material consumption is also increased at lower temperatures. • Colours: Small variations in colour, resulting from varying production batches and raw material fluctuations, are unavoidable. When applying coatings, take this into consideration. Carry out neighbouring
Method of application / consumption: Smooth: Apply ASODUR-V2250 in one coat. Pour the mixed material over the floor in sections and spread with a solvent resistant rubber bladed squeegee and subsequently roll thoroughly and evenly with a short napped fur roller or surface leveller. Keep areas of overlap to a minimum. Consumption: Porous substrates: approx. 100–150 g/m2 Non-porous substrates: approx. 60–80 g/m2 Anti-slip: The mixed ASODUR-V2250 is supplemented by homogenously stirring in approx. 8–10% by weight of ASO-Antislide. Place the mixture in portions over the surface, spread with a solvent resistant twin-bladed squeegee and then thoroughly and evenly apply and smooth out using a short nap paint roller in a criss-cross manner. Keep overlap areas as small as possible. ASO-Antislide addition: approx. 8–10% by weight

• Consumption quantities given are values determined by calculation without additions for surface roughness or absorption, levelling or residues in the containers. We recommend adding a calculated safety factor of 10% to the computed consumption quantities. • Applications, which are not clearly mentioned in this technical data sheet may only be implemented after consultation with and written confirmation from the technical service department of SCHOMBURG. • Cured product residues can be disposed of using waste disposal code AVV 150106.
sections with the same production batch (same batch number on the packaging). • The bond between individual coats can be heavily impeded by the penetration of moisture and contamination between the individual coats. Coating work requires a substrate temperature of at least 3°C above the dew point temperature. • If there is a long down time between individual coats or if already treated areas are to be renewed with liquid resins after a long period of time, then the old surface is to be well cleaned and thoroughly abraded. Afterwards carry out a completely new pinhole free coating. • Surface protection systems must be protected from moisture (e.g. rain, melt water) after their application for approx. 4-6 hours. Moisture produces a white discolouration and/or stickiness on the surface and can lead to interference in the curing process. Take off discoloured and/or sticky surfaces by e.g. planing or abrasive blast techniques and renew.

All data has been determined under laboratory conditions at +20°C. Deviations are possible due to high temperatures, local factors and environmental conditions. Slight optical surface changes or minor swelling, which does not affect the functionality of the coating, cannot therefore be precluded. Where doubt exists, we recommend that project related suitability trials are carried out. This technical data sheet is a translation from German and does not consider local building codes or legal requirements. It shall be used as general reference for the product. Legally binding is only the latest German technical data sheet or the latest data sheet from one of our foreign subsidiaries inside their sales territory.
