• Water emulsified, pigmented, 2-comp. epoxy resin. • Free from organic solvents. • Low odour. • Resistant to dilute alkalis and acids, heating oil and petrol. • Can be diluted up to 10% with water (priming). • Water vapour permeable. • Excellent adhesion to to many substrates. • Satin-sheen surface finish. • Water resistant. • Resistant to plasticizers. • Can be produced as an anti-slip finish. When exposed to UV, colour variations – related to the binder – as well as chalking must be anticipated. Permanent exposure to weathering and permanent exposure to wet conditions is to be tested on an individual basis.

Substrate preparation: The area to be treated must be: • dry, firm, sound and have a good key • free from separating and adhesion inhibiting substances such as dust, laitance, grease, oil, rubber marks, paint residues and similar
Calcium sulfate screed: • Screed quality: DIN EN 13813 CA-C25-F5 • Age: min. 14 days • Tensile adhesion strength: > 1.0 N/mm² • Residual moisture: < 0.5% (carbide hygrometer method) with underfloor heating < 0.3 % (carbide hygrometer method)
Dependent on the condition of the substrate to be treated, use suitable preparation methods e.g. shot blasting, scabbling, planing, brushing, sweeping, vacuuming, grit blasting, high pressure washing. Seal existing cracks (e.g. with ASODUR-K900 in accordance with the technical data sheet).
Mastic asphalt screed: • Screed quality: AS IC15 • Tensile adhesion strength: > 1.0 N/mm²
The following criteria are also to be observed dependent on the particular substrate: Cementitious surfaces: • Concrete: min. C20/25 • Screed quality: DIN EN 13813 min. CT-C35-F5 • Age: min. 28 days • Tensile adhesion strength: 1.5 N/mm2 • Residual moisture: 6% (carbide hygrometer method) • Render quality: P III a / P III b • Tensile adhesion strength: approx. 0.8 N/mm² (pre-blended mortar) • Residual moisture: 6% (carbide hygrometer method)
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. Blend both 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 approx. 5 minutes. The minimum 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.
Magnesia screed: • Screed quality: • Age: • Tensile adhesion strength: • Residual moisture:
Method of application / consumption: Apply 2-3 coats of ASODUR-V360W by roller. Pour the mixed material in portions over the area and spread using a twin-bladed rubber squeegee. Then even out using a short nap paint roller in a 90º crossways manner.
DIN EN 13813 min. MA-C35-F5 min. 14 days > 1.0 N/mm2 < 2 % (carbide hygrometer method)
Priming: Dilute ASODUR-V360W with 8 to a max. of 10% water and apply by roller in one coat (crossways at 90º). Consumption: approx. 300 g/m2 of diluted material.

Important advice: • Avoid applying individual coats too thickly (greater material consumption). This leads to crack formation, possibly de-lamination and to extended waiting times between individual applications. • Ensure there is good ventilation during the drying and curing phases. • As a rule SCHOMBURG products are supplied in working packs i.e. at a predetermined mixing ratio. With deliveries in large containers, part quantities will need to be weighed using scales. Always thoroughly stir the filled components and only then blend with the second component. This is to be carried out with a suitable rotary mixer e.g. Polyplan/Ronden mixing paddle or similar. In order to exclude mixing errors, decant into a clean container and remix. The mixing speed should be 300 – 400 rpm. Ensure that no air is entrained. Higher speeds drag unnecessary air quantities into the product whilst lower speeds do not result in a good blend or require too long a mix time (pot life). The temperature of the components should be at a minimum of +15° C. This is also applicable to any fillers, e.g. sand, to be mixed in. The addition of any fillers is carried out after both liquids have been blended. Afterwards tip the completely mixed material immediately onto the prepared substrate and promptly thoroughly spread in accordance with the instructions in the technical data sheet. Always stir one component products before using. • Higher temperatures shorten the pot life. Lower temperatures increase the pot life and curing time. Material consumption is also increased at lower temperatures. • Colour: Minor colour variations due to different production plants and raw material fluctuations are unavoidable. This should be considered when applying coatings. Neighbouring sections should be completed with the same production units (see batch number on the packaging).
Possible situation - levelling /scratch coat: Produce the levelling/scratch coat: ASODUR-V360W: 1.0 part by weight Quartz sand (particle size 0.1–0.35 mm) 0.5 parts by weight Mix in the quartz sand with the previously homogenously mixed and decanted resin and hardener components. Ensure that the liquid and solid constituents are evenly blended. Levelling layer and scratch coat: Apply the finished mix in a single operation on the primed surface to a thickness of max. 2 mm using scratch coat techniques. Treat uneven areas as necessary, once cured, with 100 grade abrasive paper without leaving grooves, and vacuum. Once hardened, seal the area with ASODUR-V360W. The consumption dependent on substrate condition is approx. 1.6 kg/m²/mm thickness. Drying time: 1 – 2 days/mm. Recesses and pinholes are to be closed off with ASODUR-V360W with the addition of 2–3% by weight of the fibre filler ASO-FF. A second layer can be applied, if needed, after waiting for approx. 2 hours. Finishing sealer: ASODUR-V360W is roller applied (crossways at 90º) in 1–2 coats on to the primer or scratch coat. Consumption: approx. 300–350 g/m2/coat Possible situation - slip prevention: Apply one coat of ASODUR-V360W. Homogenously stir in ASO-Antislide (10% by weight), then thoroughly and evenly apply the mix with a short nap paint roller crossways at 90º. Keep overlap areas as small as possible. Consumption: a pprox. 140 – 170 g/m² plus 14 – 17 g/m² ASO-AntiSlide

• The bond between the individual coats can be heavily impeded through the influence of moisture or contamination between successive applications. The substrate temperature must be a min. of < 3° C above the dew point. • If there is a long time period between coatings or if areas need to be re-coated after a long time period, then the old surface must be well cleaned and thoroughly abraded, after which a completely new pore free sealing coat should be applied. It is not sufficient to simply overcoat. • Surface protective systems must be protected for approx. 4 – 6 hours from dampness after application (e.g. rain, melt water). Dampness produces a white discolouration and/or stickiness on the surface and can impede the cure. Discoloured and/or sticky surfaces should be taken off e.g. by abrading and renewed. • 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 that are not clearly explained in this technical data sheet may only be carried out after consultation with and written confirmation from the Technical Services Department of SCHOMBURG. • Cured product residues are to be disposed of under waste disposal classification AVV 150106. Please observe a valid EU safety data sheet. GISCODE: RE 2
