As a water-repellent, quick-hardening mortar bed when laying natural stone, tiles and boards outdoors and in wet areas <br />such as balconies, terraces, loggias, stairs, swimming pools, intermittently wet rooms, wash bays and water tanks <br />In areas exposed to water, such as swimming pools, areas around swimming pools and public showers or in water impact classes W1-I to <br />W3-I per DIN 18534, in the exterior area on balconies, loggias etc. in accordance with DIN 18531-5 or W1-B to W3-B in accordance <br />with DIN 18535, screed implemented with ASO-EZ4-PLUS should be sealed with a suitable bonded waterproofing system. <br />ASO-EZ4-PLUS is a special cement without trass content. Some regulations, e.g. the VOB DIN 18332, DNV leaflets of the German Natural <br />Stone Association, BIV leaflets of the Federal Association of German Stonemasons, ZDB leaflets published by the Association of German Tile <br />Trades, describe the use of mortars with a high trass content for use in the exterior area/natural stone applications. ASO-EZ4-PLUS uses a <br />more advanced technology which, due to its special properties, has significantly lower “lime efflorescence” than trass mortar. Screed and <br />laying mortar made from ASO-EZ4-PLUS is therefore a special construction method. We therefore recommend that this be contractually <br />agreed.</p> <p>Technical Data <br />Material properties <br />Base material <br />Consistency <br />Grain size max <br />Bulk density of fresh mortar <br />Heating, screed after <br />Flexural strength (28 days, DIN EN 13813) <br />Reaction to fire in accordance with Directive 96/603/EC <br />Compressive strength (28 days, DIN EN 13813)</p> <p>Pre-blended dry mortar <br />Powdered <br />< 4 mm <br />approx. 2.2 kg/dm³ <br />after 3 days <br />≥ 6 N/mm² <br />A1fl <br />approx. 50 N/mm²</p> <p>Mixing <br />Mixing time <br />Water addition</p> <p>approx. 4 - 6 minutes <br />approx. 1.6 l - 2 l</p> <p>Application <br />Substrate temperature <br />Pot life <br />Consumption pro m² and cm layer thickness <br />Mixing method, machines, tools <br />Foot traffic after <br />Ready for covering with tiles <br />Application temperature <br />Overcoat after <br />Hardening time / full resilience</p> <p>approx. 5 - 25 °C <br />approx. 45 minutes <br />approx. 20 kg/m² <br />Forced paddle mixer <br />approx. 6 hours <br />approx. 3 days <br />approx. 5 - 25 °C <br />approx. 3 days <br />approx. 7 days</p> <p>SCHOMBURG GmbH & Co.

For precise information, see the additional Technical Information No. 43.</p> <p>Application <br />Application <br />1. Observe the water addition and avoid excess water! <br />2. Mixing, application, and processing must be completed in immediate sequence. <br />3. The dimensions of surfaces must be such that the application can be completed within this pot life. <br />4. Higher temperatures shorten the pot life. Lower temperatures increase the application and hardening times. <br />5. With bonded screeds, first brush ASOCRET-HB-FLEX into the prepared, e.g. abraded concrete substrate. <br />6. Apply the screed to the wet slurry coat. The relevant guidelines for cement-based screeds after DIN18560 and DIN 18353 apply for <br />processing.</p> <p>Mixing recommendations for mixing and conveying machines <br />1. In conventional mixing and conveying machines with a 220 l mixing vessel, e.g. the Estrich-Boy from Brinkmann, PFT, Putzmeister Mixocret, or <br />similar, a total 250kg of ASO®-EZ4-PLUS is mixed with 16 to 20 l of tap water. This equates to a mixing vessel level of approx. 80% - as <br />recommended by the machine manufacturers in general. <br />2. Half-fill the mixing drum with 125 kg ASO®-EZ4-PLUS and approx. 10 l water. <br />3. Then fill with the remaining 125 kg ASO®-EZ4-PLUS and add 6–10 l water. <br />4. The total mixing time is ca. 4 - 6 minutes.</p> <p>Mixing recommendation for forced paddle mixer <br />1. First provide 100 kg of ASO®-EZ4-PLUS and add 6.4 to 8.0 l of water. <br />2. The mixing time is ca. 4 - 6 minutes. <br />3. Adjust consistency to earth-moist to stiff-plastic by adding water. <br />4. Protect the fresh screed from drying out too quickly (e.g. due to heat or draughts). <br />5. With a water addition of 1.7 litres to 25 kg ASO®-EZ4-PLUS, an ambient and substrate temperature of +23°C, a relative humidity of 50% and a <br />layer thickness of 5 cm, the screed is ready for laying with tiles after three days. <br />6. A moisture measurement must be carried out using the CM method to check the moisture content.</p> <p>Cleaning tools <br />Clean tools thoroughly with water after use.</p> <p>Storage conditions <br />Storage <br />Store in a cool and dry place. Min. 12 months in the original canister. Promptly use opened container.</p> <p>SCHOMBURG GmbH & Co.

(Also <br />see the BEB data sheet “Building climate preconditions for drying screeds”). Tests showed that the crystalline binding of the water is slower at <br />low temperatures (+5 to +10°C), meaning that the screed was only ready to receive tiles after a longer period of time! <br />Water on the surface of the screed indicates excessive water addition! <br />If moisture rises from the substrate, effective waterproofing is essential prior to laying the screed! <br />The installation location must be ventilated. However, draughts and direct solar radiation should be avoided during application and the <br />hardening process. The indoor temperature and floor temperature must be at least +5°C during application, and during the following week! <br />Air dehumidifiers may not be used during the first 3 days! <br />If the selected mixing time is too short or mixing is not sufficiently intense, this is not guaranteed to disperse all constituents sufficiently. A <br />moisture measurement must be carried out using the CM method to assess whether it is ready to receive. <br />Border, field, building separation and movement joints should be carried over to or installed at the designated location; suitable means (e.g. <br />edge strips) should be used to detach them! Crack control joints should be cut in up to a third of the introduced layer thickness! <br />ASO®-EZ4-PLUS can crystalline bind approx. 8% of its weight to water. Water quantities that exceed this volume must evaporate and <br />therefore delay the readiness to receive tiles and boards!</p> <p>Relevant regulations <br />Planning, inspection of substrates and building site circumstances, laying, grouting and subsequent <br />care of the work must be done in accordance with the relevant DIN standards and recognised rules of <br />technology (e.g. the ZDB Data sheets of the Zentralverband Deutsches Baugewerbe e.V.(German <br />construction Association) in the latest version. <br />Observe applicable safety data sheet! <br />GISCODE: ZP1 <br />Explanations <br />Conformity / Declaration / Verification</p> <p>The rights of the buyer with regard to the quality of our materials are based on our terms and conditions of sale and delivery.
