Use opened <br />packaging promptly. <br />Consumption: approx. 20 kg ASO-EZ4-PLUS <br />per m2/cm screed thickness <br />Packaging: <br />25 kg bag <br />Cleaning: Clean tools and equipment <br />immediately with water. <br />Classification: <br />EN 13813 CT-C50-F6-A9 <br />Fire rating: A1 in accordance with <br />resolution 96/603/EG <br />Foot traffic after*: <br />approx. 6 hours <br />Fully cured after*: <br />approx. 7 days <br />Working time*: <br />approx. 45 mins</p> <p>Areas of application: <br />ASO-EZ4-PLUS is a fibre reinforced special cement for the <br />production of water repellent cementbased screeds <br />and mortars that permits coverings to be installed early. <br />Due to their water repellent properties, screeds and <br />mortars produced with ASO-EZ4-PLUS offer increased <br />protection against frost damage and efflorescence. As a <br />water repellent, rapid setting mortar bed when installing <br />natural stone and tiles externally and in wet areas such as <br />balconies, terraces, loggia, stairwells, swimming pools, <br />damp environments, car washes and water containers. <br />Screeds produced with ASO-EZ4-PLUS are suitable as <br />either bonded, unbonded, floating or heated screeds,</p> <p>1/3</p> <p>05/18</p> <p>First half fill the mix vessel with 125 kg of ASO-EZ4-PLUS <br />and approx. 10 litres water. Then fill with the rest of the <br />125 kg of ASO-EZ4-PLUS and 6 – 10 litres of water. <br />Keep to a total mix time of approx. 4 minutes as only then <br />can all components be dispersed and the final consistency <br />achieved.</p> <p>Application/substrate temp: +5 °C to +25 °C <br />*Values relate to +23° C and 50% relative humidity. Higher temperatures <br />reduce and lower temperatures lengthen these given times.</p> <p>Minimum nominal thickness to DIN 18560: <br />Beneath tiles</p> <p>40 mm on insulation or <br />separating layer</p> <p>Beneath parquet, carpet, <br />linoleum or PVC</p> <p>30 mm on insulation or <br />separating layer</p> <p>In general</p> <p>10 mm bonded</p> <p>Mixing recommendation for batch mixers <br />(z. B. INOTEC MIX120 PLUS): <br />Firstly put 100 kg ASO -EZ4-PLUS into the mixer and add <br />6.4 to 8.0 l water. Then mix for 4 minutes. Adjust to a <br />damp earth to stiff plastic consistency via the addition of <br />water. <br />Protect the fresh screed from drying out too quickly e.g. <br />from heat or drafts. Screeds are ready to receive tiled <br />finishes after 3 days with a water addition of 1.7 litres <br />per 25 kg ASO-EZ4-PLUS, an ambient and substrate <br />temperature of +23° C, a relative humidity of 50% and <br />a thickness of 5 cm. Confirmation should be sought by <br />measuring the moisture content with a carbide hygrometer.</p> <p>Product preparation: <br />For preparation we recommend using the Brinkmann <br />screed boy with a 65 mm hose diameter, or other <br />conventional screed mixers PFT, Putzmeister Mixocret <br />or similar. Pay attention to the water addition and avoid <br />excess water. The working time is approx. 45 minutes at <br />+20° C. Mixing, application and finishing must follow <br />each other swiftly. Only measure out areas that can be <br />completed within this working time. Higher temperatures <br />reduce and lower temperatures lengthen the working <br />time and setting time. With bonded screeds first brush <br />ASOCRET-HB-FLEX into the mechanically abraded <br />concrete substrate. Lay the screed into the wet slurry coat. <br />The general regulations for cement-based screeds <br />DIN 18560 and 18353 should be followed for screed <br />laying.</p> <p>Important advice: <br />• Please refer to the technical data sheets for the <br />products mentioned above! <br />• When too short a mix time is selected or the material is <br />not mixed intensively enough then the dispersion of all <br />components is not guaranteed. Early installation of floor <br />finishes and high strength is no longer given! <br />• The determination of the screed’s readiness to receive <br />floor finishes should be carried out using a carbide <br />hygrometer. Keep to the limiting values (see table 1). <br />• Low temperatures, high humidity and deep thicknesses <br />retard the hardening, drying and the speed at which <br />the screed is ready to receive finishes (also see the <br />BEB data sheet on building climate requirements for the <br />drying of screeds). <br />• Trials have shown that at lower temperatures (+5° C <br />to +12° C) the binding of the water proceeds at a <br />strongly delayed rate so that the readiness to receive</p> <p>Mixing recommendations for mixing and rotary feed <br />machines: <br />In a conventional mixing machine with rotary feed with <br />a 220 litre mix capacity e.g. Brinkmann screed-boy, PFT, <br />Putzmeister Mixocret or similar mix together a total of <br />250 kg ASO-EZ4-PLUS with 16 – 20 litres water. This <br />relates to a mixer capacity of approx. 80% - which is <br />generally recommended by the equipment manufacturers. <br />Observe the following procedures:</p> <p>2/3</p> <p>05/18</p> <p>Important advice table 1: <br />Maximum moisture content of the screed determined with a carbide hygrometer <br />Floor finish</p> <p>heated</p> <p>unheated</p> <p>Vapour impervious finishes</p> <p>1.8 %</p> <p>2.0 %</p> <p>Vapour barrier</p> <p>1.8 %</p> <p>2.5 %</p> <p>Vapour permeable</p> <p>2.0 %</p> <p>3.0 %</p> <p>Parquet</p> <p>1.8 %</p> <p>2.0 %</p> <p>Laminate flooring</p> <p>1.8 %</p> <p>2.0 %</p> <p>thick-bed</p> <p>2.0 %</p> <p>2.0 %</p> <p>thin-bed</p> <p>2.0 %</p> <p>2.0 %</p> <p>Textile finishes</p> <p>Ceramic tiles or natural stones/ <br />concrete slabs</p> <p>The measurements with the carbide hygrometer are to be carried out in accordance with the current working instructions of the FBH-AD from the <br />technical information “coordination of cut out areas with heated floor construction”.</p> <p>• The relevant current regulations are to be observed. <br />E.g. <br />DIN 18157, DIN 18352, DIN 18531 to 18535, <br />DIN 18560, DIN EN 13813, DIN 1055 <br />The BEB data sheets distributed by the National <br />Association for Screeds and Finishes. <br />The technical information “coordination of cut out areas <br />for heated floor constructions”. <br />The ZDB data sheets distributed by the Technical <br />Association of the German Tile Industry. <br /> [*1] Bonded waterproof membrane <br /> [*2] Mechanically heavy-duty ceramic floor finishes <br /> [*3] Movement joints in tiled finishes <br /> [*5] C <br /> eramic tiles, slabs, natural stone and concrete <br />blocks on cement-based screeds over insulation <br /> [*6] C <br /> eramic tiles, slabs, natural stone and <br />concrete blocks on heated cement-based floor <br />constructions <br /> [*7] Tiled finishes on the exterior of buildings</p> <p>floor finishes is achieved later. <br />• Water that bleeds to the surface indicates too much <br />water (more than 2 litres of water per 25 kg <br />ASO-EZ4-PLUS)! <br />• ASO-EZ4-PLUS can bind up to approx. 8% of its weight <br />of water in a crystalline way. Anything above this <br />level has to evaporate and consequently delays the <br />readiness to receive finishes! <br />• Where rising dampness is present a functioning damp <br />proof membrane is necessary prior to the installation of <br />the screed! <br />• Ventilation is necessary on the building site. The interior <br />and floor temperature must be a minimum of +5°C <br />during installation and for one week afterwards. <br />De-humidifiers may not be used in the first 3 days! <br />• Do not add any cement or other binders! <br />• Perimeter, bay, construction and movement joints are to <br />be carried through or incorporated in the designated <br />position and composed of suitable material e.g. <br />edging strip. Crack control joints are to be cut into the <br />top third of the installed screed. <br />• Do not add any additives or other materials.</p> <p>Please observe a valid European safety data sheet! <br />GISCODE: ZP1</p> <p>This technical data sheet is a translation from German and does not consider local building codes or legal requirements.
