Due <br />to their water repellent properties, screeds and mortars <br />produced with ASO-EZ4-Plus offer increased protection <br />against frost damage and efflorescence. As a water <br />repellent, rapid setting mortar bed when installing natural <br />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, <br />whether as a wearing finish or as a substrate for tiles, <br />slabs or natural stone. For installation the general <br />regulations for cementitious screeds DIN 18560 and <br />DIN 18353 apply. The substrate must be able to take <br />the loading according to DIN 1055. <br />In duty wet areas falling under the wet area <br />classifications (FBK) 0, A02, B0 according to the ZDB <br />Worksheet [*1], produce screeds with ASO-EZ4-PLUS <br />and the proper SCHOMBURG waterproofing system. <br />In wet areas under the classifications A2, B and C <br />according to general building codes, such as swimming <br />pools and pool decks and public showers, produce <br />screeds with ASO-EZ4-PLUS and the proper <br />SCHOMBURG waterproofing system.</p> <p>Technical Data:</p> <p>Basis: <br />special cement, additives, <br /> aggregate <br />Colour: <br />grey <br />Water addition: <br />1.6–2.0 l/25 kg ASO-EZ4-Plus <br /> <br />(semi-dry consistency - stiff-plastic) <br />Mix method: <br />Forced paddle mixer, <br /> <br />free fall mixer <br />Bulk density <br />of fresh mortar: <br />approx. 2.2 kg/dm3 <br />Storage: 12 months when stored dry in the <br />original unopened packaging. Use <br />opened packaging promptly. <br />Consumption: <br />approx. 20 kg ASO-EZ4-Plus <br /> <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: <br />A1 in accordance with <br /> <br />resolution 96/603/EG <br />Traffic after*): <br />approx. 6 hrs <br />Fully cured after*): approx. 7 days <br />Working time*): <br />approx. 60 mins <br />Application/ <br />substrate temp: <br />+5 °C to +25 °C <br />*) Values relate to +23° C and 65% relative humidity.

Pay attention to the water addition and avoid <br />excess water. The working time is approx. 60 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 <br />coat. The general regulations for cement-based screeds <br />DIN 18560 and 18353 should be followed for screed <br />laying. <br />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, <br />PFT, Putzmeister Mixocret or similar mix together a total <br />of 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: <br />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 <br />then can all components be dispersed and the final <br />consistency achieved. <br />Mixing recommendations for a free-fall mixer: <br />First add 4 litres of water, 100 kg ASO-EZ4-Plus and a <br />further 2.5 – 4.0 litres of water. Subsequently mix for 5 <br />minutes and adjust the consistency with the addition of <br />water from semi-dry to stiff plastic. <br />Protect the screed from drying out too quickly e.g. from <br />heat or drafts. Screeds are ready to receive tiled finishes <br />after 3 days with a water addition of 1.7 litres per <br />25 kg ASO-EZ4-Plus, an ambient and substrate</p> <p>temperature of +23° C, a relative humidity of 50% <br />and a thickness of 5 cm. Confirmation should be sought <br />by measuring the moisture content with a carbide <br />hygrometer. <br />Important advice: <br />• Instead of using ASOCRET-HB-flex, an alternative slurry <br />bonding coat can be produced using ASOPLAST-MZ <br />diluted 1:2 with water and a screed mortar composed <br />of 25 kg ASO-EZ4-Plus and 5 kg ASO-EZ4. <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 />• Lower temperatures, high humidity and thick screeds <br />delay the setting, drying and achievement of readiness <br />for laying finishes (see also the BEB data sheet <br />“climatic requirements for the 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 <br />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 <br />interior and floor temperature must be a minimum of <br />+5°C during installation and for one week afterwards. <br />De-humidifiers may not be used in the first 3 days!</p> <p>2/3</p> <p>25/15</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 <br />FBH-AD from the technical information “coordination of cut out areas with heated floor construction”.</p> <p>•D <br /> o not add any cement or other binders! <br />• P erimeter, bay, construction and movement joints <br />are to be carried through or incorporated in the <br />designated position and composed of suitable <br />material e.g. edging strip.
