Consult current technical data sheet for most recent information.</p> <p>* Values relate to +23° C room temperature and 65% relative humidity. <br />**) R eadiness to receive finishes to be determined by the carbide (CM) method <br />(see technical data sheet)</p> <p>2 05527</p> <p>Product preparation: <br />For mixing we recommend the use of suitable mechanical equipment, batch <br />mixers, screed mixers with a 65 mm pipe diameter or other conventional <br />screed mixers e.g. PFT, Putzmeister Mixocret or similar. Pay attention to the <br />moisture content of the aggregate and avoid excess water. The working <br />time is approx. 60 minutes at +20° C. Mixing, application and finishing <br />must follow each other swiftly. Only measure out areas that can be <br />completed within this working time. For bonded screeds firstly brush <br />ASOCRET-HB-flex onto the prepared, e.g. mechanically abraded, concrete <br />substrate. Lay the screed into the wet slurry coat. Watch the moisture <br />content of the aggregate and avoid excess water!</p> <p>ASO®-EZ4 <br />Water repellent <br />special cement</p> <p>Properties: <br />• High strength <br />• Protects against efflorescence <br />• Fibre reinforced <br />• Rapid setting <br />• Long working time <br />• Foot traffic after <br />approx. 6 hours* <br />• Permits early installation of tiles <br />• For interior and exterior use <br />• Can be heated to recognised <br />technical regulations <br />after 3 days</p> <p>1 Filling the screed machine with aggregate</p> <p>2 Adding the screed binder at the correct <br />mix ratio to the aggregate</p> <p>3 Adding the defined water quantity, <br />caution – mix time!</p> <p>4 Pumping the screed mix</p> <p>5 Compacting the screed mortar</p> <p>6 Striking off the screed mortar with a <br />suitable straightedge</p> <p>Consumption of ASO®-EZ4 in kg/m²: <br />Mixing ratio, parts by weight <br />Screed thickness, cm</p> <p>1: 4**)</p> <p>1: 5**)</p> <p>1</p> <p>4.1</p> <p>3.4</p> <p>4</p> <p>16.3</p> <p>13.6</p> <p>5</p> <p>20.4</p> <p>17.0</p> <p>6</p> <p>24.4</p> <p>20.4</p> <p>**) 1 <br /> : 4 parts by weight equal to approx. 1: 2.7 parts by volume <br />1:5 parts by weight equal to approx. 1: 3.3 parts by volume <br />Application as a bedding mortar: <br />ASO®-EZ4 to a mix ratio of 1 : 3 by volume (equates to 1 : 4.5 parts by <br />weight) with aggregate (of particle size 0–4 mm diameter) in a suitable <br />compulsory mixer. Minimum mix time 4–5 minutes. <br />Mixing and application recommentations for water <br />permeable drainage mortars (also known as single grain <br />mortars, mono grain mortars or drain mortars): <br />ASO®-EZ4 mix ratio: mix 1: 3 by volume (equates to approx. 1 : 4 parts by <br />weight) with aggregate without fines e.g. granite chippings of grain size <br />2/5 mm, 5/8 mm, 8/12 mm, or pea gravel of grain size 4/8 mm with <br />approx. 7.5 to 9 l water per 25 kg ASO®-EZ4 in a suitable mixing machine. <br />Only add enough water to the fresh mortar until a damp earth consistency is <br />achieved. (Refer to technical data sheet for exact mixing information). <br />Mixing recommendations for mixing and rotary feed <br />machines: <br />For a 220 l mixing drum mix a total of 200 kg aggregate with 50 kg <br />ASO®-EZ4. First half fill the mix vessel with aggregate 0/8 (approx. 15 <br />shovels at 7 kg), approx. 5-6 litres of water and 50 kg of ASO®-EZ4 and <br />mix to a plastic consistency for 2 minutes Then fill the mixing vessel with the <br />rest of the aggregate (dependent on the mixing ratio another 15 shovels at <br />7 kg) and the remaining water. Dependent on the moisture content of the <br />aggregate a total of approx. 10 – 20 litres of water will be necessary. The <br />latter value relates to dry aggregate. In general 0/8 aggregate has a <br />moisture content of approx. 4%, therefore 8 litres of water are already <br />contained in 200 kg of aggregate. Keep to a total mix time of 4 minutes <br />as only then are all components dispersed and the final consistency <br />achieved. <br />Protect the fresh screed from drying out too quickly e.g. through heat or <br />drafts. The screed is ready to take tiled finishes after three days when <br />installed at 5 cm thick when the ambient and substrate temperatures are at <br />+23 °C and the relative humidity is 50% and when the mixing ratio is 1:4 <br />parts by weight and dry aggregate is used with a particle size distribution <br />between A8-B8 closer to B8 with consistent grading and with a water</p> <p>7 Rubbing up and finishing the screed <br />surface</p> <p>addition of 17 litres per 50 kg ASO®-EZ4. <br />Confirmation should be sought by measuring the moisture content with a <br />carbide hygrometer (CM). For screeds that need to conform to a particular <br />screed quality in accordance with DIN EN 13813, performance tests will <br />be required. These are to be carried out prior to commencing work.</p>
