In conventional mixing and conveying machines with a 220 l mixing vessel, e.g. Estrich-Boy from Brinkmann, a total 200kg of aggregate is mixed <br />with 50 kg ASO®-EZ4. This equates to a mixing vessel level of approx. 80% - as recommended by the machine manufacturers in general. <br />2. Half-fill the mixing drum with aggregate with a grain size 0/8 (approx. 15 scoops of 7 kg each), add approx. 5—6 l water and 50 kg ASO®EZ4. Mix for approx. 2 minutes for a plastic consistency. <br />3. Add the remaining aggregate to the mixing drum and then the remaining water. <br />4. Depending on the aggregate moisture, a total of approx. 10-20 l water is required. The latter value relates to dry aggregate. In general, <br />aggregate with a grain of 0–8 has a moisture content of approx. 4%, therefore 8 l of water is already contained in 200 kg of aggregate but the <br />quantities do fluctuate. <br />5. It is imperative to comply with the total mixing time of 4 minutes, as all components are only decomposed after this time and the final consistency <br />is formed.</p> <p>Mixing recommendation for mortar <br />1. Mix ASO-EZ4 at a mix ratio: 1: 3 parts by volume (equates to approx. 1: 4.5 parts by weight) with aggregate (Ø 0–4 mm) in a suitable forced <br />paddle mixer. <br />2. The mixing time is at least 4 minutes! <br />3. Protect the fresh screed to prevent it drying out too rapidly (e.g. due to heat or draughts). <br />4. Tiles are ready for laying after 3 days if the following prerequisites are met: * Mix ratio of 1:4 parts by weight * Dry aggregate (DIN 4226; <br />grading curve A8 - B8 close to B8; constant grading) * Water addition of 17 litres on 50 kg ASO-EZ4 * Ambient and substrate temperature: <br />+23 °C * Relative humidity of 50% * Layer thickness of 5 cm <br />5. A moisture measurement must be carried out using the CM method to check the moisture content. In the case of screeds that are required to <br />satisfy a certain screed quality in accordance with DINEN13813, a performance test is necessary. This must be performed before starting the <br />work.</p> <p>Mixing drainage mortar <br />1. Fill ASO-EZ4 and the aggregate into a suitable screed mixer at a mix ratio of 1:1 parts by volume. <br />2. Add water and mix for 4 to 5 minutes depending on the screed mixer, until a viscous mortar is achieved. <br />3. Add the remaining 2 parts by volume of aggregate and mix until a homogeneous, semi-dry consistency is reached. The consistency is correct <br />once the mortar falls apart again after rolling it into a ball. Drainage mortar that has been mixed too damp loses its drainage capability, as the <br />voids between the grains are closed with binder paste! <br />4. Lay natural stone, concrete or ceramic boards properly in the drainage mortar.</p> <p>Instructions for mixing drainage mortar <br />1. ASO-EZ4 is mixed at a ratio of: 1:3 parts by volume (equates to approx. 1: 4 parts by weight) with the aggregate (without fine grain parts) in a <br />suitable screed mixer. Double-crushed chips with grain sizes of ø 2/5 mm, ø 5/8 mm, ø 8/12 mm, or pea shingle with ø 4/8 mm are used as <br />the aggregate. Choose the aggregate based on the required mortar bed thickness and availability. <br />2. The water addition must be varied based on the aggregate moisture. When using dry aggregates, approx. 30—36 weight % of water are <br />required based on the ASO-EZ4 addition. Example: 7.5—9 l of water per 25 kg of ASO-EZ4. The low water requirements of the aggregates <br />used result in very low w/c ratios. The pot life reduces to around 20–40 minutes when producing drainage mortar. Only add water to the fresh <br />mortar until a semi-dry consistency is reached. <br />3. The minimum thickness for the mortar bed must be predetermined to the expected payloads depending on the aggregate used and the overall <br />structure. Ensure that the foundation has sufficient drainage.</p> <p>Drainage screed on a separating layer on load-bearing concrete slabs <br />1. Apply a drainage mat to the waterproofed and bearing substrate. <br />2. Insert the drainage mortar with a semi-dry consistency and compact slightly. Insert the edge profiles and strike off to the intended height level. <br />Minimum film thickness: 5 cm but at least 5 times the largest grain used. Ensure that the drainage layer has sufficient drainage! Adequate falls (at <br />least 1 - 2%) must be provided in the application substrate and on the covering surface. <br />3. Insert the boards that have been coated with ASOCRET-HB-FLEX on the rear into the freshly applied mortar bed and tap them in. <br />4. Grout with CRISTALLFUGE-PLUS, CRISTALLFUGE-FLEX or CRISTALLFUGE-HF after at least 3 days depending on the covering.</p> <p>Laying tiles and boards on hardened drainage screed <br />1. Lay the natural stone or ceramic covering in the thin or medium bed on the drainage screed that has been scraped off to the intended height <br />level, rubbed down slightly, smoothed and hardened. Apply with CRISTALLIT-FLEX, CRISTALLIT-MULTI-FLEX or LIGHTFLEX, which must all be <br />hardened with UNIFLEX-F. <br />2. After the thin/medium mortar bed has hardened, grout with CRISTALLFUGE-PLUS, CRISTALLFUGE-FLEX or CRISTALLFUGE-HF.</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 mixing water is <br />slower at low temperatures (+5 to +10 °C), meaning that the screed was only ready to receive tiles after a longer period of time! <br />Water that is pressed out of the surface of the screed indicates excessive water or aggregate addition (more than 3.3:1 volume parts, <br />equates to approx. 5:1 parts by weight), an incorrect grading curve or inadequate mixing. A consequence of this will be a crumbling <br />surface! <br />The quality of the aggregate used partly affects the properties of the screed produced. The aggregate must not contain any harmful and <br />staining components. Aggregate in accordance with DIN 4226 should be used with a constant grading curve between A and B (close to B) <br />according to DIN 1045. If aggregates with other grain distributions are used, a greater quantity of binder may be required. Aggregates with <br />a grading curve between B and C according to DIN 1045 require a higher proportion of ASO®-EZ4. The grain size distributions that <br />should be used with different layer thicknesses are available in the "Layer thickness in accordance with grading curve" table. <br />If the surface of the screed cannot be closed sufficiently when rubbed, this indicates that the proportion of fines in the aggregate is too low. A <br />higher quantity of ASO®-SEB is required to replace the missing proportion of fine grain! <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. The <br />screed will not be ready to receive tiles and boards quickly, and it will no longer exhibit a high strength! <br />Border, field, structural movement joints and movement joints should be carried over to or installed at the designated location; suitable <br />means, e.g. 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 />Instead of ASOCRET-HB-FLEX, bonding slurry made of ASOPLAST-MZ at a ratio of 1: 1-2 can be diluted with water and screed mortar <br />made of 1 RT ASO®-EZ4 and 2 RT aggregate Ø 0–4 mm can be used! <br />We recommend the ASO®-EZ4-PLUS pre-blended dry mortar to lay tiles, boards and pool edging stones in a thick layer. <br />If more water is added than required to achieve the stiff or stiff plastic consistency, the excess water cannot be bound and must evaporate. <br />The screed will then be ready to receive tiles later! <br />ASO®-EZ4 already contains fibres. If additional fibres are added, this can cause the screed to be ready to receive tiles later! <br />For use in areas with inadequate aggregate quality or where storage of the mortar components is not possible or desirable, the ASO®-SEM <br />/ ASO®-EZ4-PLUS pre-blended dry mortars are available! <br />If moisture rises from the substrate, effective waterproofing is essential prior to laying the screed! This does not apply in conjunction with <br />coatings in the drainage mortar on an unbound cementitious base layer.</p> <p>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 sheets of the Zentralverband Deutsches Baugewerbe e.V.) in the latest <br />version. <br />Observe applicable safety data sheet! <br />GISCODE: ZP1</p> <p>SCHOMBURG GmbH & Co.
