Thanks to the high <br />deformability of UNIFIX-S3-fast, damaging shear stresses <br />in the covering can be largely compensated out and so <br />it is also particularly well suited to use as bedding mortar <br />for large formats. UNIFIX-S3-fast is primarily used on floor <br />areas. <br />UNIFIX-S3-fast is particularly well suited to use on <br />balconies and terraces, in swimming pool surrounds,</p> <p>on heated constructions, on new, load-bearing, cementbased substrates and for laying tiles and boards with low <br />water absorption. <br />Thanks to the high elasticity, high stresses, such as occur <br />between substrates and coatings in exterior areas or <br />when laying on new, walkable cement-based screeds <br />(approx. 3 days after being put down) and heated <br />screeds, for example, can also be reliably absorbed <br />with UNIFIX-S3-fast. <br />The vapour permeability of UNIFIX-S3-fast guarantee <br />that cement-based substrates that are still moist will dry <br />out properly, even when laying is carried out early. The <br />obligatory heating of the screed before laying ceramic <br />materials can be omitted. <br />As a result of the rapid crystalline binding of the mixing <br />water, the flexible mortar is suitable for a variety of <br />artificial and natural stone. When laying natural stone <br />materials, the product-specific properties of the natural <br />stone, e.g. sensitivity to discolouration and curling effects, <br />must be taken into account. We recommend <br />ASODUR-EK98 or ASODUR-DESIGN for laying stone <br />that contains serpentinite. <br />UNIFIX-S3-fast is a system component on mineral and <br />dispersion-bound SCHOMBURG bonded waterproof <br />systems in the wear classes A, A0, B0 and water influence <br />classes W0-I, W1-I, W2-I, W3-I. <br />Technical data: <br />Combination product comprising: <br /> <br />A component <br /> <br />Powder <br /> <br />component <br />Basis: <br />Aggregate <br /> <br />special binding <br /> <br />agent based <br /> <br />on cement, <br /> <br />additives </p> <p>1/4</p> <p>B component <br />Liquid <br />component <br />liquid polymer</p> <p>13/18</p> <p>Colour: <br />Creamy white <br />White <br />Mixing <br />ratio: <br />3 parts by weight 1 part by weight <br />Packaging: <br />15 kg sack <br />5 kg canister <br />Storage: Dry, 12 months <br />frost-free, 12 months <br />in the original unopened container <br />UNIFIX-S3-fast (combination product) <br />Mixing ratio: <br />15 kg A-comp.

It must have a primarily closed surface <br />condition and exhibit strength typical of its type. Substrate <br />preparation and application per DIN 18157, part 1, and <br />the application specifications of UNIFIX-S3-fast that differ <br />from this, are authoritative when laying tiles. <br />Prime absorbent substrates with ASO-Unigrund. Calcium <br />sulphate screeds must be roughened, vacuumed and <br />primed with ASO-Unigrund - as with all calcium sulphate <br />bound substrates. Heated screeds must be heated in <br />accordance with recognised standards before installation <br />of coverings. Moisture measurement should be carried <br />out with the CM device to assess whether it is ready for <br />laying on. The CM moisture readings may not exceed <br />• CA without floor heating system ≤ 0.5% <br />• CA with floor heating system ≤ 0.3%. <br />Tiles can be laid on cement-based screeds with <br />UNIFIX-S3-fast, as soon as the screed is able to withstand <br />loads. Concrete substrates after 28 days. The CM <br />measurement must be completed in accordance with the <br />current working instructions FBH-AD from the technical <br />information "Interface coordination with heated floor <br />constructions". Surface irregularities in substrates that are <br />ready for laying can be compensated out beforehand <br />with SOLOPLAN-30-PLUS, for example. <br />Application: <br />UNIFIX-S3-fast is a combination product and is shipped <br />in accordance with the mixing ratio. First, add the B <br />component into a clean mixing bucket. Next, add <br />the A component (powder) and continue mixing until <br />a homogeneous bulk density is produced. For lighter <br />working up to 1.35 l of water can be added, depending <br />on the desired slump resistance. After a short maturing <br />time, mix again. Do not mix more UNIFIX-S3-fast than can <br />be used within the pot life. <br />Mixing ratio: <br />15 kg A component (powder): 5 kg B component : <br />depending on the desired consistency, spread up to</p> <p>2/4</p> <p>13/18</p> <p>1.35 l water UNIFIX-S3-fast evenly onto the substrate and <br />comb through with an suitable notched trowel, depending <br />on the board size/material. Lay the surfacing materials <br />within the adhesive open time (finger test). In exterior <br />areas and continuously wet areas, ensure that there <br />are no cavities in the bedding for the tiles and boards. <br />Special notched trowels (e.g. HFV notch, Flowline) have <br />proven useful for this. <br />Notes: <br />•W <br /> hen laying natural stone and synthetic stone, the <br />product-specific properties of the coating materials <br />(tendency for discolouration, curling effects, etc.) and <br />the laying recommendations of the manufacturer must <br />be taken into account. We recommend carrying out <br />a trial laying. <br />• T he relevant guidelines (DIN, ZDB data sheets <br />[German construction industry association]) still insist <br />on a 28-day waiting time for cement-based substrates. <br />Our experience with the elastic thin-bed mortar <br />UNIFIX-S3-fast have shown that damage-free laying is <br />certainly possible on newer substrates. For this reason, <br />we recommend agreeing this special construction <br />method in the contract. <br />•W <br /> ith the combination of newer substrates and the <br />laying of large-format tiles, the tile size should be <br />restricted to max. 60 × 60 cm. A joint width of min. <br />3 mm should be planned. With formats larger than <br />60 × 60 cm, the CM moisture of the screed should also <br />be checked. For cement-based screeds on insulation or <br />separating layers, in this case a CM moisture readings <br />of ≤ 2.0 CM % should be complied with. <br />• P rerequisite for laying tiles on new substrates is <br />compliance with the following criteria: The arrangement <br />of movement joints complies with the relevant guidelines. <br />Use notched trowel of min. 10 mm in order to be able to <br />accommodate minor deformations of the substrate. <br />Heating screed constructions must generally be <br />completed from the 21st day after laying the screed <br />in accordance with the relevant guidelines (ZDB data</p> <p>sheet). The earliest possible time for starting laying is <br />after the screed is walkable, generally after minimum <br />3 to 8 days. The screed must have reached minimum <br />70% of its final strength (in normal cases, after 7 days). <br />Complete grouting with hydraulically hardening grout, <br />e.g. ASO-Flexfuge or HF05-Brillantfuge. <br />• When working on new, cement-based substrates <br />(screed, heated screed), the reduced full service <br />conditions of the screed construction must be taken into <br />account. Do not place heavy tools, surfacing materials, <br />etc., on the screed, in particular in areas at risk of <br />breakage – ensure load spreading measures. <br />• To avoid curling effects due to water absorption, we <br />recommend using ASODUR-EK98 when working with <br />agglomerates / synthetic stone. <br />• Direct solar radiation and draughts can result in <br />a skin forming prematurely or to the open time being <br />shortened. <br />• UNIFIX-S3-fast is a hydraulically hardening mortar with <br />a dispersion component rate that can take several days <br />before being fully hardened in unfavourable climatic <br />conditions or when exposed to weather influences and <br />so it must be protected from exposure to water and <br />frost in the meantime. <br />• Protect surfaces that are not to be treated from the <br />effects of UNIFIX-S3-fast. <br />• Avoid contact with eyes and skin. <br />• Prime calcium sulphate bound substrates with <br />ASO-Unigrund-GE or ASO-Unigrund-K (mix ratio 1:3 <br />with water)! When laying tiles on calcium sulphate <br />bound substrates, UNIFIX-AEK is useful to avoid <br />ettringite formation with residual moistures of 1.0 % with <br />heated or 1.5 % per CM with unheated constructions! <br />• Do not add water or new mortar to existing thin-bed <br />mortar already in the binding process in order to <br />make it workable again as this would involve a risk of <br />inadequate strength development! <br />• Direct contact between cement tile mortar and <br />magnesite screeds leads to the destruction of the <br />magnesite screeds through a chemical reaction known <br />as "magnesite pouring". Moisture pressure from</p> <p>3/4</p> <p>13/18</p> <p>the rear of the substrate must be prevented through <br />appropriate measures. The magnesite substrate should <br />be mechanically roughened and primed with the epoxy <br />resin ASODUR-V360W plus max. 5 % water (approx. <br />250 g/m2). After a waiting time of approx. 12–24 <br />hours at +20 °C, the second coat of <br />ASODUR-V360W should be applied (approx. <br />300–350 g/m2). While the second coat is still fresh, <br />apply plenty of quartz sand with 0.5–1.0 mm grain <br />size. Installation of coverings may be completed after a <br />further waiting time of approx.12-16 hours. <br />• The current relevant regulations are to be observed! <br />So, for example: <br />DIN 18157 <br />DIN 18352 <br />DIN 18560 <br />DIN 18202 <br />EN 13813 <br />DIN 1055 <br />The BEB data sheets, issued by the Bundesverband <br />Estrich und Belag e.V.
