The <br />high deformability of UNIFIX-S3 can largely compensate <br />for the damaging shear stresses in the tiled finish and <br />is therefore also especially suitable for the installation <br />of large format tiles. UNIFIX-S3 is used primarily in <br />floor areas. UNIFIX-S3 is especially suitable for use <br />on balconies and terraces, in swimming pools and <br />containers, on heated constructions, on ‘green’ heavier</p> <p>duty cement-based substrates and for the installation of <br />tiles with lower water absorption. <br />Due to its high elasticity high stresses are also reliably <br />accommodated with UNIFIX-S3 (deflection in accordance <br />with DIN EN 12002 > 30 mm without breakage of the <br />test piece), such as those that arise e.g. between substrate <br />and tiled finish in exterior areas or when installing on <br />‘green’, trafficked cement-based screeds (approx. 3 days <br />after laying) and heated screeds. <br />The vapour permeability of UNIFIX-S3 guarantees that <br />cement-based substrates, which are still damp, will dry <br />out even when installing tiles early. The mandatory <br />commissioning of heated screeds before the installation of <br />ceramic materials can be omitted. <br />When installing natural stone materials make allowances <br />for the specific product properties of the natural stone, <br />sensitivity to discolouration and curling. Dependent on <br />the natural stone and where it is to be installed, we <br />recommend the CRISTALLIT series or UNIFIX-S3-Fast as <br />the bedding mortar on balconies and terraces. <br />UNIFIX-S3 is a system component of the bonded tiled <br />waterproof system AQUAFIN-2K/M + UNIFIX-S3. <br />UNIFIX-S3 is suitable for use on mineral-based and <br />dispersion-based SCHOMBURG bonded waterproof <br />systems. <br />Technical Data: <br />Powder component Liquid component <br />Basis:</p> <p>aggregate, cement, liquid polymer <br />additives <br />Colour: <br />grey <br />white <br />Mixing ratio: 3 parts by weight <br />1 part by weight <br />Packaging: 15 kg bag <br />5 kg bucket <br />Storage: <br />dry, 12 months <br />frost free, 12 months <br />in the original unopened container</p> <p>1/4</p> <p>35/17</p> <p>UNIFIX-S3 (combined product) <br />Mixing ratio: <br />15 kg powder component : 5 kg <br />liquid component : up to 1.6 litres <br />water <br />Application/ <br />substrate temp.: <br />+ 5 °C to + 25 °C <br />Pot life *): <br />approx. 2 hours <br />Open time *): <br />approx. 30 minutes <br />Grout after *): <br />2 days at the earliest dependent on <br />the porosity of the substrate <br />Foot traffic after *): 2 days at the earliest dependent on <br />the porosity of the substrate <br />Fully serviceable <br />after *): <br />14 days at the earliest dependent <br />on the porosity of the substrate <br />Cleaning: <br />with water immediately after use <br />Deformation: <br />30.9 mm to DIN 12002 – without <br />breakage of the test piece <br />Testing: <br />• DIN EN 12004 <br />• DIN EN 12002 <br />Consumption: <br />approx. 2.80 kg/m2 <br />with a 6 mm notched trowel <br />approx. 3.70 kg/m2 <br />with an 8 mm notched trowel <br />approx. 4.70 kg/m2 <br />with a 10 mm notched trowel <br />*) These values relate to +20° C and 65% relative humidity, higher</p> <p>temperatures shorten and lower temperatures lengthen these given times.</p> <p>Substrate preparation: <br />The substrate must be dry, load bearing, adequately flat, <br />free from penetrating cracks and free from separating <br />substances such as e.g. oil, paint, laitance layers and <br />loose constituents. It must possess a largely closed surface <br />with a surface condition and strength in accordance with</p> <p>its type. DIN 18157, part 1 and the divergent application <br />specifications of UNIFIX-S3 prevail when installing tiles <br />regarding the substrate, substrate preparation and <br />product application. Prime porous substrates with <br />ASO-Unigrund. Calcium sulphate screeds must be <br />mechanically abraded, vacuumed and as with all <br />substrates based on calcium sulphate binders, primed with <br />ASO-Unigrund-K diluted 1:3 with water. Heated screeds <br />must be commissioned in accordance with recognised <br />technical regulations before installing floor finishes. To <br />determine a substrate’s readiness to receive finishes <br />carry out a moisture test with a carbide hygrometer (CM <br />device). The CM moisture readings may not exceed: <br />• CA without underfloor heating ≤ 0.5% <br />• CA with underfloor heating ≤ 0.3% <br />Tiles can be installed with UNIFIX-S3 on cement-based <br />screeds as soon as they will take foot traffic, concrete <br />substrates after 28 days, independent of the moisture <br />content. <br />The CM readings are to be carried out in accordance <br />with current FBH-AD work instructions taken from the <br />technical information for the “coordination of cut out points <br />in heated floor constructions”. <br />Unevenness in the substrate that is ready to receive tiles <br />can be levelled out beforehand with SOLOPLAN-30-PLUS. <br />Product preparation: <br />UNIFIX-S3 is a combination product and is supplied <br />at a predetermined mix ratio. Firstly add the liquid <br />component B to a clean mixing bucket. Then add the <br />powder component whilst stirring and continue to mix <br />until a homogenous consistency is achieved. For ease of <br />application up to a maximum of 8% (approx. 1.6 litres) of <br />water can be subsequently added. After a short standing <br />time, stir the thin bed adhesive once again. Do not mix <br />more UNIFIX-S3 than can be used within the pot life of <br />approx. 2 hours.</p> <p>2/4</p> <p>35/17</p> <p>Mixing ratio: <br />15 kg UNIFIX-S3 : 5 kg UNIFLEX-B : dependent on <br />desired consistency up to 1.6 litres water <br />Trowel UNIFIX-S3 onto the surface of the substrate and <br />comb through with a notched trowel suitable for the tile <br />size/material. Install tiles within the open time (finger <br />test). In exterior areas and continuously wet areas ensure <br />that as far as possible a void free bedding of the tiles is <br />achieved. Special trowels (e.g. HFV notch, Flowline) have <br />proved successful for this purpose. <br />A waterproofing function is achieved when UNIFIX-S3 <br />is trowelled out at a uniform 2 mm thickness. <br />Apply ASO-Joint-Tape-2000/preformed pieces at wall/ <br />floor junctions or over movement joints, free from voids <br />or folds, with UNIFIX-S3. Joints are to be carried out by <br />overlapping a minimum 5 to 10 cm. Once the membrane <br />has hardened then the tiles can be installed using the <br />previously mentioned application technique. <br />Advice: <br />• The relevant regulations (DIN, ZDB data sheets) still <br />insist on keeping to a 28 day waiting time for cementbased substrates to receive finishes. Longstanding <br />experience with the elastic thin bed adhesive <br />UNIFIX-S3 has shown that it is possible to safely <br />achieve a damage free installation even on ‘green’ <br />substrates. We agree to recommend this special <br />construction method by contract. <br />• When there is a combination of an uncured <br />substrate and the installation of large format tiles, the <br />tile size is to be restricted to a surface area of 0.36 m2, <br />60 × 60 cm format. Plan for a joint width of at least <br />3 mm. With larger format tiles, additionally test the <br />moisture content of the screed by the carbide method. <br />For cement-based screeds on insulation or a separating <br />layer, keep to a carbide method moisture content of <br />≤ 2.0 CM%. <br />• It is a prerequisite that the following criteria are <br />followed: <br />The positioning of movement joints must conform to</p> <p>relevant regulations. Use a minimum trowel notch of <br />8 mm in order to be able to absorb minimal <br />deformation within the substrate. Undertake the <br />commissioning (heating up) of screeds from the 21st <br />day after installation in conformance with relevant <br />regulations (ZDB data sheet). The tile installation begins <br />as early as possible depending on the ability to traffic <br />the screed; as a rule after a minimum of 3 to 8 days. <br />The screed must have achieved at least 70% of its final <br />strength (normally after 7 days). Carry out grouting with <br />hydraulically setting grouts e.g. ASO-Flexfuge or <br />HF05-Brillantfuge. <br />• When working on uncured cement-based substrates <br />(screeds, heated screeds), take note of the reduced <br />load carrying capacity of the screed construction. <br />Do not store heavy tools, floor finishing materials etc. <br />on the screed especially in areas at risk of breakage – <br />use load spreading measures. <br />• When installing natural and synthetic stone the specific <br />properties of these products (tendency to discolour, risk <br />of curling etc.) and the installation recommendations of <br />the manufacturer are to be observed. In cases of doubt <br />carry out a fixing trial. <br />• To avoid curling effects due to water absorption we <br />recommend the use of ASODUR-EK98 or <br />ASODUR Design with agglomerate/synthetic stone. <br />• Direct sunlight and draughts can lead to the early <br />formation of a skin or to a shortened open time. <br />• UNIFIX-S3 is a hydraulically setting adhesive with a <br />dispersion component that until fully hardened is to be <br />protected from water and frost penetration, which can <br />take a few days under inclement weather influences/ <br />climatic conditions. <br />• The filling of pools, containers etc. may only be <br />implemented after a minimum of 28 days. <br />• Areas not being treated are to be protected from the <br />effects of UNIFIX-S3. <br />• Avoid contact with the eyes and skin. <br />• Prime calcium sulphate based substrates with <br />ASO-Unigrund-GE or ASO-Unigrund-K (mix ratio 1:3 <br />with water). To avoid the formation of ettringite with</p> <p>3/4</p> <p>35/17</p> <p>calcium sulphate based substrates UNIFIX-AEK is suited <br />for the installation on these substrates up to residual <br />moisture values of 1.0% with heated and 1.5% with <br />unheated constructions, measured with a carbide <br />hygrometer. <br />• Do not re-life adhesive that has already started to stiffen <br />by adding more water or fresh adhesive as there is a <br />risk of inadequate strength development. <br />• The direct contact between cement-based adhesives <br />and magnesium screeds leads to the destruction of the <br />magnesium screed via a chemical reaction. <br />Moisture pressure from the rear of the substrate must <br />be eliminated with appropriate measures. <br />Mechanically abrade the magnesium substrate and <br />prime with the epoxy resin ASODUR-V360W with <br />the addition of max. 5% water as necessary (approx. <br />250 g/m2). Wait for approx. 12-24 hours at +20 °C <br />then apply a second coat of ASODUR-V360W <br />(approx.300-350 g/m2). Broadcast quartz sand of <br />particle size 0.5-1.0 mm to excess into the wet second <br />coat. After waiting for a further 12-16 hours, installation <br />may be commenced. <br />• In continuously wet areas (swimming pools, containers <br />etc.) ensure that, as far as possible, the tiles are <br />bedded free from voids. For this purpose special <br />trowels (e.g. HFV notch, Flowline) have proved <br />successful. The spreading of adhesive on the rear of <br />tiles can be omitted with suitable installation techniques, <br />in so far as the Floating-Buttering method has not <br />been explicitly specified from a planning aspect. It <br />is recommended to continually monitor the results of <br />workmanship.</p> <p>• Observe the relevant current regulations.
