Thanks to the high <br />deformability of UNIFIX-S3, damaging shear stresses in the <br />covering can be largely compensated for. UNIFIX-S3 may <br />be adjusted with the addition of water for non-slump or <br />flowing bed consistency.</p> <p>Thanks to its high elasticity, UNIFIX-S3 reliably absorbs <br />high stresses, for example those that occur between <br />substrates and surface in exterior areas or when laying <br />on new, walkable cement-based screeds (approx. 3 days <br />after being put down) and heated screeds. <br />The vapour permeability of UNIFIX-S3 guarantee that <br />cement-based substrates that are still moist will dry out <br />properly, even when laying is carried out early. The <br />obligatory heating of the screed before laying ceramic <br />materials can be omitted. <br />When laying natural stone materials, the productspecific properties of the natural stone, and sensitivity <br />to discolouration and curling effects must be taken into <br />account. <br />UNIFIX-S3 is a system component of the bonded tiled <br />waterproof system AQUAFIN-TBS. UNIFIX-S3-fast is <br />suitable on mineral and dispersion-bound SCHOMBURG <br />bonded waterproof systems in the wear classes A, B, A0, <br />and B0 and water influence classes W0-I to W3-I, W1-B, <br />and W2-B. <br />UNIFIX-S3 is suitable for use in interior spaces according <br />to the AgBB evaluation diagram (committee for health <br />hazard evaluation of building products, French VOC <br />Directive, and Belgian Royal Decree C-2014/24239. <br />Very low emissions in accordance with GEV-EMICODE, <br />which normally results in positive evaluations within the <br />scope of building certification systems in accordance with <br />DGNB, LEED, BREEAM, HQE. <br />Maximum quality level 4, line 8 in accordance with <br />DGNB criteria “ENV 1.2 Risks to the local environment”.</p> <p>UNIFIX-S3 is particularly well suited to use on balconies <br />and terraces, in swimming pools and containers, on <br />heated constructions, on new, load-bearing, cement-based <br />substrates, and for laying tiles and boards with low water <br />absorption.</p> <p>1/4</p> <p>22/18</p> <p>Technical data: <br /> <br />A component <br />B component <br /> <br />Powder component Liquid component <br /> <br />UNFIX-S3 UNIFLEX-F <br />Basis: aggregate, <br />liquid polymer <br />cement, additives <br />Colour: grey white <br />Mixing <br />ratio: <br />3 parts by weight 1 part by weight <br />Packaging: <br />15 kg sack + 5 kg canister <br /> <br />25 kg sack + 8.33 kg canister <br />Storage dry, <br />frost-free, <br />12 months in the original unopened <br />container <br /> <br />UNIFIX-S3 (combined product) <br />Mixing ratio: <br />Non-slump 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 that differ from <br />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-K. as with all calcium sulphate <br />bound substrates, and diluted at a ratio of 1:3 water. <br />Heated screeds must be heated in accordance with <br />recognised standards before installation of coverings. <br />Moisture measurement should be carried out with the CM</p> <p>2/4</p> <p>22/18</p> <p>device to assess whether it is ready for laying on. <br />The CM moisture readings may not exceed <br />• CA without floor heating system ≤ 0.5% <br />• CA with floor heating system ≤ 0.3%.</p> <p>A component <br />In case of non-slump setting, grouting is normally possible <br />on the following day. In case of flow bed mortar, grouting <br />may normally begin after two days.</p> <p>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, independent <br />of moisture content. The CM measurement must be <br />completed in accordance with the current working <br />instructions FBH-AD from the technical information <br />"Interface coordination with heated floor constructions". <br />Surface irregularities in substrates that are ready for <br />laying can be compensated out beforehand with e.g. <br />SOLOPLAN-30-PLUS.</p> <p>Spread UNIFIX-S3 evenly across the substrate and <br />comb through with a suitable notched trowel to suit the <br />board size/material. Lay the surfacing materials within <br />the adhesive open time (finger test). In exterior areas and <br />continuously wet areas, ensure that there are no cavities <br />in the bedding for the tiles and boards. Special notched <br />trowels (e.g. HFV notch, Flowline) have proven useful for <br />this.</p> <p>Application: <br />UNIFIX-S3 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 the <br />A component (powder) and continue mixing until a <br />homogeneous bulk density is produced. For easier <br />application, up to max. 9% water in relation to the A <br />component may be added. After short maturing time of <br />approx. 3 minutes, the mixed thin-bed mortar must be <br />stirred again. Do not mix more UNIFIX-S3 than can be <br />used within the pot life of approx. 60 minutes. <br />Mix ratio, non-slump and very deformable (corresponds <br />with class C2 TE S2, deflection in accordance > 5 mm): <br />5 kg B component : up to 0.25 l water : 15 kg <br />A component <br />8.33 kg B component : up to 0.40 l water : 15 kg <br />A component <br />Mix ratio, flow bed and very deformable (corresponds <br />with class C2 E S2, deflection in accordance > 5 mm): <br />5 kg B component : up to 1.35 l water : 15 kg <br />A component <br />8.33 kg B component : up to 2.25 l water : 25 kg</p> <p>Important instructions: <br />• The 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 />Many years of experience with elastic thin-bed mortar <br />UNIFIX-S3 have shown that non-destructive placement is <br />also certainly possible on newer substrates. <br />Prerequisite 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 />Maintain an adhesive bed thickness of min. 3 mm <br />(depending on the placement angle, approx. 8 mm <br />trowel) to compensate for any slight deformations in the <br />substrate. Heating screed constructions must generally <br />be completed from the 21st day after laying the screed <br />in accordance with the relevant guidelines (ZDB data <br />sheet). Placement begins as soon as possible, and <br />normally minimum 3 to 8 days after the screed is able to <br />be walked on. 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</p> <p>3/4</p> <p>22/18</p> <p>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 />• When 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 completing <br />a trial adhesion. <br />• To avoid curling effects due to water absorption, we <br />recommend using ASODUR-EK98/ASODUR-DESIGN <br />when working with agglomerates/synthetic stone. <br />• Direct solar radiation and draughts can result in a <br />skin forming prematurely or to the open time being <br />shortened. <br />• UNIFIX-S3 is a hydraulically hardening mortar with <br />dispersion component rate that can take a few 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 frost <br />in the meantime. <br />• Pools, containers, etc. may only be filled after 28 days <br />at the earliest. <br />• Protect surfaces that are not to be treated against the <br />effects of UNIFIX-S3. <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</p> <p>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 <br />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 to <br />24 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 />• In continuously underwater areas (swimming pools, <br />containers, etc.) ensure that there are no cavities in <br />the bedding for the tiles and boards. Special notched <br />trowels (e.g. HFV notch, Flowline) have proven useful <br />for this. Placement of the bedding mortar on the rear of <br />the board may be omitted if the bedding technique is <br />suitable, provided the floating-buttering method is not <br />prescribed exclusively from a planning perspective. <br />We recommend checking the work results continuously. <br />• Protect surfaces that are not to be treated against the <br />effects of UNIFIX-S3! <br />Please observe valid EU safety data sheets! <br />GISCODE: ZP1</p> <p>Information about the emission level of volatile compounds in indoor <br />air, which pose a health risk by inhalation, on a scale from class A+ <br />(very low emissions) to C (high emissions).</p> <p>The rights of the buyer with regard to the quality of our materials are based on our terms and conditions of sale and delivery.
