Higher <br />temperatures shorten, lower temperatures lengthen the declared times.</p> <p>1/3</p> <p>26/17</p> <p>Substrate preparation: <br />MONOFLEX-FB is suitable for a secure bond to all floor <br />substrates e.g. concrete, cement-based and calcium <br />sulphate based screeds / heated screeds. The substrate <br />must have a virtually closed surface and a surface <br />condition and strength appropriate for its type. The <br />substrate must be dry, clean, load bearing, and be free <br />from separating substances and penetrating cracks. <br />Remove coatings, paint, oil, laitance and loose parts. <br />Abrade smooth concrete surfaces and prime porous <br />substrates with ASO-Unigrund before tiling. Anhydrite <br />screeds must be mechanically abraded, vacuumed and <br />as with all calcium sulphate bound substrates thoroughly <br />primed with ASO-Unigrund. With tile formats, which have <br />edges longer than 60 x 60 cm, we recommend treating <br />moisture sensitive substrates, such as e.g. calcium sulphate <br />screeds, with a reaction resin primer. <br />When installing tiles, the substrate, substrate preparation <br />and product application must conform to DIN 18157, <br />part 1. <br />The readiness of a substrate to receive tiled finishes is <br />to be determined through moisture measurements with <br />a carbide hygrometer (CM device). The CM moisture <br />content may not exceed: <br />• CT ≤ 2.0 CM% for screeds on insulation or <br />separating layers <br />• CA without underfloor heating ≤ 0.5 CM% <br />• CA with underfloor heating ≤ 0.3 CM %. <br />The CM measurements are to be carried out to the <br />current FBH-AD work instructions from the technical <br />information “Coordination of cut out points with heated <br />floor constructions.” <br />Product preparation: <br />Mix MONOFLEX-FB with clean water in a clean mixing <br />bucket until homogenous. <br />Mixing ratio: <br />6 to 6.4 litres water : 25 kg MONOFLEX-FB</p> <p>On external horizontal surfaces e.g. balconies and <br />terraces MONOFLEX-FB can be modified with <br />UNIFLEX-B. For improved workability with <br />MONOFLEX-FB and UNIFLEX-B add water after mixing <br />the two materials. <br />Mixing ratio: <br />8.33 kg UNIFLEX-B : 25 kg MONOFLEX-FB : 2.5 l water. <br />The addition of UNIFLEX-B lengthens the adhesive open <br />time and pot life somewhat. The deformability to <br />DIN EN 12002 is considerably increased. <br />After allowing to stand for 3 minutes, remix the adhesive. <br />Do not prepare more adhesive than can be used within <br />the pot life. <br />Spread the MONOFLEX-FB on to the substrate and <br />comb through with a suitable notched trowel dependent <br />on tile format – special trowels have been proven (e.g. <br />HFV notches, flowline). Lay finishing materials within the <br />adhesive open time (finger test approx. 30 minutes). <br />Always clean the mixing bucket as setting <br />MONOFLEX-FB acts as an accelerator. Do not mix with <br />other cement-based adhesives. <br />Important advice: <br />• When installing large format tiles in heavy duty areas <br />we recommend that they are vibrated e.g. with a <br />vibration device. Due to its thixotropic properties <br />the MONOFLEX-FB is encouraged to flow through <br />vibration. Voids in the adhesive bed are closed. <br />• To assist in the best possible void free bedding of tiles <br />we recommend that the adhesive bed is combed in <br />one direction so that the air under the tiles can escape <br />via the vent spaces (free space between the ribs). <br />• When installing suitable natural stone observe the <br />specific properties of the material (tendency to <br />discolour, risk of curling etc.) and the installation <br />recommendations of the stone/tile producer. In cases <br />of doubt carry out a trial area.</p> <p>2/3</p> <p>26/17</p> <p>• Perimeter, bay and movement joints are to be reflected <br />through and sealed with a suitable material e.g. edging <br />strip RD-SK50. <br />• To avoid curling effects due to water absorption <br />we recommend the use of ASODUR-EK98 with <br />agglomerate/synthetic stone. <br />• Please heed the current ZDB information sheets <br />distributed by the German tile association, especially <br />when fixing to calcium sulphate based substrates and <br />heated constructions. <br />• Prime calcium sulphate based substrates with <br />ASO-Unigrund-GE or ASO-Unigrund-K (mixing ratio 1:3 <br />with water). In order to avoid the formation of ettringite <br />with calcium sulphate based substrates UNIFIX-AEK <br />is suited for the installation onto these substrates up to <br />residual moisture contents of 1.0% on heated screeds <br />or 1.5% with unheated constructions, measured with a <br />carbide hygrometer. <br />• Do not add more water or fresh mortar to a thin bed <br />adhesive that has started to set in order to re-life it. <br />There is a risk of inadequate strength development. <br />• Direct contact between cement-based tile mortars <br />and magnesite screeds leads to the destruction of <br />the magnesite screed through a chemical reaction. <br />Moisture penetration from the rear must be eliminated <br />with appropriate measures. Mechanically roughen <br />the magnesite screed and prime with the epoxy <br />resin ASODUR-V360W (approx. 250 g/m2) with a <br />maximum of 5% water as necessary. After waiting from <br />12 to 24 hours at +20° C, apply a second coat of <br />ASODUR-V360W (approx. 300 – 350 g/m2). Blind <br />the fresh second coat with 0.5-1.0 mm quartz sand. <br />After waiting for a further 12-16 hours continue with the <br />tile installation.</p> <p>• For waterproofing external surfaces (balconies <br />and terraces) use the elastic waterproofing systems <br />AQUAFIN-2K, AQUAFIN-2K/M or AQUAFIN-RS300. <br />• MONOFLEX-FB is a hydraulically setting adhesive <br />and until fully cured, which may take a few days in <br />unfavourable conditions, protect against water and <br />frost. <br />• Protect areas not be treated with MONOFLEX-FB. <br />• Heed the relevant current regulations. <br />E.g. <br />DIN 18157 <br />DIN 18352 <br />DIN 18560 <br />DIN 18202 <br />EN 13813 <br />DIN 1055 <br />The BEB information sheets, distributed by the <br />Bundesverband Estrich und Belag e.V. <br />The technical information “coordination of cut out points <br />in heated floor constructions”. <br />The ZDB information sheets, distributed by the <br />professional association of the German tile industry: <br /> [*1] „ Bonded waterproof membranes” <br /> [*2] „ Finishes on calcium sulphate screeds” <br /> [*3] „ Movement joints in wall and floor tile finishes” <br /> [*4] „ Ceramic floor finishes in heavy duty areas“ <br /> [*5] „Ceramic</p> <p>tiles and slabs, natural and concrete <br />stone/slabs on cement-based floor constructions <br />with insulation“ <br /> [*6] „Exterior locations“ <br /> [*7] „Swimming pool construction“ <br />Please observe a valid EU safety data sheet. <br />GISCODE: ZP1</p> <p>This technical data sheet does not consider local building codes or legal requirements.
