MONOFLEX-XL is suited for the <br />assured installation on all substrates conforming to <br />DIN 18157, part 1 e.g. concrete, aerated concrete, <br />render/plaster, cement-based and calcium sulphate</p> <p>based screeds/heated screeds, masonry work, moisture <br />resistant plasterboard etc. as well as on old well bonded <br />tiled finishes. It is additionally suitable as a bonding <br />material for lightweight construction boards, e.g. extruded <br />polystyrene (tilebacker boards) and for tiling onto mineralbased and dispersion-based SCHOMBURG waterproof <br />membranes e.g. in wet duty areas, communal showers, <br />swimming pool surrounds etc. <br />MONOFLEX-XL is suitable for use in interior rooms <br />in accordance with the AgBB evaluation scheme <br />(Committee for Health-related Evaluation of Building <br />Products), the French VOC by-law and the Belgian <br />Royal Decree C-2014/24239. Very low emissions in <br />accordance with GEV-EMICODE, which as a rule leads <br />to positive evaluations within the framework of building <br />certification systems according to DGNB, LEED, BREEAM <br />and HQE. Highest quality level 4, row 8 in accordance <br />with the DGNB criterion “ENV 1.2 Local environmental <br />impact“. <br />Technical Data: <br />Basis: sand, cement, additives <br />(polymer modified) <br />Colour: <br />cement grey <br />Application temperature: +5° C to +25° C <br />Pot life *): <br />approx. 2 hrs <br />*) <br />> 30 mins <br />Open time : <br />Grout *): after approx. 12 hrs **) <br />Foot traffic *): <br />after approx. 12 hrs **) <br />Full service conditions *): after approx. 7 days <br />Testing: <br />· DIN EN12004 and <br />DIN EN 12002, <br />KIWA Bautest DD <br />4149/01/2011 <br /> <br />· v ery low emission in <br />accordance with GEV <br />EMICODE, AgBB scheme and <br />French VOC by-law <br />Cleaning: clean with water immediately <br />after use</p> <p>1/4</p> <p>35/17</p> <p>Consumption: approx. 1.6 kg/m2 <br />with a 6 mm notched trowel <br />approx. 2.1 kg/m2 <br />with an 8 mm notched trowel <br />approx. 2.6 kg/m2 <br />with a 10 mm notched trowel <br />Packaging: <br />25 kg bag <br />Storage: dry, 12 months in the original <br />unopened packaging. Use opened <br />packaging promptly <br />*) These values relate to +23° C and 50% relative humidity. <br />**) At a gauging water addition of 9.5 l/25 kg MONOFLEX-XL.</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 oil, paint, laitance and loose parts. <br />They must have a largely closed surface with a surface <br />strength and condition commensurate with their type. <br />When installing tiles, the substrate, substrate preparation <br />and product application must conform to DIN 18157, <br />part 1. Prime porous substrates with ASO-Unigrund. <br />Calcium sulphate screeds must be abraded, vacuumed <br />and as with all calcium sulphate based substrates primed <br />with ASO-Unigrund. If large format tiles are to be installed <br />on calcium sulphate based screeds, we recommend <br />priming with ASODUR-V360W due to its greater barrier <br />effect. Heated screeds must be commissioned prior to the <br />installation of tiled flooring in accordance with recognized <br />technical regulations. The readiness of a substrate to <br />receive tiled finishes is to be determined through moisture <br />measurements with a carbide hygrometer (CM device). <br />The CM moisture content may not exceed: <br />• Cement-based screeds (CT) 2.0 CM% for unbonded <br />or floating screeds <br />• Calcium sulphate based screeds (CA) without <br />underfloor heating 0.5 CM% <br />• Calcium sulphate based screeds (CA) with underfloor <br />heating 0.3 CM%</p> <p>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 and application: <br />Mix MONOFLEX-XL with clean water in a clean mixing <br />bucket until homogenous. <br />Mix ratio: <br />9.25–11.00 litres water : 25 kg MONOFLEX-XL. <br />Allow to stand for approx. 3 minutes then remix. Do not <br />prepare more adhesive than can be used within the pot <br />life. Spread the mixed adhesive over the substrate surface <br />and comb through with a notched trowel suitable for the <br />tile format. Install tiles within the <br />adhesive open time. <br />When installing large format tiles greater than <br />60 x 60 cm, we recommend that MONOFLEX-XL is <br />modified with UNIFLEX-B. Modifying with UNIFLEX-B <br />elastifier increases the deformability and adhesion <br />strength of MONOFLEX-XL. Dependent on the <br />modification, deformability class S2 can be achieved, <br />which is particularly recommended for tiles larger than <br />60 x 60 cm. This considerably compensates for shear <br />stresses, which can lead to delamination in unfavourable <br />exterior conditions. <br />UNIFLEX-B is mixed with water for improved application <br />and then mixed with MONOFLEX-XL until homogenous. <br />Mixing ratio: highly deformable (relates to class C2 S2, <br />deformation > 5 mm): <br />4.17 kg UNIFLEX-B : approx. 5.0 litres water : 25 kg <br />MONOFLEX-XL</p> <p>2/4</p> <p>35/17</p> <p>Important advice: <br />• When installing tiles in heavy duty areas in exterior <br />locations (balconies and terraces) the highly elastic <br />bonded waterproof membrane system AQUAFIN-2K/M <br />and UNIFIX-S3 or UNIFIX-2K should be used. <br />• When installing natural and synthetic stone tiles pay <br />particular attention to the specific product properties of <br />the material to be fixed (tendency to discolour, risk of <br />curling etc) and follow the manufacturer’s installation <br />recommendations. We recommend that <br />a trial area is carried out. <br />• To avoid curling effects due to water absorption <br />when installing agglomerate/synthetic stone tiles <br />we recommend the use of ASODUR-EK98 or <br />ASODUR-Design. <br />• When installing large format tiles greater than <br />50 x 50 cm, in order to improve the adhesion, a <br />scratch coat should be applied to the rear of the tile <br />or they should be fixed in the buttering-floating method. <br />• Prime calcium sulphate based substrates with <br />ASO-Unigrund-S (mix ratio 1:1 with water). <br />• To avoid the formation of ettringite with calcium <br />sulphate based substrates, UNIFIX-AEK is a suitable <br />adhesive for installing tiles to these substrates up <br />to residual moisture levels of 1.0% for heated and <br />1.5% for unheated constructions (CM% - carbide <br />hygrometer). <br />• Do not attempt to re-life thin-bed adhesive that has <br />already stiffened by adding water or fresh mortar, there <br />is a risk of inadequate strength development. <br />• In continuously immersed areas (swimming pools, <br />containers etc.) we recommend the use of the system <br />based thin bed adhesive UNIFIX-2K/6 onto the <br />SCHOMBURG waterproof membrane appropriate for <br />the particular application. <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</p> <p>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. <br />• MONOFLEX-XL is a hydraulic hardening mortar <br />that needs to be protected against water and frost <br />penetration until fully cured, which may take a few days <br />in bad weather conditions. <br />• Protect areas not be treated with MONOFLEX-XL. <br />• Heed the relevant current regulations.
