The substrate surface must have a largely closed texture <br />and its condition must be appropriate for its type. For tiling, the substrate, its <br />preparation and product application must conform to DIN 18157, <br />part 1. Prime absorbent substrates with ASO®-Unigrund. <br />Heated floors are to b e heated prior to installing tiles. The readiness of a <br />substrate to receive finishes is to be determined by the carbide (CM) <br />method and may not fall below the following values: <br />•CT ≤ 2.0% (when installing large format tiles 1.5%) <br />•CA/CFA unheated ≤ 0.5%, heated ≤ 0.3%</p> <p>io n</p> <p>* compared with conventional cement-based <br />adhesives without lightweight aggregates</p> <p>Product preparation: <br />Mix LIGHTFLEX with clean water in a clean mixing bucket until <br />homogenous. Mixing ratio: <br />• as a thin-bed adhesive: 7.5 – 8.1 litres water: 15 kg LIGHTFLEX® <br />• as a smoothing mortar: 7.4 – 7.9 litres water: 15 kg LIGHTFLEX® <br />• as a mesium-bed adhesive: 7.4 – 7.9 litres water: 15 kg LIGHTFLEX® <br />• as a flow-bed adhesive: 10.2 – 10.8 litres water: 15 kg LIGHTFLEX® <br />Allow to stand for 4 minutes, then mix thoroughly through once again. <br />When using as a flow-bed adhesive firstly mix LIGHTFLEX® with approx. 8 <br />litres of water and subsequently mix in the remaining water until a pourable <br />consistency is achieved. Do not mix more material than can be used within <br />the pot life. Spread the mixed adhesive over the substrate and dependent <br />on the tile format comb through with the appropriate notched trowel. Fix <br />the finishing material within the adhesive open time. When installing large <br />format tiles, we recommend that LIGHTFLEX® is modified with UNIFLEX®-B. <br />Modification with this elastifier improves the deformability and tensile <br />adhesion of LIGHTFLEX®. Dependent on the level of modification, S2 <br />deformation class can be achieved which is particularly recommended for <br />larger tiles. This considerably compensates for shear stresses, which can <br />lead to delamination in unfavourable exterior conditions. UNIFLEX®-B is <br />mixed with water for improved application and then mixed with <br />LIGHTFLEX® until homogenous.</p> <p>l o w e m iss</p> <p>11 Applying a contact layer with large <br />format tiles</p>
