low, the water is bound in a crystalline form so that a noticeably quicker strength development can be detected in comparison with conventional rapid setting adhesives. SOLOFLEX-FAST is suitable for the secure fixing of tiles to flat, sound substrates and for tiling onto mineral based and dispersion based SCHOMBURG waterproof membranes, in moderate wet duty areas. On horizontal external areas such as e.g. balconies and terraces, modify 25 kg of SOLOFLEX-FAST with 8.33 kg of UNIFLEX-B.

Substrate preparation: SOLOFLEX-FAST is suitable for the secure installation of tiles to dimensionally stable substrates conforming to DIN 18 157 part 1 e.g. concrete, aerated concrete, render / plaster, cement-based and calcium sulfate based screeds, masonry work etc. The substrate must be dry, sound, adequately flat, free from penetrating cracks and free from separating substances such as e.g. oil, paint, laitance and loose areas. It must have a surface condition and strength consistent with its type. When installing tiles, substrate preparation must be carried out to DIN 18 157 part 1. Prime porous substrates with ASO-Unigrund. Calcium sulfate based screeds must be abraded, vacuumed and as with all calcium sulfate based substrates, thoroughly primed with ASO-Unigrund-GE. If large format tiles are to be installed, we recommend that priming is carried out using ASODUR-V360W due its greater barrier forming capacity. Heated screeds must be commissioned in line with recognized technical regulations before tiling. To ascertain a surface’s readiness to receive tiles, carry out moisture measurements with a carbide hygrometer (CM device). The CM moisture content may not exceed: • Cement-based screeds ≤ 2.0% for floating or unbonded screeds • Calcium sulfate screeds without underfloor heating ≤ 0.5% • Calcium sulfate screeds with underfloor heating ≤ 0.3% The CM measurement is to be carried out in accordance with the current work instructions from the technical information of the FBH-AD “Coordination of cut out areas with heated floor constructions”.
Product preparation: Mix SOLOFLEX-FAST with clean water in a clean mixing bucket until homogenous. Mixing ratio: 1.8 – 2.0 litres water : 6 kg SOLOFLEX-FAST 7.5 – 8.5 litres water : 25 kg SOLOFLEX-FAST On horizontal external surfaces such as e.g. balconies and terraces, SOLOFLEX-FAST is to be modified with UNIFLEX-B. Furthermore we recommend the addition of UNIFLEX-B to SOLOFLEX-FAST when installing large format tiles greater than 60 x 60 cm. Modification with the UNIFLEX-B elastifier improves the deformability and tensile adhesion strength of SOLOFLEX-FAST. Dependent on the modification, class S2 can be achieved, which is especially recommended for large format tiles greater than 60 x 60 cm. This considerably compensates against shear stresses which can lead to de-bonding under unfavourable external conditions. To improve the workability, add water once the SOLOFLEX-FAST has been mixed with UNIFLEX-B. The addition of UNIFLEX-B will shorten the open time. The deformability to DIN EN 12004 is considerably increased so that class S2 is achieved. Mixing ratio: 2 kg UNIFLEX-B : 6 kg SOLOFLEX-FAST : approx. 0.5 litres water 8.33 kg UNIFLEX-B : 25 kg SOLOFLEX-FAST : approx 2.0 litres water After standing for 3 minutes, mix through once again. Do not mix more SOLOFLEX-FAST than can be used within the pot life. Spread SOLOFLEX-FAST adhesive onto the surface of the substrate and comb through with the appropriately sized notched trowel for the tile format. Install the finishing material within the open time. Always clean mixing containers as setting SOLOFLEX-FAST functions as an accelerator. Do not mix with other cement-based mortars.

Important advice: • Not suitable for underwater areas. • When installing natural or agglomerate stone always observe their specific product properties (tendency to discolour, risk of curling etc.) and the stone producer’s installation recommendations. We recommend that a test area is carried out. • To safely avoid curling effects caused by water absorption when installing serpentinite, slate and with agglomerate / synthetic stone which contain these natural stones, we recommend the use of ASODUR-EK98 or ASODUR-Design. • When installing agglomerate / synthetic stone we recommend that 25 kg SOLOFLEX-FAST is modified with 2.0 kg UNIFLEX-B. • When installing tiles or slabs to poured asphalt of hardness class IC10 we recommend that 25 kg SOLOFLEX-FAST is modified with 2.0 kg UNIFLEX-B. • Perimeter, bay, structural joints and movement joints are to be brought through or incorporated in the designed position and blocked with an appropriate medium e.g. edging strip RD-SK50. Saw cut joints are to be adhesively sealed or secured against uneven levels. • Thoroughly prime calcium sulfate based substrates such as ASO-NM15 with ASO-Unigrund-GE, ASO-Unigrund-S, ASO-Unigrund-K (mixing ratio 1:3 with water) or ASODUR-V360W. ASODUR-V360W has the greatest blocking effect of the substrate. To avoid the formation of ettringite with calcium sulfate based substrates, UNIFIX-AEK is suitable for tiling to these substrates up to residual moisture levels, measured with a carbide hygrometer, of 1.0% when heated and 1.5% when unheated. • When installing large format tiles greater than 50 x 50 cm, apply a scratch coat to the rear of the tile to improve adhesion, or fix using the floating-buttering method. • Do not re-life adhesives that has already started to harden, by adding more water or fresh adhesive as there is a risk of inadequate strength development.
• When installing tiles in heavy duty external areas (balconies/terraces) we recommend the installation of the highly elastic waterproof membrane system AQUAFIN-RS300, AQUAFIN-2K/M or AQUAFIN-2K. • In permanently wet areas (swimming pools, containers etc.) we recommend the use of the system thin bed adhesives UNIFIX-2K, UNIFIX-S3, UNIFIX-2K/6 onto the SCHOMBURG waterproof membrane suitable for the area of application. Observe the specific properties of the finishing products to be installed. • Protect areas where SOLOFLEX-FAST is not being used, from its effects. • Instead of ASO-Unigrund-GE, ASO-Unigrund-K diluted 1:3 with water can also be used. • SOLOFLEX-FAST is a hydraulic setting mortar that is to be protected from water and frost penetration until fully cured, which in adverse weather conditions can take a few days. • Direct contact between cement-based adhesives and magnesium screeds leads to destruction via chemical reaction. Therefore rising moisture from the substrate must be eliminated through appropriate measures. Mechanically roughen the magnesite surface and prime with the epoxy resin ASODUR-V360W with the addition of max. 5% water as necessary (approx. 250 g/m2). Wait for approx. 12 – 24 hours at +20 °C then apply a second coat of ASODUR-V360 (approx. 300 – 350 g/m2). Blind the second coat whilst it is still wet with an excess of 0.5 – 1.0 mm quartz. Wait for a further 12 – 16 hours before further work. • Follow the relevant current regulations.
