Areas of application: For the installation of natural and synthetic stone tiles with high or low water absorption as well as for earthenware and vitrified ceramic finishes. Preferred when work is under time constraints and for the installation of light coloured, translucent material and those prone to discoloration such as e.g. crystalline marble, limestone, granite, porphyry, quartzite, sandstone to name a few. With its ability to speedily bind the mix water, CRISTALLIT-FLEX offers additional protection against discoloration resultant from the stone’s own constituents. CRISTALLIT-FLEX is suitable for a secure bond to concrete, render/plaster, masonry work, moisture resistant plasterboard etc., and for use on

Product preparation: Mix CRISTALLIT-FLEX in a clean mixing bucket with clean water until homogenous. Mixing ratio: 1.2 – 1.5 litres water : 6.0 kg CRISTALLIT-FLEX 5.0 – 6.0 litres of water : 25 kg CRISTALLIT-FLEX Allow to stand for a short period, then re-mix. Do not mix more adhesive than can be used within approx. 60 minutes*. Spread the mixed adhesive over the substrate surface and comb through with a notched trowel appropriate to the tile size. Install the tiles within the adhesive open time. Always clean mixing containers, as CRISTALLIT-FLEX, which is setting acts as an accelerator. Do not mix with cement-based adhesives.
Storage: dry, 12 months when stored in the original unopened packaging. Use opened packaging promptly. Substrate preparation: CRISTALLIT-FLEX is suitable for the assured installation to all substrates covered in DIN 18157, part 1 e.g. concrete, aerated concrete, render/plaster, poured asphalt of class IC10, cement-based and calcium sulphate based screeds, heated screeds, masonry work and moisture resistant plasterboard etc. The substrate must be dry, load-bearing, adequately flat, be free from penetrating cracks and separating substances such as oils, paints, laitance and loose areas. It must have a closed surface texture and exhibit surface characteristics and strength consistent with its type. When installing tiles, the substrate, its preparation and workmanship must conform to DIN 18157, part 1. Roughen smooth concrete surfaces, prime absorbent substrates with ASO-Unigrund. Calcium sulphate screeds must be abraded, vacuumed and as with all calcium sulphate based substrates, primed with ASO-Unigrund. When installing large format tiles on calcium sulphate screeds, we recommend priming with ASODUR-V360W due to its increased barrier effect. Prior to the installation of tiled finishes on to heated screeds, they must be commissioned to recognised technical regulations. The readiness of a substrate to receive finishes is to be determined by moisture measurements using a carbide hygrometer (CM devce). The moisture content should not exceed: • CT 2.0 CM% for screeds on insulation or separating layers • CA without underfloor heating 0.5 CM% • CA with underfloor heating 0.3 CM% The moisture measurements are to be carried out in accordance with current FBH-AD work instructions taken from the technical information on the coordination of cutout points with heated floor constructions.
On horizontal external surfaces, e.g. balconies and terraces, CRISTALLIT-FLEX is hardened with UNIFLEX-F in the following mix ratio: 8.33 kg UNIFLEX-F : 25 kg CRISTALLIT-FLEX : approx. 2.25 l water For laying ceramic tiles (large format) in highly thermally stressed and other highly stressed areas, the use of a tile adhesive with higher deformability class S2, e.g. UNIFIX-S3 or UNIFIX-S3-fast, is recommended. CRISTALLIT-FLEX can be used to produce a highly deformable adhesive mortar of class C2, deflection > 5 mm (corresponds to S2) with the following mix ratio when UNIFLEX-F is added: Mixing ratio: 8.33 kg UNIFLEX-F : 25 kg CRISTALLIT-FLEX : approx. 2.25 l Wasser *) These values relate to +23° C and 50% relative humidity
Advice: • Not suitable for use in underwater areas. • To avoid curling effects through water absorption, we recommend when fixing serpentinite, slate or agglomerate/synthetic stone which contain these
2/3
natural stones, that ASODUR-EK98 or ASODUR-DESIGN is used. • When installing agglomerate/synthetic stone we recommend that 25 kg CRISTALLIT-FLEX is modified with 2.5 kg UNIFLEX-F. • When CRISTALLIT-FLEX is modified with UNIFLEX-F the setting process is altered, delaying the time before grouting and foot traffic is permitted. • When installing large format tiles greater than 50 x 50 cm, butter the backs of the tiles or use the buttering/floating technique to improve adhesion. • When fixing natural and synthetic stone, take the specific properties of the product into consideration (tendency to discolour, risk of curling). We recommend that a trial area is fixed. • Thoroughly prime calcium sulphate based substrates, such as e.g. ASO-NM15, with ASO-Unigrund-GE or ASO-Unigrund-K (mix ratio 1:3 with water). To avoid the formation of ettringite, UNIFIX-AEK is especially suited for installing tiles to calcium sulphate based substrates up to a residual moisture of 1.0% when heated and 1.5% when unheated (carbide hygrometer measurements). Take the specific properties of the product to be installed into consideration. • Adhesive, which has started to stiffen, should not be re-lifed through the addition of water or fresh mortar as there is a risk of inadequate strength development. • When installing tiles in more demanding conditions externally (balconies and terraces), we recommend waterproofing with the highly elastic membranes AQUAFIN-TBS. • In continuously wet areas (swimming pools, water features etc.), we recommend the use of system thinbed adhesives UNIFIX-S3 over the SCHOMBURG waterproof membrane, appropriate for the conditions. Consider the specific properties of the material to be installed. • Protect areas not being treated from the effects of CRISTALLIT-FLEX. • Direct contact between cement-based adhesives and magnesite screeds leads to the destruction of the
magensite screed through chemical reaction. Prevent moisture ingress from the rear using suitable means. Mechanically abrade the magnesite substrate and prime with the epoxy resin ASODUR-V360W mixed with max. 5% water as necessary (approx. 250 g/m²). After waiting from between 12 to 24 hrs at +20° C, apply a second coat of ASODUR-V360W (approx. 300 – 350 g/m²). Blind the second coat, whilst still wet, with 0.5 – 1.0 mm quartz sand. Wait for a further 12 – 16 hours then continue with the installation. • Observe the relevant current regulations. E.g.
