Dried on material can only be <br />removed with difficulty. <br />Substrate preparation: <br />The substrate must be free from frost, be load-bearing, <br />flat, with open porosity and have a closed surface. It must <br />be free from gravel pockets, blowholes, gaping cracks <br />and ridges, free from adhesion inhibiting material e.g. <br />dust, laitance layers and loose components. Undulations <br />> 5 mm as well as mortar pockets, rendering grooves <br />in brickwork or dense concrete blocks, open masonry <br />work joints, voids, substrates with large pores or uneven <br />masonry work are to be levelled up with ASOCRET-M30 <br />beforehand. Corners and edges are to be rounded or, <br />with concrete sections, to be chamfered post installation. <br />Mechanically remove laitance at the wall/floor transition. <br />Wall/floor junction and internal corners: <br />Pre-slurry the professionally prepared substrate with <br />AQUAFIN-1K or ASOCRET-M30 in a fluid consistency <br />and construct a coved fillet with ASOCRET-M30 to a <br />minimum edge height of 4 cm, whilst the slurry is still <br />wet. To protect against moisture migration from the rear, <br />overcoat the area above the base slab to a minimum <br />height of 20 cm with AQUAFIN-1K and over the front <br />face of the base slab down to a minimum of 10 cm. In <br />the exposure condition of standing seepage water, the <br />waterproofing layer must continue a minimum 15 cm <br />down. <br />Intersection: <br />In the exposure condition of ground moisture and nonstanding seepage water, intersections are to be provided <br />with a mineral-based coved fillet in ASOCRET-M30 <br />and, once dried, incorporated within the surface applied <br />waterproof membrane. In the exposure condition <br />water not under pressure or standing seepage water, <br />use adhesive bonded or loose/integral flanges at</p> <p>intersections and incorporate within the surface applied <br />waterproof membrane. <br />Splash zone / plinth area transition: <br />In the water splash zone, bring the waterproof membrane <br />to a minimum of 30 cm above the ground. Once <br />adjusted to the ground, the waterproof membrane must <br />reach at least 15 cm above ground level. As a rule, this <br />junction is treated with flexible waterproofing slurries, e.g. <br />AQUAFIN-RS300, in order to achieve a substrate with <br />bonding abilities for e.g. building skirt renders. Overlap <br />the bituminous coating min. 10 cm over the waterproofing <br />slurry. <br />Product preparation: <br />Thoroughly stir component A of COMBIFLEX-C2/P with a <br />slowly rotating drill and paddle (approx. 500–700 rpm). <br />Then add all of component A to the powder component <br />and mix intensively until a homogenous, lump free mass is <br />achieved. Mixing of part quantities is not possible. <br />Exposure conditions to DIN 18195 – part 4: <br />Apply COMBIFLEX-C2/P with a flat trowel in a minimum <br />of 2 coats. To achieve an even thickness, ideally comb <br />out with an appropriate sized notched trowel and then <br />form a tight surface with the flat edge of the trowel. <br />Always apply wet in wet. The dry film thickness must be a <br />minimum of 3 mm. <br />Lay the ASO-System-Fleece-02 onto the fresh <br />COMBIFLEX-C2/P waterproofing layer without overlaps <br />and using a smooth trowel or roofers brush, smooth flat. <br />It is standard practice to use the ASO-System-Fleece-02 <br />with concrete constructions. <br />Exposure conditions to DIN 18195 – part 5: <br />Apply COMBIFLEX-C2/P with a flat trowel in a minimum <br />of 2 coats. Incorporate ASO-reinforcing fabric into the <br />wet first coat of the waterproof membrane at coves <br />and edges. Allow to dry sufficiently before applying the</p> <p>2/4</p> <p>22/17</p> <p>next coat to avoid damaging the first coat. The dry film <br />thickness must be a minimum of 3 mm. Lay the <br />ASO-System-Fleece-02 onto the fresh COMBIFLEX-C2/P <br />waterproofing layer without overlaps and using a smooth <br />trowel or roofers brush, smooth flat. <br />Exposure conditions to DIN 18195 – part 6: <br />Apply COMBIFLEX-C2/P with a flat trowel in a minimum <br />of 2 coats. Incorporate ASO-reinforcing fabric into the <br />wet first coat of the waterproof membrane. Allow to <br />dry sufficiently before applying the next coat to avoid <br />damaging the first coat. The dry film thickness must be a <br />minimum of 4 mm. Lay the ASO-System-Fleece-02 onto <br />the fresh COMBIFLEX-C2/P waterproofing layer without <br />overlaps and using a smooth trowel or roofers brush, <br />smooth flat. <br />Assessing the waterproof membrane: <br />Always carry out a thickness check and document <br />results. In exposure conditions to DIN 18195, parts <br />5 and 6, it is mandatory to measure and log the wet <br />film thickness and drying. The film thickness is checked <br />whilst wet by measuring the wet film thickness (at least <br />20 measurements per building project or at least 20 <br />measurements per 100 m2 ). Spread the measuring <br />points out diagonally. Dependent on their presence within <br />the structure, the frequency of measurements should be <br />increased e.g. in areas of intersections, transitions and <br />junctions. When installing to DIN 18195, part 6 both <br />film thicknesses are to be checked separately. Evaluation <br />of drying as well as the dry film thickness is carried out <br />with a destructive reference sample using the wedge cut <br />method. The reference sample consists of the material <br />from the project substrate (e.g. masonry work, concrete <br />paving slab), which will be embedded in the building pit.</p> <p>Drainage and protection boards: <br />Waterproof membranes are to be protected from <br />weathering and mechanical damage using suitable <br />protective measures or layers in accordance with <br />DIN 18195, part 10. Protective layers may not exert any <br />point or linear loading on the waterproof membrane. <br />Dimpled sheets without a protective layer or corrugated <br />protective boards are therefore not suitable. Only place <br />protective layers once the waterproofing coat has fully <br />dried through. Protection and drainage boards can be <br />fixed on dabs with perimeter insulation being bonded <br />butt jointed in a full bed of COMBIDIC-2K-PREMIUM or <br />COMBIDIC-2K-CLASSIC. Install drainage to DIN 4095. <br />Back-filling the building pit: <br />Back-filling the building pit is only carried out once the <br />bituminous coating is fully dry and must be carried out <br />following relevant guidelines. Place and compact the <br />back-filling material in layers, ensuring that damage and <br />slippage within the protective layers is prevented.</p> <p>3/4</p> <p>22/17</p> <p>Important advice: <br />• Protect areas not being treated with COMBIFLEX-C2/P. <br />• Do not install when it is raining, where there is <br />impending rain or where the air and substrate <br />temperature is below +5 °C. <br />• Bitumen coatings cannot stand negative hydrostatic <br />pressure. In areas where this is expected, a protective <br />coating of AQUAFIN-1K must first be applied. <br />• Protect masonry work capping and open window <br />parapets from penetrating water. <br />• The minimum film thickness may never fall below the <br />prescribed value at any point! <br />• The required wet film thickness may not be exceeded <br />by 100% and may not fall below the required minimum <br />at any point. <br />• In accordance with recognised technical <br />regulations undertake waterproofing measures with <br />AQUAFIN-RS300 or AQUAFIN-2K/M beneath rising <br />walls and on the base slab. <br />• Protect COMBIFLEX-C2/P from weathering e.g. rain, <br />frost, strong sunshine etc. until fully dried out. <br />** Bituminous coatings may only be used for applications in <br />accordance with DIN 18195, which have been approved in the <br />relevant section of the standard. At this time, applications according <br />to DIN 18195, part 6, – water under pressure – is not permitted. <br />Therefore such applications are to be contractually agreed between <br />client and applicator and, in accordance with VOB part C, DIN <br />18336, clearly and separately entered into the technical specification. <br />Please refer to the information in the “Guidelines for planning and <br />implementation of waterproofing measures with polymer modified <br />bituminous coatings”, Deutsche Bauchemie e.V.</p> <p>Please observe a current valid EU Safety Data Sheet. <br />GISCODE: BBP 10</p> <p>This technical data sheet is a translation from German and does not consider local building codes or legal requirements.
