Frost-free <br />2. Load-bearing <br />3. Even <br />4. Pore open <br />5. Sealed in the surface <br />6. Free of adhesion inhibiting substances</p> <p>Preparing the details <br />1. Edges are to be chamfered and corners are to be rounded. <br />2. Depressions > 5 mm and mortar pockets, plaster grooves in brickwork, open butt or bed joints, damaged areas, large pored substrates or <br />uneven masonry work must be levelled in advance with ASOCRET-M30.</p> <p>Wall/floor transitions, internal corners, joints <br />1. Pre-screen the professionally prepared substrate with AQUAFIN-1K or ASOCRET-M30 featuring consistency that can be screened, and install a <br />sealing cove of ASOCRET-M30 with an edge height of at least 4 cm while it is still wet. <br />2. In the area of structural movement joints, the waterproofing is reinforced with ADF-Dehnfugenband (Expansion-Joint-Tape) or ASO-Joint-Tape2000-S and integrated in the area waterproofing.</p> <p>Intersections <br />1. Intersections must be connected to the pipes or casing pipes by means of sealing coves. Alternatively, depending on the nominal diameter, ASODichtmanschette-Boden, ASO-Dichtmanschette-Wand or ADF-Rohrmanschette can be used. <br />2. In the water exposure class W2.1-E and W3-E, intersections with suitable adhesive or loose / fixed flange constructions are to be used and <br />integrated into the area waterproofing. <br />3. The following area is to be waterproofed and must be carried out at least 5 cm onto the pipe penetration. <br />4. In accordance with the specifications of DIN 18533, an increased dry film thickness of 5 mm must be applied in the area of the flange <br />constructions. The use of spacers must ensure that the layer thickness does not fall below 4 mm after the loose flange has been clamped.</p> <p>Splash water zone / plinth area <br />1. In the area of the splash water zone, the waterproofing must be run a minimum 30 cm above the ground. <br />2. After being adjusted to the ground, the waterproofing must reach ≥ 15 cm above ground level. <br />3. As standard, this connection is established with flexible, cementitious waterproofing slurry, e.g. AQUAFIN-RB400, in order to achieve an <br />adhesive substrate, e.g. for building skirt renders, etc. <br />4. The overlapping of the bituminous thick layer coating on the waterproofing slurry is min. 10 cm here</p> <p>SCHOMBURG GmbH & Co. KG · Aquafinstr. 2–8 · D-32760 Detmold (Germany) · Tel. +49-5231-953-00 · Fax +49-5231- 953-333 · schomburg.com <br />3/6</p> <p>19/12/2025</p> <p>Technical data sheet <br />COMBIDIC®-2K-CLASSIC <br />Application <br />Mixing <br />1. Stir the bitumen component briefly with a stirrer. <br />2. Completely add the powder to the bitumen component and mix until homogeneous and free from lumps. <br />3. The hardener must be distributed evenly.</p> <p>Application <br />1. Prepare the substrate with a primer coat of ASOL-FE (diluted 1:5 with water). <br />2. In the case of very absorbent concrete substrates, a scratch coat is recommended to avoid the formation of air bubbles in the bituminous thick <br />layer coating. <br />3. After complete drying of the primer / scratch coat, COMBIDIC®-2K-CLASSIC can be applied.</p> <p>Water exposure class W1.1-E and W1.2-E <br />1. Apply COMBIDIC®-2K-CLASSIC with a flat trowel in min. 2 application steps. <br />2. A fully covering scratch coat can be applied as the first layer. <br />3. To achieve an even layer thickness, ideally comb with a toothed trowel or coating thickness trowel of the appropriate size and form a sealed <br />surface with the smooth side of the toothed trowel. <br />4. Application takes place while the product is still wet. <br />5. In the area of the base slab, the waterproofing must be run at least 10 cm down the end face of the sill.</p> <p>Water exposure class W2.1-E and W3-E <br />1. Apply COMBIDIC®-2K-CLASSIC with a flat trowel in min. 2 application steps. <br />2. The ASO®-Verstärkungseinlage is to be installed on the fresh first waterproofing layer. <br />3. Before applying the second layer, the first layer must have dried sufficiently to exclude damage by the following layer. <br />4. In the area of the base slab, the waterproofing in water exposure class W2.1. must be run at least 15 cm down the end face of the sill.</p> <p>Testing the waterproofing <br />A layer thickness check should always be carried out and documented. The layer thickness check is carried out in the fresh condition by <br />measuring the wet film thickness (at least 20 measurements per building project or at least 20 measurements per 100 m²). Drying / the dry film <br />thickness is destructively tested using the wedge cut method on a reference sample consisting of the project substrate stored in the building pit.</p> <p>Back-filling of the building pit: <br />Back-filling the building pit can take place after the bituminous thick layer coating is totally dry.</p> <p>Cleaning tools <br />Rinse tools with water immediately after use. Dried material is difficult to remove.</p> <p>Drainage and protection boards for building components in direct contact with the ground <br />The waterproofing must be protected against weathering influences and mechanical damage using suitable protective measures in accordance <br />with DIN 18533. 1. The waterproofing must be totally dry. 2. Suitable protection and drainage boards can be fixed in place with COMBIDIC1K/-S in batches. 3. Perimeter insulation must cover the whole area and be butt jointed with COMBIDIC-2K-CLASSIC or COMBIDIC-2KPREMIUM. 4. Drainage is carried out in accordance with the specifications of DIN 4095.</p> <p>Storage conditions <br />Storage <br />Store in a frost-free, cool and dry place. At min. 5 - 40 °C for 12 months in the original canister. Promptly use opened container.</p> <p>Notes <br />Protect surfaces that are not to be treated from the effects of COMBIDIC®-2K-CLASSIC! <br />Negative water pressure cannot be absorbed by bituminous waterproofing. It is necessary to apply waterproofing with AQUAFIN®-1K <br />beforehand in the areas in which this can be expected. <br />Do not apply during rain or with air / substrate temperatures below +5 °C. <br />Protect masonry work tops and open window parapets against water penetration. <br />The load case-specific minimum film thickness must not be undershot at any point at the time of acceptance! <br />The required wet film thickness must not exceed 100% at any point. <br />Protect COMBIDIC®-2K-CLASSIC from weathering influences such as rain, frost, strong solar radiation, etc. until totally dry!</p> <p>SCHOMBURG GmbH & Co.
