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 in consistency that can be screened, and install a coved <br />fillet 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. The following area is to be waterproofed and must be carried out at least 5 cm onto the pipe penetration.</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>Application <br />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®-1K can be applied. <br />4. We recommend homogenising COMBIDIC®-1K before application. <br />5. Apply COMBIDIC®-1K with a flat trowel in min. 2 application steps. <br />6. 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 />7. Application takes place while the product is still wet. <br />8. The dry film thickness must be at least 3 mm. <br />9. 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>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>SCHOMBURG GmbH & Co.

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.

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®-1K from weathering influences such as rain, frost, strong solar radiation, etc. until totally dry!</p> <p>Observe applicable safety data sheet! <br />Explanations <br />Conformity / Declaration / Verification</p> <p>SCHOMBURG GmbH & Co.
