Substrate temperature: Storage: Packaging:
+5 °C to +30 °C frost free, cool, upright, protected from sunlight, loads and moisture, 12 months 15 m2 (width 1 m, length 15 m)
Substrate preparation: The substrate to be waterproofed must be dry, loadbearing and flat with a surface free from cracks and ridges and adhesion inhibiting substances such as e.g. oil, grease, hoar frost or paint. Ensure masonry work is flush pointed. Repair existing damage, defects or gravel nests in the concrete with ASOCRET-RN. Edges are to be chamfered, corners to be rounded off. Product application: 1. Internal corners, wall/floor junctions: Slurry with AQUAFIN-1K and whilst still wet, form a coved fillet using ASOCRET-M30. Once hardened overcoat this area, including the front face of the foundation slab. 2. Priming: Prime the substrate with ASOL-FE, diluted up to a max. of 1:1 with water, dependent on the absorbency of the substrate. Allow the primer coat to dry before subsequent bonding stages with the cold applied self adhesive waterproof sheet membrane. To assess the bond to the dried primer, stick a small strip of the sheet waterproof membrane to the primer, press down and rip off again. If more than 50% of the primer is pulled from the substrate, then the bond is still not adequate. Waterproofing with the sheet membrane must be carried out later. 3. Application: After removing the release paper from the KSKAbdichtungsbahn, bond, without folds or air pockets, to the correctly prepared, dry substrate and press down with force using a rubber roller or similar. Before installing to the main areas, apply a reinforcing strip, 20- - 30 cm wide of the KSK-Abdichtungsbahn to all edges, corners and chamfers. Install subsequent membrane with a minimum overlap of 5 cm. The membrane can also be butt-jointed dependent on the project or structure. Bond over the butt-joints with KSK-Abdichtungsbahn-FB. Membrane joints are to be secured against de-lamination or moisture migration
using rendering angles or covering strips. As an Alternative, the joints in the membrane can be secured with KSKAbschlussband (KSK connecting tape). Protective layers: Protect waterproof membranes in accordance with DIN 18195, part 10, from weathering e.g. strong sunlight, rain, frost and mechanical damage, through suitable protective layers e.g. protection and drainage boards. Protective layers may not exert any point or linear pressure on the waterproof membrane. Bond protection or drainage boards with COMBIDIC-1K, perimeter insulation in a full bed of COMBIDIC-2K. Drainage is to be in accordance with DIN 4095. Back-filling the building pit: Back-filling the building pit must be carried out in accordance with relevant guidelines. The back-fill material should be placed and compacted in layers. Ensure that the protection layer does not become damaged and that slippage is prevented. Advice: • Immediately prior to use, store the self adhesive waterproof sheet membrane at room temperature, approx. +20 °C and only apply in dry weather conditions. • Do not store the material in direct sunlight. • Do not apply to damp substrates. •N egative water pressure cannot be accommodated by bitumen waterproof materials. In areas where this is expected, waterproof beforehand with AQUAFIN-1K. • P rotect areas not being treated from the effects of KSKAbdichtungsbahn. •D o not bond or cover the self adhesive waterproof sheet membrane with products containing solvents.
