Application technology Aids/tools Scissors/knife Pressure roller
Substrate preparation Requirement for substrate 1. 2. 3. 4. 5.
Dry Load-bearing Even Sealed in the surface Free of adhesion inhibiting substances
Preparing the surface 1. Apply primer consisting of ASOL-FE (diluted 1:1 with water). 2. The primer must be completely dry / must have reacted fully before the subsequent work steps are carried out. 3. For transitions to cementitious waterproofing, e.g. AQUAFIN-RB400, a primer can be omitted.
Preparing the details 1. Edges are to be chamfered and corners are to be rounded. 2. Depressions > 5 mm and mortar pockets, plaster grooves in brickwork, open butt or bed joints, damaged areas, large pored substrates or uneven masonry work must be levelled in advance with ASOCRET-M30 (cement-based mortar). 3. Negative water pressure cannot be absorbed by KSK-Abdichtungsbahn. Waterproof areas where this is expected with AQUAFIN®-1K. 4. Pre-screen internal corners / floor transitions with AQUAFIN®-1K or ASOCRET-M30 in a consistency that is able to screen. Apply a coved fillet while still wet using ASOCRET-M30. After curing, recoat the area including the base slab face with AQUAFIN®-1K.

Technical Datasheet KSK-Abdichtungsbahn Usage Application 1. Bond all joints, edges, corners and coves with an approx. 30 cm wide reinforcing strip of KSK waterproofing sheet FB / KSK waterproofing sheet before laying over the entire surface. 2. Cut KSK-Abdichtungsbahn to the desired length. 3. Peel off the release film on the back and stick it to the end of the waterproofing membrane with an overlap of ≥ 8 cm and press on firmly. 4. Press the sheet down firmly, free of wrinkles and air bubbles. 5. Alternatively, butt joints can be covered with KSK waterproofing membrane FB. 6. A minimum overlap of 10 cm is required for connections. 7. The ends of the sheets must be secured against detachment or moisture penetration by means of plastering rails or cross-cut strips. Alternatively, the ends of the sheets can be secured with KSK finishing tape. 8. Protective, drainage or insulation boards can be glued with COMBIDIC®-2K-CLASSIC or COMBIDIC®-2K-PREMIUM.
Storage conditions Storage Cool, dry, protected from sunlight. Min. 12 months in the original container.
Disposal Hand over product residues to approved disposal companies.
Notes Protect surfaces that are not to be treated from the effects of KSK-Abdichtungsbahn! Store KSK-Abdichtungsbahn at room temperature (approx. +20 °C) until immediately before applying and only apply in dry weather. Do not store or apply KSK-Abdichtungsbahn in direct sunlight. Do not apply KSK-Abdichtungsbahn to damp substrates. KSK-Abdichtungsbahn may not be glued or overcoated afterwards with products containing solvents.
