Processing equipment Aids/tools Scissors/knife Pressure roller
Preparing the substrate Requirement for substrate 1. Dry 2. Load-bearing 3. Even 4. Sealed in the surface 5. 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 data sheet KSK-Abdichtungsbahn Application 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. A minimum overlap of 10 cm is required for connections. 6. 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. 7. 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 canister.
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.
