Technical Datasheet ASO®-Tape Preparing the surface 1. 2. 3. 4.
The substrate may be matt damp. Water puddling is not permissible. For substrates other than concrete, the suitability must be checked in advance by carrying out a trial adhesion. In the case of strip joint seals, the concrete must have water tight properties. Otherwise, the joint waterproofing must be combined with a suitable area waterproofing.
Usage Construction joints / strip-form waterproofing 1. Apply ASODUR-K4031 at least 1 cm wider than the joint tape on both sides of the joint to be bridged. 2. The joint tape is then inserted and meticulously embedded in the adhesive layer with a trowel or pressure roller, with no wrinkles or voids, and trowelled on top with ASODUR-K4031. 3. The joint strips must be fully embedded. 4. The adhesive and filler layer thickness should not be less than 1 mm each. 5. Joint-Tape edges can be glued with an overlap of at least 5 to 10 cm or, alternatively, hot-air welded.
Movement joints 1. Apply ASODUR-K4031 at least 1 cm wider than the joint tape on both sides of the joint to be bridged. 2. The joint tape is then inserted and meticulously embedded in the adhesive layer with a trowel or pressure roller, with no wrinkles or voids, and trowelled on top with ASODUR-K4031. 3. To accommodate movements, an unbonded expansion area must be provided in the joint area. 4. Movement joints are always applied with 2 mm ASO-Tape and can be laid flush or looped depending on the project. 5. Depending on the installation and load situation (e.g. overhead application or negative water pressure), a support or protective structure may be required. 6. The adhesive and filler layer thickness should not be less than 1 mm each. 7. Seal joint-tape edges with overlap of at least 5 to 10 cm by hot-air welding.
Hot air welding 1. 2. 3. 4. 5.
The joint strips are cut to size for the project (butt or corner joint) and laid on a level substrate. Prods are to be overlapped with >5 cm. In case of water pressure > 2 bar, overlap the prods with > 20 cm. The overlap area is roughened and cleaned with sandpaper. The welding temperature (reference values: approx. +300 °C to +350 °C) must be set by a test weld. Place the joint strip prods on top of each other to fit and fix them in place by spot welding in the edge area. This prevents slippage during welding. 6. Then the wide nozzle of the hot air tool is pulled slowly and evenly through the overlap area and joined together to ensure coverage over the whole area with the pressure roller. 7. Before installation, the welds must be checked again for a complete, tight bond.
Storage conditions Storage Cool, dry, protected from sunlight. Min. 12 months in the original container.
Disposal Product leftovers can be disposed of in household waste.
Notes Unlike Hypalon joint sealing tape strips, ASO-Tape does not need to be additionally activated and must not be brought into contact with solvents. The joint tape must be protected against mechanical damage by suitable protective measures. With negative water pressures > 0.5 bar, a suitable support structure (apron plate) is essential.
The recognised standards of construction engineering, the relevant guidelines and current regulations must be observed.
