It is additionally suitable for <br />waterproofing transitions or differing building <br />materials. <br />3.2 Surface preparation: <br /> The substrate must be clean and load-bearing as <br />well as free from adhesion inhibiting materials. At <br />the time of installation it may be matt damp but <br />not wet or with saturated pores. In the area to be <br />waterproofed, mechanically prepare the substrate <br />using suitable means e.g. planing, scabbling or <br />grit blasting etc., in order to ensure a good bond. <br />When using on substrates other than concrete, <br />assess with a trial adhesion test. When applying <br />joint waterproofing as strips it is essential that the <br />concrete has waterproof qualities. Otherwise the <br />joint waterproofing must be used in combination <br />with a surface-applied waterproof membrane <br />3.3 Application: <br /> Coat the prepared substrate on both sides of the <br />joint to be bridged with ASODUR-K4031 to a</p> <p>2/3</p> <p>07/20</p> <p>width min. 1 cm wider than the ASO-Tape being <br />used. Then lay the joint tape and thoroughly bed <br />into the adhesive layer with a trowel or pressure <br />roller without voids or folds and coat over the top. <br />In so doing, ensure that the joint tape is <br />completely bedded. The adhesive or smoothing <br />coat thickness should never be less than 1 mm. <br />Overlap butt joints by a min. of 5 to 10 cm and <br />bond or alternatively hot air weld.</p> <p>3.4 Cleaning: <br /> During continued application, all tools must be <br />regularly & thoroughly cleaned with water and/ <br />or solvent (ASO-R001) every 25 to 40 minutes <br />(dependant on temperature) to prevent the product <br />from setting on tool surfaces. Thorough cleaning <br />must also be carried out immediately at the end of <br />works or whenever work is suspended.</p> <p>3.3.1 Movement joints: <br /> <br />Movement joints always require a 2 mm joint <br />tape and can either be laid flush or in a loop <br />dependent on the project. To accomodate <br />movement, leave an unbonded section of tape in <br />the expansion area. Dependent on the installation <br />and loading e.g. overhead use or negative water <br />pressure, a reinforcing or supporting construction <br />may be necessary. <br />3.3.2 Hot air welding: <br /> The joint tapes are cut to suit the project (butt joints <br />or corner joints) and laid on a flat substrate. Butt <br />joints are to be overlapped by a min. 5 cm. The <br />overlap area is to be roughened with abrasive <br />paper and cleaned. Welding is carried out with <br />hot air equipment with a wide nozzle and a <br />pressure roller. The welding temperature (reference <br />values: approx. 300–350 °C) is to be set by a <br />trial weld. The joints in the tapes are laid on <br />top of one another appropriately and fixed at the <br />edges by selective welding in order to prevent <br />slipping during welding. Then the wide nozzle of <br />the hot air tool is drawn slowly and evenly over <br />the overlap area and fully joined together with a <br />pressure roller. Before installing check the weld for <br />a complete watertight bond.</p> <p>The rights of the buyer with regard to the quality of our materials are based on our terms and conditions of sale and delivery.
