A concrete covering of > 8 cm should be carried out to the water-conducting side. <br />2. Glue AQUAFIN®-CJ4 with mounting adhesive for swellable waterstops. The concreting process can take place no sooner than 8 hours after <br />adhesion. <br />3. Alternatively, AQUAFIN®-CJ4 can also be fastened with steel nails (min. 5 nails/m). When doing so, it must be ensured that it is pressed onto the <br />substrate over the entire area. <br />4. Avoid looping and cavities. <br />5. Swelling tape connections can be applied with an overlap of at least 5 cm or butt-jointed. <br />6. Butt-jointed swelling tape connections must be secured with a separate swelling tape with an overlap of at least 3 cm.</p> <p>Storage conditions <br />Storage <br />Cool, dry, protected from sunlight. Min. 5 years in the original canister.</p> <p>Notes <br />The swellable waterstop must be subjected to a visual check before concreting. Heavily pre-swollen joint sealing tapes are unsuitable and <br />must be removed. <br />A concrete covering of min. 8 cm must be complied with. <br />Swellable waterstops must be protected against floating and slipping in all areas.</p> <p>Explanations <br />Conformity / Declaration / Verification</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.
