Using Aquaseal NEO is easy. First, clean the area you want to repair to make sure it's free of dirt and grease. Then, apply a thin layer of the contact cement evenly on both surfaces that need to be bonded. Let it dry for a short while until it's tacky. Press the two surfaces together firmly and hold for a bit. You can expect the repair to be done within half an hour. As for precautions, keep it away from open flames and heat sources as it's a flammable product. Store it in a cool, dry place. When it comes to maintenance, if there's any leftover cement on tools, clean it off with an appropriate solvent right away. This way, you can keep your Aquaseal NEO working well for a long time.
