Using Aquaseal FD is easy. First, clean the area you want to repair to make sure it's free of dirt and debris. Then, apply a thin layer of the adhesive to both surfaces you're joining. Press them together firmly and let it dry according to the instructions on the package. When using it as a seam sealer, apply it evenly along the seams. As for maintenance, keep the adhesive in a cool, dry place. Make sure the cap is tightly closed after each use to prevent it from drying out. Also, avoid using sharp objects on the repaired areas to protect the bond. If you get the adhesive on your skin, wash it off with soap and water right away.
