A two part epoxy glue, it comes as two nearly equal containers of paste. It is fully water proof. Equal parts of each are mixed together. This gives a white thixotropic paste which will adhere tenasciously to nearly anything and which is also able to fill large gaps and maintain strength across them. The amount of part A and Part B to be mixed can be judged by eye to be nearly equal. The 1 kgm kit has a 520 gram container of resin and a 480 gram container of hardener. Epox-E-Glue will adhere to most things provided proper surface preparation has been done. Some plastics and some metals require special surface preparation.
