10. Repairs of tanks and areas around fittings call for similar techniques. Accidental small fractures and leaks can be repaired by you. However, large areas of damaged to tanks sometimes required exterior structural reinforcement and the services of a Bittner field crew.

The procedures are the same as those for welding pipe. Prepare surface, catalyze the resin, apply mat and finish with gel coat.

When patching, cut each succeeding piece of mat larger than the one preceding it. The patch should be equal or exceed the wall thickness of the object being repaired.

If you have any questions regarding welding or simple patching, call Bittner Industries. We will be glad to assist you with your particular problem.
