What is true concerning the repair of fiberglass tanks?

1. Small fractures may be repaired with epoxy

2. Fiberglass cloth dimensions must be at least 12 x 12 inches

3. A second layer of fiberglass cloth is not required

4. Testing for tightness is required after 60 days

The correct answer is: A second layer of fiberglass cloth is not required

The assertion that a second layer of fiberglass cloth is not required holds true in specific cases when repairing fiberglass tanks. In many instances, a single layer may be sufficient to effectively seal small cracks or damages that do not compromise the structural integrity or the primary function of the tank. When applying a repair, factors such as the extent of damage, the type of resin used, and the manufacturer's guidelines play a crucial role in determining whether additional layers are necessary. Careful evaluation of the damage is paramount; for minor repairs, a single layer may provide adequate strength and seal. This option indicates an understanding that repairs must be tailored to individual circumstances, which is essential in maintaining the tanks' safety and functionality. On the other hand, certain conditions might indeed require additional layers for more extensive damage or for ensuring compliance with safety standards. Therefore, the approach to fiberglass tank repairs is not one-size-fits-all, allowing for discretion in whether additional layers are needed based on the situation at hand.
