• Is Rapp-it only a temporary measure, or can the pipe repair system be used as a permanent repair?
• Rapp-it is primarily intended as a temporary pipe repair for onsite emergency situations. However, Rapp-it has been known to last many years, providing sound structural pipe repairs. Ultimately, this is up to the discretion of the user.

• If the leaking pipe cannot be isolated, can Rapp-it Pipe Repair still be used?
• Yes, Rapp-it can be used to stem the flow of the pipe leak until an alternative procedure can be completed.

• If the pipe has a small leak and is unable to be completely dry, can Rapp-it be used?
• Absolutely. Rapp-it Pipe Repair is ideal for use in wet applications.

• Can Rapp-it Pipe Repair be used underwater?
• Yes, both Rapp-it Pipe Repair Bandage and Rapp-it Steel Putty can be used underwater in either fresh or sea water. The curing time may vary due to insert temperature of water.

• What is the recommended thickness of Rapp-it?
• We suggest the thickness of the Rapp-it Pipe Repair Bandage to be a minimum of 10mm.

• What is the curing time for Rapp-it Pipe Repair Bandages?
• The curing time is approximately 30 minutes.

• Is Rapp-it Pipe Repair suitable for use on pipes with larger diameters
• A Rapp-it Bandage application involves a mechanical bind as well as a chemical adhesion. When applying Rapp-it, it is important that the bandage is pulled extremely tightly around the circumference of the pipe. This ensures a strong mechanical repair, resulting in a more successful application. However, on larger diameter pipes less torque can be applied and therefore this can result in a less suitable pipe repair. By using multiple bandages, greater internal pressure ratings may be achieved on larger diameter pipes.

• Can pipe repairs be done using the bandage only?
• Yes, although a combination of Rapp-it Steel Putty along with the bandage should produce a more successful pipe repair.

• What is the best way to remove an old application of Rapp-it Pipe Repair?
• Rapp-it Pipe Repair Bandages can be removed with a hacksaw or angle grinder once the repair is no longer required. When using an angle grinder, always use a respirator during the removal. Hammer and coal chisel is also an effective method of removing the bandage.

• Does Rapp-it have an expiry date?
• Rapp-it's shelf life is approximately 2 years from date of purchase if stored below 25°C (77°F), and the foil pouch is not punctured.
