Fast-acting, emergency pipe repair bandages.
The Rapp-it Pipe Repair System includes:
A woven fiberglass bandage impregnated with water-activated polyurethane resin and a 90mm stick of Rapp-it Steel Putty. A successful pipe repair can be achieved in only 30 minutes.
Shut down pipes or hoses. Apply gloves, then thoroughly clean and roughen the damaged area with a metal file or wire brush. This helps result in a successful repair.
Tear off adequate amount of Steel Putty. Twist and knead until it is a uniform grey colour and apply firmly into damaged area. Putty has a 2-5 minutes work time, and bandage application must begin during this time.
Open foil pouch and soak bandage in fresh temperate water (approximately 22-26°C / 71-79°F) for 10-20 seconds. Squeeze bandage 1-2 times while in water to help activation.
Quickly wrap the bandage around damaged area, extending 50mm (2″) either side of the leak. Pull each layer firmly throughout the application. A strong, tight repair is very important.
With wet gloves, squeeze the bandage with a rotating motion until resin stops foaming and is set. Allow a minimum of 30 minutes for Rapp-it Bandage to set rock-hard.
Are you prepared for your next repair? Ensure you have Rapp-it on hand at all times.
For best results, the completed bandage application should be no less than 10mm thick (12-15 wraps).
Allow 30 minutes for Rapp-it Pipe Repair System to set rock-hard. A longer curing time may result in a better repair.
Prepare piping as best as possible: Clean off all foreign matter; file down with emery paper, file, rasp or similar to allow best possible adhesion of both the putty and the bandage to the pipe or hose.
Bandage has a 2-5 minute work life, with full cure in 30 minutes. Water temperature can affect the bandage cure time. Colder water will increase the cure time and hot water will reduce the cure time.
When applying to damp, wet or slowly leaking areas, work Rapp-it Steel Putty forcefully into the surface and apply pressure until adhesion begins to take effect.
Putty has a 4-5 minute work life, forming a tenacious bond in 10 minutes, and a functional cure in 30 minutes.
First wraps must be wrapped as tightly as possible to ensure the adhesion to pipe and interface with the putty.
Rapp-it Steel Putty can be kneaded by hand and then moulded into a variety of shapes to fill cracks and holes.
Ensure putty is fully mixed until it is a consistent dark grey colour – no zebra striping; no patchwork colours. Putty will become hot.
For applications where pipes cannot be shut down, the effectiveness of the repair may vary. Please contact our office for specific advice.
Difficult or large applications may require multiple bandages.
Rapp-it is easy to use, but we know you have lots of questions
Here are some of the most common questions. If you don’t find what you're looking for here, click contact us to speak with our specialist.
Rapp-it is intended as a temporary pipe repair for onsite emergency situations. Ultimately, usage and suitability of application is up to the discretion of the user.
Yes, Rapp-it can be used to stem the flow of the pipe leak until an alternative procedure can be completed. Isolating the pipes is the most effective repair however we understand this cannot always be done. In that instance simply turn down the pressure as low as possible. Contact our office for advice.
Absolutely. Rapp-it Pipe Repair is ideal for use in wet applications. We suggest the pipe be cleaned and roughened first to ensure a successful repair.
Yes, both Rapp-it Pipe Repair Bandage and Rapp-it Steel Putty can be used underwater in either fresh or salt water. Curing time may vary according to the temperature of the water. Cold water will slow the cure time, and warmer water will result in a faster cure time.
Our recommended Rapp-it repair thickness is a minimum of 10mm or approximately 12-15 wraps around the pipe. We also recommend the repair extends 50mm either side of the damaged area.
As soon as the foil bandage packet is opened the bandage will start to cure. The Rapp-it Bandage has a work life of 4-5 minutes and a full cure time of 30 minutes. Rapp-it Steel Putty has a work life of 2-5 minutes and forms a tenacious bond within 10 minutes.
Yes. We supply the RAP304 (100mm x 9m) for larger diameter pipes and elbows. Multiple bandages may be required for very large pipes.
Yes, Rapp-it Pipe Repair Bandage can be used alone. We do recommend the combination of Rapp-it Steel Putty along with our Rapp-it Pipe Repair Bandage to ensure a more successful pipe repair.
Rapp-it can be removed with a hacksaw or angle grinder. Hammer and coal chisel is also an effective method of removing the bandage. When using an angle grinder, always use a respirator during the removal. Always check the fluid/gas in the pipe first as fluid or medium may be flammable. We advise the use of non-spark equipment and appropriate PPE when removing Rapp-it.
Rapp-it’s shelf life is approximately 2 years from date of manufacture, which is located on the exterior packaging. We recommend storing Rapp-it below 25°C (77°F) to ensure longevity.
Yes, however as Rapp-it is a temporary repair we recommend a job and location report be filed so the repair location is recorded for when a permanent repair is arranged at a later date.
Rapp-it is suitable for use on a wide variety of liquids, including potable water, diluted acids and fuels. Please refer to our Chemical Immersion Testing Results under the Rapp-it Certifications tab, for further information. We advise the use of acid resistant or chemset gloves for any kind of acid repairs.
