Steel filled epoxy putty for sealing cracks, filling holes and carrying out repairs to pipes and structures made from steel, iron and other ferrous metals


Superfast Steel Epoxy Putty Stick is a steel-filled epoxy putty used to make fast-setting repairs to steel, iron and other ferrous metals.

It is used to seal cracks and holes in steel and iron pipes and other metal applications as well as filling in damage caused by pitting and corrosion. Superfast Steel Epoxy Putty is resistant to water, chemicals and temperature extremes and has WRAS approval, which means it is safe to use with drinking water.

Superfast Steel can also be used to bond metals and other materials together. Within an hour of applying Superfast Steel, systems can be put back into full use.

How to repair steel and iron using a Superfast Steel Epoxy Putty Stick

Superfast Steel comes in a pre-formatted 114g stick. To use, you simply cut off the required amount of putty from the stick and knead it by hand.

Whilst soft, the putty is pushed into holes and cracks in steel and iron where it will fill the hole and set rock hard. Superfast Steel has a work life of approximately 3 minutes and within 5-10 minutes, it will harden and form a cohesive bond. A full repair is completed in one hour.

Superfast Steel contains no solvents or VOC’s, it is non-flammable and releases no noxious fumes. It will not shrink or pull away and the unused portion of Steel Stick stays fresh for future use when saved in its original package.

Repairs made with Superfast Steel Stick can be overwrapped with SylWrap Bandage for a fast, permanent, high-pressure repair. Superfast Steel and SylWrap Pipe Repair Bandage can be purchased together as part of the Standard Pipe Repair Kit which enables the user to permanently fix a leaking copper pipe.

Please note that for fixing a steel or iron pipe, Superfast Steel Epoxy Putty Stick is only effective when water pressure can be turned off. For carrying out live leak pipe repairs, please see Wrap & Seal Waterproof Pipe Repair Tape.

For repairs to pipes and metalwork which is subjected to temperatures in excess of 200°C, please see our Superfast Titanium High Temperature Epoxy Putty Stick which has been specifically designed for extreme heat applications.
