Sylmasta Superfast Steel Original is a versatile, self-contained repair kit designed to meet the demands of maintenance professionals in the field or on the plant floor. Each kit is packaged in a sturdy, transportable case containing multiple Superfast Steel epoxy putty sticks, making it easy to keep essential repair materials organized and ready when needed. The putty sticks are individually wrapped and pre-formulated with resin and hardener distributed throughout the stick — no measuring, no tools, and no mess.
The epoxy compound is engineered for fast, reliable repairs on metal surfaces and compatible with wood, glass, masonry, and many plastics. Once mixed by hand, it begins to harden within 5 to 10 minutes, allowing quick return to service. Full cure is achieved in one hour, at which point the material can be drilled, tapped, machined, painted, or sanded. Whether it’s a leaking pipe, damaged bracket, worn thread, or small surface crack, Superfast Steel provides a permanent, industrial-strength solution that minimizes downtime and maximizes efficiency.

What temperatures can it withstand?
Continuous exposure up to 250°F (120°C), with short-term exposure up to 300°F (150°C).
How many repairs can one kit handle?
That depends on the size of each repair. Each stick is 7 inches long (175mm) and weighs 4 oz (114g).
Will it bond to non-metal surfaces like wood or plastic?
Yes. It’s designed to adhere to a range of substrates including wood, masonry, and many rigid plastics.
