Kneadatite Blue/Yellow is the original “Green Stuff” sculpting tape: a springy, non-grainy two-part putty for modelling, conversion work and fine detail. Cut equal lengths of the blue and yellow strips, knead them to a uniform green and use damp fingers to make mixing and shaping easier. At 24 °C it provides 1.5–2 hours of work life. The cured material holds folds, edges and small surface detail, then becomes workable with saws, drills, carving tools, abrasives and paint.
Choose from cut tape lengths of 6, 9, 12, 18 or 36 inches.
Functional cure occurs after 4–5 hours, when the material can be drilled, carved, sawn, sanded and painted.
Ultimate hardness is reached after 20–24 hours.
The tape has a minimum shelf life of one year in its original unopened packaging at 24 °C.
It will not adhere to polyethylene, polypropylene or PTFE.
Polymeric Systems states that it is not intended for structural applications.

Notes · Q & A
What's the difference between Green Stuff and Milliput-type putties?+
Green Stuff is flexible and springy, holding fine sculpted detail like cloth and cabling. Milliput-type putties are harder-setting and sand smooth once cured, which makes them better for gap-filling and surfaces you want to blend flat. Many sculptors mix the two.
How do I stop epoxy putty sticking to my tools and fingers?+
Keep a little water on the tool and your fingertips as a release; the putty won't grab a wet surface. Work in good light and let very tacky putty firm up for a few minutes before shaping fine detail.
How do I get the mixing ratio right?+
Most epoxy putties cure at a 1:1 mix of the two parts by volume, kneaded until the colour is fully even with no streaks. Under-mixing leaves soft patches that never fully harden, so mix longer than feels necessary.
How do I fill a seam gap cleanly without losing nearby detail?+
Press a small amount of putty into the gap, then wipe the excess back with a wet tool or a cotton bud before it cures, leaving putty only in the recess. Cleaning up wet saves sanding over detail later.
