The 1 lb Silver-Grey kit is a regular working format for modelmaking, seam filling, prototypes and restoration without moving up to workshop-scale tubs. Two 8 oz jars hold the separate components until a measured batch is needed. The mixed putty stays workable for 1–3 hours and then self-hardens without any baking stage, and a wet finger, brush or cotton bud will smooth or texture the surface before it sets.
Take equal amounts of A and B for a 50/50 mix and knead continuously for two minutes to activate the compound.
Allow 24 hours for complete curing before the piece is sanded or drilled.
Aves describes the final state as hard and waterproof and claims 0% shrinkage.
Leaving the mixture to rest for five minutes can improve control during later shaping.

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.
