At 4 lb, Silver-Grey is intended for workshop-scale sculpting, mould filling, armature builds and repeat work where dependable quantities across successive batches matter. Its two 2 lb tubs keep the components separate while each section of a larger job is prepared. Once mixed, the compound provides a 1–3-hour working span for forming and refining the surface, and dipping tools or fingertips in cold water keeps it from clinging while that detail is worked in.
Combine equal portions of Parts A and B at 50/50, then knead for two minutes to activate them fully.
The material self-hardens without an oven and completes its cure after 24 hours.
Delay sanding or drilling until that full cure has been reached.
The maker specifies a hard, waterproof result and 0% shrinkage.
A five-minute pause after mixing improves the handling character before work continues.

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.
