Hi,
Using milliput standard, the yellow one, and I was wondering if there is any method to make it dry kicker. It generally takes around 3 hours to completely dry.
Since its a 2 part putty I understand that it hardens due to a chemical reaction, thus little can be done to easely accelerate it without ruining either the model.
Any hidden tricks?

Hairdryers or other fans are usually the tool for cutting down on drying times in the hobby.

Leaving it in a warm area might help it to harden a little faster (heat often assists reactions to happen faster. Resins "go off" faster in warmer weather, for example. Their "pot life" is reduced).

Like sitting it on a window sill in the sun?

Makes sense, I'll give that a try. Now in winter heaters that are on anyway might do the trick. I'll run a couple experiments and share if there are any significant differences.

I use an incandescent lamp to speed up the curing of resin putties. They might be inefficient for producing light, but they're great at warming stuff up.

Just be aware that it might soften initially as it warms up making you think it's actually slowing the curing, but the overall cure time should be reduced, and don't accidentally melt the rest of your model (yes, I've done this before ).

Milliput doesn't dry, it cures.
The chemical reaction is heat dependent, so increasing the temperature (reasonably! like a lamp or hair dryer) will make it set faster.

Conversely putting it in the freezer slows the reaction down. Freshly mixed Milliput can last multiple days if frozen and still be workable.

If your oven has a low temperature setting (ours can run at 35 degrees for proving dough), you could try that but I’ve never given it a go.
