Can someone tell me how to compensate for low humidity when using Monster Makers' foam latex? As I'm reading online, all I can see is that if you're in a high humidity environment, to use less gelling agent (if I'm remembering the instruction correctly). The instructions from Monster Makers indicate they're assuming a 50% humidity level. I'm in northern Nevada, where today the humidity is 9%, which is pretty typical for this area.
All the info I've found says that humidity has to be taken into account, especially with the gelling agent, but I can't find anything that tells me exactly how to compensate for the really low humidity I work/live in. I've had some trouble with the foam collapsing, and while I'm not 100% sure that humidity is the issue, I figured I'd start there. Thanks.
Foam is a black art. Here in southeast Michigan the humidity ranges from 30 in winter to yougottabekiddingme in summer. I always use slightly less than recommended.
If you have enough kit materials, you might whip up a test batch. Divide it into 2 to 4 parts just before you add gel, then add different gel amounts separately to each partial batch and see how fast each sets up. This will only be a rough estimate based on how accurately you can cut a batch into smaller parts plus how accurate you are at measuring gel amounts of 5 grams or less. But it might give you some clues.
Thanks, Dave, I appreciate the suggestion. That's a great idea to divide it. I did discover that our thin air does require me to whip it longer. Fortunately I bought an inexpensive gram scale at Harbor Freight which seems to work great in measuring. Thanks again.
