Hey folks:
I need some confirmation on a problem that I'm having with rock castings. This AM, I began making cast rocks for the South Ridge area on my layout. I mixed up 1 cup of water, 1 cup latex paint and 2 cups of Hydrocal. I sprayed the insides of the molds with "wet" water and poured in the plaster. That was at 10 AM. It is now 4:00 PM and I just flushed out the last mold. The stuff NEVER set. It was as wet when it came out as it was when it went in!!!
My conclusion is that the Hydrocal was TOOOO old. I bought it at the train shop in Spencer, NC and I know that I haven't been in that place for 3-4 years.
Let me know if you think something else could be the problem.
Thanks
JR
