Anyone use this stuff?
I’m getting good results making rock molds with it, but the old soaked-paper-towel hardshell method’s not going as well: when dry, it seems to be weak and flakes off.
Ideas?
I used it a number of years ago with good results.
Do you remember the ratio of water to Ultracal you used and/or how you measured it?
No, I don’t. Sorry.
I recall using it just like hydrocal and having to play with the ratio to get the best for my scenery.
