northsea Posted October 25, 2008 Report Share Posted October 25, 2008 Hi there, Here's another question from a complete novice. Is there any preference as to when you do a few finishing touches to you plaster mold? (Perhaps scrape away a little excess plaster round some edges) Is it best to do this immediately after making the mold or after it has had time to dry out properly? Any help would be brilliant.

njrfishing Posted October 25, 2008 Report Share Posted October 25, 2008 I've only made a few plaster molds and I do the sanding or finishing touches when the mold is completely cured and harden because I find it's too brittle and easer for the plaster to break when it's not completely cured.

nova Posted October 25, 2008 Report Share Posted October 25, 2008 If you do your repairs/changes to the mold before it dries and make mistakes you can still repair it with water and a little rubbing; or even some fresh pop mix. After it cures the repairs will be a lot harder to do(if not impossible). www.novalures.com Quote Link to comment Share on other sites More sharing options...
northsea Posted October 25, 2008 Author Report Share Posted October 25, 2008 So if I need to do repairs do it immediately after making the mold and if everything is ok but it needs a little sanding do it after it has cured. Is this the basic rule of thumb? Quote Link to comment Share on other sites More sharing options...

GB GONE Posted October 28, 2008 Report Share Posted October 28, 2008 I do my repair work before the molds are dry. If I am adding any appendages, dimples, etc, I will add those after the mold is completely cured. Dremel type tool works great on pop!
