Failed Rebound 25 Mold

[Jason Gray]

I recently tried making a silicone mold with Rebound 25 and made an error at some point and the silicone will not cure.....is there any way to remove the silicone while salvaging the sculpture underneath

Links to any products would be awesome as well

Not sure about cleaning it, but did you wear latex gloves? Latex causes cure problems with siicons

Isopropanol is good for cleaning off uncured silicone. What is the sculpture made from? I clean brushes used to apply silicon with is to. I get mine on Ebay.

Dericrw I either messed up the ratio mixing or added too much thickener.....I had vinyl gloves on

Alaneye I am using Chavant NSP Hard Clay

I have ruined molds with too much thicker and it ruins curing.

I have tried to same the molds, but usually starting over yields the best results especially if you are going to make a lot of pulls. It is no fun fighting a bad mold over and over.

I plan to make multiple pulls

and of course I would mess up my first mold lol

but its all good and I will keep at it I just want to save what I can of the sculpt...but if I cant I'm willing to start over but will still need to find a way to cleanly remove the silicone

I used a cotton rag and 93% Isopropyl Alcohol and scrubbed down the surface....while it did cause some damage to the sculpt I was able to fix it without any problem....I dare say it looks almost better then before!!

AWESOME! Can't beat that scenario.

Well.....after looking at the pictures it still needs a little TLC but all and all its still a win in my eyes.......will attempt molding again soon....Wish me luck lol

Jason,
Do yourself a couple of things:
1. put some silicone over a small section of the clay to make sure there is no contamination from the clay factory... though it doesn't happen to often, it does sometimes happen... they make sulfur and non-sulfur clays in the same building....
2. Don't put thickener in the first two coats of the Rebound!!!! Let them cure before adding a third and fourth thickened coats... (as mentioned, watch the amount you add)
3. Seal the clay with some Krylon Crystal Clear.. might make your life easier in the long run!

Will do....I just ordered some more Rebound 25 and will be trying all that you mentioned....thanks for the advice

 

[Jason Gray]

after extensive testing i realized my clay was the issue....so i rigged up a setup to try out oomoo 30.....all should go well

 

[Beaker]

OOMOO I don't think is the right silicone for this.... first it isn't a brush-on, second, the tear strength isn't the greatest....

 

[STEALTH]

I think he's using Oomoo 30 to test the clay to see if it was the issue.

Its been awhile since I gave my last update.....so heres my first ever casting of Deathstroke





I will be sculpting a new version soon to make it more accurate with possibly a Black Mask helmet to follow
