Hi all, I apologize in advance if this has been answered somewhere else but I could not find an answer.
I am using the amazing mold putty - the type that comes in 2 tubes, one yellow, one white. I follow the instructions by mixing equal amounts, rolling it over the item to be molded, curing for 20+ minutes. I am using this with handmade polymer clay pieces.
The issue I am having is that when I remove the clay item, there is yellow residue stuck to it and the resulting texture of the mold is not smooth. When I use the mold and remove the clay after baking, the finished piece has a rough texture from the mold not being smooth.
Am I doing something wrong? Not curing for longer enough? I'm rather frustrated because the putty was rather expensive (for me) and I have had no success yet. Any advice is welcome!

Sounds like their is inhibition of the putty to what you are pressing it over. Inhibition is a type of poison that affects the putty only where it comes into contact with the inhibitor. So the putty cures perfectly everywhere other than where it comes in contact wit a material that does not allow the surface to cure. Common inhibitors are tin, sulfur, vinyl, amines, and super glues. If the polymer clay you are using contains any of the chemicals, it will cause the surface of your mold putty to not cure ... which you are describing as a yellow residue.
Perhaps, try smearing a very thin layer of Vaseline over the master prior to applying the putty and test a small area to see if this protects the putty from the inhibition. The other way which will definitely work is to use the Amazing Mold Rubber which is a tin base silicone rubber that does not inhibit when it comes in contact with any specific materials. Then you will have a perfect mold of your polymer clay piece that you can use for a push mold for polymer, resin, plaster, or anything else (other than food as it is not FDA compliant like the Amazing Mold Putty).
Quick question ... was the polymer you pressed the putty over baked?
thx,
Mike

Hi mike, thanks for your answer. Yes, the clay pieces are baked. I think that letting the putty cure for ~30 minutes has made a difference. I will also try with Vaseline. Thank you!

I have experienced this problem, too, on multiple materials...natural elements like a pine cone, wood, rubber, plastic, and more. I know my measurements have been very precise since I use a cap from a deodorant stick, of all things, but it act like a scoop. But when I took a workshop where I first worked with this putty, I had no problems. I thought it was perhaps my house was too humid. Or could it be the cap/scoop I'm using to measure out the clay? I wonder...

I wonder... Update! I used another plastic spoon this time to measure equal portions of the ingredients and I noticed right away as I was blending the two that it was less sticky and could actually see the colors coming together. I molded my item and left it under a lamp (normal house lamp since I don't own a heat lamp) and after about 30 mins I was able to see the sides ready to pull away from the original and pull it totally off. I still have some residue stuck on the mold from the acorn itself but nothing a good toothbrush or paintbrush can't handle. Or I may use some scrap clay to get it out. But I am happy to find out it's working, finally! Before with my other measuring tool the ingredients almost immediately turned yellow but remained tacky and even gooey until I could finally separate the putty from the original the next day. One last tip: I removed the yellow and white ingredients out of those tall containers into their own separate shorter square ziplock containers and that makes removal for later blending so much easier! Learned that from clay artist, Mari O'Dell. |

Do you have any tips for removing the Amazing Putty residue when it does not cure by being 'inhibited' on a rubber stamp? I am happy to find out what went wrong with the rubber stamp...but am having problems cleaning up the mess.
Thank you!

Susan,
Of course pull of what you can with a paper towel. Then using a soft bristled old tooth brush, along with good old rubbing alcohol is the best way to get it off. I don't think the alcohol will be any issue for the rubber stamp, but test is best first.
Have a wonderful day.
Regards,
Carol
