Amazing Mold Putty Review

Amazing Mold Putty

Amazing Mold Putty, a fast, inexpensive way to make a mold.

Yarr, the crafty SalemPirates are always on the lookout for new and nefarious techniques to add to our bag of tricks. Recently, Capt. Bill heard tell of a new product, Amazing Mold Putty, so we decided to give it a test in the infamous Pirate Labs.

The product page has this to say...

"Amazing Mold Putty is the easiest and safest way to create exact cast replicas of practically anything in minutes! FDA compliant, great for making quick simple flexible rubber molds for resin, plaster, polymer clay, wax, chocolate, soap, and much more."

Prepping the Master

The SalemPirates have had some experience making molds and we applied that knowledge to our test. For our master we used a charm of a sailing ship that we plan on using as a geocache travel bug. We used the clear plastic lid of a CD case as a base for our master.

We used a bit of clay, rolled extremely thin, to adhere the master to the plastic. This keeps it from moving around while applying putty.

Preparing the Putty

The master is prepped and the "meatballs" are ready to be combined.

The directions on the box stated to mix equal amounts of the white and yellow putty together. We pirates used the time tested "meatball" rolling method to gauge when the amounts were equal. There are other mold compounds that require the use of a scale but that wasn't the case here, the Mark-1 Eyeball method worked fine.

After measuring out the amounts of putty, it was time to squish the meatballs together. From our previous experiments, we know that once this happens the clock is running so make sure you're ready with your master. Also, mix well and mix deep. An uneven mix can cause pockets where the putty does not "rubberize".

Applying the Putty

Squish the putty against the sides of the master to ensure a tight seal.

Once the putty is mixed, it's time to apply it to your master. We had heard reports that during this process the putty would move away from the lower edges of the master.

Arrrggg, but we pirates are indeed a crafty bunch and we were ready for this!

We placed the master on a clear CD cover for a reason. During the application of the putty you can flip the cover upside down and ensure that the putty is tight against your master. Just squish it in the direction needed to ensure a tight mold.

Once we had a good, tight fit around our master, we then leveled the back of the putty using another CD cover. This will let the finished mold lie flat when you are pouring your material into the mold. Avast! Don't push down on the putty too hard! You don't want to squish it down so much that you meet the master.

Pirates hate waiting...

Capt. Bill's previous mold making experience requires 12 to 24 hours for the mold to set. Sure it's a higher quality mold. Fine, it will last longer. But there's only so much grog in the fridge and he wants to make copies!

In this case though, the mold was fully set in 30 minutes. The instructions say 20-25 minutes but pirates trust no one.

After allowing the mold to set, it easily came off the master. There was only one test left, making copies!

Test Results

The master and its copy, a very nice result.

For our test, we used a dental plaster called Excaliber. We're not going to get into all the details on this product here, but just think of it as plaster of paris but 20 times harder. It's the stuff dentists use to make reproductions of your teeth.

We mixed up some Excaliber and poured it into the mold. Dental plasters have a set time so we waited about 15 minutes. Then we scraped off the back of the mold using a putty knife. This makes a smooth back surface and gets rid of the excess material.

After we allowed the plaster to dry, we removed it from the mold. We lost the loop and the very top flag, but Capt. Bill was in a hurry and might not have allowed the plaster to fully set. Plus, those items were very tiny and the master wasn't very thick, so we weren't disappointed. This was just a test afterall, matey.

After that, we spray painted the copy silver, applied a spray gloss sealant and a black ink wash.

Final Thoughts

We were very happy with the results of this product. Sure, if you want a more detailed mold, a 2 part liquid molding compound is better. But for a quick, inexpensive solution, Amazing Mold Putty works great.

We bought this product at Michaels, a national arts and crafts chain with stores in the Salem, OR area. It retails for $20 but Michaels frequently has 50% off coupons in the Sunday paper bringing the price down to $10. Not a bad deal at all!
