ImPRESSive Re-Usable Putty


Product Description

Buy it Once...Re-Use it Over and Over Again!

Heat, PRESS onto your object, let cool, and you've made a mold!

Heat ImPRESSive putty until dough/clay like in the microwave. Once the Putty is cool enough to touch, create your mold by pressing an object into the putty. The Putty will become rubber like after only 15-30 minutes in the freezer. Create parts with polymer clay, epoxy, polyester, resin, clay, soap, candle, crayon, concrete and more. Make molds of sculptures, prototypes, candles, picture frames, coins, and more.

ReMold Putty Kit Re Meltable Re Usable Molding Putty 03:40

Heat •Place the Putty in an oven safe bag. •Add 2 drop of the Activator to the bag for every oz. of Putty. •Seal the bag with an oven safe plastic tie. •Heat the Putty in the microwave until completely melted (see estimated microwave times below). Caution!! IT IS VERY HOT. Microwave times (estimates-times will vary) 3oz. 10 second intervals until melted 6oz. 15 second intervals until melted 16oz. 30 second intervals until melted You can also melt in a double boiler. Let the Putty cool to a temperature comfortable to the touch before removing from the bag (115 deg or less.) Duplicate To make molds, Smooth the putty to remove lines and make into a shape large enough to hold your master object. If you are planning on moving your mold before it solidifies place it on a plate. Next push the Re-Usable molding putty over your master part or push the master part into the putty and when necessary apply a Mold Release Release compound is typically not necessary. Let the Re-Usable molding putty solidify. The master object is ready to be removed from the mold when the putty does not deformed when pressed with your finger. At room temp leave the mold overnight. (Optional) move your mold to the freezer to solidify faster. Wait 1 hour before DE molding the object. Remove the master part from the Re-Usable molding putty, apply a Mold Release if / when necessary to the mold, and pour or press in your casting material. Reuse With the Re-Usable molding putty, many casts can be made with the same mold including wax, and plastic casts. When you finish making duplicate parts, reuse the Re-Usable molding putty to make more molds and cast parts. The unique aspect of Re-Usable molding putty is that it can be continuously remelted and reused to make new, unique molds. Mold Making Tips •Spray porous objects such as wood and cloth with water. Water helps pull the putty into highly detailed areas of the object. Once the putty touches the damp porous surface do not attempt to remove it until completely solidified. •Do not add water to smooth objects, putty will move and it may create cracks. •Wait for the putty to cool to about 80 Fahrenheit before molding, at higher temps it will slowly droop losing its shape. In some situations were drooping may be beneficial use it at higher temps. (Be careful of burns) •Smooth the putty surface before attempting to create a mold to avoid creating unwanted lines. •Wash and thoroughly dry your hands before shaping to prevent sticking to hands. •The Putty can be carved and sculpted - When molding a sculpture or carving that was created from the Reusable putty, coat it with a mold release such as cooking oil or other safe mold releases. •Molds will last as long as they are kept out of direct sun and high temps. Important note The activator is important for solidifying the mold and useful as a built in mold release, but it will slowly leak out of the mold over time. Too much activator on the mold surface is undesirable, remove the excess and pools of the activator with a sponge or dry cloth before pouring your casting resin.

  1. Short Learning Curve, Now Works Well 5 Star Review

    Posted by on 13th Oct 2016

    I bought this for a specific project: I am making a polymer clay custom "skin" for a powder compact, and wanted a silicone model of the top of the compact upon which to work and fire. I knew it was going to be a challenge - the compact is super-smooth plastic, making air bubbles a distinct issue, and there is a narrow groove into which the skin fits, also a challenge. The easiest way would have been to pour the first mold in silicone, then pour again into that mold, but that's a lot of wasted silicone, and expensive. It also would have been very exacting to build a clay dam to isolate just the compact top for a silicone pour. I found that any issues I mention below are mostly "user error" - IRP is a very good tool to add to one's kit.

    Using IRP, I was able to press just the compact top into it, without having to build a dam of any sort. It took 2 tries - I didn't smooth the IRP as well as I should have, so the creases left traces/bubbles in the master pour. I had expected that pressing the compact into the IRP would smooth those out as it would in silicone. I also then smoothed the IRP over the edge of the top, to create a lip so that, when I poured the master, I would be able to fill up the mold and get a smooth bottom. I had a rather thin layer of IRP for the lip, and some of it crumbled off when I removed the compact. When next I use IRP, I will just be sure to have enough thickness for every part of the mold.

    On my first try, I wiped out the excess activator as directed. However, I poured a resin master during that attempt (cheaper than silicone when experimenting), and it came out extremely bubbled. I believe that is due to activator continuing to leach during the cure. The IRP came with a decided "slimy" feel - I realized that I should NOT have added activator for the first use - it already had plenty. On the second try, I added NO activator, and notice much less activator leaching, and the silicone master came out great.

    the bag is a great idea - you can knead the IRP after microwaving, then open to pull out as much as you need. However, I wish the kit came in a container with a lid, instead of the hinged plastic pack - there is no way I can get the finished mold (once done with it) back into the package without having to re-microwave all the IRP, so I end up with the various components sitting all over my work bench. It's not a big deal - I will find a different container - but it would be nice to have a branded container in my storage area.

    I would like to know if there is a IRP-to-IRP release agent I can use that won't corrupt the IRP. IRP would be great for experimenting with 2-part molds before pouring the final one in silicone.

    I am VERY glad that I finally broke down and bought IRP - it is much easier in certain applications than using ComposiMold, as sometimes one needs a putty, not a pour!

    It's hot right after I take it out of the microwave, but cools quickly. It is really easy to use. I pressed it over a rubber stamp. Worked really well.

    Unlike silicone putty, I can re-melt it over and over again. Works really well for fast mold making.
