LET'S RESIN 8oz Silicone Mold Making Kit, Fast Cure Liquid Silicone Rubber

What a great product this is! I had never used silicone rubber to make moulds, so I decided to get the smallest kit to try it out. The amount of detail you get is awesome. The key is to mix it according to the instructions and measure it by weight rather than volume. I use a very accurate small jeweller's scale, and my measurements have been on point. As a container for the mould, I have used a very small container that I line with packing tape, that way I can reuse the container, and pulling the tape helps me take the mould out, easily, without damaging the base. One of my favourite characteristics is that it is self-degassing, which means that if used correctly you will not have any bubbles in your final mould. The outcome is a very detailed, flexible, yet sturdy mould. And I will repeat this because I know how people like to skip reading instructions, but unless you read and follow them with accuracy, your results may not be what you desired. If you want to try the product with a small sample -like me- this size of compound will be plenty, but do consider a larger option for other uses. I really recommend the Let's Resin Silicone Rubber!

These are incredible!! Easy to use, sets fast and leaves absolutely no bubbles on its own.

I like this silicone mold making kit. The mold is very durable, good texture, bubble- free, easy to clean.

Making my first mold in YEARS, and this stuff worked great! Picked up all the details, no bubbles on the surface or on the mold surface, and released the master and casts easily. It is also tough and tear resistant and my mold feels durable and like it will last. It was a great experience to use and the results are all I could ask for and more! Just be very, very sure your mold box is of appropriate material and is absolutely and totally sealed. This silicone is low viscosity and WILL find any holes in your box and leak out (ask me how I know lol).

Even though I knew I would need the full mixed amount I still weighed it on my scales. The label said 115g per bottle. All I could get out of the each bottle was 108g. There's no way there was still 7grams left in each bottle. Other than that it set up nicely even though I didn't have quite enough to cover my master.

I figured to make a few trial pours with this sample kit, but the 8 x 8 inch piece I wanted to mold took nearly ALL of both bottles. This is OK, since I bought a MUCH larger kit (about 10x) of the same stuff! >>First off, measuring with a super-accurate scale was really important, since the parts A & B are equal parts by WEIGHT (and I was impressed by How Much More part B was by weight than part A.) >>(Equal parts by Volume won't work- it ends up being a sticky mess that never cures properly!)<< >I mixed 2 times A & B for this same mold having underestimated how much I needed, but the Silicone material allowed this (it was within 10 minutes for the second mix.) >Leveling of the mold was important since it's a FLAT texture that should make for some interesting effects. >After 4 hours the Silicone has solidified but I'm going to wait for about 10 hours to make sure. >Previous attempts with other casting compounds haven't worked BECAUSE: -(1)- Not proper proportions to begin with. -(2)- Not stirred enough to completely mix A & B. -(3)- Mold not level. -(4)- NO Mold Release used and the Silicone stuck to the molded surface and tore! >One of those small "Bulls Eye Bubble Levels" was used to get the mold LEVEL and I used some thin wedges to push under the mold to get that BUBBLE IN THE CENTER before anything else. >I mixed each A & B for at least 5 minutes with the flat spatula furnished in the kit (much better than a thin stick.) >I sprayed mold release -SELSIL- (Take Precautions!) on the surface YESTERDAY to give it lots of time to dry. Looking down through the clear smooth surface of the CURED Silicone there are NO bubbles or parts that are not fully formed on the mold surface. >I Read the INSTRUCTIONS, used a scale that made this all exact, and did everything in advance to make this try a Success. Altogether it took several days of preparation for one small mold, not including how long it took to carve the piece I molded. >>Take Your Time!<<

Takes a long time to cure, but it is super simple to use, instructions were clear enough.

This is a great kit for a first timer like me. It has 2 measuring cups, gloves and 2 popsicle stick stirrers. Loved that it came with those things as I didn’t have most of those on hand. You mix bottle A and bottle B at a 1:1 ratio with a minimum of the combined mixture being no less than 30 grams. I read it wrong and thought it was 30ml so don’t do what I did as I could have used much less from each bottle if I weighed it instead. Since I didn’t use a lot or have a mixing cup, I poured one of them into the other measuring cup and then mixed for 3-5 min. You then pour the mixture into the container (not made of silicone) you have ready to hold the mold. Make sure what you use is flat because it won’t cast well if it’s curved like mine was. Newbie mistake. Lol. Amazon sells flat ones specific for making molds that I’ll purchase if I decide to do more.

Easy 1:1 measuring ratio. And a very durable final product. Casts so detailed i sanded the Master Form and all the cast pieces were ready for paint immediately.

First time working with anything like this and it was very easy to work with

Works great

This product was so easy to use, this coming from someone who has never used similar products before. I had no issues at all. Bubbles if any, were small and few but did not affect the mold. I took away one star because clean up was horrendous. I followed instructions of using warm water and soap and that created a huge sticky oily mess much like Vaseline that i just couldn't get rid of. I had to use acetone to undo what warm water and soap did. I later found out, just wiping the stuff off with toilet/kitchen roll (tougher paper) paper worked. I finished off with just running my tools under water and wiping it dry.

Un peu compliqué à manipuler, il faut un peu de pratique pour obtenir des moules corrects (les vidéos de tutos sur YouTube aident beaucoup) mais après on peut reproduire plein de petits objets dans les détails. Il faut prendre des contenants bien étanches car sinon le produit a tendance à fuir partout. Séchage ok et pas de bulles. Assez onéreux au regard de la quantité. On ne peut pas faire de trop gros moules. J’en ai déjà commandé 2x et le recommanderai encore car c’est sympa comme activité et ça marche très bien avec la résine de la même marque.
