I had a lot of fun make a mold out of silicone and then a temple out of resin. I added some silver acrylic paint to the resin to give it that sparkle.

    This stuff is my go-to for sure, and honestly, the Let's Resin brand seems to be quality no matter the product. As far as the mold making kit, it's great. Mixes easily, no bubbles, no chemical smell and a decent curing time. Some of my best molds were made with this, and I've used them numerous time with no change in quality or detail. Highly recommend to those starting with mold making, or even pros.

    this is the best size for the price honestly you get a LOT of use out of it. it dries faster than it says and dries very fast in the heat and humidity. never had bubbles, extremely easy to use and surprisingly easy to clean up (hasn’t ruined any surface). just make sure you mix thoroughly and don’t use the container you mix in to avoid any curing issues. if making pick pads, the thicker you make it the harder it is to pick from so it really lasts!

    The first time I used this brand of silicone, it cured perfectly fine. I like to keep at least 3 brands of silicone on hand just to make sure I have enough for orders and Lets Resin is one of them.

    During my most recent order of Lets Resin silicone, all the molds cured TACKY on the back. After the first failed pour, I did multiple pours using the same batch to test it out- some with less or no mica pigments/glitter, some with more pigment/glitter, etc. I also tried pouring in 3 separate rooms during different times of the day. ALL of the backs ended up TACKY no matter what I did, no matter how long I let the silicone cured. I did "touch tests" by poking the back at 8hrs, 12hrs, 18hrs, and a full 24+ hours. The backs never cured fully and remained tacky.

    If it was for personal use, I wouldnt mind although the molds would be annoying to move around and they would rip or break more quickly by constantly sticking to something.

    But I make & sell silicone molds for my small business. Tacky silicone molds are not professional or considered A grade to me. I had a large order to fulfill so I had to improvise with what I had and it was not fun.

    All my blanks are made from acrylic from my laser cutter. My biggest blanks are 5/8" deep/thick and 8" wide at most. My small blanks are 3/8" deep/thick and 4" wide at most. This batch of silicone did not work for any of these sizes.

    I will give Lets Resin silicone kit another chance but not anytime soon.

    4.0 out of 5 stars So easy to use, little to no bubbles. First time user!
    Reviewed in the United Kingdom on March 17, 2023
    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.

    Ich habe zum Testen zunächst die kleinste Variante gekauft ... und was soll ich sagen, ich bin schon ein bisschen begeistert. Die Verarbeitung ist kinderleicht (unbedingt die beigefügten Handschuhe nutzen). Man sollte sich definitiv an die Anleitung halten, welche gut verständlich geschrieben ist.
    Mit dem Ergebnis bin ich sehr zufrieden. Die Unzulänglichkeiten sind meiner Schusseligkeit zu schulden. Man sollte unbedingt darauf achten, dass die Werkstücke zu 100% plan stehen, um unnötige Nacharbeiten zu vermeiden.
    Einziges kleines Manko sind ein paar Luftblasen, die nicht, wie in der Anleitung stand, von selber verschwunden sind. Da sollte man auch drauf achten. Sonst ein top Ergebnis und meine Formen (allerdings recht klein) waren nach 5 Stunden perfekt.
    Definitiv Kaufempfehlung, ich werde das auf alle Fälle nochmal nutzen.
