Hello, I am new to the world of silicone mold casting, but I see great things for my future! Last night I successfully created my first piece from clay, baked it and made my first mold with the box kit of high strength liquid mold making rubber and small bottle of catalyst from my local craft store. I learned so much with what I was doing that I want to try again! But now the measuring cups are all sticky and water won't touch the stuff for me get the cups clean. I have looked on all my inserts, box, online and have found nothing that speaks of cleaning the measuring cups. I'm not serious enough yet to have the scale or multiple cups to measure with and I learned that you need to be exact. Any help in this direction would be helpful.
With the RTV Silicone, you can remove excess from the cup by simply peeling it off of the cup once it has cured with out any noted weight gain on the scale....I use a Red Solo cup several times before the bottom starts to get soft from the Silicone. With the catalyst, wipe out as much as you can with a paper towel. I reuse the catalyst cup ( for me its a small plastic bathroom cup) a few times, with out cleaning, before it builds up enough to show any weight gain on the gram scale....and by that time I toss it out and get another. Once you get some confidence under your belt, the sky is the limit as far as what you will be able to accomplish....so jump on and enjoy the flight.
You should see the things I use as cups and dippers with what I do. And I'll use them until they get past the wiping out stage even though I wipe them out every time I put everything up. When wiping with a paper towel doesn't work, you can use a Wet Wipe or a degreasing wipe just be sure to use water to rinse after using those two. Hand Sanitizer works to clean your hands of anything that gets under your gloves or on any tools but you have to be sure to rinse them off as it WILL break down and mess up anything made with them. Feel free to ask any questions you have, we don't mind sharing and helping
Thank you both so much! I will try both of these methods. I am very encouraged from my weekend projects and my son is too! He came to me Sunday afternoon and has stated he wants to try and make a guitar mold! Sky's the limit huh?!?!
