  • Good quality
Size: 8OZ
This mix is easy to prepare and doesn’t take too long to solidify. I’ve bought it a couple of times for small craft projects and it’s worked very well!

  • My favorite brand.. works everytime
Size: 64OZ
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. ... show more

  • VS. Other methods
Size: 8OZ
The media could not be loaded. Fast cure time on a 80+ degree summer day. I think that also helped the bubbles escape to the top faster Retained detail. My go-to material for a very quick cure but still capturing detail is alginate. (Used for dental molds) However, the life span is very short and will dry out and eventually shrink- even faster if not wrapped in a wet towel. Alginate does not have the same viscosity and I wouldn't consider it for a pour but after cure it may have a little more flexibility to release without damage. I also wanted the reusability of a silicone mold. One thing to really consider when mold making is sometimes you will have to make a 2 or 3 + part mold. My small scale project had intricate contours, convex, and concave sections that made it harder to pull out. Given the somewhat flexibility of silicone, I still ended up cutting it into 3 parts which was how the original metal was casted. I was worried about resin leaking through the seams but I had no choice. Tried it and leakage was minimal. I was able to scape off the less than paper thin seams that did seep minimally. I did use a rubber band for security. For my tiny stand reproduction, the amount was just enough. I used almost the entire bottle even with finding the smallest cardboard lid for minimal waste and I lined it with smooth packing tape. I have experience making molds with different types of plasters, cements, latex, etc. and an intricate design is a guarantee that you will have to make a divided mold requiring more effort and additional materials. I will still keep that tradition with large scale projects because I don't think anyone would find silicone to be cost effective for anything larger! But... for my first time, this small scale project turned out successful enough to use! ... show more

  • Make sure prep work is done before mixing!
Size: 64OZ
I wanted to copy a statue for my garden and couldn't believe how easy this was to use! (But a little messy) Make sure you have the container ready and item (like a little statue) secured down when you pour the silicone in or it will float up and make a huge mess. It hardened within hours and my little statues came out perfectly. Didnt even have to mix as long as they recommended, and now the mold is very sturdy yet flexible, easy to get finished product out. Even parts where it was a little thin because of my placement are strong and no tears or rips at all. Great Product. ... show more

  • Works well but sticky
Size: 8OZ
I measured out a 50/50 mixture by weight per in instructions. Maybe I just got the wrong type of silicone but even after a week the finished product was slightly sticky and would leave a fingerprint mark if touched. Still did what I needed it to do but a better description from a novice silicone user might be helpful ... show more

  • My Go-To for home made picking pads
Size: 64OZ
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! ... show more

  • Makes a good mold!
Size: 8OZ
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!<< ... show more
