LET'S RESIN Silicone Mold Making Kit Liquid Silicone Rubber 140oz/1 Gallon Translucent Clear Mold Making Silicone-Mixing Ratio 1:1-Molding Silicone for Resin Molds,Silicone Molds Maker DIY Making

I got this to put on my dog's muzzle (he's not nice to my other dogs), so it would be more gentle on my windows, than just the metal muzzle. It took a bit of trial and error to see what would work-I was hoping to be able to dip it multiple times, but ended up having to set it in a form and then cut out the area in-between the bars . . . it turned out great!! Also, very easy to work with, and hardened quickly- 4 hrs or so!

I used this along with Let's Resin mold frame, with hot glue along the edges. Double sided sticky tape to hold objects down. I measured the product to1:1 ratio using my digital scale, stirred slowly in the same direction for 5 minutes (stopping to scrap my stick and sides of container a few times for a thorough mix) and added mica powder for fun at the end. Poured slowly into the mold, covered with foil and placed in the refrigerator for one hour. Afterward, I let in remain on my counter undisturbed til the following day.I had perfect results! I've done this 6 times now, each without any problems. I began making many sized saucers to place under my indoor plant pots. This allows me to add any fun colors or sparkle to display with my plants!

I have bought this brand several times and I do like this product. The cure time is about five minutes. The bubbles do disappear as the label says as the resin hardens it’s perfect for my molds, and the instructions are extremely clear and easy to follow

No real issues, somewhat delicate and molds don't last long, but for a couple dozen casts it works great.

Pretty beginner friendly. I mix in some mica to color the silicone to make sure it is well mixed and to make it pretty. It stays pretty liquidly during the working phase, great to pick up delicate details but will leak through the smallest of cracks in your mold casing. Feels pretty strong after it is cured. End product is quite firm but flexible.

My first ever mold pour ever. I didn't want to make the challenge too simple, so I used it to cast a mold of an ornate detailed frame corner of a 100 year old French mirror. Another corner had been smashed off (made of plaster) so I cast the cleanly prepared different corner and prayed. It was impossible to enclose the corner perfectly, I did my best. I poured the mix into my hopeful corner enclosure, and sure enough little rivulets of mix oozed out in about 6 places. I did the only thing I could do... for about an hour, I used a putty knife blade to gather the small puddles and return the mix to the top of my pour enclosure. I needed it for the full coverage of the high point. It finally started to thicken up so I stopped spooning and ran away, hoping I didn't ruin this customer antique restoration. Part of the pour was as deep as 2-1/2 inches so I gave the batch 3 days to fully cure. It took a while to coax the enclosure/solidified pour off of the mirror frame corner, but it finally released cleanly. Now I have to pour plaster mix into my new mold and hope again. I also hope I will be able to thoroughly clean the corner that was cast, because it is covered with residue of silicon, not a good base for paint. Bottom line, I would buy again.

This silicone makes mold making easy! The flexibility is great, easy release for items.

I wanted to replicate a mold that I already own. I wanted multiple copies of the same item so I can hopefully use them for candle making. I was definitely successful in creating a mold with this. The instructions were easy to follow. I filled my original mold with hot glue and made a bunch of copies of the cactus. I then built mold cavities. One out of legos from dollar tree and one from cookie cutters. I took contact paper and put it upside down and placed the mold walls on that and applied hot glue in order to hold it down and make sure there was no leakage. I measured on a scale part an and part b. There was a ton of bubbles and that made me really nervous! However in my finished product i barely saw any bubbles. I sat there and babysat this for at least a half hour blowing through a straw at any big bubbles I saw . I messed up on the bigger mold in my pics by not gluing down the items and instead trusting that dollar tree contact paper was strong enough to hold them down! A few of my cactuses floated to the surface and will now forever be entombed in silicone! I still got a few viable mold cavities.After the first half of the bottles were gone I decided to go ahead and try a second time. This time was a disaster! Once the bottle is half empty is is damn near impossible to get part B to come out of the bottle! The bottles are hard and don’t squeeze so you have to sit there waiting for it to slowly drip out! My scale turned off several times in the process which made things even more difficult! Part B should come in a tub or squeeze tube! Eventually I went into my garage and sawed off the top of the bottle so I could get a spatula in there and scrape it out! I even tried warming the bottles like you do with a baby bottle to get it to liquify more but that didn’t do much. It did help reduce some of the bubbles but it didn’t help part B move out of the bottle. I think possible storing the bottles upside down may help with getting the remaining few ounces out but I highly suggest they change the packaging somehow. Maybe put part b in a tub so that you can get it out easier. The more fussing you do with the stuff the more bubbles you introduce. The molds came out pretty good though and I even tried one with hot glue and it worked quite well. I would love to buy more and try more but not if they don’t somehow change the packaging. This is almost a waste because it’s so hard to get the remaining few ounces out of the bottle!UPDATE:I emailed let’s resin to ask them what I can do to get rid of the sticky residue that was left over on the top and bottom surface of the mold. At first they tried to insinuate I somehow didn’t measure and/or mix it properly and so I provided them with a video of me making my molds. Once they saw the video they then sent me an email telling me that it’s because I used “hot melt glue” as a master mold. They sent along part of their instructions where it does say that there could be potential curing issues with the “hot melt glue”. I don’t see how that is possible. The glue was fully cured and hardened for over 24 hours before I used it. In the instructions it says that the part that comes in contact with the “contaminate” may not cure properly. In my case, that is the ONLY part of the mold that actually cured properly! The mold functions properly. I’ve used it to cast already. It’s just the entire rest of the mold is tacky, causing hair and dust to stick to it.I would love one of their chemists to explain how cured hot glue will effect parts of the silicone mold that it didn’t even come in contact with such as the bottom, top and side surfaces of the mold! Sounds like a bunch of BS if you ask me and a company that just doesn’t want to take responsibility for perhaps a bad batch of silicone. I see other reviews here saying the same thing about the sticky residue and they did not use “hot melt glue” for their master mold. I mean right in the instructions that they sent to me and highlighted it says that the parts that come in contact with the substance that is supposedly a contaminate, is the part that wouldn’t cure right, so how is it that the rest of the mold is sticky? Makes no sense at all! They seem to be doing all they can to avoid having to replace items! I wasn’t even asking them for a replacement! I was just asking if there’s a way to get rid of the sticky residue! I emailed different resin company about an issue I had with their product and that time it was MY error and they replaced the bottles for me for free without me even asking! That’s a company that does right by their customers. This company is trying to avoid fault at all costs! Just be wary! If you ask questions they will do whatever they can to avoid blame and make it your fault, even if it doesn’t make sense!! As you can see in my photos, the casted part that actually came in contact with the cured “hot melt glue” came out perfectly fine. It is the entire rest of the mold that’s slightly tacky.
