Silicone Mold Making Kit - 1 Gallon Liquid Silicone Rubber 15A with Adjustable Mold Housing - Fast Cured Easy 1:1 Mixing Ratio Silicone Casting for Making DIY Silicone Resin Molds - with Instructions

The media could not be loaded. Curing shouldn't take as long as some reviews complain about. Either they had a bad batch, added too much pigment, or didn't mix it completely.Mix it until there is only one green color. No streaks of white. No spots of light or dark green. Mix it for a couple minutes like the instructions tell you and you'll have no complaints.I only used it for the 75ml cube in the photo and I'm sure larger batches will require longer mixing. You'll have over an hour before it shows any signs of setting so you'll have enough time.After properly curing, there were no bubbles or wet spots throughout the cube. There was a tacky feeling like new rubber or silicone as you'd expect. As you handle it, the silicone mold will pick up dirt and oils from your hands and lose its stickiness like tape does. If you want to get rid of the feeling faster, throw some baby powder on it or rub it on your pants. It'll pick up the fabric and lose any stickyness.I used it to make a tab for an AC return vent screen. After I made the mold, I used JB Weld for the copy. Even without mold release, I could easily remove the copy. It's not a complex part but it was able to pick up fine texture details like where the paint on the original was chipped. The silicone is also strong enough to cut open, grab the part, and snap back into place for another copy.Any imperfections in the copy were from my lazy mold making and not getting the bubbles out from under the part. There was some cleanup involved, but a little extra shaking or prep work would have saved me time trimming later.The mold walls are convenient, but use better tape or another method to seal the bottom and sides. The silicone is very low viscosity and will pick up tiny details. It'll also find every little crack and try to pour out.

It will do great !!! Hard plastic fits well together.Need larger area buy a few kits very affordable.I had tried other things like taping which was notsturdy enough for my designs. Get this!!!

Complete garbage, could not contain the silicone mix and ended up everywhere.I'm kicking myself for buying two of these.It does not create a seal and I ended up losing quite a bit of silicone because of it. I definitely am returning these

Decent product that works as described but before you put the molding liquid in be sure to use a hot glue gun to go over every inch of it. Liquid does what it does- leaks out everywhere it can but if tho over each seam with a hot glue gun it keeps it perfectly sealed and works well.

work like it should but glue them down, to stop any leaks.

Probably need accelerator, but not positive if it's tin or plat, and being these China-Origin Amazon vendors it's a gamble either way.Pretty solid stuff after 24 hrs, but even a half inch deep (maybe 4x4) portion took like 6 or 8 hours to cure, and even then any parts not exposed to air end up being gooey until they're exposed. I'll use the rest of it, but plan on like a 2 day cure for anything substantial. The details and durability are good enough that I won't return it, but it says "fast curing" and that's a joke. Hence the 2 stars. If you plan on using any type of leak-able mold housing you better know what you're doing. Their "kit" is useless. Gave it a shot for experiments sake and it confirmed what I suspected, it's more of the "added value" junk attempts. Don't use their tape. Use sticky wax/casting wax and know how to apply a bead of it.

Easy to use and can be configured several ways

No instructions, but not hard to figure out how to put together. But, there is no bottom. Be careful what you use as a base. Used hot glue to cover the seams. Some seams have poor quality and don’t line up well or properly, so need hot glue for seams.
