Silicone Mold Making Kit - 2.2 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

Great means of replicating concrete sconces. We made 3 molds from the one gallon kit, only because the resin initially leaked from from the bottom of the form, so use a better means of sealing the form to the base as the double sided tape is thin and tantamount to useless. With forethought I also purchased an extra set of mold forms for a deeper pour.

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.

I Recently decided to try my hand at mold making. the first frame I brought was from another company, it worked well. I wished to make another mold but needed more sections to make it bigger . This one was cheaper but looked about the same as the other one I bought. To start with it was smaller then the first. I decided to try it out anyway . the sections did not fit together very well . I sealed the bottom with my glue gun , used the tape on the joints . it still leaked badly. after I finished I could not get the tape off. I ended up ordering from the other company.

For a product that states a 1:1 mixture you might think the two parts would have equal amounts, which they didn't, in both purchases I've made. The product itself does work fine, just mix longer than you think you might have to and you shouldn't have any issues. The picture showing food grade and the note saying not for use in contact with food should be clarified to greater extent!

functions just as shown. It's sturdy, no leaks, can change the size, and the a fine job. I just wish it came in larger sizes!

Great product still working on the pattern to pour in to create the silicone mold.

I have trouble using this every time I set it up. I use tape for the seams and I even hot glue gun the base but I still get very slow leakage Everytime I use it. I would probably be better off with some this strips of wood and hot gluing those down so there aren’t any seams. I have been using this to make silicone molds and the viscosity is so thick that I don’t lose enough product to ruin my project but it does make a mess!

Pretty sure I got a previous used/opened product. There were some plastic pieces sticking out I had to file. I kept it after fixing it and it works great.

I purchased this liquid silicone to make moulds of items I want to cast in Resin. To be honest, I have not tried this product yet, however, when I start to use I will update my Review and tell what I thought of the product, the hardness and what my thoughts are of this “Liquid Silicone” are!!

You would think there would be no leakage through the joints. What a mess. Cleaned up, for round 2 I'm using a bead of silicone adhesive in the joints. Will see how well it works this time.

يجب الإنتباه قبل الشراء حيث أن المنتج الذي وصلني عبارة عن اجزاء الإطار البلاستيكي مع مشابك للتجميع فقط بدون قاعدة، اي انه عبارة عن اطار ليست له قاعدة ليتشكل لدي صندوق لصب الصابون، وبالتالي لا يمكن استخدامه بشكل أو بآخر في تصنيع الصابون ولا انصح به

This isn’t made very well. The pieces don’t come together flush.

Awesome stuff
