Sealing Molds

[Draco]

Ok, this time I took all the advice from the vetern users, I did a search, I check the sticky topics and the FAQ's but I still cannot find an answer to this question.

I just got some new rubber molds, and I did get some mold sealing putty from the candle suppy store, but I was not exactly inexpensive. I am looking for ideas on a cost effective way of sealing thease two piece (top and bottom) molds so that I do not end up with a mess of wax leaking from the sides of the mold.

Can we see a picture of your mold? The rubber molds I have are seal just fine by lining up the seams and putting a rubber band around them.

The other two piece molds I've got are plastic, well except for one silicone mold that makes things to be glued together later, but no need to plug them. I have some silicones with splits in them that a rubberband around it works fine to hold into place.

Sure, picture is attached this this post.

Thank you for the help.

It's kind of hard to see, but it does look like it's probably a self sealing mold so you should be able to get away with just rubber-banding it and it should be fine.

Use whatever method you wish, but realize that when using molds, wax DOES leak at some point. I set my molds up inside a flat pan or plastic bucket or other clean container so that when they DO leak, no problemo.

Well thank you all for the help everyone, I found out that they are not self sealing, the hard way, LOL!

A bit of puddy around the entire edge is what it took to keep my wax in. Oh well, live and learn.

Another sealing question though, I have sean some type of foil tape used to seal molds, but I have no idea where to find it. Does anyone have any idea what it is called and where to get it?

It's aluminum tape and you should be able to find it in the hardware section.

Have you used that Ducky? Does it work well?

[Scented]

Not Ducky, but I gave up on that. Hadn't seen a mold like what you have sooooooo didn't offer any more advice. How bad was the leaking?

[SatinDucky]

Have you used that Ducky? Does it work well?

On a silicone mold? NO. On a tin mold that I didn't want to wick, yes and it's works great

I only have a couple silicone ones so I don't have the best answers. What I've done personally....

1. I have a thick silicone mold that a rubberband holds fine.

2. One softer mold, I set it on top of a pillar mold (so it'll sit flat even with a wick or pin sticking out) put a piece of scotch tape around the seam just to keep it from shifting and pour gently, then DON'T touch it again until it sets up some so it wont leak

Well, i just got myself some mold tape from eBay, so I will let you all know how this works out.
