Switch out the moldmax with omoo unless you have the extra time it takes to cure (overnight?)

And make sure your clay is plasticine & not sulfur based or it will react with the silicone.

For a 2 pc mold, yes. It keeps the 2 halves from fusing during the moldmaking process.

For production, not at first, but using the mold release helps the mold keep its oils longer.

Thanks for the info ordering tonite. lol another whole new world. I will have plenty of time for the molds to set. whats the difference in the two types of mold material, just curious if one works better than the other. Thanks

i've been experimenting w/ the platinum smooth sil 910. I just finished my final 2 part mold and haven't even had the chance to fully test it. i learned the hard way about the release agent and wasted about 25 bucks in silicone. the platinum stuff seems pretty cool (only have one pour so far) and it shows amazing detail (sometimes a little too much!). as far as the life of the mold... i'm not sure. i'm pretty sure mattlures uses platinum too, but i'm not sure which hardness (910 is the softest). Good luck w/ your mold, it took me 3 mold pours before I got one that I liked (and got the vents situated the way I wanted them).

I use vasaline when making a two-part mold, and silicone oil for a mold release about every 10-12 casts. Seem to work fine, but may not work with that particular brand.

Put a big sign up over your pouring station. Forget to grease up your mold and you risk ruining your mold. It happened to me more than once.

I've had molds tear while removing the cast. I tried a softer RTV, the result was lumps were pulled out of the mold, when I forgot to apply the vaseline to the cavity.

Yes, it is important.

do you think spraying a release agent is enough? or should i use vaseline to coat the insides of the mold too?

Sorry for the delay, you've probably already ordered.

Unless I'm mistaken, the moldmax has a 10:1 mix ratio & recommends gram scales or graduated containers to properly mix.

The Omoo is a 1:1 or 50%/50% mix. much easier and forgiving IMO.

have fun & good luck.

I found that a smear of vaseline in the cavity was sufficient.

Dave

In any other context that statement would be hilarious!!! :eek:

Seriously though, do you mean that you are substituting the release spray for vaseline when you are actually molding the lures? Or just when making the mold itself?

Ahem!! indeed.

At the time I was messing about with RTV and resin/microspheres, vaseline was all I had available. I used it for both applications, when making the mold and when casting the resin.

I have recently discovered floor wax (thanks to a TU member) and would try that as a release agent. The floor wax works great for bondo/resin molds and I am sure it would work very well for RTV and PoP.

The vaseline (petroleum gel) is a little thin and sometimes the RTV can stick very slightly, but not enough to cause damage. The floor wax, being a little stiffer, can leave surface marks on the cast, but really, these are insignificant, given the several coats of paint and top coat. I usually wave a torch flame over the wax, to level it out.

The best release agent has to be that recommended by the manufacturer.

yea I ordered already. I have access to some big siringes at work that might help me mix the moldmax, I'm thinking they would really help getting the pour into the mold without much waste. I'm sure theres plenty of help here if i get scared. Thanks guys oh an I order the manufators release spray.
