Senkosam Posted May 26, 2003 Report Share Posted May 26, 2003 Is the melting point for latex too low for making worm molds? A local craft store sells a 16 oz. bottle of liquid latex for $10. Sam Quote Link to comment Share on other sites More sharing options...
redg8r Posted May 27, 2003 Report Share Posted May 27, 2003 Hi Sam, The problem with latex is that it only cures properly in thin coats. So in order to get a mold suitable for pouring plastisol would require many many coats of latex to build it up. if you put too thick of a coat on, the top will skin over & the inside wont cure for weeks. the price you mentioned ($10 per pound) is similar in cost to RTV silicone. Take a look at Smoothon.com for "Oomoo 25" its 2.8 pounds for $22 & cures in an hour or so. You could also do resin for molds, Ive used & still use Bondo fiberglass resin. Some guys prefer plaster of paris, & Durhams water putty. Those are the most economical for guys startin out. Good luck with your craft.

Senkosam Posted May 27, 2003 Author Report Share Posted May 27, 2003 Thanks Red, I already got the plaster and Mod Podge and will attempt my first 2 part mold later this week. Sam Quote Link to comment Share on other sites More sharing options...
redg8r Posted May 27, 2003 Report Share Posted May 27, 2003 Sweet, Well if all goes well with the plaster, upgrading to RTV will give you a more durable mold & using it is similar in fasion as pouring plaster. Kidlizard uses alot of Plaster & looks like he does well with it, if you have any issues, maybe send him a private message & he could help, if need be. Good luck Sam Quote Link to comment Share on other sites More sharing options...
basskat Posted May 28, 2003 Report Share Posted May 28, 2003 I've made about 12 plaster molds with no problems. I always put a thin coat of mineral oil about every four or five pours to prevent sticking. I only pour one peice molds, although I have several 2 peice injection molds. I can't tell they catch anymore fish than the one peice molds. Later......kat Quote Link to comment Share on other sites More sharing options...
