GonefishingAZ Posted March 13, 2009 Report Share Posted March 13, 2009 The POP poured perfect only a couple small bubbles and perfectly smooth. However, I destroyed the mold. Looks like i didn't sand the flat side of the baked Sculpey worms enough and the plaster slightly wrapped around the masters. To top it off I used too much super glue and the worm masters are stuck to my mold tray. Quote Link to comment Share on other sites More sharing options...
Vodkaman Posted March 13, 2009 Report Share Posted March 13, 2009 Why no make a few more molds then. After cleaning up the plaster off the tray, fill the sides of the sculpy models with soft wax. This will prevent the plaster wrapping around the master. You should be able to smooth the wax and get a reasonable finish. Dave Quote Link to comment Share on other sites More sharing options...
GonefishingAZ Posted March 13, 2009 Author Report Share Posted March 13, 2009 Thanks for the advise Vodkaman. I hadn't thought about using wax. Is there a particular type that I should look for? Quote Link to comment Share on other sites More sharing options...
Vodkaman Posted March 13, 2009 Report Share Posted March 13, 2009 (edited) I use floor tile wax, bought a couple of kilos in a tin, all my floors are white tiles. I use it as a general release agent for bondo/resin molds etc. It is hard in the tin, but if you work it with a butter knife, it becomes soft and easy to work with. After filling, leave it for an hour or so, to harden, or stick it in the fridge. The heat generated by the plaster will probably melt it, but it will have done its job by then. You are sure to have some wax product in the house somewhere, check in the kitchen sink cupboard, that is usually where the miscelaneous junk is kept. Bees wax is a similar thing.

Milia B Posted March 13, 2009 Report Share Posted March 13, 2009 Dave i am amazed at the vastness of your knowledge ...is there anything you dont have an answer for ?? Quote Link to comment Share on other sites More sharing options...
GonefishingAZ Posted March 13, 2009 Author Report Share Posted March 13, 2009 I do have some beeswax so I will give that a try. Thanks again Vodkaman. I'm glad I didn't chuck the thing in the trash. Quote Link to comment Share on other sites More sharing options...
Vodkaman Posted March 13, 2009 Report Share Posted March 13, 2009 Milia, so much that I fail to get to grips with, for example, the painted knickers. I tried my underpants, but could only achieve 'Y' shaped spray pattern. Ah well, back to the drawing board. AZ, good luck with the bees wax, report back your results, so we can all learn.

Pitbull Baits Posted March 13, 2009 Report Share Posted March 13, 2009 Use double sided scotch tape 1/2" it's permanent but it won't destroy your master after your done with the mold. It will also help keep plaster from getting under the master also. You can over lay it for wider or longer masters. It will make the bottom sticky spray and soak with WD-40. Then wash it off with hot soapy water. It takes about two baths to get the WD-40 off. I use a spray called Airid that is made for casting and mold making. It will help get the air bubbles away from the side of the master. I did find out the better you mix and get the plaster to water right. They will seal a lot easier. Hope some of this info will help.
