macbor Posted June 25, 2008 Report Share Posted June 25, 2008 Hey, I made a jig trailer mold like the Yum Chunk, sealed it with 2 coats of 50/50 glue and water, did my first pour and the plastic is sticking to the mold when I try to remove the bait???? This is my third pop mold, but this is the first time having this problem Should I seal it again? or is there somthing else I can do Thanks Rich Quote Link to comment Share on other sites More sharing options...
Vodkaman Posted June 25, 2008 Report Share Posted June 25, 2008 With only two coats of 50/50, you probably have not filled all the pores of the PoP. The surface of PoP is like a micro sponge, all the pores give the plastic something to hold on to. I would add another couple of coats and give the final coat 24 hours before pouring. The time may seem excessive, but by this time you have invested a lot of work, so why risk spoiling it. When the elmers is dry, it should have a shiny surface. If it is the slightest bit dulled, it needs at least another coat. Quote Link to comment Share on other sites More sharing options...

Vodkaman Posted June 25, 2008 Report Share Posted June 25, 2008 I'm actually sealing some PoP right now. The fifth coat went on 30 mins ago, and it is still not ready. Number six goes on at bed time and will throw another on regardless, before I leave for work in the morning. I think that the original mix of the PoP could have an effect on the sealing. This particular mix was 1:1 by weight. It was a bit thin and had some water left on the surface. So maybe the pours pores were larger than a thicker mix. I know I don't normally require this many coats. Quote Link to comment Share on other sites More sharing options...
Hookfin Posted June 25, 2008 Report Share Posted June 25, 2008 As the pop starts to set it will heat up in curing..that is when I fill the mold with the 60/40 let it get pulled into the mold...dry...repeat..dry...repeat...dry...don't get discouraged..take your time.

HJS Posted June 25, 2008 Report Share Posted June 25, 2008 (edited) Rich - I'm assuming you let the mold dry out completely before the first coat of Elmers is applied. Might take a couple of days to air dry, much faster in an oven set at low. I've set my drying molds on the dash board of my Jeep Cherokee with windows up... really hot in there. At the least, apply 1 or 2 more coats of Elmers. When I'm pouring plastic, I spray the molds with PAM kitchen cooking spray. Just one really quick pass over with PAM is enough. Then turn mold cavity down on a paper towel to drain any excess oil while you're heating up the plastic. Lures almost drop out. PAM must be reapplied after 3-4 pourings. You'll know when the mold needs another spraying. Edited June 25, 2008 by HJS Quote Link to comment Share on other sites More sharing options...
