frankC Posted November 30, 2015 Report Share Posted November 30, 2015 I have a mold with some micro bubbles, I'm worried the plastic will pick up on the bubbles if I seal them in. I will be using Elmers glue to seal the mold. Can I mix up some POP to rub into the mold and smooth it out before I seal it? Or will these new pieces not bond with the mold Quote Link to comment Share on other sites More sharing options...
Vodkaman Posted November 30, 2015 Report Share Posted November 30, 2015 I think JRammit wrote something on these lines not so long ago and it worked. When you apply the seal coat, it stitches it all together. Dave 1 Quote Link to comment Share on other sites More sharing options...
Bogbaits Posted November 30, 2015 Report Share Posted November 30, 2015 You did not mention what your mold was made of,if its made of plaster than yes you can,I have done this many times,you can also use epoxy,wood filler,ive used those also 1 Quote Link to comment Share on other sites More sharing options...
Travis Posted November 30, 2015 Report Share Posted November 30, 2015 Yes, no problem with doing it that way. Mix it thick like putty and then fill. I don't let it set all the way just a few minutes then you can use a q tip, finger, or rounded dental tool. A little water on a sponge also works well. 1 Quote Link to comment Share on other sites More sharing options...
JRammit Posted November 30, 2015 Report Share Posted November 30, 2015 Ive had to patch more holes than id like to admit in my molds Ive tried bondo, then ruined the mold trying to sand it down Wood filler worked, but could not handle the heat from the plastic Tried filling in with strait wood glue, took too long to dry and runs all over the place Plaster on plaster is your solution... Just brush it on like paint... If you get rough spots, brush over those with water..... Weather it bonds or not doesnt matter, the sealer you apply will hold it together 3 Quote Link to comment Share on other sites More sharing options...

Bogbaits Posted November 30, 2015 Report Share Posted November 30, 2015 Just wanted to add if your using epoxy to coat your mold than you can use almost anything including wood filler,bondo,even epoxy to fill the holes before you apply the sealer coat Quote Link to comment Share on other sites More sharing options...
JRammit Posted December 1, 2015 Report Share Posted December 1, 2015 (edited) Just wanted to add if your using epoxy to coat your mold than you can use almost anything including wood filler,bondo,even epoxy to fill the holes before you apply the sealer coat Good point, as the epoxy will form a hard shell, it won't matter whats under it...... But for ease of use, plaster still gets the nod from me I forgot to mention that most of my molds are DWP (Durhams water puddy)... With the DWP, you can mix it thicker and still get more working time in the cup... But when its thinned out, it nearly dries on contact, perfect for patching holes cause it has no time to drip or run I see no reason why you couldnt use DWP to patch holes in a pop mold, i havnt tried it, but it should work Edited December 1, 2015 by JRammit 2 Quote Link to comment Share on other sites More sharing options...
