TNBasser Posted April 13, 2008 Report Share Posted April 13, 2008 I have completed carving several wood prototypes from Basswood which I intend to use for producing RTV molds. What is the best product to use (varnish, shellac, etc) to seal these prototypes so there are no problems in making the mold? Quote Link to comment Share on other sites More sharing options...
nova Posted April 14, 2008 Report Share Posted April 14, 2008 I seal mine with tremclad spray can paint with fine steelwool rubbing in between coats.(usually 3 coats) Comes out nice and glassy. Let the paint cure for a couple of days before you mold it. www.novalures.com Quote Link to comment Share on other sites More sharing options...
bassn1 Posted April 14, 2008 Report Share Posted April 14, 2008 I use regular sanding sealer from Home Depot. Dip 2 or3 times and sand with 220 between coats and let dry overnight. Quote Link to comment Share on other sites More sharing options...
gofish,ill Posted April 14, 2008 Report Share Posted April 14, 2008 would the same sealer apply for making pop molds? Quote Link to comment Share on other sites More sharing options...
bassn1 Posted April 15, 2008 Report Share Posted April 15, 2008 would the same sealer apply for making pop molds? Home Depot sanding sealer wont work for a pop mold....cant take the heat. I tried to coat a prototype for dippin' and it just bubbled off in a matter of seconds. Use elmers glue mixed 50/50 with water for a cheap sealer.

Tman2 Posted April 15, 2008 Report Share Posted April 15, 2008 Some guys use a thinned down Devcon sealer and put it in the oven between coats. Search POP sealer and you should come up with some options. Quote Link to comment Share on other sites More sharing options...
Tman2 Posted April 15, 2008 Report Share Posted April 15, 2008 Back on track, Palmetto Balsa is selling something for sealing wood baits, I believe. Quote Link to comment Share on other sites More sharing options...
