fishing nut Posted September 13, 2004 Report Share Posted September 13, 2004 when ever i make a two part mold out of plaster the first half comes out great. However whenever i go to pour the second half there are always bubbes. Any suggestions on how to get rid of this. Quote Link to comment Share on other sites More sharing options...
bass ackwards Posted September 13, 2004 Report Share Posted September 13, 2004 try taking a paint brush and painting a layer of plaster onto your model instead of just pouring it over it. After you have brushed on a good layer pour the rest of your plaster slowly and into one corner of your mold box so that the plaster slowly rises over your model. Make sure not to pour plaster directly over model because it can trap air! That should do the trick! Quote Link to comment Share on other sites More sharing options...
