Subject: [Puptcrit] TECH: super-speeding the cure of latex


I have not tested it yet (just broke my thrusty spray bottle yesterday, need a new one), but this trick looks very interesting. I wonder if it only works when spraying the latex... I don't think the airbrush I have would support latex spraying, and I don't know what solvent to use...
Maybe add more amonnia (some people use nastyer solvents for this) ?

William and Ax, oh Latex masters, have you any insight into this to share with us?



Here's the trick I found on a forum:
----------------------------------------------------------------
You may not only spray the latex to make molds but you can also expedite to make it practically instant which may be news to most of latex mold makers.

You must however check if the viscosity is suitable for the nozzle you are using. 

In order to expedite the mold making you may want to mist the master with a very very ligt mist of vinager. The minute the amonnia based latex hits it it will instantly turn into to latex rubber. Once the layer is formed mist it with vinager and latex and on and on until you get the thickness you desire. Make sure you do not over spray vinager. If that happens it may turn runny. 

Before you use a master you may want to experiment on a piece. Results and speed of the process may amaze you.
