Using liquid latex mold maker as a mask over acrylics...

Post by Lt. Z0mBe »

Wise and Sagely Modelers,

I bought some liquid latex mold builder today, both to make some simple molds and to use as a liquid masking agent.

I notice it's got ammonia in it. If I use it as a masking agent over something finished with Future, or an acrylic paint, will it damage said coating?

I appreciate your advice.

Yep

Shoot enamel over your acrylic and you won't have a problem.

So that's why...Okay one more question. I've already used future on this canopy that I've already used liquid latex. I'm guessing that the fogging is due to the ammonia in the liquid latex. How do I remove the fogging?

Unless you used CA glue to attach the canopy. CA glue give off vapours which form a foggy film. I've never had any luck removing it, but some say that polishing will work.

It's easire to not use CA to attach canopies, though.

No. I don't use CA to glue canopies, because of that reason. I'm assuming that the ammonia is reacting to the Future. I'll try polishing the canopy to see if that works. Thanks.

Redip it in Future and your fogging will go away. :)

You might want to use some alcohol and a cotton swab to clean the canopy first.

Can't redip the canopy in Future. The canopy is already attached to the cockpit already. I'll try some alcohol and the cotton swab. If not, I'll try buffing it out with a paper towel. Thanks.

After you clean with alcohol, then re-coat the canopy with Future - use a clean brush or cotton swab. it works.

wisdom says ammonia and acrylics aren't buddies..

but if its mold builder...in a fat little white/blue tub...prob picked up from Michael's crafts...

I use it regularly....over acrylics...Tamiya and Model master...and it doesn't harm them....no color probs...no pulls...nothing.

trust me..

but try it on a test piece if you don't believe me..

only prob i have with it...it's a little thick...so doesn't work great for tiny tiny masking.

You can thin it to suit with distilled water.

Yeah, I got it at the Michael's in E-Town. I'll test it on a piece of clear styrene with Future. Thanks everyone! :)

Liquid latex is always used in theatrical or costume body paint and make up. Each has its own effects and length of duration. Body paint can involve just the face or it can be a full-body design.
