paint curing
Posted by Ballantrae Road on Saturday, August 23, 2008 8:33 PM

I just repainted a boxcar with acrylic paint. I sprayed it 4 times today and it looks good now. Should I wait till the paint cures before I begin decaling it? If yes how long?

Thanks,

Tom

If it's an all plastic box car then you can microwave it for 45 seconds (give or take depending on your oven, test on a piece of scrap first), let stand 5 minutes, then do what you want.

That's an interesting tip. Never tried that before.

Based on personal experience, I won't put any model in the oven or microwave.  I've learned to be patient and let paint set in a natural (and dust-free) environment.  I can wait, and at the same time work on something else.  I usually wait three to seven days, relying on my nose when using oil-based paints.  If there is more than the slightest smell with oil-based, I leave the model alone.  One thing is sure, paint has to be absolutely set before applying masking type in preparation for applying another color.  Anyway, those are my thoughts based on modeling off and on since 1962.

Be impatient and ignore me, but you will be only following footsteps of my youthful ignorance.

If you have an old gas stove with a pilot light it is perfect for drying paint. Just leave it in overnight.  Be sure to tell your wife it is in there however and put a couple of pices of masking tape across the dial.  We won't go into why both are necessary.

Gas can drying oven, (for both painting and decalling):

use 75w bulb 0r 100w with a dimmer, use an oven thermometer to calibrate the dimmer.

 Paint shop tips;

  I use all acrylic paints purchased at WalMart, Hobby Lobby and the like. The mix well with acrylic caulking, acrylic water sealant and anything else for scenery. When painting military models (the other side of the hobby) and any RR items I use a hand-held hairdryer set on LOW heat.

 This is the greatest thing since acrylic paint and works like a champ to dry and set the paint. Also for mass painting try using the new H2O paints that you can use indoors. I still use them outside for big diorama jobs and they cover a lot of "ground" for the base colors.

 Best of luck,

  With many of the new acrylic model paints, you can mask/decal within hours.  The old solvent based paints(Scalecoat/Floquil) would take days.  I would hold the model close to my nose and 'smell' it to tell if the paint was really dry.  My question is why do you have 4 coats of paint on that model?  It may take some time for the lower layer to dry with all of that paint.  I doubt if I have ever used more than two coats to cover.  C&NW yellow was one that needed a second coat, even with a good primer base under it.

I agree, 4 coats is a lot. But I didn't like the first color so on the 3rd and 4th coat I changed it slightly.. Looks Ok now. I've been busy the last week and haven't had a chance to decal and I'll be away for another week on vacation....should be dried and cured fine by then.

Tthanks for all the replies.
