Best humidity to prime miniatures

priming miniatures in the right humidity

If you’re getting poor results with your mini priming it could be due to the climate, and the humidity in particular.

When first starting painting minis, it’s easy to just spray away with the grey, white or black primer and assume a poor finish is down to your technique. At least, that’s what I assumed for a quite some time.

It wasn’t until sometime later that I realised the climate had a lot to answer for.

No, I wasn’t spray painting in the rain 🙂

Back then, I was living in a small village in the middle of a huge area of marsh land, a place called Rommey Marsh in the South East corner of England for those interested. And the humidity there was invariably high, rarely dropping below 70% if I remember and often much higher.

I rarely got the results I wanted and have since learned this was more than likely due to the humidity being way to high.

Priming at this level plays havoc with the drying process as the moisture in the paint can’t evaporate. I ended up with an uneven finish where the paint dried at different speeds.

I now live in Surrey which has a far more primer harmonious humidity, with levels consistently around 55% which is near to the ideal 40% to 50% for priming minis and other plastic models.

So if you’re getting odd results with the primer on your miniatures check your humidity levels. If they’re too high, either move to Surrey 🙂 or putting the minis in a well ventilated spray both.

A colleague also suggested keeping piles of salt around the mini. I can see how this might help but never tried it. I’d be interested to hear any other suggestions for dealing with humidity if you have them.

>A final, personal, note: I spend a huge amount of time testing, photographing, writing and researching techniques for these articles and pay for all the running costs of MRE out of my own pocket.
