Title: Spray priming at sub-zero temperatures!
Post by: Argonor on 26 November 2013, 09:08:48 PM
I made this contraption today:

When I have added one of those flexible tubes also used for dryers, I should be able to spray minis in the conservatory at about 12 degrees Celsius, while it's much colder outside, leading out the fumes through a window. Hopefully...   lol

Smart! I built mine from a plastic packing box, with a 12V fan.

It only has two problems:the box is too small and the fan isn't powerful enough! lol

I think I might revisit the design based on this!

Nice!

Being Canadian, and having lived even north of 55, I never really had a problem with spray priming outside with cans. Just quick trips!

Now, I use an airbrush and Vallejo - a plastic tub catches overspray. So much easier.

I have had problems with temperatures below 5 degrees Celsius. Running paint.

If it's too hot, the paint seem to dry before hitting the minis, resulting in a rough surface.

Both problems MAY be related to a high realtive air humidity here in Denmark, Whatever the reason, I hope to have solved my winter problems, now.  :)

Argonor, don't underestimate the effect of humidity. Blooming in paint is a curse when it's damp!

Please be careful and do check the fan that you are using esp. if you use enamel or other solvent paints. Ordinary/household fan mechanisms are not designed to handle solvent fumes and a bit of build-up + sparks can result in a fire.  Sorry if am beginning to sound like a Health and Safety inspector.

If I recall correctly there is a nice thread on Armorama.com going a few years back on how to make a good spray box. I ended up buying one myself (Paasche) because of the fan concern.

None taken. Part of my work role is H&S too, so I have no problems with good advice, and yours regarding flammable solvent vapours is VERY good. With acrylics the fire problem doesn't arise - fortunately.

I just bodged mine up from what I had to hand! Provided I can determine the risk is properly managed, the last thing I will do is spend money! lol

There is something south of 55? What is this crazy talk? :o
