I was watching some guys paint some open metal mesh
using a pneumatic sprayer and we discussed how much
paint was inevitably wasted - over 80% we reckoned.
The
Circular Paint Sprayer (CPS) minimizes paint over-spray
and loss by having the over-spray sucked back through
the
system
for re-use. The CPS has a two-pronged handheld
component which
emits the paint through a curved hood towards a larger,
funnel shaped opening on the other prong. This second
opening is Teflon coated and pneumatically sucks the
paint
back into the system.
By getting the paint droplets back
into the system quickly and mixed with new paint they
avoid drying and are good for a few more cycles until
finally contacting the solid surface to be painted. Simply
hold the CPS up to the mesh and avoid the mess.

I'm all for less wastage, especially when it's toxic to the
environment. + |

It's what electrostatic spraying was made for. |

Electrostatic spraying also allows you to sit in a chair,
waving the sprayer in the general direction of the object
with one hand, while focusing on pie eating with the other.
The ideal work setting. |

You know that feeling, when you see the ant with the hard
to carry thing, and it's struggling and tumbling and barely
getting anywhere and you feel pity and schadenfreude
because it just seems so ridiculous, and then you realize
that that ant has more drive and direction than you will
ever have, and more clarity of purpose than you can even
imagine. Ignore the fact that the prize is a worthless sugar
soaked piece of plastic, panted fence or whatever, and just
revel in the fortitude of the project itself. |

The object being sprayed was a safety rail on the top of a
truck and the guys spraying are my employees who had
ably
sprayed all the handrails, steps, etc safety yellow
without
much issue but then had the steel mesh panels to
contend
with. As I'm the guy buying the paint but didn't want to
purchase/hire an electrostatic spray unit I thought a
pneumatic adapter would do the trick as we already had
compressed air in use. |

I do agree on the 'magic wonderfulness' of electrostatic
sprayers. |
