Yep - you guessed it: From one of our interior designers.

They want to know if "Electric Static Paint over Stainless Steel Elevator Frame" is in the specs.

Of course it isn't.

If someone would be so kind as to point me in the direction of a good resource - other than my local product rep (I'm already chasing that avenue) - it would be very much appreciated.

I also welcome comments (flippant and otherwise) with which I might reply to our Interiors folks.

Thanks in advance.

You mean aside from the question as to why anyone would schedule new stainless steel to be painted, as opposed to paining “convention steel”? How about “How do you explain to the Client the fact that you wasted money painting stainless steel?”

David,

Assume that it is old discolored stainless steel. Electrostatic painting was common in a firm I worked for in the 90's. We were remodeling government buildings. There was one applicator who was very good. I have a guide spec if you want it. E-mail me at wdwalkerspecs@comcast.net

Ellis,

Elevator frames are existing; not sure what condition they are in. Since this is an interior renovation project, my only guess is that the stainless did not work with the color scheme.

SSINA and NDI are both industry organizations that "promote" use of stainless steel. They might be able to help answer any technical questions.
I've been told that bonding to stainless steel is paramount, as stainless steel is difficult to "get anything to stick". Thus, surface prep is probably most critical than with most "other" types of substrates. Mechanically abrading/blasting to obtain surface profile "as recommended by (primer) coating manufacturer" is how I've previously spec'd painting s/s...generally with a high-perf primer product, at least a DTM if not an epoxy.

Electrostatically applied paint is a process, not a product. There are excellent quality coatings available that can be spray-applied with good results. It is not necessary to electrostatically apply a coating to stainless steel. And good luck finding an interior painter that can apply it!
