LACQUER APPLICATION TO BRASS NAMEPLATES


(2001)

I have 4 exterior solid brass plates with engraved name and address details (blue finish). I have already removed the previously coated lacquer that has become very tarnished due to U.V and chemical atmospheric conditions. I have utilized Brasso [linked by editor to product info at Amazon] to remove all the oxidized surface then used a neutral detergent to take away any waxy finish left by the BRASSO.

HOW DO I APPLY A LACQUER TO THESE PLATES (20" x 12") WITHOUT THE LACQUER DRYING TOO QUICKLY?

Dear Clive,

After you polish the nameplates with Brasso, you need to chemically clean the piece (i.e Acetone [linked by editor to product info at Amazon] ) just prior to lacquering. The more thinner you add will cause the lacquer to dry faster, so maybe try 2 parts lacquer to 1 part of thinner. Is the lacquer blushing or fogging because of high humidities? A lacquer "retarder" will slow down the drying time, you can use between 5 and 20 percent, depending on how slow you want it.

Good luck.

I am not a lacquering expert; folks like G.J. Nikolas are. But I think the answer is that the smoother the surface you are seeking, the more coats of more heavily thinned lacquer you need.

Never mind all that, what you need to do is buy a spray can of clear lacquer for cars. Lay your plate flat, and spray away, the lacquer settles on the plate cleanly and clearly, it dries after about 10 minutes for a second coat.

Never mind all what, Alan? Cleaning the dirt and tarnish off instead of encapsulating the dirt and tarnish surface under the lacquer?
