Users of gold-leaf liquid paint are strongely encouraged to apply clearcoat to preserve the initial luster of the bronze alloy flakes mixed in the coating material.
Tip #1: Test the gold liquid paint to insure the coating is entirely cured.
Press thumb against paint and twist. Any sign of your thumb's imprint...wait some more
Reason for waiting: Clearcoat will "suck up" any drying paint, causing a cloudy look.
Tip #2: Apply clearcoat as you would nail polish to your nails (or, if you are a guy, imagine this scenario)--once quickly. Do not work the brush into the coating, and if you see any gold, STOP. Refer to Tip #1 above.
Tip #3: Apply second clearcoat application as above in order to cover the spots missed by the first coat. If you overlook any exposed gold paint, that area will age.....blocking the aging is why you are applying clearcoat in most cases.
Tip #4: If you do not like what you have done, just recoat with the gold-leaf (or copper) paint.
The luster of the gold liquid paint is due to bronze alloy flakes....that age with the impact of air pollutants and moisture. The shore with its proximity to the salty sea air is a good example.
The clearcoat that is available through us works. Other clearcoats also work......but some don't.
This sign maker elected to use his own clearcoat with a fading that occurred within three months.
