Does anyone have any insight to applying silver leaf over travertine wall for lettering for a sign - I've never heard of this, but a client has asked for a spec on it - any recommendations would be appreciated. |

Jerome:
We have specified gold leaf for interior stone. Silver leaf can tarnish, and needs a topcoat. However, a potential problem with travertine is that it is so fissured (which is part of the atractiveness of the stone), that is could be difficult to get a uniform substrate for the metal leaf.
Another option we have used, especially for exterior stone, is a "monumental paint" (so-called because it is used for lettering in monuments) such as Saw Sheen by Lithichrome. It is not actually a paint, but a product that changes the reflectivity of the stone. Google "Saw Sheen" and you can get to the Lithichrome website. |

Silver leaf will tarnish without even touching it, before it is installed. I had this discussion with an installer and he will not even buy silver leaf because he cannot keep it from tarnishing.
Try aluminum leaf instead for almost identical look and no tarnishing. |

Is anyone aware of a topcoat that can go over silver leaf to avoid tarnishing? I have an interior designer insisting on silver leaf?
Anyone have a sample spec they applying silver leaf over gypsum ceilings? |

Might want to try aluminum leaf as it does not tarnish but it does oxidize.
Either way the clear coat must be (obviously) non-yellowing - pH neutral and then test test test
In the art world "mineral sprit acrylic" MSA available from "Golden Acrylic" is "the thing" but it is not a LEED type product.
and the gyp must be sized prior to application AND I'm told by David at Danial Smith that if you screw up you often have to go allllll the way dowm to the gyp and start over again.

Palladium leaf looks like silver but doesn't tarnish. |
