At Weber Fine Acoustic Instruments we take great pride in the quality of our finishes, and our varnish finish is no exception. Several years ago we made the transition from a shellac-based spirit varnish to an alkyd-based oil varnish. Oil varnishes have been the standard of quality in high-end mandolin and violin construction for generations. For years, our customers had been asking for an oil varnish option on Weber mandolins and guitars, and we listened. After countless hours of experimenting with various recipes, we are happy to offer the very best oil varnish possible. Our varnish is a proprietary blend of alkyd resins, UV inhibitors (protects that trademark Weber color from fading), and tung oil that bring out the very best in your Weber instrument.
Weber's oil varnish is not simply a product, it's a process. Many hours are spent applying, sanding, and buffing your instrument. While we do our absolute best to provide only the highest quality finish at Weber, the very nature of oil varnish lends itself to the presence of "maker's marks." For example, you might find some small surface scratches, pinholes, or "rub-throughs" upon close inspection of your new Weber instrument. A fresh oil-varnish finish is delicate. In the initial stages of ownership, oil varnish is softer than our nitrocellulose lacquer finish. Over time the varnish will continue to cure and harden. Care must be taken in order to protect your new varnish finish. Dings, scratches, and imprints are of real concern with a new varnish finish. We certainly don't expect you to treat your new instrument like a delicate flower, but we do hope you understand that varnish is a different beast from lacquer.
We take great pride in the quality and appearance of our varnish. We go to great lengths to ensure that the varnish is kept as thin as possible. This allows the wood to flex and vibrate freely, with no hindrance to the acoustic properties of your Weber. Over time the varnish finish will lose a bit of that high-gloss shine that Weber is famous for. This is a natural occurrence with varnish, and one that should be celebrated. As your finish ages, it will begin to take on an old-world luster and patina that are as unique as the music you make with your Weber instrument.
We understand that a varnish upgrade is a significant investment, and we do not take that investment lightly. Please rest assured that when you order a Weber mandolin or guitar with an oil-varnish finish that we are giving it the attention it deserves. A quality oil-varnish finish takes time, and we dedicate even more time, in an effort to make it as close to perfect as is humanly possible. We share your frustrations when you have to wait for your new Weber while the finish cures. We want you to have that instrument, but we also know that shipping an instrument before the finish is cured can lead to disappointment. Please be patient as we dedicate the necessary time to building you the Weber of your dreams. It will be worth the wait.
For the Weber gloss finish, approximately eight coats are sprayed on over a three day period. The finish is ultimately wet sanded to 1500 grit until the lacquer thickness is only .005, or five thousandths of one inch. It air cures for at least two weeks before being buffed to that high, perfect sheen for which our instruments are known.
Weber uses the same nitrocellulose lacquer for all of our satin instruments. Over time this finish rubs to a semi-gloss on the neck, where the players arm rests, on the back, and anywhere friction occurs, according to how the instrument is held by its player.
Our spirit varnish is a blend of super-blonde shellac flakes, gum mastic, and gum sanarac. It's a long laborious process, and produces the most desired and sought after instrument finish. We offer varnish buffed to a high gloss or hand-rubbed, which gives the look of a vintage satin. Because of its nature and thinness, varnish acquires a patina over time, moulding itself to the grain patterns in the wood of your instrument.
