Piano Finishes

[Farrell]

Most oil-based finishes - polyurethanes, epoxies, enamels, etc. and
water-based finishes require sanding between coats to provide a bond between
finish coats. Nitrocellulose laquer (most common type used for decades) has
a unique property of 100% burn-in. Each subsequent coat will melt into, or
partially dissolve, the previous coat, thus providing a great coat-to-coat
bond, and eliminating the need to sand between coats for adhesion purposes.
This feature can perhaps save about 4,000 hours (maybe more for me) of
sanding on a multi-coat piano refinishing!
