Traditional Finishes

Basics of Woodworking Series Level: Beginner

Introduction

The traditional finishes - oil, wax and shellac are easy to apply and simple to repair when damaged. These are great virtues. The traditional  finishes can be a little more finicky to use than contemporary finishes but they reward you with a wonderful depth of grain and a sensous feel.

There are many varieties of Shellac - the most commonly used Shellac is dewaxed and has the amazing ability to bod and seal both wood and prior finishes. The raw, waxed shellacs are very underappreciated. Seed lac, button and many other varieties of Shellac have great colour, build well and can provide more protection then the dewaxed shellacs - you'll get a chance to use them and appreciate the differences.

The greater part of finishing is the surface preparation before applying the finish. We look at the traditional techniques for preparing the surface of the wood - planes and card scrapers which leave the grain in the wood cleanly cut. That is not to say that abrasives don't have a place in the workshop but abrasives should not dominate the surface preparation.

Shellac and oil finishes do need to be used with solvents but, we argue, the volume of solvents used in the average, well ventilated home shop does not pose a significant environmental risk compared to the quantities of solvents used in production finishing. We teach you how to minmize the use of and to recycle solvents.

These finishes are prepared in the volume needed for the work at hand and, if managed carefully small quantities can last several years.

In the final part of the course we'll look at techniques for working with varnishes.
