Historic clocks are wonderful examples of craftsmanship and art coupled with precise mechanical engineering. In restoring one of these works, the painting and detailing of the clock proves essential to re-establishing the original grandeur of the piece. Discussed below are the procedures utilized by Princeton University's EPICS Time Team in restoring Isles' Trenton Factory Clock.

Primer and Base Color

Based upon residual paint on our clock, the original hue - a vibrant shade of forest green - could be discerned. Before applying the final coat - a water-based matte shade of interior paint - a primer was applied. The primer utilized was an interior paint primer, in a color a couple of shades lighter than the final base coat. One coat of primer was applied, followed by a substantial coat of the final color. Allow the paint to dry between coats, and avoid dripping by using even strokes and a medium to stiff bristle brush.

Detailing

Once the final coat has dried, detail work can be added to the clock. Research your particular clock for appropriate color schemes from the time period. Our original clock had a deep forest green base color, with black and gold accents. To achieve this look on our restoration, metallic gold paint was utilized. Details - primarily lines and arches to accentuate the clock's elegant curved legs and main body - were either added by painting free-hand with a soft to medium bristle brush or by utilizing painter's tape to establish a straight line which could be filled in or traced.

Detailing Tips:

To paint curved lines or circles, use electrical tape to outline the edge. Electrical tape can be stretched and pulled, giving rise to a smooth curved line, whereas painter's tape and masking tape can only easily produce straight lines.

In the particular time period of our clock, hard, straight lines were not in fashion; alternatively, curves and rounded/tapered edges were utilized. To attain this effect on the clock's surface, all hard lines were rounded off by painting a semicircle at the line's end. This way, a more delicate, rounded look was achieved.
