The age-old art of grain enhancement is a process that dates back to the late 18th century and early 19th century in Europe. This process of exposing the grain by wire brushing and then filling the pore with a contrasting, yet complementary filler was also identified with the more modernistic lifestyle, even during that time period, just as it is identified today.
Earlier attempts to enhance the wood and create this effect was a very labor- and time-intensive process that involved cleaning out the pores of the wood using wire brushes; dying the raw wood using home-made stains usually produced from plants and berries; adding multiple coats of clear shellac to seal the stain and provide a barrier coat for the “ceruse” process.
The ceruse was a filler made from plaster of Paris, mixed with colorants and lime and applied to the surface, packing the plaster into the pores and leaving a small amount of excess, which would later be removed from the flake of the wood by sanding, leaving the pores completely filled with a contrasting color — usually white or a much lighter let-down of the undertone color. Multiple coats of shellac, (also known as French polishing) were applied to achieve the final protective film. This process yielded a dramatic effect and could take several weeks to accomplish.
Today, we are seeing a revival of this wood enhancement technique referred to as weathered ceruse in residential furniture, kitchen cabinetry and flooring. It continues to work well in a contemporary or casual contemporary setting and the effect is just as dramatic as before. Thanks to technology advancements, we can now produce this look in a much easier, less time-exhausting manner.

Step 1: Using a wire brush over the entire door, remove the soft grain pockets and open the grain. Prepare the surface for finish by sanding using 220 stearated paper. |
|
Step 2: Spray base stain and high solids vinyl sealer over the entire door. |
|
Step 3: Apply break-away filler, (also referred to as a break-away glaze) over the entire surface and allow to dry several minutes before wiping. |
|
Step 4: Low sheen topcoat is applied as the final coat. Typically a butyrate lacquer, conversion varnish or UV-resistant topcoat is applied where a white or light colored break-away is used to resist color change. |
|
Step 5: Using a soft, dry cloth or Scotch Brite, the panel is wiped to remove the dry powdery filler from the surface, leaving residual filler only in the pores. The formulation of the Break-away produces a clean, easy break rather than a smear. |
