STAINS & FINISHES
CEDAR SHINGLES SIMPLIFIED
1. Stains.
Quality stains are formulated with penetrating type oils, usually providing a flat finish. Semi-transparent
stains permit the natural wood grain and texture of Shakertown siding panels to show; solid stains are
used when an opaque, colored appearance is desired.
“Weathering” stains provide protection for the wood while allowing it to develop its natural coloration.
These are usually soft gray transparent stains, providing a transition to the eventual weathered color
without hiding the beauty of the cedar’s natural color and grain. It is important to use any stain in
accordance with the directions of the manufacturer. Proper mixing and application are essential
because of the thin consistency of the product. Frequent mixing is imperative to assure uniform
dispersal of pigments across the entire job.
2. Paints.
Stains are the recommended finish agents for Shakertown panelized cedar products as they allow
natural moisture to escape without causing blistering and cracking of the coating film. In situations
where a thicker coating is required, however, an exterior latex paint may be used.
These paint films are more porous than those high-gloss oil-base paints, and thus are more likely to
allow the escape of moisture without adverse results.
Discoloration of the natural cedar can usually be avoided by sealing with a good quality solvent primer
or a latex primer specially designed for resistance to staining. Many paint manufacturers sell products
specially formulated for use over natural cedar. Since early application is essential to the effectiveness
of such finishes, prefinishing may be the preferred approach. (See Section 8).
3. Wood Preservatives.
Wood preservatives are fluid materials which penetrate into the wood, leaving little or no film on the
surface. They are usually very effective at resisting rot and decay and in discouraging the growth of
molds and other vegetation on the surface. Western Red Cedar is very resistant to decay, and preservative
treatments are required only under extreme conditions. Since there is little pigment or surface film,
they offer little protection against color change and do not protect against wear and abrasion where
needed. Clear wood preservatives containing a water repellent agent are recommended.

4001 TECHNICAL BULLETIN
Since Western Red Cedar is a highly durable species, Shakertown siding
panels can be left unfinished where a truly low-maintenance weather surface
is desired. Many specifiers and builders, however, prefer to apply some
type of finish to shingles, whether to obtain a color effect or to provide an
early impression of the gray weathered look. While such finishes can be
applied after the product is installed, prefinishing is an efficient and
economical approach. This is particularly true where cedar is being used
in combination with other siding materials for architectural effects.
Shakertown siding panels may be prefinished by breaking bundles at the
job site and staining or painting by conventional methods; or by a
commercial applicator prior to delivery to the job.
The beauty of Western Red Cedar is enhanced by its natural color variances.
Stains and finishes can augment or subdue these natural characteristics.
