Curb appeal starts with cedar siding. There are so many different grades and profiles to choose from to suit every style of home. Whether you want to create a warm textured shadowy effect or keep your lines clean and polished, there are many western red cedar siding products that can fulfil your desired effect.
Once you choose your siding profile, the next step is deciding on the right finish for your exterior. This mainly comes down to personal preference and the look you want to achieve. Revered as nature’s most versatile building material, Western Red Cedar accepts and holds a wide range of finishes beautifully, which means you can finish your home however you like – be it a modern home stained black, an East Coast beach home painted white or a West Coast contemporary home with a natural finish.

Important Note: All these types of finishes can be factory applied for optimal results. But if you choose to finish your siding on site, follow best practices and apply products to all six sides of each board.
While many homeowners prefer to showcase Western Red Cedar’s beautiful texture and color with a natural finish; some prefer to use a solid finish. This can be just as beautiful – think New England cottage and traditional craftsman home. Both styles are perfectly suited for a vibrant coat of color. Whether it’s solid stain or paint, Real Cedar offers a complete list of siding application tips. The first rule of thumb? Use a primer.
Reason being Western Red Cedar has naturally occurring extractives – it’s what gives the wood such that stunning tonal range, and it’s just one of the many benefits of cedar. But without a proper base coat, those same extractives may discolor opaque finishes such as latex paints and solid-color stains. That’s why it’s always best to use a stain blocking primer, preferably alkyd-oil and water-based formulations. Alkyd-oil based primers usually offer the best shield against discoloration by water-soluble extractives.
The label on the container should indicate that the coating is recommended for use as stain blocking primer for Western Red Cedar.
The Flood Pro series by PPG Paints comes in a wide range of exterior stains that are ideal for Western Red Cedar products. To add a rich, long-lasting opaque color, there’s PPG’s 100% acrylic stain which protects against sun and water damage. And to slightly tint your siding with color pigmentation, UV5 penetrating wood finish is a sound choice. The Penetrating Oil Wood finishes are excellent water-repellents that penetrate easily and are formulated with mildewcide additives.
Sansin Precision Coat finishes are also highly recommended for Western Red Cedar siding. The SDF is a one-coat formula that provides strong, long-lasting protection for cedar siding. For added protection, complete with a layer of SDF Topcoat on siding, trim and timbers.
Another option is Sansin Precision Coat Factory ENS, a self-priming clear satin finish that requires two coats. It offers premium adhesion and superior UV protection.
Compared to other finishes, paint offers the greatest protection for western red cedar siding against the elements. And while cedar siding accepts, holds and showcases all types of paints beautifully, your best choice is a 100% acrylic latex formula. They outperform other types of paints in all types of weather.
As with paints, solid-color stains shield WRC from damage caused by ultraviolet light and water. These stains come in a wide array of tints that defuse cedar’s naturally occurring brilliance, but unlike paints you still get all the warm texture of wood shining through. It’s important to keep in mind, though, that unlike non-penetrating stains, these finishes form a film. These stains come in latex and oil-based formulas. When it comes to recommended usage, DO apply a stain-blocking primer before applying solid color stain but DON’T use an oil-based solid color stains over a latex primer.
Important Note: As with paints, 100% acrylic latex stains are recommended.
Let your wood’s lustre shine through. If you love wood’s natural characteristics but want to provide some protection against the elements, transparent stains are the way to go. These non-tinted products highlight cedar’s natural beauty while providing water repellency. Look for products that contain mildicide and fungicide. This will help prevent future growth of mildew and fungi and prolong the wood’s service life.
Among the different types of transparent stains, there are waterborne and solvent-born formulas. Both of are completely unpigmented, which means they require regular reapplication because they don’t offer any protection against damage caused by the sun’s ultraviolet rays and moisture. But like all transparent stains, they can be refinished with relative ease.
Solvent-borne, oil-based, semi-transparent, stains penetrate the wood surface. They do not form a surface film like paints or solid stains. For Western Red Cedar products, they are the best choice in terms of offering protection, yet they still showcase the wood’s natural beauty. They can be used on both smooth and textured boards but absorb better and last longer when applied to textured surfaces. They do contain pigments that add color – including cedar tones. They will increase the service life of your siding and protect if from damage caused by ultraviolet rays. If applied according to best practices and depending on design and exposure to weather, these stains can last 3 – 6 years before having to be reapplied.
With latex semi-transparent products, you can achieve the same look as solvent-borne ones. However, these stains tend to form a film and do not penetrate the wood. This can lead to flaking and shorter service life. But from an environmental standpoint, latex formulas are a good option.
These products are designed to provide the weathered look and do so sooner and more evenly than natural exposure to sunlight. They are lightly tinted with either grey or brown pigments, which mute the natural coloration in Western Red Cedar, accelerating the weathered appearance. They are available in oil-based and latex formulas and like all finishing products, should be applied to all six sides of each board. Pay special attention to the ends of siding and trim as well raw ends or end cuts, and be sure to touch up any raw ends with either a base coat or primer coat. This will provide color consistency as well as equal water repellency to all six sides.
Important Note: With all types of finishes, the manufacturer’s recommendations should be followed. Western Red Cedar’s excellent finishing characteristics cannot compensate for finishing products that are unsuitable, of inferior quality, or improperly applied.
* HOWEVER, you can ignore manufactures’ recommendations to wait six months to a year prior to applying their products.
For optimum performance, the WRCLA recommends that Western Red Cedar is preprimed or pre-finished prior to job site delivery. Factory-priming, as the name implies, is performed in an industrial setting where a machine coating process applies a coating to all six sides of each board. The coated boards are then dried prior to shipment to the job sites. Pre-primed siding and trim boards delivered to a job site should be kept dry and clean prior to installation. All field cuts should be re-sealed with a primer prior to the boards being installed. Top coating should be completed as quickly as possible as most primers are not intended to be exposed to natural weathering for more than 90 days.
Factory–finishing is similar to the above process, however, it allows for the additional application of one or two topcoats of acrylic latex paint, solid stains or natural stains in job lot quantities and in the colors selected by the builder/homeowner. It is important not to overdrive nails during installation of factory finished siding, as this will damage the surrounding wood and coating. Overdriven nails must be remedied immediately by filling the depression with exterior grade wood putty specifically designed for this purpose.
Touch-up any repairs or field cuts, taking care not to smear the top coat. Properly done, factory priming/finishing provides:
