Staining cedar wood is an excellent way to enhance and protect its natural beauty. Cedar has natural oils that make it resistant to rot, decay, and insects, but it still requires protection from the elements. Proper staining can maintain the rich color of cedar while shielding it from moisture, UV rays, and other damage. Here is a comprehensive guide on how to stain cedar wood to protect it for years to come.
Choose the Right Type of Stain
When selecting a stain for cedar, consider both the color and the type of protection needed.
Oil-Based Stains
Oil-based stains are ideal for protecting outdoor cedar furnishings. The oils penetrate deep into the wood grain to provide water repellency and UV resistance while accentuating the natural patterns and color variations of the cedar. Oil stains bring out a rich, warm glow in the wood.
Water-Based Stains
Water-based stains work well for indoor cedar surfaces like cabinets, trim, and furniture. Water-based stains are lower in volatile organic compounds (VOCs) and offer great color selection. They provide less moisture protection compared to oil-based stains but offer good UV resistance.
Clear Wood Sealers
Clear sealers contain no pigment but provide excellent protection against weathering. They help stabilize the color and texture of cedar. Clear sealers are a good choice if you want to maintain the light, natural color of new cedar.
Prep the Wood Surface
Proper preparation is key to achieving long-lasting results. Follow these steps:
- Allow new cedar to weather 2-4 weeks before staining. This reduces tannins leaching out.
- Sand the wood with 120-150 grit sandpaper to remove mill glaze and roughen the surface. Always sand in the direction of the wood grain.
- Remove all dust with a brush or compressed air. The wood must be completely clean and dry.
- Apply wood conditioner to softwoods like cedar to regulate absorption and prevent blotchiness.
- Fill any holes, cracks or defects with wood filler and let dry completely.
- For previously stained cedar, use a wood brightener to remove old stains and grayness.
Apply the Stain
Careful application techniques ensure even coloring and maximum protection:
- Always read and follow the manufacturer’s directions.
- Stir the stain thoroughly before and during application.
- Use a high-quality natural bristle stain brush for best results.
- Maintain a wet edge to prevent lap marks by brushing back into previously stained areas. Work from the bottom up.
- Apply stain in the direction of the wood grain. Use thin, even coats.
- Allow the first coat to dry per the manufacturer’s recommendation before applying a second coat.
- Two thin coats of stain provide better results than one thick coat.
- Remove any excess stain with a clean rag before it dries.
Protect and Maintain the Finish
To get the most out of your stained cedar, provide regular maintenance:
- Allow the stain to cure fully before use, generally 7-14 days.
- Apply a clear wood sealer like polyurethane for added protection. Reapply sealer every 2-3 years.
- Keep wood furniture covered or store indoors when not in use.
- Periodically clean stained cedar with a soft brush and mild cleaner. Avoid abrasives.
- Refinish faded cedar every 2-4 years to renew color and protection. Lightly sand and reapply stain.
Staining enhances the rich grain patterns and warm reddish-brown hues of cedar while providing protection from the elements. With proper preparation, application, and maintenance, a stained cedar surface will last for many years of enjoyment.

Frequently Asked Questions
What is the best stain color for cedar?
For outdoor cedar, transparent oil-based stains in natural wood tones work best to enhance the cedar’s natural coloring while allowing the grain to show through. Light to medium browns and reds are popular. For indoor cedar, water-based stains offer great color selection from natural wood hues to darker walnut and cherry shades.
How long does cedar staining last?
With proper prep and application, an oil-based stain on exterior cedar siding or furniture can last 2-4 years before maintenance is needed. Water-based stains on interior cedar may need light sanding and re-coating every 2-3 years. Durability depends on the quality of the stain, exposure to sun and moisture, and maintenance.
Should cedar be stained before or after construction?
It is best to pre-stain all cedar wood components before assembly and construction. This allows the stain to penetrate properly and makes it easier to achieve an even finish. Once assembled, it is difficult to stain interior surfaces and joints evenly.
Can you use the same stain for indoor and outdoor cedar?
It is best to use two separate stains formulated specifically for interior or exterior use. Outdoor oil-based stains provide more UV blockers, water repellency, and mold/mildew inhibitors while interior water-based stains offer lower VOCs and a wider variety of decorative colors.
How long should you let cedar dry before staining?
Freshly milled cedar needs 2-4 weeks of drying time outdoors before staining. The wood must be fully cured with a moisture content below 15%. Staining wet cedar can cause problems like peeling, cracking, and mold growth. Allow sufficient drying time for the best stain absorption.
Conclusion
Staining cedar wood provides long-lasting protection along with enhancing the wood’s natural beauty. To achieve a durable, quality finish, carefully prepare the surface, select the right stain type, apply using proper technique, and provide regular maintenance when needed. With the right approach to prep, application, and care, stained cedar lumber, siding, furniture and other items will retain their visual appeal and perform well for years of use.
