ToggleWhy Seal Cedar Wood?
Cedar’s natural beauty ranges from amber tones to deep reds, but exposure to sun, rain, and moisture causes fading, cracking, and damage. A high-quality sealer:
- Blocks UV rays and moisture
- Prevents warping and splitting
- Enhances the wood’s color and grain
- Prolongs the wood’s life

How to Choose the Best Cedar Sealer
Not all sealers are created equal. The best sealer for cedar should:
- Deeply penetrate the wood, not just sit on the surface
- Be compatible with cedar’s natural oils
- Offer UV protection and mold resistance
- Preserve both color and structural integrity
Woodrich Brand Timber Oil meets all these criteria, delivering a rich finish and long-lasting protection.
How to Seal Cedar for Outdoor Use
Step-by-step process:
- Prep the surface – Clean the wood using a specialized cleaner or mild soap. Sand lightly if needed.
- Choose your application tool – Use a brush, roller, or sprayer.
- Apply with the grain – Evenly coat the wood, wiping excess to prevent blotches.
