Cedar Deck Board Benefits (5 Proven Wood Processing Tips)

Building a deck is a significant investment, and choosing the right materials is crucial. Cedar deck boards offer numerous advantages, making them a popular choice among homeowners and contractors alike. However, understanding how to properly process and maintain cedar is key to maximizing its lifespan and beauty. I’ll walk you through the benefits and share five proven wood processing tips to ensure your cedar deck stands the test of time.

Why Choose Cedar for Your Deck?

Cedar is a naturally durable and beautiful wood, but let’s delve into the specifics of why it excels as a decking material. I remember a project in Oregon where we used locally sourced Western Red Cedar for a massive wrap-around deck. The client loved the natural look and the fact that it required minimal upkeep.

Natural Resistance to Decay and Insects: Cedar contains natural oils that act as preservatives, making it resistant to rot, decay, and insect infestation. This inherent resistance significantly reduces the need for chemical treatments, making cedar an environmentally friendly choice. I’ve seen decks built with pressure-treated lumber succumb to rot in a few years, while cedar decks, properly maintained, can last for decades.
Dimensional Stability: Cedar is less prone to warping, twisting, and shrinking compared to other wood species. This stability ensures a smoother, more even deck surface over time. The dimensional stability of cedar is partly due to its low density and uniform cell structure. I’ve noticed this firsthand when comparing cedar to pine; cedar holds its shape much better.
Aesthetic Appeal: Cedar boasts a rich, warm color and a distinctive grain pattern that adds natural beauty to any outdoor space. Its natural hues range from light amber to deep reddish-brown, and it can be stained or sealed to further enhance its appearance. I appreciate the natural beauty of cedar, and often recommend letting it weather naturally to a silver-gray patina.
Workability: Cedar is relatively soft and easy to work with, making it a favorite among carpenters. It cuts cleanly, accepts nails and screws readily, and can be easily shaped and molded. I’ve found that using sharp tools is essential when working with cedar to avoid tear-out and ensure clean cuts.
Environmental Friendliness: As a renewable resource, cedar is an environmentally responsible choice for decking. Sustainable harvesting practices ensure that cedar forests are managed for long-term health and productivity. I always advocate for sourcing cedar from certified sustainable sources to minimize environmental impact.

Tip #1: Proper Cedar Selection and Grading

Choosing the right cedar for your deck is the first and most critical step. Not all cedar is created equal. Different grades offer varying levels of quality and appearance. I’ve learned this the hard way, having once used a lower grade cedar for a project and regretted it later when knots started popping out.

Understand Cedar Grades: Cedar is typically graded based on the number and size of knots, blemishes, and other imperfections. Common grades include Clear Heart, A Clear, Select Knotty, and Construction Common. Clear Heart is the highest grade, offering the fewest imperfections and the most uniform appearance. Select Knotty allows for some knots but is still structurally sound. Construction Common is the lowest grade and is typically used for less visible components.
Inspect for Defects: Before purchasing cedar, carefully inspect each board for defects such as large knots, cracks, splits, and rot. Avoid boards with excessive imperfections, as they can compromise the structural integrity and appearance of your deck. I always take the time to hand-pick my cedar, ensuring that each board meets my standards.
Consider Moisture Content: The moisture content of cedar can significantly impact its stability and performance. Look for kiln-dried cedar with a moisture content of around 12-15%. This will help minimize warping and shrinking after installation. I use a moisture meter to check the moisture content of cedar before starting any project.
Source from Reputable Suppliers: Purchase cedar from reputable lumberyards or suppliers who specialize in cedar products. These suppliers are more likely to offer high-quality cedar and provide expert advice on selection and installation. I’ve built relationships with local mills that provide me with consistently high-quality cedar at competitive prices.
Budget Accordingly: Higher grades of cedar will be more expensive, but the investment is often worth it in terms of aesthetics, durability, and longevity. Factor the cost of cedar into your overall deck budget and choose a grade that meets your needs and budget.

Takeaway: Selecting the right grade of cedar and inspecting for defects are crucial for ensuring the longevity and appearance of your deck. Always choose kiln-dried cedar from reputable suppliers.

Tip #2: Acclimation and Storage of Cedar Deck Boards

Once you’ve selected your cedar, proper acclimation and storage are essential to prevent warping, twisting, and other issues. I’ve seen entire stacks of lumber ruined due to improper storage, a costly mistake I learned from early in my career.

Acclimation Period: Allow cedar deck boards to acclimate to the local climate for at least one week before installation. This allows the wood to adjust to the local humidity and temperature, minimizing the risk of warping or shrinking after installation. I typically spread the boards out in the area where they will be installed, allowing for good air circulation.
Proper Stacking: Stack cedar deck boards flat on a level surface, using stickers (thin strips of wood) to separate each layer. This allows for air circulation and prevents moisture from becoming trapped between the boards. I use 1×2 inch stickers spaced about 2 feet apart to ensure adequate airflow.
Protect from the Elements: Store cedar deck boards in a dry, well-ventilated area away from direct sunlight and rain. Covering the stack with a tarp can provide additional protection from the elements. I prefer to store cedar in a garage or shed to protect it from extreme weather conditions.
Avoid Direct Contact with the Ground: Do not store cedar deck boards directly on the ground, as this can lead to moisture absorption and rot. Use pallets or other supports to elevate the stack off the ground. I always make sure there’s at least 6 inches of clearance between the ground and the bottom layer of boards.
Monitor Moisture Levels: Regularly check the moisture content of the cedar deck boards during the acclimation period. Use a moisture meter to ensure that the boards are within the recommended range of 12-15% before installation. If the moisture content is too high, allow the boards to acclimate for a longer period.

Takeaway: Proper acclimation and storage are crucial for preventing warping and ensuring the stability of your cedar deck. Always allow cedar to acclimate to the local climate and store it in a dry, well-ventilated area.

Tip #3: Precision Cutting and Milling Techniques

Accurate cutting and milling are essential for achieving a professional-looking cedar deck. Using the right tools and techniques will ensure clean, precise cuts and prevent splintering or tear-out. I’ve spent countless hours perfecting my cutting and milling skills, and I’m always striving to improve my techniques.

Sharp Tools are Key: Use sharp, high-quality saw blades and router bits to ensure clean, precise cuts. Dull tools can tear the wood fibers and leave a rough, uneven surface. I sharpen my saw blades regularly and replace them when they become too dull to sharpen effectively.
Use a Miter Saw: A miter saw is ideal for making accurate crosscuts on cedar deck boards. Use a fine-tooth blade designed for cutting hardwoods to minimize splintering. I prefer a miter saw with a laser guide for even greater accuracy.
Router for Edge Profiling: A router can be used to create decorative edges on cedar deck boards. Use a router bit with a bearing guide to follow the edge of the board and create a consistent profile. I often use a round-over bit to soften the edges of deck boards for a more comfortable feel.
Pre-Drilling Pilot Holes: Pre-drilling pilot holes before driving screws or nails into cedar deck boards will prevent splitting and ensure a stronger connection. Use a drill bit that is slightly smaller than the diameter of the screw or nail. I always pre-drill pilot holes, especially when working near the ends of boards.
Sanding for a Smooth Finish: Sand cedar deck boards after cutting and milling to remove any rough edges or imperfections. Use a fine-grit sandpaper (120-220 grit) and sand in the direction of the grain. I use a random orbital sander for larger surfaces and hand-sand for intricate details.

Takeaway: Precision cutting and milling are essential for achieving a professional-looking cedar deck. Use sharp tools, pre-drill pilot holes, and sand for a smooth finish.

Tip #4: Proper Fastening and Installation Methods

The way you fasten and install cedar deck boards will significantly impact their longevity and performance. Using the right fasteners and installation techniques will prevent warping, cupping, and other issues. I’ve learned that investing in high-quality fasteners is well worth the cost, as they will last longer and provide a more secure connection.

Use Stainless Steel Fasteners: Stainless steel screws or nails are the best choice for fastening cedar deck boards. Stainless steel is highly resistant to corrosion and will not react with the natural oils in cedar. I always use stainless steel fasteners, even though they are more expensive than galvanized fasteners.
Spacing Between Boards: Leave a small gap (approximately 1/8 inch) between cedar deck boards to allow for expansion and contraction. This will prevent the boards from buckling or cupping due to changes in temperature and humidity. I use a spacer tool to ensure consistent spacing between boards.
Staggered Seams: Stagger the seams of cedar deck boards to create a more visually appealing and structurally sound deck. Avoid lining up seams in adjacent rows, as this can create a weak point in the deck. I always plan my layout carefully to ensure that the seams are staggered effectively.
Proper Joist Spacing: The spacing of deck joists will impact the stability and strength of your cedar deck. Follow local building codes and manufacturer recommendations for joist spacing. I typically use 16-inch on-center joist spacing for cedar decks.
Hidden Fastening Systems: Consider using a hidden fastening system to create a clean, seamless deck surface. Hidden fasteners attach the deck boards from underneath, eliminating the need for visible screws or nails. I’ve used several hidden fastening systems and have been very impressed with the results.

Takeaway: Proper fastening and installation are crucial for preventing warping and ensuring the longevity of your cedar deck. Always use stainless steel fasteners, leave adequate spacing between boards, and follow proper joist spacing guidelines.

Tip #5: Sealing, Staining, and Ongoing Maintenance

Protecting your cedar deck with a sealant or stain and performing regular maintenance will significantly extend its lifespan and maintain its beauty. I’ve seen decks that were properly maintained last for decades, while neglected decks can deteriorate in just a few years.

Choose the Right Finish: Select a sealant or stain that is specifically designed for cedar decking. Look for products that contain UV inhibitors to protect the wood from sun damage. I prefer oil-based sealants, as they penetrate the wood and provide long-lasting protection.
Clean Before Applying Finish: Before applying any sealant or stain, thoroughly clean the cedar deck with a deck cleaner and a stiff brush. This will remove any dirt, mildew, or other contaminants that can prevent the finish from adhering properly. I always power-wash the deck before applying a finish, but be careful not to use too much pressure, as this can damage the wood.
Apply Thin, Even Coats: Apply the sealant or stain in thin, even coats, following the manufacturer’s instructions. Avoid applying too much finish, as this can lead to a sticky or uneven surface. I use a brush or a paint pad to apply the finish, working in the direction of the grain.
Regular Cleaning: Clean your cedar deck regularly to remove dirt, leaves, and other debris. Use a mild soap and water solution and a soft brush. Avoid using harsh chemicals or abrasive cleaners, as these can damage the wood. I typically clean my deck every few months to keep it looking its best.
Annual Inspection: Inspect your cedar deck annually for signs of damage, such as cracks, splits, or rot. Repair any damage promptly to prevent it from worsening. I always check for loose screws or nails and replace them as needed.

Takeaway: Sealing, staining, and regular maintenance are essential for extending the lifespan and maintaining the beauty of your cedar deck. Choose the right finish, clean regularly, and inspect for damage annually.
