Wood vs. Composite: Power Washing Tips for Each Deck Type
A deck is often the centerpiece of outdoor living, where friends gather, meals are shared, and summer evenings stretch late into the night. But with all that traffic and exposure to the elements, decks—whether wood or composite—need regular cleaning to stay safe and beautiful. That’s where choosing the right approach to power washing becomes critical. If you’re considering professional help, trusted companies like Wilhelm Painting & Power Washing offer reliable power washing services in Massillon OH as part of their broader cleaning services. Knowing how to treat your specific deck material can make all the difference in maintaining its lifespan and appearance.
Understanding the Difference: Wood vs. Composite
Before we dive into techniques, it helps to understand why these two deck materials need distinct care. Wood is natural, porous, and highly susceptible to moisture, mildew, and rot. It requires gentle but effective cleaning to avoid damaging the grain. Composite decking, on the other hand, is made of a blend of wood fibers and plastic, making it more resistant to mold and rot but still vulnerable to staining and surface wear if handled improperly.
Both types benefit from power washing, but the method and tools should be adjusted to match the material. Using the same settings and solutions for both could lead to discoloration, splintering, or even voided warranties.
Power Washing Tips for Wood Decks
Wood decks require extra attention because of their organic structure. Too much pressure can gouge the surface or raise the wood fibers, leading to splinters.
Use the right pressure: Stick to a setting between 500 and 1,200 PSI (pounds per square inch). Anything higher risks damage.
Select the right nozzle: A 40-degree fan tip spreads water out evenly and prevents cutting into the wood.
Work with the grain: Always spray in the same direction as the wood grain to minimize streaking and damage.
Follow up with sealant: After power washing, let the deck dry for at least 48 hours before applying a sealant. This step protects the wood from absorbing moisture in the future.
Think of wood as a sponge—it can be refreshed beautifully with the right care, but it’s easy to scar if handled too harshly.
Power Washing Tips for Composite Decks
Composite decking may be marketed as “low maintenance,” but it still needs care to prevent staining, mold growth, or buildup of dirt and pollen. Unlike wood, composite surfaces can develop stubborn grime if left unattended.
Lower pressure is best: Stick with a setting of 1,500 PSI or lower. Even though composites are durable, high pressure can still damage the surface.
Use a soft brush: A gentle scrubbing motion during or after power washing helps loosen dirt from textured surfaces.
Choose the right cleaner: Many manufacturers recommend non-chlorine bleach or specialized composite deck cleaners. Harsh chemicals can fade or weaken the surface.
Rinse thoroughly: Leaving cleaner residue behind can create streaks or discoloration, especially on darker boards.
Composite decks don’t need sealing like wood, but consistent cleaning will keep them looking sharp for years.
When to Call in the Pros
While DIY power washing can be rewarding, hiring professionals ensures your deck gets the right treatment without risk of damage. Specialists like Wilhelm Painting & Power Washing bring the right equipment and knowledge to tailor their approach to your specific deck type. They understand that one size doesn’t fit all when it comes to deck care, which is why their services extend beyond just power washing to comprehensive cleaning solutions.
Case Study: A Tale of Two Decks
One Massillon homeowner had a cedar wood deck and a smaller composite deck in the backyard. After trying DIY cleaning, they noticed streaking on the composite boards and rough patches on the cedar planks. They called in professionals, who adjusted the PSI for each surface and used different cleaners. The result? Both decks looked refreshed and damage-free, with the homeowner vowing to leave the job to the pros in the future.
Final Thoughts
Your deck is an investment, and the way you maintain it matters. Wood decks need careful handling and sealing, while composite decks require the right cleaners and lower pressure settings.
