That's a great question, and a very common concern! The short answer is yes, wooden outdoor benches can become prone to splintering over time—but it's not an inevitable fate. With the right choices and care, you can enjoy their natural beauty for years without the worry.
The primary culprit behind splintering is weather exposure. The constant cycle of sun, rain, and temperature changes causes wood to expand and contract. This stresses the fibers, leading to cracks, warping, and eventually, those raised, sharp splinters. Untreated or low-quality wood is especially vulnerable.
Here’s the good news: You have significant control. Start by choosing the right wood. Dense, durable hardwoods like teak, ipe, or cedar have natural oils that resist moisture and decay, making them far less likely to splinter quickly compared to softer woods like pine. Look for benches made from pressure-treated lumber, which is infused with preservatives to withstand the elements.
Your most powerful tool is proactive maintenance. Applying a high-quality sealant, UV-protective oil, or outdoor-rated wood stain every one to two years creates a protective barrier. This shield repels water, blocks damaging UV rays, and keeps the wood stable. Regular cleaning to remove dirt and mildew also prevents moisture from being trapped against the surface.
If a splinter does appear, don't ignore it. Lightly sand the area with fine-grit sandpaper, following the wood grain. Always re-seal the sanded spot to protect the newly exposed wood. With this simple, consistent care, your wooden bench will develop a graceful, weathered patina rather than a rough, splintered surface, allowing you to relax in style and comfort for seasons to come.
