That's a very common and valid concern! Splinters from wooden outdoor benches are not just painful; they can also lead to infections. Let's break down your question about whether the wood is treated or sanded smooth.
Generally, for commercial or high-quality outdoor wooden benches, the answer is ideally both.
Is the Wood Treated?
Yes, most wooden outdoor benches are made from "treated" wood. This doesn't directly relate to splinters but is crucial for longevity. Treatment involves infusing the wood with chemicals (like ACQ or copper azole) to protect it from rot, decay, and insect damage. This wood is often called "pressure-treated lumber." The treatment process itself doesn't make the wood smooth.
Is it Sanded Smooth?
This is the key to splinter prevention. A reputable manufacturer will sand the wood smooth as a critical final step in the production process. Sanding removes rough spots, sharp edges, and raised wood grains, creating a comfortable, splinter-resistant surface. You should be able to run your hand over a well-made bench and feel a smooth, even finish.
However, the reality can be different. Cheaper, mass-produced benches or public park benches that have suffered from weather exposure and lack of maintenance can become rough and splintery over time.
What You Can Do:
* For a New Bench: Always check the surface finish before buying. Run your hand along the seating area and armrests.
* For an Existing Rough Bench: You can lightly sand any rough areas with medium-grit sandpaper (like 120-grit) followed by a finer grit (220-grit) to smooth it out. Always apply a sealant or outdoor-rated wood oil afterwards to protect the newly exposed wood.
* A Great Alternative: Consider benches made from thermally modified wood or high-quality plastic lumber. These materials are inherently more splinter-resistant and require less maintenance.
In conclusion, a good wooden outdoor bench should be both treated for durability and sanded smooth for safety. Always inspect the finish, and don't hesitate to perform a little maintenance to ensure your outdoor seating is splinter-free.
