That's a very common and valid concern! Splinters from wooden benches are not just painful; they can lead to infections. Let's break down whether treated wood is the better choice for avoiding them.
The short answer is: Not necessarily for splinter prevention alone. Wood treatment is primarily about rot and insect resistance, not surface smoothness. The treatment process involves forcing preservatives (like ACQ or micronized copper) into the wood's cells to protect its *core*. However, the surface texture is still raw wood, which can weather and splinter over time just like untreated wood.
The real key to a splinter-free bench isn't the treatment type, but the wood species and maintenance.
* Wood Choice: Denser hardwoods like teak, ipe, or cedar naturally resist splintering better than softer woods like pine, even when the pine is treated.
* The Maintenance Factor: This is crucial. Any wood—treated or not—becomes rough when exposed to sun, rain, and changing temperatures. The grain raises, and tiny splinters form.
Your Best Action Plan for Safety:
1. Regular Sanding: Lightly sand your bench annually with medium-grit sandpaper to smooth raised grain. This is the single most effective step.
2. Apply a Protective Finish: After sanding, use a high-quality exterior sealant, oil (like teak oil), or water-repellent stain. This seals the surface, minimizes moisture absorption that causes grain raising, and protects the wood.
3. Inspect Regularly: Run your hand over the bench at the start of the season to feel for rough spots.
So, while treated wood is excellent for longevity against rot, don't rely on the treatment to prevent splinters. Choose a durable wood species and commit to simple, yearly maintenance. A well-sanded and sealed bench, whether treated or not, will be far safer and more comfortable for years to come. Enjoy your outdoor space with peace of mind
