That's a very valid concern, and it's one of the top questions people have when choosing outdoor furniture. The smoothness of the finish on a wooden outdoor bench is the single most important factor in preventing splinters. Let's break down what you need to know.
A high-quality wooden bench intended for outdoor use should have an exceptionally smooth finish straight from the manufacturer. This isn't just about feeling nice to the touch; it's a crucial safety and durability feature. The wood is typically sanded down with progressively finer grits of sandpaper, creating a surface that is uniform and free of rough patches or raised wood grain.
However, the true hero in this story is the protective finish applied after sanding. This is usually a sealant, such as a UV-resistant varnish, polyurethane, or a high-quality outdoor oil. This coating does two critical things:
1. It seals the wood fibers together, preventing them from lifting and forming splinters.
2. It creates a hard, protective shell that shields the wood from moisture and sun damage, which are the primary causes of wood deterioration and splintering over time.
When you're inspecting a bench, run your hand slowly along the surface, especially on the seat and armrests. It should feel consistently smooth with no catches on your skin. Pay close attention to end grains and joints, as these areas can be trickier to finish and are potential weak spots.
It's important to remember that no finish lasts forever. Exposure to sun, rain, and changing temperatures will eventually wear down the protective layer. To maintain that smooth, splinter-free surface, a regular maintenance schedule of light sanding and reapplication of sealant every one to two years is highly recommended. With proper care, your wooden bench can remain a beautiful and safe place to relax for many years.
