Wood benches can indeed develop splinters over time, especially when exposed to outdoor elements like rain, sun, and temperature fluctuations. At our outdoor bench factory, we take this concern very seriously. The answer to your question is a definitive yes—we sand and seal all edges thoroughly, but let me explain the precise steps we take to ensure a splinter-free experience.

First, during the initial wood selection, we only use kiln-dried, tight-grain hardwoods such as teak, cedar, or treated pine. This reduces the natural tendency for splintering. Once the bench is assembled, every edge—including the top, bottom, sides, and all cut ends—undergoes a multi-stage sanding process. We start with coarse 60-grit sandpaper to remove any rough fibers, then progress to 120-grit for smoothing, and finish with fine 220-grit to create a surface that feels polished to the touch. This step alone eliminates most potential splinter points.

Next is the sealing process. We apply a high-quality, UV-resistant outdoor wood sealer or marine-grade varnish specifically formulated to penetrate the wood fibers. The sealant is brushed on meticulously, with special attention to corners, crevices, and end grains where water and rot often begin. After the first coat dries, we lightly sand again with 320-grit to remove any raised grain, then apply a second coat. This double-sealing method creates a durable barrier that not only prevents splintering but also protects against moisture, mildew, and cracking.

To further guarantee quality, every bench from our factory individually passes a tactile inspection. Our technicians run their hands over all edges and surfaces to detect any remaining roughness, and any bench that fails is immediately sent back for re-sanding and resealing. We also provide customers with care instructions to maintain the seal over time, such as annual reapplication. So, while no outdoor wood product is entirely maintenance-free, our thorough sanding and sealing process dramatically reduces the risk of splinters, ensuring your comfort and safety for years to come.
