What are the most effective ways to prevent splintering in composite wood landscape bar counters?

Composite wood has become a premier choice for landscape bar counters due to its durability and aesthetic appeal. However, without proper care, it remains susceptible to splintering from weather exposure and physical impact. Preventing this damage requires a multi-faceted approach that begins with selection and continues through consistent maintenance.

Start by choosing high-density composite wood materials specifically rated for outdoor use. These products contain higher resin content and UV stabilizers that inherently resist moisture penetration and solar degradation. Apply a specialized composite wood sealant within 30 days of installation, focusing on end grains and cut edges where moisture intrusion typically begins. Reapply sealant every 12-18 months depending on climate conditions, with more frequent applications in areas with high rainfall or intense sun exposure.

Implement protective measures such as using coasters under glasses and avoiding direct cutting on the surface. Install overhead protection like pergolas or umbrellas to reduce direct weather contact. For existing counters showing early splintering signs, gently sand affected areas with 120-grit sandpaper followed by 220-grit for smoothing before resealing. Consider adding protective edge trim to high-impact areas.

Regular cleaning using composite wood-specific cleaners prevents dirt accumulation that can accelerate surface deterioration. Avoid pressure washers which can force moisture into microscopic openings. During winter months or extreme weather, use protective covers specifically designed for outdoor bar counters. These comprehensive strategies will significantly reduce splintering while maintaining both the functionality and beauty of your composite wood landscape bar counter.
