What are the best wood-sanding grit sequences for eucalyptus outdoor armchair armrests?

When refinishing eucalyptus outdoor armchair armrests, selecting the right sanding grit sequence is crucial for achieving a smooth, long-lasting finish. Eucalyptus is a dense hardwood, so starting with a coarse grit (80-100) helps remove old finishes and imperfections. Follow with a medium grit (120-150) to smooth the surface, and finish with a fine grit (180-220) for a polished feel. Always sand along the grain to avoid scratches. For extra durability, consider sealing with outdoor-grade oil or varnish after sanding. This method ensures your armrests remain weather-resistant and comfortable for years.
