deck sanding can be appropriate when an accessible board, rail, gate fitting or timber surface shows wear, movement or a damaged finish. Review board condition, remaining thickness and coating suitability before agreeing a sanding method and the next finish.
Signs: outdoor timber looks weathered and needs a focused maintenance or repair decision or a gate does not swing, latch or sit as intended. Causes: loose compatible fixings or local timber wear or weather exposure and ordinary surface deterioration.
The final preparation should suit the selected oil or compatible coating. Decide that finish before the sanding scope is confirmed. Sanding, oiling and deck painting are separate tasks; list the required stages so exposed prepared timber has an agreed follow-on plan.
Sanding removes timber as well as surface material. Heavily worn, thin or damaged boards may not be suitable. The task concerns sound boards, and surface preparation must not be used to conceal rot or substitute for a separate deck repair assessment.
Prepare and sand accepted sound boards with appropriate abrasive stages and dust control, within the agreed accessible area. Limits: Sound ordinary accessible boards only. No structural restoration, rot concealment, hazardous coating removal, asbestos or specialist dust remediation.
