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: a gate does not swing, latch or sit as intended or outdoor timber looks weathered and needs a focused maintenance or repair decision. Causes: weather exposure and ordinary surface deterioration or an aged coating, stain or finish that needs preparation before maintenance.
Identify the previous coating where possible and show peeling, glossy or stained areas. Different finishes affect the preparation method. Unknown or suspect hazardous coatings are excluded; a sanding enquiry does not authorise stripping every old surface regardless of its composition.
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.
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.
