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: loose compatible fixings or local timber wear or weather exposure and ordinary surface deterioration.
The abrasive sequence depends on the accepted timber, existing finish and intended next product. A single aggressive pass is not a universal solution. The quote should identify the preparation goal rather than promise removal of every deep mark at any cost to the boards.
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.
