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 an accessible board, rail, gate fitting or timber surface shows wear, movement or a damaged finish. Causes: weather exposure and ordinary surface deterioration or loose compatible fixings or local timber wear.
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.
If the coating history or material condition raises a hazardous-material concern, ordinary sanding should not proceed on an assumption. Share existing product records where available. Specialist testing or removal is outside the scope and must not be replaced by a disclaimer after disturbance.
repair a suitable local component. prepare and maintain sound accessible timber with a compatible finish. Limits: Sound ordinary accessible boards only. No structural restoration, rot concealment, hazardous coating removal, asbestos or specialist dust remediation.
