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: an accessible board, rail, gate fitting or timber surface shows wear, movement or a damaged finish or outdoor timber looks weathered and needs a focused maintenance or repair decision. Causes: an aged coating, stain or finish that needs preparation before maintenance or weather exposure and ordinary surface deterioration.
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.
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.
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.
