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.
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.
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.
Prepare and sand accepted sound boards with appropriate abrasive stages and dust control, within the agreed accessible area. Scope limits: Sound ordinary accessible boards only. No structural restoration, rot concealment, hazardous coating removal, asbestos or specialist dust remediation.
