Provide the old product label if available. A penetrating oil maintenance treatment is different from applying a film-forming deck paint. An existing incompatible coating may need separate preparation, so a new oil should not be selected from colour preference alone.
Furniture, foot traffic and coverings should return only when the selected product allows. Agree access to doors and other routes while the deck is unavailable. A maintenance plan should follow the actual finish and exposure rather than an invented universal recoating interval.
Dirt and surface contamination can affect the finish. Agree suitable ordinary cleaning as part of the preparation rather than assuming oil covers it. Structural deterioration, hazardous materials and repairs to unsound boards remain separate from a maintenance oiling task.
Apply the compatible oil according to its coverage and application instructions to the agreed prepared accessible deck surface. Scope limits: Compatible penetrating-finish maintenance on sound timber only. No structural repairs, hazardous stripping, waterproofing systems or guaranteed restoration of damaged boards.
