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.
Share the exact proposed oil, timber information and previous treatment before purchase. Similar product names can describe different systems. The quote should identify the selected compatible treatment; substituting a different can on the day can change the preparation and application requirements.
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.
