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.
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.
The timber needs to accept the proposed product in the way its instructions require. Glossy residue, uneven wear or previous treatment can change absorption. Photos support planning, but an on-site suitability check may still be needed before the application method is confirmed.
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.
