Application needs to follow the product’s coverage and handling instructions. More oil does not automatically mean better protection, and excess can affect the surface. Discuss the agreed area and product quantity so the work is planned around the actual deck rather than a guessed number of cans.
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.
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.
