Show both intact and peeling areas. A new coat relies on suitable preparation and sound underlying material. Painting over loose film can leave the same weakness underneath, so the quote needs to distinguish ordinary preparation from extensive stripping or board repair.
Surface failure and deteriorated timber need different responses. A compatible repaint can address an accepted coating task on sound boards. Soft, split or unsupported timber needs separate review, and a fresh film must not be presented as restoration of structural condition.
The gaps and edges need to remain appropriate for the existing deck arrangement. Coating is not a way to fill movement gaps or conceal damaged boards. Show narrow, blocked or uneven gaps so the preparation can be reviewed before application.
Prepare the accepted sound surface and apply the agreed compatible deck-coating system in its required stages. Scope limits: Compatible film coatings on sound accessible timber only. No slip certification, hazardous stripping, structural repairs or waterproofing-system claims.
