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.
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 proposed paint must be intended for the accepted timber deck application. Wall or trim paint should not be substituted because the colour matches. Product suitability and instructions guide the work, without implying a certified slip rating or specialist performance guarantee.
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.
