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.
Board edges, stairs and boundaries around posts can need a different application approach from open surfaces. Photograph these details and identify inaccessible sections. The agreed area should be clear so the finished scope does not depend on an assumption that every face is reachable.
Cleaning and suitable ordinary preparation depend on the existing coating and selected system. Discuss any required sanding separately. Unknown hazardous coatings are excluded, and a broad promise to remove every old finish would exceed the accepted handyman scope.
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.
