The selected system may require more than one stage with drying between applications. Follow the product sequence instead of treating an extra thick coat as equivalent. Access and weather need to support those stages before scheduling is confirmed.
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.
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.
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.
