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.
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.
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.
