A practical exterior timber painting decision starts with the affected item, its condition and the surrounding materials. Prepare and paint the accepted accessible timber component with a compatible exterior system, protecting adjacent surfaces and operating clearances.
Signs: a local repair or prior coating needs preparation before a new finish is considered or the existing finish shows ordinary wear that may suit bounded maintenance. Causes: surface damage that needs preparation before finishing or incompatible or unknown prior finishes that need checking.
Show sheltered and exposed faces and provide any timber or product information. The coating needs to suit exterior use and the actual component. Ordinary painting does not provide waterproofing-system repairs or a guarantee against deterioration caused by an unresolved building issue.
Old paint condition and product history affect preparation. Show flaking, glossy and bare sections together. Hazardous coatings and extensive specialist stripping are excluded; a compatible system should be selected only after the accepted sound substrate is understood.
Prepare and paint the accepted accessible timber component with a compatible exterior system, protecting adjacent surfaces and operating clearances. Limits: Complete ordinary accessible sound timber components only. No glazing work, structural rot reconstruction, hazardous stripping, waterproofing or high-access specialist work.
