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.
The selected finish needs its specified time before painted surfaces are pressed together or cleaned. Discuss how the opening will be used during that period. Application completion alone should not be taken as permission for immediate full contact or normal washing.
Photograph glass, seals and mechanical fittings near the timber. Ordinary protection and careful application are different from removing glazing or modifying hardware systems. Specialist glass work and electrical security integration are excluded from the painting scope.
Prepare and paint the accepted accessible timber component with a compatible exterior system, protecting adjacent surfaces and operating clearances. Scope limits: Complete ordinary accessible sound timber components only. No glazing work, structural rot reconstruction, hazardous stripping, waterproofing or high-access specialist work.
