Exposed edges and ordinary joints need an agreed preparation boundary. Painting cannot reconstruct rotten timber or correct structural movement. If deterioration appears during preparation, discuss suitable separate work before applying a finish that could conceal the condition.
A painted door or window component still needs suitable movement and contact clearances. Excess paint build-up can affect operation. Agree which accessible faces can be coated and how they will remain separated while drying, without treating painting as a substitute for alignment repair.
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. Scope limits: Complete ordinary accessible sound timber components only. No glazing work, structural rot reconstruction, hazardous stripping, waterproofing or high-access specialist work.
