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.
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.
Preparation and application need conditions allowed by the selected products. Rain and temperature can affect when the component is ready. The schedule should allow those stages without assuming exterior work can proceed continuously through unsuitable weather.
prepare and touch up a suitable local area. apply a compatible finish to an agreed sound surface. Limits: Complete ordinary accessible sound timber components only. No glazing work, structural rot reconstruction, hazardous stripping, waterproofing or high-access specialist work.
