A loose board or crumbling edge should not be hidden beneath another coat. Show splits, movement and moisture damage separately. Suitable trim repair may be discussed through the relevant repair service before any finishing work is planned.
Painting to a natural break may provide a clearer finish boundary than touching up several scattered spots. Whether that is useful depends on condition and matching expectations. Any extension of the paint area should be agreed before work begins.
Grooves and moulded corners can retain loose paint or dirt that affects adhesion. The profile should be visible in the enquiry photos. Preparation must stay within suitable non-hazardous methods and does not imply stripping unknown old coatings.
The agreed service covers small interior trim preparation and recoating after substrate suitability review. Exclusions: Structural timber repair, hazardous coating removal, external window restoration, large renovation repaint.
