An existing glossy coating may require different preparation from a matt surface. Tell Fix Nik what product was used if known. A compatible coating system and finish should be agreed before buying materials solely to match an old colour label.
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.
Mark which runs and door surrounds are included rather than describing the whole room as trim work. Profiles, corners and access can affect preparation. An approximate length and photographs help distinguish a small refresh from a larger renovation repaint.
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.
