Identify the door before starting
Check whether the door is timber, factory-primed fibreboard, laminate or an existing painted surface. Each can need a different preparation system. Older paint may contain hazardous pigments: get advice before abrasion if its history is uncertain. Fire doors, smoke seals and their hardware need particular care. Do not alter, remove coatings from or paint seals unless the door manufacturer's guidance permits it.
Create a manageable work area
Choose a time when the doorway can remain clear while the coating dries. Protect flooring and secure the door against accidental movement without obstructing an essential escape route. Keep children and pets away from wet surfaces. Only remove ordinary decorative handles if you can safely refit them; leave closers, fire hardware and unfamiliar mechanisms to someone competent. Store each screw set in a labelled container.
Prepare for adhesion and a flat finish
Clean hand grease from the handle area and the door edge, then rinse and dry as the cleaner directs. On a known safe coating, level small defects and create the key required by the new system without needlessly stripping sound paint. Remove dust and spot-prime bare areas where specified. Apply a small compatibility trial if the old coating or factory primer is uncertain.
Work in a planned sequence
Stir the paint and decant a manageable amount into a clean kettle. On a panelled door, complete manageable sections so the adjoining edges remain workable; avoid leaving heavy pools in moulded corners. Use the brush or roller recommended for the coating. Finish each area with light, consistent strokes, checking the lower edges for runs. Do not keep brushing paint once it has begun to set.
Give the finish time to develop
Follow the product's recoating interval rather than judging readiness by touch alone. Cool rooms and limited airflow can change practical drying conditions. Inspect the first dry coat under side light and correct suitable minor imperfections before the next coat. Keep painted edges from contacting stops until sufficiently dry, and allow curing time before routine cleaning. Record the product details so later touch-ups are a closer match.
Related questions
Do I have to take the door off its hinges?
Usually a conventional door can be painted in position if access and safe drying space allow. Removal can create handling risks and is inappropriate for unfamiliar fire-door arrangements without competent help.
Why does the paint feel dry but stick to the frame?
Touch drying happens before full hardening. Thick coats, unsuitable conditions or closing too soon can cause blocking. Follow the coating's guidance for closing doors, not only its touch-dry time.
