White Fire Doors

A white fire door lets a certified leaf disappear into painted joinery instead of announcing itself. Most are supplied primed, ready for two topcoats on site, and some arrive fully finished. Either way the fire rating belongs to the tested assembly, not the colour.

Painting a fire door safely

Only use a coating the manufacturer permits, keep it off the intumescent seals, and never strip or sand back to bare core. Complete the installation with fire rated hinges, intumescent strips and smoke seals and a door closer where self-closing is required.

Pick the rating in FD30 or FD60, and choose solid or vision panel in solid fire doors and glazed fire doors. Non-rated equivalents are in internal white primed doors.

Why white is the most specified fire door finish

A white fire door does two jobs at once: it meets the certification requirement on a hall, stairwell, garage or integral doorway, and it disappears into the standard white trim of a British hallway so the door does not announce itself as a fire door. Most are supplied white primed, ready for two coats of your own topcoat, which lets the finish be matched exactly to the architrave and skirting. Fully finished white options remove the decorating stage altogether.

Primed or fully finished

Primed leaves are cheaper and give a perfect colour match to existing woodwork, but they must be sealed on all six faces, including the top and bottom edges, before the door goes into service. Skipping the edges is the single most common cause of a leaf taking up moisture and sticking. Fully finished leaves arrive with a factory coating that is harder and more even than anything achievable on site. Our guide to pre-finished, unfinished and primed doors sets out the trade-off.

Getting the whole door set right

A certified leaf is only certified when it is hung with the right frame and ironmongery: fire rated hinges, intumescent strips and pads, a controlled door closer where self-closing is required, and a consistent gap around the leaf. Read the fire door guide and FD30 vs FD60 to confirm the rating you need, then browse FD30 and FD60.
