Our fully finished fire doors arrive fully finished in a fixed colour or wood-effect surface, ready to install without the need to sand, prime, or paint them. You have plenty of stylistic options depending on your aesthetic preferences from oak effects to walnut. Constructed with fire-resistant materials, our fire doors are FD30-rated, meaning they will keep smoke and fire at bay for at least 30 minutes. This window of time allows building occupants to evacuate safely and could save lives in the most extreme cases. It also minimises the risk of serious, extensive property damage. At 44mm thick (9mm thicker than a standard internal door), our pre-finished fire doors offer solid sound insulation in addition to fire protection.

What is a fully finished fire door?
A fire door is designed to provide fire and smoke resistance for a given time. All of our pre-finished fire doors are FD30 rated, meaning they can withstand fire and smoke for a minimum of 30 minutes.
Being fully finished, also known as pre-finished, these fire doors are ready to hang without the need for painting or staining. Ideal for less mess and a quicker installation.
What are the benefits of pre-finished fire doors?
Fully finished fire doors are the most practical choice for people who need a fire door they can hang in their space quickly.
Pre Finished Fire Doors are Ideal for:
- Homeowners who are not DIY experts and don’t relish the prospect of spending the weekend with a sander or waiting for paint to dry.
- Property landlords who are managing renovation projects with tight turnaround times.
- Contractors handing over a construction project.
- Responsible persons in a commercial environment such as office managers.
Some of our customers love nothing more than putting a day or two aside to paint their door and getting their hands dirty. But if you’re not one of them, that’s okay. You don’t need to be, as our pre-finished and fully finished fire doors save you time and stress.
Can I paint a fully finished fire door?
You can, but we don’t recommend doing this. If you want to customise your fire door’s colour, our primed fire doors are the better option for you. The factory-applied base coat of primer is already in place, and you can paint these doors in whatever colour you like. You have complete creative control if this is the route you want to go down.
Painting over a finished surface requires due diligence and proper preparation:
- You need to lightly sand the entire surface before you begin and use a suitable primer that’s compatible with the door’s finish.
- You must also avoid applying too many topcoats of paint, as this could make the door too thick and impact its ability to open and close properly, which may prove critical in the event of a fire.
- Painting over the door hinges could cause the same potential problem.
- Avoid painting over the intumescent seals, as this could prevent them from expanding properly during a fire.
- You could inadvertently end up painting over the door’s permanent safety label, which must remain visible during inspections.
Where should fully finished fire doors go?
Pre-finished and fully finished fire doors are particularly well-suited to:
- Renovation projects with tight deadlines
- Rental property turnarounds between tenants
- New build developments
- Houses in Multiple Occupation (HMOs)
- Blocks of flats (i.e., entrance doors to individual flats and doors leading to communal stairwells, as fire doors are crucial in protecting escape routes and compartmentalising fires)
- Any door leading from a house into an attached garage
- Schools and commercial settings where contractors have limited time to fit doors
Whether you're an everyday homeowner, managing agent, or responsible person at a commercial premises, our pre-finished and fully finished fire doors are tailored to your needs.
