Varnishing and fitting fire doors in a Victorian house (part 2)

Tuesday, February 17, 2015 0 , , Permalink 1

In my last blog post I talked about choosing some lovely oak veneer fire doors and antique brass door furniture. I was a bit nervous about them being delivered because of their weight and the care that needed to be taken to stop them from warping.

They needed to be laid flat and the room couldn’t be too hot, too damp or too dry otherwise the moisture content of the doors would become unbalanced and they’d warp out of shape.

Wet plaster anywhere near untreated doors is an absolute no no. But I had to get some damp proofing done in the living room and have a ceiling in one of the bedrooms replastered at the same time – not ideal! I ended up clearing a space in the dining room where I could lay the three doors flat on the floor. I kept the central heating turned off, used a dehumidifier upstairs to reduce air moisture and kept the door to the living room closed.

Untreated doors need to be sealed as soon as possible after delivery. I had a couple of weeks to varnish them before they were fitted so I set up a space to work in the dining room.

I used Sikkens Cetol TSI Satin Plus in light oak to seal the doors. The manufacturer advised to not use water-based stains and varnishes, Danish oil products or wax because they might penetrate the glue and lift the veneer (de-lamination). I only had space to varnish one side at a time so the next night, once it was dry, my boyfriend helped me flip the door over so I could do the other side.

Sadly one of the original door frames had to be replaced because it was fitted out of alignment by the Victorian builders. Usually a door can be trimmed to suit the frame but when fitting fire doors there’s a limit to the amount that can taken off each edge. In this case the frame was so wonky that it wasn’t possible to accommodate the fire door. A local joiner did all this then fitted the doors.

The doors still need another two coats of varnish, and of course the rest of the house needs decorating around them, but overall I’m really pleased!

How to choose fire doors for a Victorian house (part 1)

When I bought my house the survey highlighted that fire doors weren’t installed. This was strange because the loft had previously been converted and a building regulations certificate had been issued. Fire doors are normally required to create a protected means of escape from a converted loft to the nearest exit so that if a fire starts in one of the adjoining rooms a person in the loft can get out.

The existing white panel doors looked tatty and had to be replaced anyway. In the end I decided to install fire doors now to avoid problems later when getting further alterations in the loft reassessed by the council.

Get advice about fire door regulations

Fire safety regulations were not something I’d ever considered in great detail before so I spent a lot of time reading up on technical guidance and emailing Newcastle City Council’s planning department for advice. I’ll not bore you with that detail here! If you want to find out more you should read Approved Document B on fire safety, BWF Certifire advice or start with general fire regulation guidance.

Upgrade original doors instead

None of my doors are original, but if you have genuine Victorian doors you might be able to upgrade them to fire doors using special intumescent paint and strips. When a closed door gets hot the intumescent coating expands to help seal in the fire and slow down its progress. Check with a specialist joiner or your local council’s planning department for more information.

Take inspiration from existing original features

Match up new fire doors to existing doors or get ideas from period features elsewhere in your house. The panels on the bay windows in my living room and front bedroom have simple flat panels with non-raised mouldings.

I chose an oak veneer 4-panel door (the Islington by Door Deals) because the flat panels and mouldings are a close match to my existing bay window panels and I loved the pattern of the grain.

Choose fire-rated door furniture

I couldn’t get the traditional porcelain door knobs I’d had my eye on because they weren’t fire resistant. It took me ages to decide on another style of knob (and I mean weeks!) but in the end I went for antique brass door knobs (Goodrich by Carlisle Brass) with a reeded design that mirrors the reeded moulding on my window recess. I don’t think anyone apart from me would ever notice this…

If you have door knobs rather than handles you’ll need to buy a longer latch so that there’s room to turn the handle without catching your knuckles on the frame. After some trial and error I went for the 127mm Altro Heavy Duty Tubular Latch in Florentine bronze.

Hinges also need to be fire resistant and you’ll need three 4-inch hinges for each fire door. I chose Florentine bronze hinges by Carlisle Brass.

Keep original frames if possible

Fire doors are normally installed in a new door frame which has a grove all the way round to hold a plastic (intumescant) strip which expands when hot to create a fire resistant seal. If you’ve got original door frames it might be possible to keep them and instead router a channel into the edges of the door to hold the intumescent strip.

I’ll explain more about fitting and varnishing the doors in part two – coming soon!
