    I remember the Binns' asking you to give them a quote for restoring the coach. If you're able to share a copy of your report, that would be really helpful to us.

    Our latest advice on the buffer beams has been to avoid using oak and go with either sapele or iroko. I think we're likely to go with iroko.

    Well, the buffer beams are now fixed. We went for iroko in the end, with a lot of help on the woodwork from the Blyth Tall Ship Project, where one of our volunteers also volunteers.

    We're now planning for re-canvassing the roof. Having only worked with Mark 1 coaches, this is new to us.

    I've seen the information on Bluebell Railway's website and the LMSCA's excellent YouTube video, as well as LNERCA's alternative approach.

    What I'm not clear on is once the canvas is fixed, what treatment should go on top.

    I've seen conflicting information on this, so any suggestions would be appreciated.

    HI Micheal,
    Are you on the yahoo group Rail C as that is the best place to ask your questions.

    "What I'm not clear on is once the canvas is fixed, what treatment should go on top"

    There is no correct answer. Originally White lead paste was used which is why most older canvas roofed coaches had white roofs. Look in the NRM and many still have this. Royal saloons etc often had another coat applied to make it white again, but this is no longer available in Britain due to the lead (possibly the National Trust can still get it for old buildings)

    I have investigated this myself for my own project in that I am at the stage were I have now stuck the proofed cotton canvas down using the Canvas roof bonding compound (from TR Williamsons). Some groups have just then painted it with ordinary paint but I am not convinced that this is a good idea as it just makes it look nice but with no real waterproofing, so after investigating it I will go with one of two options (partly depends on price):-

    1 I am told TR Williamsons may have a product which is for the job (not sure, not spoken to them yet about this), but I am led to believe it was used by the Llangollen for the Didcot Railmotor project. (possibly it is the same anyway as option 2 see below)

    2 There is a product called Acrylic Roof sealant, which has fibres in it. There are various brands of this Flexacryl, Cromapol, Acrypol, Wickes also have their own brand version etc. It is easily available in most places in Black or Grey, (they don't usually stock it in white, although it is made) but I want my roof to be white so I will go for this version from tool station (called Flag Roofix 20/10 which you can get in black, grey or white )
    https://www.toolstation.com/shop/p23070?table=no

    It is actually made in the UK, not used it yet but I have used the Flexacryl on my house roof. You can see a video here to get the idea how it is used . There is also many other such videos for competing versions.

    You need to be careful there are various products which are similar but bitumen based and often they are on the same shelf in the shop. I am not sure I would go them them but it is your choice.

    In addition I believe the LNER coach association have used some other products here http://web.archive.org/web/20110727041705/http://www.lnerca.org/roof.htm
    but dont know much about these products so you would need to speak to them or the manufacturer

    So in conclusion it is up to you to decide but hope this might help

    We've just started using flexacryl on a couple of wagon roofs after frustrating leaks from when we used another product, will report back after it's rained a bit!

    Decadex, that LNERCA use is a water borne polymer that cures to a synthetic rubber, I suspect it is not dissimilar to the Flexacryl but without the fibres. We have found it performs well on roof canvases.

    I'd be interested to know how this lasts on a wagon roof. Most of ours have shed roofing felt on them because it's low maintenance and lasts a good few years, but when I eventually get round to fixing my SR van I am not sure if roofing felt will work due to the way the canvas attaches on these. So I might do a 'proper' job; the problem I have is I don't have time to look after a roof canvass properly and repaint it every year or two. Every 10 years I could probably cope with!

    Of interest, does use of synthetic products produce any of the bodywork issues asscociated with vinyl wraps?

    No. We also use a stretchy bandage like material from the same source to protect the wooden gutter mouldings so they effectively have their own mini canvas, which stops them from rotting.

    Thanks, that's really helpful. It gives us a few options. Does this type of finish need to be painted over or is it just applied then left?
