    Looking to renew the shop front sign (300mm high) by approximately 6m wide

    We were just thinking standard pine and then Sadolin Superdec to match the windows, any other suggestion? Looking for a traditional flat sign front.

    The fascia above is also timber but requires replacement and changing from grey to black so looking to do same time. This again is approximately 300mm high but a good 10m wide

    The roof will be renewed later this year hopefully

    If you are looking at pine then douglas fir is the most durable of the pines. Will you be using a sign writer or stick on letters?. A sign writer will be able to advise from experience. Marine ply?
    Marine Ply could be an option, my concern with that is how would you finish the edges neatly enough so that it doesn't look out of place?
    For the edges use a decorative beading fixed with waterproof PVA glue secured with panel pins to hold it whilst the glue dries.
    This standard ply in B&Q suggests it can be used for signage, fascias, soffits

    Would you use it?


    I was thinking with the free cutting service it would be ideal to get my 3 lengths of 300mm

    They don't seem to offer Marine Ply....

    I guess I could seal the edges anyway?

    Posted By: VictorianecoWould you use it?

    I'd certainly want to know more about it before I considered using it
    - Under 'Standard' they quote 'EN 13986:2004' but that doesn't tell you anything. They need to quote the details to know what the ply actually is made from and is suitable for.

    - At the bottom they display an FSC logo, but it is linked only to the cover page of their certificate, which says it applies to all products listed on the attached schedule. But the schedule isn't attached! So you have no idea about the origin of the timber in this product.

    They don't seem to offer Marine Ply....

    'Marine ply' is an obsolete standard, not used any more.
    I bought the b&q stuff as time is of the essence.

    Just trying to find out if sadolin superdec suitable to go straight on.

    The man in b&q said to use Thomson water sealer on the edges
    Thinking aloud, I think I'll go with some 2x1 PSE pinned around the perimeter with some d3 foaming glue in between...

    Quality and longevity are closely related to available budget, both in terms of materials and labour, for any given job. As such the solution for a five year fix is very different to a twenty year plus solution. Even that is again altered by willingness to maintain to a suitable standard.

    Materials from a diy shed , along with a “needed quick “ approach and little maintenance on an exposed elevation might if you’re lucky last 5 years , but be quick and cheap.

    Accoya, skilled joinery , decoration, signwriting and timely maintenance in the same postion could well last beyond your lifetime but be expensive initially and in terms of ongoing maintenance in comparison.

    So many variables as to make it hard to offer an opinion on the best way forward.
    And of course there is the appearance of the finished job which will vary according to the solution e.g. the difference between DIY stick on letters and professional sign writing - which will alter the perception given to the public and the image you wish to present.
    I can't seem to find sheet accoya it needs to be 300mm wide and 2400mm long

    Some timber merchants sell upto four different grades of plywood. Best go speak to one as they range in quality enormously.

    See grades here..

    I would avoid anything from the DIY sheds. I had some that claimed to be "WBP" but a sample delamination very quickly.

    Unfortunately prices have shot up in last 6 months
    Well known marine ply supplier in Bristol:

    Never bought marine ply from them myself but they were highly recommended to me for boat building (so BS1088, not the EN stuff they sell in building stores)

    Or there's plenty of folk selling marine ply on eBay.

    It ain't cheap...

    Edit to add: how about aluminium sheet?

    I can second the recommendation for Robbins
