  • VHB tape for fixing stainless letters to gloss painted wood?

    Posted by John Dorling on April 17, 2014 at 3:41 pm

    I have got a quote for some 2mm stainless letters, tallest letter 233mm high. The stroke width on some letters is not wide enough for brass locators which I would usually use. Do you think VHB tape (cut to the shape of the letter) would be a good enough fixing for these? I know the stuff is incredibly strong but they are going onto gloss painted wood, and I would ultimately have to rely on the paint, not the tape. Anyone got any experience with this?

    Thanks

    Ask yourself:
    1. Are there going to be people walking under these letters?
    2. Do you value your sleep at night?

    You have your answer.

    i’m with simon on this theres no way you can work out what grip the paint has on the surface under neath so no has to be the answer to this,if they fall/hit somebody your liable,unless you want to supply only and let the client fit with VHB tape.your call but id say no. 😕

    as has been said, only the grip of the paint on the wood will determine the bond regardless to how strong the tape is. also,

    whoever is cutting your stainless steel letters, ask them to solder threaded rods on the back.
    you press them up like you do when making normal locator templates.
    then just drill holes where the locator/rod hits.
    squirt in some liquid fixing resin and slide in the letter rods.
    you just leave the letters there and the liquid will solidify securing the letters very strong.

    these types of fixings are also ideal for rough-cast or sand stone walls where the surface is very uneven. the roads allow you to level all the letters without distorting them by fixing to an uneven surface.

    If the stroke on stainless letters is extremely thin then another option is to weld pins to the backs of the letters instead.

    Thanks for the replies. Pretty much what I was suspecting really but Rob how well do you think studs will work on a timber fascia? I always use that method for brick or stone but not used on timber before. What sort of glue would you recommend?

    Gosh, I’ll be the odd one out….

    The TALLEST letter is only a shade over 200mm, only 2mm thick, and with a thin stroke. That "monster" is going to weigh in at what? 60 grams? 80 grams?

    IMHO, it is very very unlikely that the paint will fail, and even in the 1 in 10000 chance that it does, an in the 1 in 10000 chance that somebody walks past in time for that wee thing to hit him topside of the head, and the 1 in 10 000 000 chance that this individual has a skull as thin as an over inflated balloon…….. Nope, I’ll "risk" it with the VHB 😀

    I understand and agree to an extent Gert. but regardless to weight, a sharp stainless steel letter falling from height and hitting someone could easily open their head or face leaving you with a damages claim against you and your company.
    further more, unless the wood and painting process is 100% correct. you could easily see paint pulp, peal, warp in under 24 months. no mater 2 years or 5 even, you WILL still be held liable in the UK.

    Also, i could be wrong but i dont think VHB is designed for a painted surface application in the first place mate.

    I have only ever used them on wood once. has to be over ten years ago now and the last i passed "they are still up! 😀
    i had them on built-up stainless letters and it wasnt thru choice, the letters came with the threaded rods as opposed to the metal locator stud type fixings.
    i am suggesting the rods because of how thin the stroke/leg of the letter is and how secure it will be long term.
    back then i did not know the best adhesive fixing so i used a 3M 2-part adhesive we keep in stock. i forget who told me now, but was assured "big-head fixing type adhesive was fine to use also. i had both in stock but opted for the 3M one.
