  • Dibond fixed with VHB Tape

    Posted by Matt Hards on April 30, 2009 at 3:08 pm

    Hi all,

    I have a fascia to fit tomorrow, which i had planned to use colour coded polytop screw to fix up.

    The fascia consists of 3mm gloss navy blue dibond 244cm x 51cm panels, 2 of them and a small 93.5cm x 51cm on the end. These will all butt up to each other to form a 581.5cm fascia. On top of this are butler finish 3mm dibond flat cut letters.

    My cunning plan is to now fix the fascia up with vhb foam trim tape (from Hexis) on to the new plywood/painted fascia. My thinking is that all the fixings will then be hidden, and create a nicer finish. Also the flat cut letters will be screwed right through the sign and into the plywood fascia and will take the brunt of the weight of the sign, with the tape holding down the edges. The smaller panel at the end, doesnt have any letters on though, so this will be relying on the tape alone.

    Basically i want your advice as to whether this is a good idea, or whether i should stick to the original plan of using colour coded screws to fix.

    Hope you can help

    Matt

    can’t see why it would be a problem, if the stand-offs for the letters screw right through then as you say, the main panel is supported.

    I fitted a fascia last week the same way but also glued the panels as well so I didnt need to put any screws in the fascia. The fascia I fitted was matt black so I masked the joins by 2-3mm and ran some black silicon down.

    They want more done now.

    you could always put a few spots of construction adhesive behind as well, that way the VHB tape will take care of the initial grab & should it ever give the adhesive will hold it. Use something like Sticks like Sh*t by evostick don’t use No more nails etc they dry hard & any movement causes them to brake off the substrates.

    looks like a go then 🙂 but what about the signel panel without any screws in of 51×93.5cm do you think this will be ok,its a fairly small panel, if i glue it as well. Also what is the longevity of the vhb tape, is it going to last as long as the sign

    i would think it’ll be fine Matt.

    as Kevin said, perhaps a few spots of decent glue to help it.

    Hi Matt, not to put a damper on the idea of using d/sided tape but the grip of the tape is only as good as the paint on the surface.

    If the the surface has not been rubbed down properly and the paint was put onto a gloss surface then there is no key between surface and paint.

    The tape will stick well to the paint but the paint may come away from the surface.

    Sanding down the paint where the tape will apply may help.

    I might be too late but just a word of warning when using grab adhesive on composite panels it can cause visible distortion to the face of the composite board ! Be careful what glue you use. . . test a bit first on a couple of scraps and leave overnight !
