    The sign you see in the photo is relatively heavy and keeps falling off after we have tried using a variety of industrial double sided tape options.

    When we initially removed the signs to install the window film, there seemed to be a clear silicone or caulk that was used to assist in keeping the signs from falling to begin with. Does anyone have a recommendation as to what we could use as an assist to the double sided tape?

    As an FYI, when the signs fall, the tape is sticking to the film. The problem seems to be the back of the sign more than anything else. TIA.

    I'm not sure, but I was always under the impression you were not allowed to put ADA signs on glass partitions. You hadfta go to the nearest solid wall

    those signs are best installed with VHB tape plus !00% silicone adhesive combination.
    edited to add: you can install ADA signage on glass partitions. still serves its wayfinding purpose, is still within acceptable distance from latch-side of door, and there's no difference between a glass panel and a wall panel when you're visually impaired.

    always use a 100% silicone adhesive in conjunction with your tape when installing these types of signs, the change in temperature from heating to air conditioning can cause the signs to buckle and pop off the wall, the silicone is flexible enough to hold them in place.

    Clean the back of the sign! If the tape is sticking to the wall, the sign is the source of failure. We did a bunch of 1/2" thick corian (fake granite) signs for a college library, I was terrified I'd break a window when we had to remove one from a partition just like that. Mounted with 2 rows of 3m clear VHB tape, you could grab 5' of it at lowes for double the cost from a distributor, but it's 'local'.

    I have installed signs like that on glass with 3M VHB tape (gray) and it holds up really well. Cleaning glass and back of sign is important. No need for silicone.

    You installed the signs to etchmark vinyl? I believe that is the problem. The window film should have been installed on the inside

    Important: the direction of the tape. Use vertical taping whenever possible instead of horizontal.
    Think about how gravity is pulling on these and the surface area/direction it is pulling against and it'll make sense.

    We also add the dab of silicone but we add some green tape as insurance for a day to let the VHB & silicone set up.

    E6000 or E6100 with VHB running vertical. E6000 is fairly permanent and more aggressive than silicone

    1. Client was adamant about having the film installed from the exterior.

    2. The tape sticks to the film (VISIUM Dusted Crystal) Best and least expensive cast vinyl dusted crystal you'll find on the market if you're a dealer. The problem is definitely the back of the sign.

    Those signs aren't heavy (comparatively).

    I wouldn't use any liquid adhesive (silicone, etc). It will often shrink slightly when curing and pucker the vinyl....then you'll have another problem on your hands. There's zero need for any liquid adhesive.

    Vertical strips of VHB tape are more than sufficient. Clean and scuff the back of the sign prior to applying.

    We usually install with standard black foam double sided tape, 1/16" thick and a few dollups of silicone for permanent bond. Also make sure to scuff backs of signs that do not have any texture to make sure you get a good bond, especially plastics. Sometimes those plastics have a release film that needs to be cleaned off with alcohol prior to install or assembly. You should not have any problem installing signs over vinyl films. We actually cut black vinyl pieces to match the shape of the sign to install first to hide the tape and adhesive on the back of the sign.
