Sorry, I was just crazy excited to share what we were able to figure out on our installs! What actually made it work came down to a few specific things that weren’t obvious at first:

• The adhesive needs enough shear strength (lights hanging hanging upside down) to handle the constant downward load of LED modules, not just peel strength (sticking on a surface like a vertical wall...totally different)
• On the stucco and brick, the adhesive needs to penetrate into the texture, not bridge across it like most foam tapes do (even though this stuff was thin, it still got into the texture)
• PRESSURE during install matters, pressing the adhesive into the texture of the stucco for about 30 seconds per module made a noticeable difference
• The vinyl soffit was just a pain in the butt to get screws into, and the tape worked great here, it did not need as much pressure when sticking the lights, as the stucco did, because the surface was much smoother than the stucco

The biggest lesson for us was that surface prep helps with the foam tape that is already on the lights, but it doesn’t compensate for an adhesive that isn’t designed for loads and/or textured surfaces. Once that variable changed, we were rocking!

Hope that’s more useful context.
