Does VHB tape stick better on 3D prints if the surface is completely flat or roughed up?

I made a hook recently that I put up with VHB tape. It fell off around 2 weeks later (the hook come loose from the tape). It's just a hook for an empty backpack, so let's say it is under medium load. Every time I design something like this I wonder…
