Enormous bond strength, even in the bathroom

This tape I have gained for gluing the tiles in our bathroom. Here I had already tried several other tapes and pads, all of which have surrendered sometime due to the moisture. So I was very curious to see whether this band competition would be able to hit, and finally would be able to fix my towel racks and hooks in the bathroom permanently.
Because as tape is also suitable for working outdoors, I used it for a hook bar on the wall of my garden shed.

The following must be observed during assembly:

The surfaces must be smooth, firm, clean, dry and free of grease and staubrei be (ie previously cleaned)
The tape should be at least 10 seconds forcefully pressed
Normally, you should then for 24 hours, the adhesive not burden in difficult places for safety's sake, even for 3 days

After that, the tape should really hold bombproof.
I classifies my towel rack in the bathroom as a "difficult" place (because of the high humidity) I have actually waited three days, and now after a week (with daily "shower session" that inevitably arise in a large family) keep the towel rail is still correct fixed (my tensile load for testing purposes does not change the really excellent grip).

The long-term test (also just outside, where even the sunlight to come) has the tape still exist, but stand today I am really convinced of the massive adhesive strength and dare to hope that I now finally a permanent solution for my tiles in the bathroom have found that does not require drilling.

CONCLUSION:
Very strong adhesive power, even in humid conditions, recommended previously to 100%
