The smooth and firm bonding surfaces should be cleaned prior-rubbing alcohol or isopropanol. The optimum processing temperature is between 15 and 25 degrees. After pressing the tape both parts should be at least ten seconds pressed full surface vigorously. After the bond is at least 24 hours not be charged, but no load to dry (with a hook on the tiled wall I exonerate the bond here temporarily with adhesive tape).
My in accordance with these instructions so far in the bathroom and in the kitchen so attached hooks keep their (small) loads still quite good. A residue-free detachment, possibly again with the help of benzine, fresh is fairly simple and is more difficult the older the bond and of course, the greater the adhesive surface is.
