The key with this, as with any other adhesive-based product, is proper substrate preparation. It needs to not only be clean, but free of any oily residues. Don't wipe it with regular household cleaners, as they tend to leave behind residue. Your final pass should be with 99% or higher isopropyl alcohol. The standard household rubbing alcohol is usually 70-90% alcohol, and the rest is mostly water. This works too, but 99% is better.
Also, ideal application temperature is 68-104F (20-40F). Below these temperatures, the adhesive doesn't like to bond well to the substrate. Adding a little pressure and heat will always help the bond.
If you are bonding to a very slick surface (low surface energy) such as a powder coated steel or polyethylene, you may need a different VHB product. We have used 4952 in these applications with good success, which is specifically designed for LSE substrates.
1) You have to prep both surfaces. Clean with plain old isopropyl alcohol. If possible, rough up the surface where you will put the tape with something abrasive (before using the isopropyl alcohol).
2) The first 72 hours this stuff wants to be close to body temperature. I put mine on the top of the clothes dryer or something similar. If it were something big, I have halogen shop lights I could use to raise the temp enough to "cure" it. A hair-dryer might work in a pinch, but that's a lot of trouble.
3) Pressure helps, but pressure by itself may not get it done. I used regular hand clamps with thin books/boards under the clamps to make sure I didn't damage/scratch/bend the object I was taping.
Once it's stuck (past the 72 hour curing period), temperature doesn't seem to make any difference at all. Don't expect to be able to get this stuff off once it's cured -- not without pulling off pieces of the material that it is stuck to.
Here is my prep procedure:
Clean both surfaces with soap and water. Dry with a lint free cloth. Next I used 90% alcohol to clean any residue left over. I next used a 3m adhesive promoter on each contact surface. The promoter makes a huge difference in the bonding. Place the Vhb tape on the surface to be installed. Leave the protective backing on the tape until you have it in the exact spot. I then attached the splitter by clamps on each end and 1 screw in the middle. Slowly pull the tape backing. Be very certain you have it in the correct position before you pull the backing off the tape. Press on the part along where the tape is attached. Done. It ain't coming off easily. I totally trust that it will not come off.
I wiped down the window frame and cut the tape to fit the mounting brackets. I applied the tape to the brackets and heated it with a hair dryer. Then, I applied the brackets to the inside of the frame. The next day, I put up the first "test" blind and it held. We came back the next day and it was still up so I went ahead with the rest of them. An hour later, all of the blinds were installed. It has been almost a year since installation and we haven't had a single incident. They are all still holding well with regular use.
I honestly think that if I had a choice between mounting the blinds with screws and mounting them with this VHB tape, I would do the tape again. It was that easy! I can't wait to find more applications for this amazing tape.
