## Questions & Answers

**Q: Can this be used to seal a bathtub?**
A: I am not sure in what specific way you are referring.  It could be used effectively when installing a new tub into its alcove. It can also be used in some drain situations. It would not be useful for a hole or faucet leak.  If you are referring to the area around the top of the tub where it meets the wall, I would caulk using 100% silicone.

**Q: can this be used for installing glass panels to aluminium greenhouse frame?**
A: The tape will form a watertight and airtight seal between the glass and aluminum frame but it will not be a sufficient fastener.  Butyl tape is a pressure-sensitive tape, not a super sticky fastening tape. You will still need glass fasteners.  Contractors use butyl tape before screwing windows to houses. It provides an excellent weather tight seal.

**Q: can i use this to seal aroumd my sink**
A: It will work great as a seal that you set your sink into.  Remove your sink. Form the putty tape around the perimeter opening. Set your sink into the opening with the lip over the tape. cut off the excess. This will work just like putty but easier. It will not work like caulk after you have installed the sink.

**Q: Is this stuff supposed to be super sticky when it arrives? Do you need to heat it up to make it sticky or something? Mine seems really dry and not eve**
A: Hello, The butyl tape should not be super sticky.  It is a pressure sensitive sticky. It should be pliable and slightly sticky much like putty. Imagine putty rolled into a ball and left out for a while.  The design is to stay in place until it is functional. Like gasket material. If you have any concerns, please ask Amazon for an exchange.  We want you to be completely satisfied with your product.
