A: Hi, please know that the LTB-400, while versatile, is not UL listed. I would recommend using HTP-1010. This product is UL listed, is insulating, and unlike heat shrink- it does not require a flame or heat source to install. It bonds with itself to provide a water tight and insulating seal.
A: Not on my house. The fire risk is unmeasureable,if small.
A: Hello and thank you for your question. Yes, you will be able to seal this application to waterproof it. You will need at least 2 coats of the tape, but may need to apply more. Please read the instructions carefully.
