Premium Quality MLV Seam Tape, Installation Tape for Mass-Loaded Vinyl Noise Barriers 6 Mil - Highly Effective Soundproofing Solution - 1.5" x 108 (1)

I am using this to block a very mighty and tiny speaker for my hoot septic system. The alarm is so loud it wakes the neighbors who call security in my HOA who in turn give me fines on something that is required to have. IT WORKS enough to lower it so that my neighbors and security no longer hate me. Thank you.

Didn’t stick in south Florida. I had the mlv already installed. Attempted to use this for the seams. Didn’t stick at all.

It works ok. It comes off very easily unless the surface is very clean. Like electrical tape, it’s only good at sticking to itself, not other surfaces. Maybe a very smooth and clean surface and that’s it.

It didn't stick to my MLV sheets. Maybe the sheets were dusty? But they were brand new right off the roll.

At 1.5" x 108', there's plenty of tape for a whole room, whether you're working on a big area or just a few targeted spots by using smaller MLV squares.The adhesive is strong and creates a solid bond between the sheets, ensuring everything stays airtight. This made a noticeable difference in reducing sound leaks, which really improved my soundproofing setup.Applying the tape was straightforward and hassle-free. It’s easy to handle and sticks firmly without any fuss. Plus, it seems durable and holds up against different environmental conditions, so I expect it to last a long time.Overall, I'm happy with how this tape performed. It's a reliable option for anyone needing to create an airtight seal in their soundproofing projects.

Doesn’t adhere very well

Adhesive not very strong. Hard to hold Mass load vinyl. Not really a good purchase

The tape breaks really easily while pulling off the role, making perfect seam covers really hard to pull off. That being said, it stretches while pulling it off the role as well and gets very thin. It's not very sticky, and generally unpleasant to use.
