    I have not found anything to keep the seams of MLV together over a long time.

    When gravity wants to pull the seams apart I have noticed creep in the seams. I have used CLD and silver tape on top of that but the seams still want to come apart. I am talking about a 15 degree slope, nothing outlandish. Now with cascade,s vb3 lead product no problem. I would like to get the MLV to stay in place like the VB3 does.

    Tape like this across the seam: XXXXXXXX

    or parallel with it like: --------------

    Parallel then on top across, so I end up with ++++, on each seam. Something on the top layer of the MLV prevents long term bonding with what is in my tool box.

    The hh-66 glue Don sells works very well. Pretty fast, even in less than ideal (cold and humid) conditions.

    HH-66 is really the only adhesive I've found that can be relied upon to bond MLV to MLV. It's not what's on the surface exactly, it's the plasticizers used to make the vinyl flexible, migrating to the surface. Some PSAs that are designed to work with vinyl will also work, but they are a mess to work with when sealing seams.

    How about just using new velcro on the sheet you are attaching below? If each piece is self-adhered to the door, then your seal won't have to support any weight.

    What's the MLV, apart from murine leukemia viruses?

    Edit: it's probably mass loading vinyl, eh?

    Thanks for the clarification, yeah I saw that too.

    It's a pity that SDS became a commercial site now, although in the past I'd thought it would inevidably be at some point.
