I’m installing 6 mil poly sheeting as a vapor barrier over pine tongue and groove panelling in a timber frame structure. Plans call for lapping the sheets and sealing with acoustic sealant.
I’d never heard of acoustic sealant before. Cannot find it at local hardware/big box.
What kind of product am I looking for? A solvent-based synthetic rubber? How about the DAP “Sidewinder” product?
I suppose what I want is something very flexible that will move with the wood, and that will bond plastic to wood. What am I likely to find at a Lowes or Home Depot?

Owens Corning makes a product called Quiet Zone.
Another one that's carried locally is called Noise Stop.
There are several out there.

"Black death"
good....glad I not the only who has succumbed to the evil punishment of working with Accoustical seal. I'm sure somehwere on the tube in very fine print there must be a guarantee that you will get it on you no matter what.

What Bobtit said. Black death indeed. The insulation subs like to use it to seal the 6 mil to the bottom plate, but I now insist they use tape. It is very similar to roofing goo. You will find it on everything and it is murder to get off.
Permatite makes an acrylic sealant which will stick to polyethylene.
I got it from McMaster Carr when I was trying to find something to seal poly to foam ICFs.
It was about the only thing I could find that would stick to poly.
I even called several adhesive companies and spoke to their specialists trying to find something.
The acrylic sealant worked very well.
Name, give with the name of the stuff, already !;o)
Yeh... That'll work.
I did - "Permatite Acrylic Sealant". Comes in 10 oz tubes.

Thank you.Permatite is a brand, and acrylic sealant sounded like just a description. Usually there is a specific name and/or number involved.
Yeh... That'll work.

Wait a minnit.
You are installing plastic OVER tounge and groove pine panelling ???
>>Wait a minnit.
You are installing plastic OVER tounge and groove pine panelling ???Yes. It's a "wrap and strap" wall package over a timberframe. Frame[ then borate-treated 7/8" EW pine t&g OUTSIDE the frame (visible from interior)[ then 6 mil plastic[ then 3" faced polyiso foamboard inside blocking[ then straping and CVG cedar siding on the walls & 5/8" plywood + felt + metal (terne) on the roof.Plastic is there to prevent moisture drive into the wall from interior. Strapping forms a drainage plane behind the siding.My question was about properly installing the plastic at the edges and seams.
If you go to the auto body repair industry, they use something that looks and sounds like "Black Death" only it comes in 1/2" wide roll$ with a backing tape, just like any double sided tape.They use it to tape the wind/noise plastic barrior to the car doors under the finish panel.Since you can apply it at the rate of beau coup feet per minute, and there is no cleanup, I imagine the labor savings would pay for the extra cost of the roll$.SamT
Ah.Ok, carry on.;o)
Yeh... That'll work.
