After trying Rubber Cement and kids Sticky Glue (with terrible results) I found that Loctite Plastic Bonder works pretty good.

As you may know, almost nothing sticks to polyethylene. This stuff is like super glue with an activator. Here's how I used it.

I cut a new vapor barrier (clear polyethylene, thick as I could find at the home center) using the old one as a pattern . Sharpie marker works good. I chose to only glue it at the top, and then let it hang down and be held in by the screws and fasteners (feedback welcome here).

The activator is like a felt tip pen with clear fluid...you can't see it. So hold up the plastic to the door and draw a line with the sharpie where you are going to glue it. Draw right on top of the sheet. Then flip the sheet over onto the floor and you can see your mark thru the clear plastic.

Draw with the activator pen on top of your line. Wait 60 seconds. Put a thin line of glue on your mark and hold it to the door for another 60 seconds. You're done.


There are other threads on this topic, so read them to get the whole picture. Spray contact adhesive seems to work for some folks...I just didn't want the spray getting all over.

Would be nice to know what the Germans used at the factory.
