quick question re: Shrink Wrap seams (heat weld or tape?)
I am going to be shrink wrapping a large boat for the first time today. Support structure is built, everything is ready to go, borrowed torch, etc.
I have Dr shrink in 24' wide roll, but I need to cover a ~40' wide area (well 26' wide but (2) 10' tall sides), meaning one main seam that has to be strong and waterproof.
-should I just overlap a foot or two and heat-weld the two pieces together / OR should I use shrink tape? (I have one roll of 6" wide tape) If I use shrink tape should I overlap (a foot or two, or?) the 2 pieces or tape them edge to edge?
-should I try to attach the two sections together on the ground or once they are in place? - I am worried about being able to get a successful seam because either approach has downsides-
-If I heat weld the 2 pieces together on the ground, I think that the material might shrink significantly towards the (center) seam especially because the sides are not held in place by a bottom band...making the entire piece possibly not "long enough"- also this will be a large piece to try to maneuver into place.
-If the two pieces are spread over the structure separately, the only access will then be from the inside. I am not sure about being able to "pat" the two sections together if I were trying to do a heat weld in this case, and taping the entire seam (whether or not there was an overlap) could be quite a challenge...
-also how well would the tape stick to wood (framework of structure, equivalent of "bottom band")
I know that the correct approach is to fold the bottom of the shrink wrap up over the bottom band and heat weld the two pieces together, but in some places this won't be possible
