Laminted frames sticking to hull

[Lit Hudgins]

I am laminting some new frames in place and was wondering what I could but in place to keepthe epoxy that squeses out from sticking to the hull

Wax paper maybe?

Thanls for any help

Gidday and welcome Lit :cool:

I understand that plastic is the best coverall to keep epoxy from sticking to other nearby surfaces... although in frame work say plank on moulds work I believe the recommended is for duck tape to be laid over the mould first... but then on reflection the way I read your post is that you are replacing frames?... this is likely to be different so I will defer to others.

Hopefully some more able commentary will come shortly.

Packing tape, as opposed to duct tape, will do the job. If you are glueing up the frames and then removing to finish them, then a couple of strips wider than the frame width should do. If the packing tape fails to adhere to the hull, by all means, lay down some duct tape and then the packing tape. I have used packing tape exclusivly when moulding up small parts outa fib*****ss and never had any problems.

Packing Tape works great! Nothing sticks to it
and it's cheap.

Be careful handling after you've pulled things apart. There will be some knife-sharp edges on the dried epoxy from where it ran out against the tape.

Celophane packing tape sure does work well as a no-stick surface on a mold object. Where can it get it wider than 2"?

Sounds as though you're laminating into an existing hull. If that's the case, I've used wax paper, thinking the width and dispenser were handy, but found it easy to tear. Best solution was bits of 4-6 mil plastic as found in drop cloths, small tarps, etc. After wetting all the laminations with epoxy, we'd just wrap the stack up in 2-3 layers of plastic, then clamp/screw them to the hull. None stuck where they weren't supposed to, yet still lay down perfectly in position. And since none weeped out, things stayed nice and neat/clean!!

I just cut ordinary plastic garbage/yard bags to size. Sometimes I cover the entire workbench that runs the length of the garage with them to lay out several pieces of wood for encapsulation

I've used waxed paper, but I was concerned that some of the wax might transfer to the stock and affect later bonding or finishing.

4 mil polyethylene is very inexpensive, about $.02/ft^2) . I keep a roll (10' x 100') on my f********* rack.
