- Can anyone talk to me about release agents?
-
- I have made a polyester mould that came off its wooden plug very
- easily however I can't seem to stop epoxy mouldings sticking to
- the polyester mould very badly (I trashed one part of the mould
- at the first attempt!).
-
- I have tried:
-
- 1/. Bees Wax rubbed on and polished off - six "coats"!
-
- 2/. A silicon spray used to lubricate windsurfer dagger boards.
- (Yes I know about painting problems later with silicon).
-
- Both looked OK before lay up (nice shine) but in both cases the
- epoxy stuck to the polyester mould better than it did to the kevlar
- cloth!
-
- When applying wax should it be left to form a kind of solid cost
- or polished off like on car bodywork? I find most of it seems to
- comes off as a white powder when I polish it even gently. Should
- the mould have the shine taken off first before starting with the
- wax? Mine has a high gloss finish.
