PVA release agent

[zoidberg]

I came across a brief reference to 'PVA release agent' without further explanation. Now, I have some threaded bolts*/machine screws to pass through hull, reinforcing and thickened epoxy - and will use these to pull/hold the reinforcing into place while the epoxy cures.

I'll then want to remove those threaded bolts, replacing with a fitting with same-size bolts.

I want to coat the *bolts with a form of release agent prior to insertion. Will PVA glue do the job - or do I need to find something else?

PVA release agent is a different thing. It’s used in moulding and available quite cheaply from GRP shops

PVA release agent is polyvinyl alcohol

PVA glue is polyvinyl acetate

Confusing but different things as lustyd says

I would suggest Op try just axle grease on screw threads before exposing to epoxy. ol'will

Silicone grease will work well too.

Thanks for the replies above.

It seems I have all 3 of the above #5, #6, #7 hiding in my polytunnel.
