Gelcoat advice needed

Post by charleston14 » Sun Aug 11, 2019 7:06 pm

Hi folks, today I became the proud owner of a kayak with a number of “badges of honour” on it.

I say proud because the Anas Acuta is a classic, but at the moment the boat would benefit from a makeover.

At some point in its long past it had an owner who’s answer to scrapes , scratches and chips, was to paint over the gelcoat cracks and such, with resin (translucent green) rather than do a gelcoat (flowcoat) repair.

Funtional, but not pretty. Like it’s current owner.

It’s a valley boat so the gelcoat is thick; it could be sanded buffed and polished up like has been done on a Nordkapp makeover on this forum

I want to remove these old repairs: what’s the best way to remove the old resin that’s been brushed on top of the gelcoat? Can I sand it off without adverse damage to the gelcoat around it, scrape it off with a Stanley knife blade ? Would it soften and come off easier with careful use of a heat gun?

Can’t imagine there is a solvent that would de-bond it without also messing up the gelcoat.

Unless the hull underneath has been sandpapered before it was painted on (which seem unlikely) it will not be well bonded and will probably flake off with a scraper or a gentle push with a sharp (but wide) wood chisel. I would not use solvents or heat. Sanding is possible but will be hard work and will tend to remove adjacent original gelcoat as well.

I keep a chisel for this kind of work, do make sure the edge is good and it is sharp before you start - nicks on the edge will tend to cause scratches in the surounding gel.

It does indeed flake off in places, with a bit of encouragement.

Ah yes the humble chisel..why on earth did I not think of that!
