Antifouling paint stripper

[clucas]

 I got the best price on Dumond Peel Away from my local Sherwin Williams.  Same stuff minus shipping charges for 5 gal buckets.  Great stuff and much more effective than CitriStrip.

Yeah, wear a full-on bunny suit, gloves and goggles. Oh, and shoes you don't mind destroying. Nasty shit but it will do the job.

We've tried several stripper methods & products in our yard over the years. But the effort, mess, PPE and pretty substandard job in the end made us go back to Soda Blasting. Cheaper in the long run, safer, easier and better job for sure. YMMV

That's what our local yard says. They don't strip bottoms any more. They refer you to a soda blasting contractor who comes in.

You're a club.  There's multiple boats.  Offer a deal for some free advertising eg "sponsored by Bob's blasting"or a tax credit(if possible).  Not sure if it's the same as for a charity.  Call a few blasters, find out their slowest time of the year, have all the boats ready to go.  Blast and be done.  The liability in volunteers and drippy goopy stick shit that can cause injury doesn't seem like fun.   Stands and tapping could all be set up for 2x boats at a time, blaster alternates back and forth, volunteers do the setup and teardown/cleanup.

I have tried everything mentioned, Soda Blasting is the way to go. BTW if there is a barrier coat the blast wont effect it.

I found what might be an interior varnish stripper

After antifoul removal it’s recommended to apply an epoxy substrate primer before antifouling 

antifoul adhesion is greatly improved 

Pictured is the classic antifoul adhesion problem 

the black colour is epoxy barrier coat

Picture above is a classic case of missing over coating window. If you get the timing right after epoxy application the antifoul with etch itself into the epoxy. If you miss the window and the epoxy is cured, the antifoul just sits on the epoxy as appears in the picture.

Rule of thumb, if you've applied your epoxy, in 3-4 hours you press your thumb onto the epoxy, if it (the epoxy) comes off on your finger, it's too early... If it just leaves a fingerprint, you're good to apply the antifoul.

Yes indeed , 

boats are typically antifouled outside , in the spring 

many chances for a “ mistake “

a classic contamination is morning  dew running  down the topsides and contaminating the bottom
