Removing paint from inside grp hull

[Poignard]

I need to remove old paint from quite a large area of the inside of my boat's hull. I could use a high-speed angle grinder but the boat is 'in commission' so I don't want to produce huge clouds of dust, if I can avoid it.

I wondered if using one of these things in an ordinary electric drill would be any good :

Anyone tried them?

Humm, using chemicals might be better, probably less intrusive than any grinding off of surfaces.

Anyways, is the removal really necessary? Is it for cosmetic or maintaiance reasons?

When I have tried things like that in the past they have either been ineffective, or clogged very easily, or both. I am not sure you will do much better than wet and dry sanding paper/discs (used wet of course) either manually or on a rotary drill.

Just finished doing this on the project boat. Tried everything from orbital sanders to flap discs/wheels. The best was the surface preparation wheel from Screwfix. But it's dusty. No seriously dusty. No way to use any abrasive method of removing paint with lots of dust.

A wire cup brush and an end brush for the corners might be more convenient in an electric drill. Also from Toolstation.

Try these. Good at removing paint without damaging the substrate. They will make a lot of dust though.

I can't see that it matters what shape the motor comes in - any form of spinning abrasive is going to generate lots of dust.

Drywall sanding mesh, used wet, takes off antifoul quite effectively without producing dust or clogging. Maybe it would work on paint inside the hull too?

If you are removing paint it can only go in one of 3 places - into the air as dust, onto the stripper to clog it or into water. So the only way to avoid dust is to "sand" it wet.

OK thanks for the advice and opinions.
