Antifoul - Removal

[steco1958]

Can I use, Nitromorse to remove the Antifoul on the hull of my rib ?

Will it damage the gel of the rib ?

Thanks in advance for any comments / suggestions.

Nitromorse do a GRP safe stripper I believe.

I think the normal stuff may damage gelcoat.

Have a look at Reactive resins strip-it
It's not the cheapest but does exactly what it says on the pot!

Tried everything on mine, made no impression so I ended up doing the whole lot with a 1" scraper and sand paper. Horrible job but should be worthwhile in the end. Wish i had known about reactive resins then! Best of luck with yours

I had the same problem and ended up moving very gingerly with a scraper and then finished it off with acetone. That was the only thing that would touch the black primer on my hull. Upside is it looks brilliant without Antifoul!!!

Mine is still in the anti foul removed, now what do I do with it stage! Only been like that for 12 months, I'm letting it air for the time being before I attach it with fine grade wet and dry and a serious buffer.

It is a lot of hull and the thought of tackling the next stage of the process is daunting, perhaps I should do a square foot before I go out each time? Then I might start to make some process.

Thanks everyone for your input, I will be going down the strippit route, hopefully it will be as easy as it sounds (I don't Think).

I did our 46ft Sealine with it.
Realistically it takes off about 3/4 layers per application. On our big boat it took 3 goes to get it back to pretty much smooth gel coat with no scraping involved! Added 3 knts to WOT speed:-)
I've been doing the rib this week and that too will need 3 coats to get it back to a smooth bottom( including the primercon base layer) but in certain places on the hull it's already bare gel coat after 2 applications.
I was careful not to get it on the tubes, not sure if they'd like it too much?

Good luck, it's worth the effort.

Do you intend so to moor your RIB on the swinging mooring without any antifoul and hope for the best.. Will you not have growth on it in no time

The only time I leave the Rib in the water, would be when on holiday in Spain, that is only for 3 weeks, yes there will be a little growth, but that can easily be removed.

As I have the Rib on a trailer, I do not see the necessity for antifoul.

Hi Guys,
Am new to Ribbing (have been cruising and fishing from an ARVOR for years).
My question is; Do I have to antifoul my RIB, it will be left on a swinging mooring from now till November. If I dont, am I mad.
If I have to, is there such a thing as 'clear antifouling' ?

Thanks guys.

I tried several tins of stripit, its bloody hard work. I also tried another one which is a gel and you jet wash off. All in all spent over £100 and about 20 hours and managed to remove less than 1/10th. If you boat has curvy hull shapes your screwed with a scraper!!!

My boat was never keyed, so when the antifoul comes off its a gorgeous virgin bottom. However, by the time you bought several tins of that stuff, there are other options. It all depends what you want it of for, if you want a smooth priming surface for a new coat, i'd just sand it, if you want, never been painted look, go for one of the ARC, soda, or something similar blasting companies. How much do you get paid at work per hour, dont forget to factor that into calculations, and never under estimate antifoul removal

I'd be very cautious about sanding anything that's been previously anti fouled. You'll be releasing harmful chemicals/dust which shouldn't be breathed in.

Did you treat the bare gel coat with anything after the antifoul removal?

This is always what crosses my mind too,could have serious consequences even years later

Have left mine on swing mooring for max 5 weeks and removed all deposits easily with light scrubbing. No special treatments needed. Suspect I could go a little longer without too much cleaning work needed.

This lot seem to do a stripper for everything!
