removing antifoul

[matt h]

dilunet didnt touch it at all, it was rubbish,im suprised they sell it

On my last hull, i jet washed most of it.2500 psi at around 4-5 inches from the hull In percentage terms prob 30% came off then,
Painted international interstrip, waited 3 mins then scoured it around with scourer pads then painted more interstrip on,Then used a 2 inch metal scraper done carefully to scrape it off,after that i wiped the residue off with a old towel soaked in white spirit (picture 4), then, a new rough scourer again soaked in white spirit,(picture 1 ) and that pretty much it

Hope this helps

matty, how much 1 x litre bottles of interstrip will I need to do my 5,4 do you think? thanks, I've made a small dent in it already using some other stuff you leave on for 24hours - I reckon the stuff was rubbish tho,

[matt h]

couple of litres olly, i think that one shown is a 2.5 L can, Good luck!! get scrubbing

[ollyit]

thanks matt, not looking forward to it!!

If you can cover the Dilunet with cling film for 24 hours that will keep the moisture in.

Might work for the Interstrip stuff too

Shouldn't be too bad to do on the size you have.

I was using the dilunet stuff and it was rubbish, I'm going to buy some international interstrip at the weekend and get a wooden scraper, as I've heard good things about it -

On the areas the dilunet stuff did shift something here are the results, I used a tiny bit of 400 grit wet and dry briefly, then used some Tcut with a cloth -

Whats my easiest way of getting the rest of the hull like this, I know I've got my work cut out here! is there a drill attachment any one can recommend or anything else I havent thought off?

Get it shot blasted.

[matt h]

olly, closely pressure wash the blue stuff with a decent pressure washer not a b and Q thing, roughly 2000 psi, that will really help you

[ollyit]

thanks, I think shot blasting would cost a whole lotta ££ and ruin it in the process -

I'll ty and borrow a high psi pressure washer thanks

right I bought this antifoul stuff called interstrip from international, the supposedly good stuff, what the hell am I doing wrong?!?

I read the instructions, leave on 10minutes and use wooden scraper may need a couple of liberal applications, fine no problem, tried a couple of times, had petrol and plenty of rags to remove residue,

I took hardly anything off, I most dissapointed and left what looks like a really sticky primer and next to impossbile to shift - the crappy dilinet stuff did a better job?! (the oranage sections) admittedly that was left on 12 hours and kind off furred up so to speak

shall I just use a metal scraper? darker area on hull is what it left, I've got a buffing type drill is there a rough attachment I can get for it does anyone know?

I found the international AF useless too, i used Dilunet covered in clingfilm to stop it drying out.
like yours, fetched all the af off but not the primer, that was elbow grease and 1200grit wet or dry.
thats why one side of my boat is grey, the other red....got tennis elbow half way through
in hindsight getting it blasted might of been easier.
i even tried nitromoors on a small area, that softened the polyester gel coat more than the paint

Use a stanley blade scraper then power sand going down in grades, I assume your not looking for a glass finish as the hull will have to be keyed to take the new antifoul.

Hi, When the antifoul has been removed how do you finish the hull, I have quite a few scrapes & bumps in mine so I’ll have to do some gelcoat repairs first. The boat will be on a trailer so there is no need for antifoul although it will need a coat of something? Is flowcoat the right stuff?
