CarpeDiem 575 Posted June 21 Share Posted June 21 I tried. Couldn't buy it. Professional use only they said. Aka - I was not part of the aporoved cartel. I found a group in Australia that sold it but looked no further so no idea how hard it is to ship/import. Quote Link to post Share on other sites

DeFoul Antifoul Removal — HullWell Advanced Marine Coating Technology New Zealand (NZ) A long time ago we tried something like that. It was like a goo, you paint it onto the AF and leave it for a while. I can't remember the brand name. You needed to stop it drying out, as in try and cover it with cling film or something. It softened the AF but didn't actually remove it. Overall didn't save much labour and the benefits didn't offset the cost of the product. Think we did a test patch (about 1m square I think) and determined it was just easier and quicker to get stuck in with the old fashioned scrapper. BUT, this was so long ago all of the details are extremely fuzzy. So don't take what I say as gospel. Would have been at least 15 years ago, as we are on our 2nd round of copper coat.

Frank 232 Posted June 22 Share Posted June 22 Coopers Strip Club apparently if you believe the blurb, I think you still have to do all that cling film faff etc, otherwise just buy a packet of linbide scraper blades and take the sharp corner off then have at it. You can easily adapt the handle to a vacuum with ingenuity and gaffer tape. https://coopersstripclub.com/marine-lpp1/#:~:text=Coopers has been used for,Paint%2C Enamel Paint%2C Acrylic Paint%2C Quote Link to post Share on other sites
Island Time 1,351 Posted June 22 Share Posted June 22 Use a scraper, as frank says. About 1/2 the width of the blade at a time, work along. Surprising how efficient it is. I scraped 100 KG of antifouling off IT! Must have been about 20 layers... I know because I vacuumed it up and the bags were about 100 KG.... 1 Quote Link to post Share on other sites
Psyche 958 Posted June 23 Share Posted June 23 Defoul is basically bio diesel with some alcohol and emulsifier Not withstanding that it may be a great product, you don't get something for nothing. There is always a lot more work involved than what is shown on the videos, even using the most evil strippers it's a very messy business. I see it retails for 660 in Oz, 19 L which is enough for a 30 foot boat, add on the New Zealand tax and markups.... The easiest way by far is to get somebody to soda blast it, the next easiest is to get a team of students or your crew with scrapers. Scraping is the best way to get it off as opposed to sanding or any other DIY method. If it was me, I'd get a Tyvek suit and a full face respirator, a linbide scraper and a 10 pack of blades. It's going to take a few days! 1 Quote Link to post Share on other sites
Frank 232 Posted June 23 Share Posted June 23 If you can get one of these long handled versions or otherwise stick a chopped off broom handle up the shank of a short one . There is supposed to be a knob on the top near the blade but someone has removed it grrrr. Quote Link to post Share on other sites

aardvarkash10 1,179 Posted June 25 Share Posted June 25 can thoroughly recommend soda blasting. Once you count your time and hardstand time, the cost of beer and sunstroke, it's a bargain. You still have to tidy up little areas, but the surface is great - paint sticks to it like the proverbial defecation to the night-time thermal insulation layer. 1 1 Quote Link to post Share on other sites
whitepointer 36 Posted June 27 Share Posted June 27 I scraped back Lidgard 35 Whitepointer 3 years ago using hand tungsten scraper from the tool shed, two handed scraper, worked well but seriously hard yakka for about 5 days, then had to follow up with filling the scrap marks and orbital sanding 2 Quote Link to post Share on other sites
