remove anti-fouling

[Woody]

I would like to remove all the old anti-fouling, and get down to the gel-coat, tried the tinned stuff, got no where, thinking of getting the sand-blaster on the job but would be glad of a little advice first

There is a system in which you spred the gunge on then cover it with a plastic sheet for a few hours. Watched someone using it and it worked realy well, less mess to. Sorry I don't know what it was called. Anyone else herd of it?

There is a slurry blasting technique, fairly new on the market, was seen on tomorows world, it is excellent, I have seen the results and considering the other methods, clean and cheap, onløy one problem, I cant remember the name, its advertised frquently in PBO.

I tried the Caustic Soda -based treatment that can be purchased from most chandlers. Not a nice chemical. It worked fairly well at softening the antifouling. I had 17 years of paint to remove, so it involved a lot of very hard work. If you can afford it, go for slurry blasting.

The 'buy it in a tin' treatment must be washed of carefully as it can soften gel-coat if not removed carefully. It also in my experience does not remove the 'hard stuff' ..... easy stuff OK.

Slurry blasting is the best way ..... it takes it down and also 'wets' the residue such that it doesn't get inhaled like the dust .....

For small areas, you could always use the Pressure Washer Blaster attachment with care ....... but professional blasting is advised ......

Just done my Shrimper (only 20ft though!). Took a day and a half. Used a hook scraper with a tungston carbide blade. Very effective but a foul job and very knackering! Scraper was a Sandvic - £16 from any good tool place. Cruisermart do a cheaper one as well as one that takes a vacuum cleaner hose at £25.
Wear a mask for this method as the stuff is toxic.
