Hi Eric,
  In answer to your question, our guy used dry sand, in
2010, but even then it was disapproved of for environmental
reasons. He preferred  to work with dry sand but I think
now everyone uses wet sand, as mentioned by Olivier.

Hello Eric,



 



there are now machines that do a
very good job. In France we call it
"hydro-gommage" which can be translated by
water-erasing. In fact, this is a soft sand blasting with
water and a special kind
of sand based on sodium bicarbonate (ARMEX). With these
machines, as Ian wrote, the operator can do a very accurate
job, not removing any gel-coat.



Have a look at GRITCO dot FR (in
english) or aerogommage dash probanet dot fr (french
speaking).



 



Good luck for this job. Your hull
will be happy and faster...



 



Olivier.

Do you think I

Hello Warren,





 





the barrier that AMEL spreads
while manufacturing the hull is made of isophtalic polyester
resin with 1-2 mm glass scales. It is put just after the
gel-coat is spread into the mould.  AMEL started
this process in 1987 as some boats made in Europe were
starting to get "blisters" on the outside of the
hull, under the gel-coat.





 





However, your Sharki may have
never suffered "blistering". Don't use too
powerful high pressure machine to wash your hull (maximum 80
bars) as this is a major cause for starting blistering and
osmosis.





 





Good luck for your hull
works.





 





Olivier.

Great and timely information for
us. We are about to take our Sharki out for anti fouling.






Bill do you know if Sharki’s
built in 1980 also featured this propriety osmotic
coat?





We are hauling out in Malaysia
and plan to use Jotun Seaforce 90.





Any comments would be
appreciated.





Thanks

Eric,




 





I had BeBe hand scraped, then
sanded in 2011. The original bottom paint was an
International hard paint. There was no barrier coat because
it is not needed on your Super Maramu as Amel has a
propriety
osmotic coat beneath the gelcoat... 





 





I have always used International
Micron 66 or Micron 77. I do not believe Micron 77 is
available in the US or any country influenced by what the
EPA allows...I have seen it here in Martinique.
FYI, the EPA has not approved a single new bottom paint in
the last 7 years (politics). Micron 77 is better than 66
because you can take 77 into fresh water...77 becomes inert
after too much fresh water.

Hi Eric,







 







We had the bottom of Pen Azen dry
sand blasted with a machine operator who was millimetre
accurate. When he finished  the gelcoat looked as if it had
just come out of the mould. You wouldn't think
it had ever been painted.







  We put two layers of clear
epoxy on and then we Coppercoated.

Hi,





I was thinking
of having the bottom of Kimberlite stripped and
painted.





I have been
using ablative paint for the last 13 years and the bottom is
no longer fair, regardless of a number of heavy sandings.
Has anyone had their boats bott om and keel
media blasted?  Someone mentioned that media blasting will
harm the gelcoat.





Also, would
you recommend a barrier coat if I have the bottom paint
removed to the gelcoat?





Was the
original factory paint hard epoxy or ablative paint? What
was applied to the keel?





Olivier, what
would you recommend?
