bottom paint--Trinidad over Ecoclad???

[sailingcamelot]

I had Eco clad bottom paint professionall applied to my 9m Catalac 18 months ago and am less than pleased with the results here in Tampa Bay. I want to return to the tried and true Trinidad bottom paint. Since Ecoclad is a 2 part epoxy hard paint and it still has good adhesion to the hull can I just haul out, scuff it with 100 grit and apply trinidad over the ecoclad? The last bottom job was a real pain and expensive. Removed all the old paint with a stripper, 2 coats of Petit barrier coat and then the Ecoclad. This time I plan on doing the job myself and really do not want to repeat the last experience.

At a certain size bottom it makes more sense ion my opinion to use a hard paint like Trinidad, but every few seasons only. Haul and scrub annually, renew the sink and clean the prop without the expense of being blocked. Use the savings to a diver to scrub it once every 10 days.

For a 35 foot boat you save each year you don't paint:

no blocking - about $350
No sanding, masking - about $250
No bottom paint - about $350
No paint application - about $350

That's about $1,400 saved.... and if the diver is $75/dive that's 18 x 10 days - 180 days which is 6 months and you gave someone work (diving) and didn't foul the environment or add weight to your boat.

I see your point. I have a diver scrub the waterline and props monthly and he now says it is time for bottom paint.

E-mail or call Petit. They are good at telling you what is OK over what and what will require a sand or a tie coat.

I don't change my sinks on a regular basis. Is there something I should know? Apart from some slight staining to the stainless steel, they seem to be holding up fine.

The Eco-Clad web site no longer exists. I don't consider this to be a good sign.

Is your advice to use no anti fouling paint whatsoever?

No it's not.... only every 2 or 3 yrs.

Thanks to all for your comments. Especially Paul L. I emailed Pettit and was advised to sand with 80 grit and apply trinidad over the ecoclad.

Not too painful
