Hi,
In October 2013, I painted the bottom of my 1993 34'
Catamaran with 3/2 coats (waterline/hull) of Micron 66. Prep included pressure wash, light
sanding, and heavy
sanding in damaged areas. There was no general
paint damage of the previous coats although there must have been more than 10 coats applied - all was ablative coat and in many places the
paint was worn to a red flash paint I applied in 2009. It was a normal paint job.
By Jun 1994, much of the waterline paint had flaked off back to the original gel coat. The newly applied paint was stuck fast to the underlying paint on the rest of the
hull, but where I had applied 3 waterline coats, it was flaking off.
I contacted International
Marine. Their local represented visited the
boat at the yard I had contracted to do the paint job, advised on
removal of the Micron 66 and GAVE ME 3 GALLONS of replacement paint. I don't know what paint they supplied, only that the yard charged me $100/gallon to receive the paint from International.
The representative from International
Marine supervised the
work to prepare the surface for the paint gift - a
project that took nearly $1,000 of additional prep.
The paint job looked unacceptable, there was still significant signs of areas where the paint had flaked off, although it appears they did feather the edges. I had approved priming $$$ for the paint flaked to the waterline, but apparently the representation from International didn't feel it was necessary.
Now, just under a month later, the newly applied paint is covered entirely with marine slime except in the areas where the rudders attached. Those areas are covered with
barnacles and marine growth. Clearly the new paint from International has failed to keep ahead of
Lake Worth, even though the
boat is anchored in an area with 2 to 3
knot current and clear
water for much of the tide.
I see no choice but to pull the boat, finish the preparation as it should have been done, and apply another coat.
The questions: What paint should I apply that will last at least a year in
Lake Worth,
Florida?
Thank you.
