We then found some moderate blistering which we ground out with a dremel tool and patched with epoxy. Mechanically stripped the old paint to bare gelcoat. The boat was at the Jamestown Boat Yard in Rhode Island-considered the premier "bottom problem" experts in this area. When we bought our 33 last winter the bottom was in sad shape from neglect. That way when the bottom coat starts to show you'll have a good idea of how long before you need a bottom job and you won't have to deal with a bunch of old dried up modified epoxy coats of paint. The first coat should be a different color that the other 2. These are ablative paints that "sluff off" as you use the boat.
It's a long and somewhat expensive process, but if done right you shouldn't have to worry about the bottom for a long time.ĭepending on what part of the country you're in and how much you use the boat, you might consider putting Petit ACP-50 or Interlux Micron CSC on. I put 4 coats on my 42 after stripping the gel coat off and repairing blisters and sealing the bottom with 2 coats of Interlux 1000/1001. I recommend rolling it on rather than brushing as you get a more even coat. You need at least 10 mils of barrier coat. Timing between applications is critical and a light sanding is helpful between coats. Like any kind of "paint", preperation is extremely important. As for the barrier coat, I prefer the Interlux 2000/2001 system. Any blister not repaired will come through any barrier coat. Next thing is to check for blisters and have the ALL fixed. As long as it's all off then you're okay. As for chemically removing the paint, that's up to the yard.
Eventually the oldest paint is going to flake off. Tom.įrom: Roger Wright your boat has 10 coats of old paint of the modified epoxy type (Petit Trinidad, Interlux Ultra-Kote, etc.), it's time for the paint to come off. Well, it isn't the 1500.00 that worries me.Is the barrier coat applied to the gel coat or to the Glass/resin under the gel coat.Does anyone have any experience with this ?help. He promises the bottom will be baby butt smooth and that it is the right thing to do. THEN he will apply the barrier coat (numerous applications) and when hardened, he will then apply a couple of antifouling coats. My trusted gel coat man tells me that we need to remove all the paint with chemicals and then REALLY clean the remaining surface. My poor old 32 has about 10 coats of old paint on her bottom.
