Just make sure the Pettit Protect will adequately adhere to the existing
paint.

I am planning on barrier coating the bottom in the spring with Pettit
Protect after soda/walnut blasting this fall. One question I came up
against was the soda blaster asking if I wanted the previous barrier
coat removed. I have no idea what is on there given that it was done
by a PO. But I can't see any obvious reason to remove the prior stuff
if it is in good shape and the Pettit person I talked to agreed.
Thoughts from the group? Dave

Dear Dave J,
I would agree w the yard and apply 7 coats. It's more than what
Interlux recommends but the cost of paint is minimal compared to the
cost of sodablasting and fairing the surface. I also think
alternating the colors is the easiest way to prove how many coats
went on the hull especially if you want proof of warranty. It is neat
to see how it changes the look of your boat, too.
If you are rolling it yourself, you'll find the extra coats are easy
to apply since you'll have your setup and mixing technique honed to a
professional execution. The result is very hard and the peace of
mind after executing a job well is priceless.
Temperature is critical to the minimum wait time and the maximum
procrastination time between coats. The can has a tabIe of rules that
allow many different scenarios. I rolled 6 coats white and grey,
Fall of '07. Some days I got two coats on but I couldn't stand the
smell when it cures, so would roll a coat on and leave the boat, come
back the next day or sometimes next week depending on weather. You
have to monitor the temperature of the hull surface (not airtemp) and
the cooler it is, the longer you have to wait between coats. When
it's 50, the minimum wait before overcoating is 5 hrs, so one coat
may be all you can finish in a day. You can wait up to two weeks
between coats, and 50 degree weather and rain and work delayed my
project which completed within the rules, but took me two months of
weekends.

To tack on to Jake's comments. The can will give coverage guidance
so you can use that as a guide for thickness too.

I'm having my boats bottom soda blasted and then I'm going to be
applying a barrier coating. The yard recommended 7 coats of
Interlux Interprotect 2000E barrier coat which frankly seems a
bit much. According to them, Interlux (who recommends 4-5 coats
10 mil minimum) won't honor their warrantee if you use less.
Never short for opinions I'm hoping you folks can provide me some
recommendations for barrier coatings.
