I'm just about done prepping my hull for a barrier coat and bottom paint and would like some advice on the application process.

Below the waterline has been DA'ed with 80 grit and wiped down with a prep-solvent. I plan to fill a few areas with Epiglsss and then rough that with 80 grit. My plan is to roll the barrier coat (Interprotect 2000e) on with a roller and to apply 3 coats on the hull.

Some questions:

Is 3 coats enough? I don't really need to alternate colors do I?

Is 45 minutes enough time for the first coat to get tacky enough to lay down the second and third?

Should I roll the bottom paint (micron 66) over the barrier when the barrier is still tacky?

If so and I run out of daylight, is it a bad idea to roll the Micorn 66 the day after the last application of barrier coat?

Been 5 yrs, so going off memory here.....
I used 3 coats and altered grey/white/grey for easy identification between coats. The grey does cover better thou. seemed thicker. Use the thumb print test between coats. When its soft enough to leave a fingerprint in the coating, but not come off on your finger, you are ready for next coat. 1st coat of bottom paint goes on last coat of 2000e within same thumb print test. Otherwise I think you gotta scuff up the barrier coat, roll on another, and then bottom paint within thumb print period. Has to have that good mechanical bond. Roll on an extra coat of bottom paint on the keel, chines and along water line. (High wear areas)

There tech line is super helpful on applications.

For clarification, I used CSC since I'm freshwater vs the 66 for saltwater use. So

Thanks US1. Did you wait a few days b/f moving the boat stands so you could barrier coat and paint under them or was 24 hours enough time to lift the boat and move the blocks and stands. Also, how long did you wait b/f you splashed.

Around the stands and blocks, I staggered back the barrier coating a couple inches from the previous coating, and did the whole bottom. Moved stands, then did those locations overlapping each coat onto the new corresponding coats. I did all my barrier coating and 1st CSC coating 1 day and stand locations the next day and, so it all was within the application window timeframe. After the 2nd day, the whole bottom was barrier coated and 1 coat of CSC. The rest of the bottom coating layers were done later in week.( Gotta get that 1st coat onto the last barrier coat, then the window is months I believe that the rest of the bottom paint coats can be rolled on, as long as boat is never splashed. Otherwise you have to scuff sand) This was all confirmed by Interluxes tech line. I splashed the next week, so time frame was not an issue. I just rolled on all that I could, then when set the boat on the trailer, I hit those 4stands and 2 keel blocking locations. In water a couple days later. Some A/F paints have a very short time from application to splash (hrs??), and some months. Product dictates timeframe.

Thanks.
