Alberg 35 Hull Painting Coverage
I'm on the home stretch of a complete strip of my hull down to the gelcoat, and I thought I'd post a few pieces of information about paint coverage and surface area that I couldn't find anywhere before I started so that hopefully, the next time someone is googling around for info they might come across this. You guys have been really helpful at a few stages of this project, so if I can be helpful to someone else, that'd be great.
I've laid up the paint in relatively thin coats, going with a 1/4" nap for the interprotect 2000e and 6" foam rollers for the VC Offshore bottom paint. Although I initially attempted to roll and tip the first couple coats of interprotect I had no success whatsoever tipping it - it just clumped and streaked no matter which brush I used, so I pretty quickly ditched the brushes and just rolled out my lines as best I could. It's not perfect, but it really does look pretty good to me.
I used most of a gallon of interprotect per coat below the waterline, not including the 6 jackstand pads which will be moved after I finish the bottom paint. The Interluxe web site claims 216 sf per gallon when rolling, so 215sf is probably a good baseline number for the SA below the waterline - maybe add about 25 sf for the jackstand pads and another 15 sf for the rudder, which I haven't painted yet.
After the final coat, I waited 24 hours and knocked down high spots and gave it a quick scuff with 80 grit before applying bottom paint.
With the VC offshore, I used just over 1.5 Gallons for 2 coats, and the web site claims 270 sf/gallon, so this backs up the rough 215 sf estimate for the bottom on the Alberg 35. Again, I didn't bother tipping, as this stuff dries up so fast, but I rolled out my lines and it looks pretty smooth to me. They say you can wet sand this stuff with 400 grit after it has completely dried to get a really smooth finish, but at $290 a gallon, I think I'll just leave it all on the hull, thank you.
Like I said, there are probably only about 150 other Alberg 35 owners out there that this info might be useful for, but I figured I'd put it out there in case anyone is searching. I also found a really nice method for marking bootstrap lines which I'll put in another post once I snap some photos. If anyone has any questions about this project, feel free to reply to this post or send me a message.
