Interprotect 2000E

[Hamsandwich]

I am going to get a gallon of white interprotect 2002e epoxy to redo the bottom of my boat, I'm sure I am going to have a lot left over, is there any reason I could not use whats left as a bilge paint? I would probably get white, and not the gray then. I realize it probably overkill but I just want to know if I shouldn't for some reason.

Mix a half of it at a time, and put more coats of it on the bottom. Interlux says to shoot for a 10 mil thickness, which turns out to be 4 or 5 coats of the stuff. You're only going to get about 2 mils out of one coat.

Outside of that, you can use it in the bilges no problem. It's essentially just epoxy primer.

The biggest reasons for gray and white is recoating, as it's easier to recoat another color alternating.

Another thing. It's just me I suppose, but I paint most all my bilges white unless I'm just touching up a customers boat that already has gray. I'm actually kinda curious why gray seems to be the customary color. And for some reason, Interlux's bilge coat, and barrier coat are two different grays.

And on a salt boat, the finish color should be insignificant. If you wear away the bottom paint enough to see barrier coat, it's way too late.

i ended up with 5 coats of 2000 on mine....took almost 3 gallons....then 2 coats of vc 17 made for a pretty good job....

Bilgekote paint may require a epoxy primer such as the Interprotect

3 gallons on the bottom of a cat 22? Where? This isn't much bottom-sides on a cat 22. I dunno I never used it before, does it just not go very far? I plan to put hard anti-foul on top of it and maybe vc-17 after that more for speed than anything. I usually gain almost half a knot with vc-17.

Ham, a half gallon will cover a 22 easily. I've usually come close in square footage on a boat by simply calculating the length times the beam, which is around 160 sq. ft. on the 22'.
If I were doing it, I would put 2000 on it twice, just mixing a half of it at a time. Ya need to wait about four hours between coats. Bottom paint it the next morning to take advantage of the chemical bond. Splash in the afternoon. Sail that night. Drink Margaritas on the money you saved by not putting so many barrier coats on.

I have to tell myself everyday that I'm not restoring the U.S.S. Constitution..

Well said Chris, although I do appreciate the OP for letting me know about the recommended 10 mins thickness. I will see how it goes, if I need another gallon I can always grab another.

I'm in fresh water only too here in WI. I am about as far from the brine as I could be.

I look forward to getting her done and enjoying those margaritas at sunset..... makes it all worth it.

to clarify.....i had to sand all the gelcoat off due to about 10,000 small osmotic blisters.....so i put more on than one would if they had just rough sanded the bottom...

i ended up with 5 coats simply because i only wanted to do it once.....lol


i agree that a gallon should cover two coats to a thickness of about 4 to 5 mils...

Luckily I don't have any blistering on her bottom, just that typical old gelcoat hairline crackyness. I'll slob on 2 coats and see how she looks, more than likely I will get another gallon and do 4 coats min. That should get me close to that 10mils.

Thanks guys all the info really helps. This is my first time redoing a boat. I'm learning fast. LOL

We'll I've done some homework and I have decided NOT to use the Interprotect 2000. I have decided to go with the Awlgrip 545 Epoxy primer/converter(and I will probably use the accelorator as it will dry faster and keep bugs from landing on the finsih). The interprotect is $80-90 a gallon and the Awlgrip is only a little over a hundred a gallon. Price is almost the same. This way I can prime the bottomsides and all the way up the topsides to the rubrail all in one shot. Then White Awlgrip to the topsides above the water line. If you really add it all up the price difference between Interlux Perfection and Awlgrip is almost nil. I plan on rolling and tipping.
