Applying graphite

Post by jbo_c »

Is a roller still the preferred method for spreading the epoxy/graphite mix onto the boat? I’ve almost completely gotten away from rollers and brushes with epoxy because they seem to soak up so much.

Seems like the preference used to be a short nap paint roller rather than foam. Still the case?

Thanks.

Been a while since I've done it. Mostly I think I ended up with short napped paint roller. Truth is nothing worked all that well for me as I was so often troubled with of little "nibs". The more the resin and graphite are mixed the better. In the end it works out--just get several coats on and get her flipped over. And don't look under there again :wink:

Apply the crap on and warm it with a hair drier. Same results with putty knife, brush or roller. Crap until you warm it and it flows smoothly. Use slow hardener though. Heat kicks it fast.

Haha. This is mostly the plan. This is a pokey boat anyway. Good enough will definitely be good enough. Anybody that complains about how the bottom looks will just need to find a new way to get on the water.

Thanks, guys

- and I made screenshots of that link so I wouldn’t lose it, Jeff.

Only trick is that it’s pretty cool here for the next 10 days and I really want to get it done and flipped.

How much graphite is “enough”? Does full color indicate full coverage?

I had anticipated doing three coats, but two has given me what looks like really good coverage on all but corners. Is two coats enough? I’m going to do the corners again, but do I need a third coat on the rest?

Thanks.

If I was happy with the looks as it is now I would do the corners and call it good.

It depends on how much graphite you add to each load of epoxy as the graphite is the scratch preventer. If only adding 20% then I would do 3 coats if 25-30% then you might get by with 2 coats.

This right here, you want enough to prevent most scratches. I did 4 but my boat is only 15' by 4' and I didn't do the front 2.5' of the bow since it doesn't hit anything but the trailer. Also, if you're at all UNhappy about the bottom, now is the time to do the extra layer.
