View Full Version : Red Lead in Bilges

Hopefully a quick one this.....painting bilges with red lead (having been well treated with Cuprinol 5*, 3 - 4 months ago) - how many coats do you reckon? (no engine by the way, so oil spills not an issue).

Will you be painting over the red lead? If not then you'll want several more coats than you would if you were using bilge paint.
I've never seen it used over Cuprinol, so have no idea how that might impact the process...got any pieces of wood coated with Cuprinol to test?

Remember that "red lead" is a primer and will chalk off relatively quickly. It's not so good as a stand alone finish.
(I have added 25% varnish to red lead primer for the final coats and had good results...)

This is the orange gloss stuff not the primer, chalking I imagine is not going to be a problem (unless I've got a crap batch!!).
Cuprinol 5* is repaintable (so they assure me...) plus it's had a long time to soak in and dry. It hasn't been a problem with the varnish I applied in the Autumn
Now that's not fair!!! (but I guess I asked for it!)
Seriously though, I haven't used this stuff in anger before and wasn't sure if one is expected to lay down 6 or a dozen coats (c.f. varnish for example) or if 2, 3 or 4 would do - it costs a bloody fortune this stuff (and yes; I know if you need to count the cost you shouldn't have bought a boat!!).
There will be no direct wear on the surface and the boat is only sailed on inland waters.

I did the same thing, Cupronol a Cuprous oxide green bilge paint, let it dry good, then Red lead Kirbys over that: i had no problems. I really did,nt know if that was a good idea, but I had both, RL and this Cuprous bilge paint. So... I will primer over that with Parkers quick dry
alkyd high buid primer # 1640. RodB turned me on to this stuff and it's good. Then I'll finish with a white marine enamel. My boat building mentor just laughs at me with all my concerns with the correct painting technique; He'll then mutter somthing like, well paint is good on a boat. Anyway for what its worth, I believe your OK.:D

theres one boat that only has whale oil on it, nothing else, (the guy's still single )anything to keep the air away from the wood to stop it drying out
