Drying time for red lead primer?

[Thorne]

I feel like an idiot (no comments pleeeze!) but can't find anything in this forum or on the internet about the drying time for red lead primer.

I've put a coating of Kirby's red lead primer cut with turps 50/50 on both the white oak centerboard case and on the fir inside bottom planks of the dory.

The can label has nothing but warnings about lead, none of the usual instructions on use.

The plan was to use maybe another coat of the 50/50 mix and then maybe one of just the primer.

I'll be painting the inside of the centerboard case with some leftover marine enamel that came with the boat, and painting the inside of the dory with either white marine enamel (also came with boat) or housepaint.

And yeah, I *did* read the bits about having to use several coats of either white primer or white paint to cover the red lead to avoid bleed-thru.

(edited to add:) The weather now is the usual California stuff -- sunny days (they say 70 degrees tomorrow) and nights getting to the bitterly low temps of 45 or so...

The red lead I use,can't remember the brand, goes off very fast...a couple of hours .Good stuff.

Nice weather!! I just painted my centerboard trunk with a 50:50 mix followed by a non-diluted coat of Kirby's red lead paint. With our weather of 40 degree highs and lows in the 20's....actually I did it inside with a constant temperature of 60 degrees smile.gif (my wife was none too happy)... the first coat was pretty much dry in several hours, but the second coat took 2 days to by fully dry. I found the second coat to go on like syrup where some of the paint brush marks were still visible when it dried. Has anyone else had this happen? I spoke to one of the Kirby's who said to dilute it a bit to make it flow better. You are correct about no warnings about lead anywhere except to call the US gov if you're interested in finding out!!

Thanks everyone! The 50/50 lead/turps mix dried very nicely overnight, so I figure it will be ready for another thinned coat this afternoon.

What boat are you putting that very nice traditional centerboard case into?

I thought about putting logs/bottom braces on mine, but since it is supported at the top by both thwarts, and on the bottom by a frame and two bottom cleats -- I figured it would hopefully stay in place and not leak at the bottom. I'll also put in vertical braces where the cut frame meets the side of the case (as per Bob's design in the article below). But we shall see... (here it is temporarily propped in place)

I'm gonna bed it in Vulkem 116 and attach from the bottom with some #10 2 1/2" silicon bronze wood screws.

Reviewed Bob S's great online article on making the trad centerboard case for a gunning dory, and it looks like he used glass cloth and epoxy to seal the sides of the centerboard slot and up into the case. How are you planning on sealing the edges of the slot from underneath?

I mixed 20% varnish in with the final coats of red lead primer and called it paint… Kirby’s sort of gave me an OK on this and it has worked out well in practice. It is a very durable finish.

Good eyes Preston! It is indeed a CB trunk for a Haven 12 1/2. I bedded the posts with 3M 5200 and attached the posts and bedlogs with silicon bronze screws. Everything is sealed with CPES. I'm going to paint the inside of the trunk with an antifouling bottom paint as I'll never see the inside of it again once I seal it up smile.gif No fiberglass in the trunk, but the CB will probable be encased in glass. I spent the afternoon beveling the molds and will bend the frames soon.

Great idea -- I may give it a try. But I do have a can of seriously ugly blue marine enamel to use up somehow...

JG - best of luck with your 12 1/2 -- any more pics?

Preston,

I knew your named sounded familiar....it's from the Haven Builders Forum!! If anyone is interested I've got some more pictures under that website under builders:

Haven Builders (http://www.havenbuilders.com/msie4.html)

The pictures aren't up to date, but you get an idea how it's progressing. I'm about ready to bend the frames. The transom was cut out of H. mahogany this weekend after drifting and gluing it up.
