A few questions about paint

ironworker · #1 (**permalink**) 03-13-2011

OK, the weather has finally starting to play nice and I am getting closer to painting my Newport 30. My first question is

1) Some of the hull paint above the water line is probably good enough to polish and be done, other parts are going to have to be sanded, primed and finished, and there are a couple previous repairs that I am going to fair and smooth out. Am I going to be better off getting it all prepped and prime the entire hull and finish or do I just need to spot prime where I make repairs.

She came to me with Interlux Brightside paint and primer so that is what I will be using.

2) There are some spider cracks in the finish in a couple places, do I need to handle them the same as if it were on the deck or just sand them down?

3) When it comes to spraying Brightsides, what method is best? One of the percs of being good friends / neighbors with a commercial painter I have access to a host of airless sprayers and tips to use as well as a good gun man that will work for beer!!!! If airless is not the way to go then what type of air gun do I need?

Thanks

Spider cracks

Here is one of the repairs I have to make that I assume are from rubbing against a pier or something else that was a little bigger or meaner than the hulls finish

This is a pic of what appears to be blisters of some sort. It looks like the finish did not bond very well.I do not want a repeat of this. Any ideas what could have caused this?

I have the prepwork issues figured out (and half complete!!!!!!) I am still looking for the best way to apply the Brightsides

"A grinder and paint makes a welder what he ain't"

LOL!

With the blistering and cracking, I would remain suspicious of the remaining paint adhesion. Even those areas that haven't let go..... yet. Your new paint job may adhere well to the existing layer, but it will depend on what you have now to stay on the boat.

If you have labor that works for beer, why not consider grinding it all off, fair her down and repaint to whole hull? Lots of work, but she would be a beauty when you're done.

Tom, you are the first person to ever comment on my signature. I guess if you don't REALLY know how to weld it may not make much sense. Thanks for noticing.

Minnewaska, I have started sanding above the waterline with 150 an a DA and where the paint is not blistered it is fairly tough to sand down to the gelcoat. I did consider taking it all the way down but I need the get her feet wet in the next month and a half or so because the owner of the trailer she is on wants to pull his boat. She has been on there for a couple years now. Not my fault, I have only owned her for a few months and almost all of that has been bad weather. I do want to get her in the water and out of my driveway as soon as possible though. Unfortunately the beer labor is ONLY good at painting, my stepfather (RIP) said it should be against the law for my neighbor to own a hammer!!!!!

. So that put the burden of prep work on me and a couple friends that have the desire to help but very busy schedules.

I will take her all the way down next time as I will have built my own trailer.

The signature is SOOOO true. Only a fellow welder could or would appreciate it.

I can honestly claim that I have been held off the side of the building by my ankles 150' off the and ground and ran a 3/8 overhead (3 passes) that passed inspection with no touch ups.

That was 10 years ago and before back surgery. I sure do miss those days.

Youth is wasted on the young. Don't think I would feel easy bein hung by my boots that high off the ground. Apprentices sometimes have strange ideas of what is funny and what is not. But then again it IS fun to mess with 'em.

It was my apprentice that was holding me, he was / is a big 'ol boy. The irony of it all was that I was the job steward and that put me on the safety commitee!!!! The job safety man was on a walkdown with the owner, walked out the door, looked up, and there I was. I got a free trip to the general superintendents office on that one. I did prove that it is hard to outwit an Ironworker that knows the rules as well as or better that the safety man!

May have to add "Ironworkers. We get paid to get high!" to my sig as well
