Refit finances - advice wanted

[Fore and Aft]

Mithril Bham I was thinking the same thing about the interior and wondered if a good whip blast would remove the bubbled paint and then a proper Nace 3 blast on the rusted areas. Followed by some new paint to seal it all up.

I might be headed that route. I have a lot of time and don’t mind wasting it if I can make it work.

Thanks for your input!

RownaB your biggest issue is going to be removing the sand inside the yacht after the blasting. Then being able to get a sufficient paint thickness on all those hard to reach areas. The blasting and painting are both jobs that need a fair bit of skill to be accomplished properly.
No reason you could not achieve this yourself but be prepared for a fair bit of effort.
Size really has little to do with it, the sand blaster is correctly estimating the amount of effort to remove the old coating in hard to reach places. I know I could sand blast the inside of a steel 35 foot tank fairly quickly. But put frames, stringers and an awkward shape into the mix and the time factor really goes up.

If I do go the route of doing the work myself, I will definitely use the wetblasting method that really limits dust. Of course, PPE is still needed, but it’s not as bad as dry blasting (by all accounts).

As for the interior, it’s already gone! I took it out when I bought the boat so it’s already just an empty tin can with a rudder on the back. Also, most of the metal is quite accessible so I shouldn’t struggle too much. As for the current paint, I believe it is at that stage where it hasn’t totally failed but it’s bubbling in places and should really be replaced. So if I have to leave it in certain places it wouldn’t be the end of the word.

in a sense, this might be what I do. The paint isn’t bad anywhere. In fact it is only visibly rusty in the few areas where wood was glued to the metal. I guess it held moisture in.

In any case, leaving the paint in certain hard-to-reach areas would not lead to catastrophe.
