Paint removal will be with razor blade and heat gun. Should only take a few hours to get rid of 90% of the paint. Rest will have to be done by hand, with stripper, or media blasting.
Just heat up a small area with the heat gun and it scrapes right off in big strips.
I have some Picklex on order to treat the bare metal for now. Need to source some epoxy primer locally.
Got the tar scraped off the floorboards. Several hours worth of work with the heat gun and a scraper. Using dry ice to freeze it would have been easier, but by the time I figured out how to say "dry ice" in Italian and figure out where to buy it locally, I would have been done.
About halfway done in this picture. I need to get after the caulking/seam sealer with a wire brush on an angle grinder. I also need to finish getting the tar residue off the floors - I'll use diesel or some sort of solvent to get down to bare metal.
Floors look pretty good under the tar, but I did uncover a few areas that may need some attention. Wouldn't have found these if I hadn't removed the tar.
Just for sh*ts and giggles, I weighed most of the tar that I removed. Came to 20 lbs. Not earth shattering, but a step in the right direction.
Need to get the undercoating scraped off the bottom, too. Plan at this point is to patch the floors instead of replace them entirely but will make final decision after I get it all undercoating off.
