Yeah, sounds weird, but it's legit. About once a year, usually around winter, I'll up and decide to do some repair and/or light remodeling around the house. Since yee olde homestead is about 85 years old, there's always plenty to do. This year, I decided to do something with the ugly ass, cracked and bumpy linoleum floor in my center room hallway. It's a part of the house I've never done anything with, and I figured it was time to bring it up to spec. One of the things that surprised me is that when I peeled back a bit of the ugly, faux wood checkerboard linoleum, there was actual, honest to god hardwood floor underneath it. It needs to be sanded, stained, and polished, but it's actual hardwood floor. Why would anyone cover up real, rich red hardwood with a cheap fake replacement is beyond me. People apparently didn't have any taste in the 50's. Now my question involves the crap they used to seal the linoleum to the floor, which I'm pretty sure is a kind of tar. It's black, gummy, and takes forever to chisel out. Now if it were any type of relatively modern adhesive, I could soak it down with some remover, and scrape it up in a second. This stuff? It makes it a little softer, but it's still firmly attached to the wood underneath. I have to very patiently work it out to remove it, and it takes forever. It took me about 4 hours to get 1/6ths of the way through it. So is there an easy way to remove old tar like that without warping or damaging the floor itself, or am I stuck to doing things the hard way. For reference, this is what it looks like. That little bit I've done? That's what took 4 hours.
