Why does nobody talk about the glue lines on that old school vinyl sheet flooring?

I was helping a buddy demo a kitchen in a 1970s house and we found the original sheet vinyl still down, with these perfect 1/4 inch glue lines you could see through the backing. It was holding like concrete after 50 years. What's the modern adhesive trick to get that kind of long term bond without the mess?

Yeah, that old cutback adhesive was basically asbestos fibers in tar. It's banned now for a reason. Modern water based adhesives are safer but just don't have the same grab over decades. The trick now is perfect floor prep and using a pressure sensitive adhesive meant for sheet vinyl, but it's still a different beast.

That old cutback adhesive was basically a permanent chemical weld, not just glue. @logan_mitchell is right that we can't get that stuff anymore, and honestly, we shouldn't want to. The health risks were huge. Modern adhesives rely on a perfect bond to a perfectly clean, smooth, and dry subfloor to even come close. Miss one step in the prep and the bond fails way sooner. Isn't it crazy how the "better" product often can't match the old, dangerous one for pure staying power?

Man, that old adhesive was no joke. Modern stuff just doesn't seem to have the same staying power, does it? Maybe they used something we can't even get anymore.

Ugh, tell me about it. My buddy tried to pull up some ancient linoleum in his kitchen last year. That black adhesive was like concrete, it just would not let go. He ended up having to rent a big floor scraper and it took him two full days, said his arms were jelly. That stuff was basically a permanent installation.
