How to remove glued chipboard chunks from TG subfloor
I’m replacing a floor that was engineered planks glued to chipboard subfloor, and it all had to come out. The chipboard was glued and nailed, and has left lots of “residue” of glued chipboard, which I have to remove. It was glued down with normal floor construction adhesive about 13 years ago, and the glue is tough and hard.
I have about 150 sq ft of this to deal with, and finding an efficient removal method would help out a lot.I’ve tried a “spud” scraper with some success but it’s slow and noisy, as well as occasionally digging into the T&G.
I was pondering getting a heat gun to possibly soften it up, and then perhaps even just use a hand scraper. I haven’t yet dug out my power planer; that would be a little less physical than the spud scraper, though not any less noisy, and I’m afraid it won’t be much faster.
Anyone have any experience with this situation that could offer some advice?

That looks like particle board. Soak it with water and see what happens, it'll probably disintegrate, then you just have to find out how to remove the glue.
I'll vote with soaking with water. That press board will crumble after a good soak and what remains will loosen up easily with a heat gun. I doing the same right now with luan glued and stapled down to subfloor (sans the water because the luan doesn't care if it gets wet)
Hello
you will achieve better results with cutting the old subfloor into managble sections and removing. Then install your new subfloor
good luck

All you can do is experiment. A good hot-air gun might do it (none of those effete don't-wanna-start-a-fire units). Water might do it. Maybe you could figure out to operate a wallpaper steamer horizontally, to combine water and heat.
