Advice on best way to remove flexible tile adhesive from wooden substrate

[john2k]

I’ve removed porcelain tiles from my wood floor substrate. Was extremely difficult but chipped them all away bit by bit. I’m now left with lots of patches of notched trowel flexible adhesive. The adhesive is the flexible type and is soft it’s not the rock solid cement type. What’s the best way to remove this stuff without too much effort lol?

I saw someone on YouTube using some sort of long handled scraper with a blade. Will this work? What’s it called?

Picture attached.

Thank you.

Um, maybe it's called a long handled scraper? lol

I wonder if a little application of heat (via a heatgun) might help make it easier to remove?
Either way, have a jolly scraping time

I use a Marshalltown 4”scraper, sometimes a wide chisel bit in the sds drill. Either way, it’s a long hard graft !

Would it be easier to lift the wood, turn it over and refit it?
Then you just need to clean off where it meets at the joists.

IF they're 8 X 4 sheets of ply, you'll never get them lifted in one piece- they'll snap and splinter. It's hard to tell from your photo, but on zooming in on the bottom of it, I think your substrate is tile backer board ( maybe the thin insulated ones) and not wood.
Regardless of what it is, i'd be inclined to get under it with a flat ended pry bar and just lift the whole lot.

I fix mine down with Csk screws into pilot holes

As a result of much annoyance taking up old boards that were nailed down.

Slotted screws are easier to remove than pozi because you can scrape them.

Have you tried a shovel or a hoe?

I made a thing for scraping floors years ago that still works well, by cutting the handle off an old wood saw, grinding slots in the blade and mounting it on a T shaped bar of wood (a 3x2 with a piece of ply screwed to it) so the non-toothed side of the blade rubs the floor..

For a technological solution I dare say a floor sander would quickly demolish that with a gritty pad in
