Floor Bully 6 in. Flooring Scraper

I’m not sure but mine is easily removing vinyl flooring that’s installed over old linoleum.

No.. I wouldn't recommend it for that purpose. The blade isn't that thin for that purpose. If you were removing the Hardwood floors, it would be perfect.

In my (inexpert) opinion, this might be too aggressive for that.

We have removed many black mastic applied tiled floors with this. However it does not remove the mastic.

You do NOT want to mess with the old black glue ,which was called Cut -Back adhesive. It never dries and as a flooring installer I always skim patch over that specific floor glue that is under various types of vinyl tiles . The very old cut back glue had trace amounts of asbestos in it and so did the old 9x9 tiles you find in old farm houses and buildings. Industry standard is to patch over that glue on concrete its only dangerous when you scrape it or when in- experienced DIY guys try flat troweling new adhesive over it which is also a no no.. because it causes the cut back adhesive to retain its properties and ooze through the crack of any flooring laid over it. Skim patch it until its very smooth and level than install as new concrete.

No. The blade is made more for Demo purposes, removing flooring. The head has a bit of weight and would be great at Raming against hardwood or ceramic tile but it's not razor sharp to be used as a scraper
