I thought those cheap plastic floor scrapers were junk, but they saved a job for me yesterday
Had to pull up old vinyl sheet in a kitchen and the adhesive was a nightmare. My usual metal scraper was just gouging the subfloor. Grabbed a $5 plastic one from my truck as a last try. It flexed just enough to get under the glue without digging in, and I cleared the whole 12x14 area in like two hours. Anyone else find a use for a tool you wrote off at first?
