Описание: (UPDATE) I added captions to this since I have had SO many complaints that they could not hear what I said. Im sorry the audio is Garbage. It was an Impromptu capture and I was MILES from any of my audio gear. And even AI audio enhancement could not fix this I decided to Close Caption it so please turn on captions to see what I said.. Yes I missed a few things that were not important ..
Helping my girlfriend remodel her moms house I discovered by accident how to remove joint compound from the floor with ease. First I tried scraping it with a floor scraper wow that was a huge pain and didn’t work so well. Then I grabbed my Ryobi Palm sander and some drywall sand paper and wow that was doing great but the dust was horrible. I ran out of pieces to continue. So I started hand sanding due to this stuff being such a bumpy mess. I got wore out so I cleaned the dust then mopped . As I was walking out I seen some of the compound lifted so I grabbed the scraper and it pealed off like butter. So I tried another spot and wow it’s coming off quickly with ease. I kept going till it started getting tough then I grabbed the mop and re wet it. An decided to record hope this helps someone .
