Here's a couple of pic's of the floor I'm refinishing. The first is a pic of how bad the floor was. I've been putting it off as this floor gets used ALL the time. It connects the Kitchen, Living room, hall to BR's & Bath. I used a Cherryhill 4 disk Floor sander http://www.u-sand.com/product_info_.html to sand the floor. It isn't very aggressive and takes longer to use it, but, I didn't have to worry about gouging the floor. The dust collection on this sander is GREAT! Some dust still got out but there was no thick dust cloud. You still need a mask but it actually produced less airborn dust than my ROS does. I had to start with 24grit so I could sand out the gouges that were put in when I used a drum sander 12yrs ago. I worked thru the grits to 100 grit then used a floor buffer with 120grit screen. I used a B&D Mouse for the corners and my ROS for the edging. I used Velvit Oil for the finish (See Barbara Gill's website for info. (I'm not affiliated)), letting it soak in for 45min. and then buffing off the excess. (Hope the colors OK on the pic ) I still need to apply another coat tonight and hopefully get my house back together Tuesday. SWMBO is happy with the floor and will be extatic, exctatic, oh hell, REAL HAPPY to sleep in our own bed instead of the sleeper couch in the LR with the boys.
