I am working on another rental and the floors need sanded. 2 rooms were farily easy to sand. We used the drum first and then the square buff to finish them the edger was also used.
Then we got into the lower bedrooms the edger just would gum up.
We think it is orange shellac but not sure. After the 3rd edger disc in the 1 wall we decided to stop. We tried the drum with the same result. The drum will get bands of brown material on it it hardens and gets brittle when cool.
Then we thought that we weren't going fast enough to keep it cool. I couldn't move any faster by myself behind it so I had my helper take one handle and myself the other and really moved it fast and was able to sand 1/2 of the room with 3 paper changes. Still not efficient enough.
We are using 24 grit paper and it still plugs. I noticed that the 36 grit plugged a little less but still not good.
the 60 and 80 plugged almost immediately.
We have 1.5 room to go and decided to try to strip it off we used a torch and scrapper and got 75% of it off. Then there is a layer of what looks like polyurathane underneath that that came off occasionally where we got it too hot. We tried again and it still plugs the drum sander and edger and the square buff . It's real humid and the floors feel kind of gummy. Kind of reminds you of when you use old product and it will never really dry properly.
Any Ideas on how to aproach this. We still want hardwood and want to sand it.
I am thinking that some type of hardner or something other than what we are doing.
I have done about 25-45 floors over the years so I have seen enough of them to cover the basics.
