Hi All, We have a large 400SqF room that has a pre-finished floor that is pretty scratched up with deep scratches all across, i'm guessing caused by moving furniture. We tried using markers, to no avail. Also tried sanding just the area around the scratch marks and staining and finishing them, but it's impossible to match the factory finish and stain. So, finally decided to re-send all of the floors ourselves. Went to HD and were recommended to rent random disk sander... I watched videos about the drum sander all week long before going to HD, and I was a fool to listen to the HD worker that recommended the random disk sander. Anyways, after about45 minutes with random disc sander, i realized that i will take me a month to get the finish off, these boards have like 6 layers of poly on it. $68 wasted.. Anyway, went to the local rental store right away to get the drum sander and edger. First drum sander that they gave me broke 4 belts in 5 minutes and made a big gauge in one spot on the floor, good thing i started in a spot that will have a couch on top of it. I started to think that I was using the machine wrong, but after the 4th time I though that it could be the machine, went back to the rental shop and got another drum sander as a replacement. Now, this thing was so much better, not a single time did the belt break and worked really well. I was able to get the whole floor sanded with a 20 grit once, and since I did not have time ( the local rental store closes at 5) got about 2/3 of the floor sanded with 80 grit. Also sanded the corners and edges with 36 and 80 grit paper. Now, the question i have is what should i do now? I have all of the finish off, but the floor has some spots sanded with 80 and some with 20 grit still. What is the cheapest and smart thing to do? I really do not want to rent out a drum sander again because i might get a bad one and make a gauge in the floor again. Do you think if I get the random orbital sander and start say with 60 grit, then 80 and then 100 or 120, I should be able to get it to a state where i can stain and finish it. I want to get the sanding done in 1 day. Thanks in advance for your help and sorry for long story.. :)

Anyone has any experience with those?

Looks like all I need is a smallest mat, a thermostat, and 120V power supply connected through thermostat. What say you? I figure about 60 degrees inside the cabin should do the job. Just a hunch.
