Hi,
We've just removed some carpet from our new place and are planning to sand and re-finish the original wood floors - however we discovered that much of it is covered with a black paint/finish that is burning through the abrasive on the belt sander. I'd be really grateful for any tips about removing this pre-sanding because as it stands the abrasive on the sander lasts about ten minutes before it gets too coated to continue. Any tips greatly appreciated!
Many thanks!
