We've been working on this house. All the floors had carpet. Most of the floors were covering hardwood, which merely required pulling and staple removal. The family room was a different story. The family room had carpet, but under the carpet was a layer of nasty 1960's linoleum GLUED TO THE HARDWOOD. This first video is a time lapse of Lucy taking her turn chipping away at the top layer.
Then, Becky steamed off the gluey paper layer while wearing a gas mask, saving the work for while the rest of us were at work/school so as not to give us all mesothelioma.
We didn't get a video of the sanding that took place next, but it necessitated a very large and powerful machine and produced about a full trash can full of sawdust. The staining took about 20 minutes. Becky did the polyurethane, again to keep the rest of our lungs safe, which then required a couple nights at a hotel or grandma's house.
Suck on that, Betty Foster.
