I would like my floor to have a stain. Is this something I could do myself? Will there be a lot of dust created from your sanding machines? Should I have the gaps between the boards filled? How long will the work take? Who will be working at my home? Are my floorboards too far gone to sand? Will there be a lot of noise created from your sanding machines? I have a concrete hearth, can anything be done? Which floor finish should I choose? What are wood slivers? Can I stain my own floor? What colour will the floor be after sanding? How do I choose a colour for my floor?
