Step by step
Assess wear - light wear may only need a screen-and-recoat, not full sanding.
Clear the room fully and remove baseboards if doing edge sanding.
A drum/orbital sander removes the old finish in progressive grits (36 to 100+).
Vacuum thoroughly and apply stain (if changing color) followed by 2-3 coats of finish.
For most homeowners, hiring a pro is recommended - sanding mistakes gouge the wood permanently.
Questions to ask your pro
- Do you use a dustless sanding system, and how well does it contain fine particles?
- What grit progression do you use, and will you make multiple directional passes?
- What finish do you recommend—oil-based polyurethane, water-based, or hardwax oil—and why for my situation?
- Are any boards too thin from prior sandings, cupped, or damaged and unable to be refinished?
- How long until I can walk on the floor with socks, and how long before furniture can go back?
- What stain options are available, and can I see physical samples on my wood species?
- Are the VOC levels safe for children or pets during and after curing?
