How Long Does Floor Sanding Actually Take?
The most common question: how long will this take? Here's the honest answer for a typical Newcastle home.
The Short Answer
Most 3-bedroom homes take 2-3 working days. You can walk on the floor in socks after 24 hours. Full cure (rugs, furniture, normal life) takes 7 days.
Day by Day
Day 1 -- Sanding. This is the noisy day. Belt sander takes the floor back to raw timber, edger does the perimeters, orbital finisher smooths everything out. Industrial dust extraction runs the entire time. By end of day the floor is bare, smooth timber.
Day 2 -- Filling and first coat. Gap filling goes in first thing. Once it's set, a light sand to clean up, then the first seal coat of polyurethane goes down. This coat soaks into the timber and seals the grain.
Day 3 -- Top coats. Light sand between coats, then two final coats of poly. Water-based can go on same day (2-3 hour dry time between coats). Solvent-based needs overnight between coats, so this might push to day 4.
What Affects the Timeline
Floor condition: A floor with heavy damage, old paint, or glue residue takes longer to sand back. Floor size: A small apartment might be one day. A large home could be four. Finish type: Solvent-based takes longer to dry between coats. Repairs: Board replacement or extensive gap filling adds time.
The 7-Day Cure
The floor is walkable in socks after 24 hours, but the polyurethane continues to harden for 7 days. During this time: no shoes, no rugs, no heavy furniture, no wet mopping. After 7 days, normal life resumes.
