How Long Does a Floor Sanding Job Take from Start to Finish?

Floor-Sanding

When you decide to revive your tired, scratched timber, one of the first questions on your mind is simple: how long will this actually take? Whether you are restoring Victorian pine boards in an Islington townhouse or updating engineered oak in a modern apartment, planning your life around floor work requires a clear timeline.

At Floor Direct Ltd., we carry out floor sanding & restoration in London properties every week, and while every timber floor has its own personality, a standard residential project usually takes between 2 to 4 days from start to finish.

Here is how that timeline breaks down phase by phase.

Phase 1: Preparation and Board Repairs (Day 1 Morning)

Before any sander turns on, proper room preparation takes about 2 to 4 hours. The room must be fully cleared of furniture, old underlay, and carpet grippers.

Our team inspects every inch of the floor, hammering down exposed nail heads, securing loose boards, and filling gaps between planks with a specialised resin mix. Skipping this step risks damaging sanding equipment and creates an uneven surface, so getting the prep right is essential.

Phase 2: The Sanding Passes (Day 1 Afternoon to Day 2 Morning)

The actual sanding phase takes roughly 1 to 1.5 days for an average room (20–30 square metres). We run heavy-duty drum sanders and specialised edge sanders across the wood in three main passes:

  • Coarse grit (24–36 grit): Removes old varnish and any deep scratches on the wood surface.
  • Medium grit (60–80 grit): Removes grain imperfections and smoothes minor ridges.
  • Fine grit (100–120 grit): Delivers a silky, uniform surface ready to absorb the seal.

Thanks to modern dust-extraction systems, this stage is significantly cleaner and faster than old-school traditional sanding.

Phase 3: Staining, Sealing, and Curing (Day 2 to Day 4)

The finish application will take half a day, but the curing process determines the exact schedule.

  • Water-based lacquers: Need 2 to 3 coats, taking roughly 2–3 hours to dry between coats. You can walk on the floor in socks after 24 hours.
  • Hardwax oils: Require 2 coats with longer drying windows (8 to 12 hours per coat). Full chemical cure takes up to 72 hours.

If you prefer low-maintenance alternatives in high-moisture spaces, exploring vinyl flooring for kitchens might be a better fit, but for real timber, letting the finish dry fully is critical.
