Homeowners want one answer: "How many days will my house be upside down?" After 15+ years refinishing floors across Maryland — from Severn ranchers to Annapolis waterfront homes to old Baltimore rowhouses — I can give you a very honest number. For a typical 1,000 sq ft project, plan on 4 to 5 working days of crew on-site, plus 2 weeks of finish cure before the rugs go back down.
But that is the short version. The longer version matters, because the wrong assumptions about drying and cure time are the #1 reason homeowners damage a brand-new finish in the first month. Here is the full picture.
Quick Answer: Hardwood Refinishing Timeline at a Glance
| Milestone | Typical Timing | What It Means |
|---|---|---|
| Full crew on-site | 4 – 5 days | Sanding, staining, and poly coats applied |
| Walkable (socks only) | 24 hours after final coat | Light foot traffic, no shoes |
| Shoes allowed | 48 hours after final coat | Soft-soled, clean shoes |
| Furniture back | 72 hours after final coat | Carry in, do not drag |
| Rugs back | 2 – 3 weeks | Wait for full cure |
| Full cure (water-based) | 14 days | Finish at full hardness |
| Full cure (oil-based) | 21 – 30 days | Finish at full hardness |
Maryland-specific note: If we are refinishing in July or August, high humidity can add 12–24 hours to total project time. Dry Maryland winters in January–February are actually our fastest refinishing window.
Day-by-Day: What Happens on a Typical Maryland Refinish
Here is exactly what your schedule looks like for a 1,000 sq ft refinish with stain change and three coats of water-based polyurethane — the most common setup we run in 2026.
Day 1 — Prep, Furniture, and First Sand
We arrive around 8 a.m. Before a single sander is plugged in, we spend an hour protecting the rest of the house: plastic sheeting over doorways, painter's tape around vents and return registers, and HVAC shut down to prevent dust migration. If you booked our free furniture-moving service this month, the crew moves everything out of the refinish zone now.
Then the drum sander comes out. The first pass uses coarse 36-grit paper to strip the old finish and cut through surface damage. For a 1,000 sq ft open-plan first floor, first-pass sanding typically takes 4–6 hours. We use low-dust refinishing equipment with HEPA vacuum-connected sanders — not truly 100% dustless, but dramatically cleaner than traditional drum sanding from 15 years ago.
Day 2 — Intermediate Sanding, Edging, and Repairs
Day 2 is the detail day. We run second and third drum sander passes with 60-grit then 100-grit paper to refine the surface. Then the edger comes out for every border, closet, and tight corner the drum sander cannot reach. This is where slow, careful work matters: a sloppy edger job shows up as "halos" around the room perimeter after stain is applied.
Any board-level repairs — gap filling, loose nail driving, small patch replacements — happen at the end of Day 2 while we have the bare wood exposed and clean.
Day 3 — Vacuum, Tack, and Stain Application
Before stain, the entire floor gets vacuumed with HEPA filtration and then wiped with a tack cloth. Any speck of grit trapped under the finish becomes a permanent bump, so this is slow, deliberate work. For natural-finish floors (no stain change), we skip to polyurethane on Day 3 and save a full day.
For color changes, stain goes on with a lambswool applicator or rag, worked into the grain, and wiped off after the dwell time specified on the can (usually 3–10 minutes). The stain then needs to dry overnight before polyurethane goes on top — minimum 8 hours for water-based compatible stains, 24 hours for traditional oil-based stains.
Day 4 — First Two Poly Coats
With water-based polyurethane, we can typically apply two coats in a single day — one in the morning, light buff, one in the afternoon. Each coat is applied with a T-bar applicator in long, overlapping strokes. Dry time between coats is 2–4 hours depending on humidity.
With oil-based polyurethane, only one coat per day is possible because each coat needs 8–12 hours to dry before the next. This is the main reason oil-based refinishes run longer.
Day 5 — Final Coat and Walkthrough
The final coat goes on in the morning. By late afternoon the surface is dry to the touch. We do a final walkthrough with you before we leave, noting any normal cure-time behavior to expect (slight off-gassing smell for 48–72 hours with water-based, longer with oil-based).

No two jobs are identical. Here are the variables that shift a refinish from 4 days to 7+ days.
Square Footage
- Under 500 sq ft (single room): 2–3 days on-site
- 500–1,200 sq ft (first floor): 4–5 days on-site
- 1,200–2,000 sq ft (whole home): 5–7 days on-site
- Over 2,000 sq ft: 7–10 days, often split into zones
Oil-Based vs Water-Based Polyurethane
Oil-based extends your project by 2–3 days because each coat needs 8–12 hours to dry before the next. Water-based coats recoat in 2–4 hours. For full details on which to choose, read our guide on oil vs water-based polyurethane.
Stain Change vs Natural Finish
Staining adds 1–2 days. Dark stains (ebony, espresso) typically need 24–48 hours to dry fully before polyurethane. Natural-finish refinishes skip this entirely.
Maryland Humidity
This one surprises homeowners. On a 90°F / 85% humidity July afternoon in Anne Arundel County, polyurethane dry times can double. We plan around this: summer jobs often get scheduled with an extra buffer day, and we run dehumidifiers on-site during high-humidity weeks. In contrast, dry January air lets water-based poly dry in under 2 hours between coats.
Number of Coats
Two coats is acceptable for low-traffic rooms (guest bedrooms, formal dining). Three coats is our standard for main living areas and kitchens. Four coats is worth it for commercial or heavy-dog households. Each added coat is about 4 hours plus dry time.
Old Baltimore Rowhouses and Historic Homes
Original pine and heart-pine floors in homes from the early 1900s often have irregular widths, cut nails protruding, and previous paint layers trapped in the grain. These take 1–2 extra days of prep because the drum sander cannot move as fast and hand-scraping is sometimes required.
The Part Homeowners Skip: Cure Time
Dry time and cure time are different things, and mixing them up is how brand-new refinishes get ruined in the first month. Here is the difference:
- Dry time = the solvent or water has evaporated. The surface feels dry. You can walk on it.
- Cure time = the polymer chains have fully cross-linked. The finish is at its rated hardness and chemical resistance.
A floor can be "dry" in 24 hours but still "curing" for 2–4 weeks. During cure, the film is soft enough that a rubber-backed rug can off-gas, create pressure marks, or even lift color off the finish if placed too early.
Cure-time rules we give every Maryland customer: No rugs for 14 days (water-based) or 21 days (oil-based). No wet mopping for 30 days. Felt pads on every furniture leg before it touches the floor. No rolling office chairs on bare finish for 30 days.
When Can I Move Back In?
This depends more on tolerance for off-gassing smell than on floor readiness:
| Activity | Water-Based | Oil-Based |
|---|---|---|
| Sleep in same house (other rooms) | Day of final coat | 24 hours after final coat |
| Sleep in refinished room | 48 hours | 72–96 hours |
| Walk on floor (socks) | 24 hours | 24 hours |
| Move furniture back | 72 hours | 72 hours |
| Pets on floor | 48 hours | 72 hours |
| Rugs back | 14 days | 21–30 days |
Comparing Refinish vs Full Replacement Timeline
Many clients weigh refinishing against full replacement. If you are still on the fence, read our breakdown on refinishing vs replacement. The timeline difference is significant:
- Refinish: 4–5 days on-site + 2 weeks cure
- Full replacement (site-finished): 7–10 days on-site + 2 weeks cure
- Full replacement (prefinished): 4–6 days on-site, no cure period
Prefinished hardwood is the fastest option total, but you give up the seamless look of a site-finished floor and the ability to fully sand flat across room transitions.
How to Prepare Your Home to Keep the Timeline Tight
You can speed up your own project by 1–2 days with good prep:
- Empty the rooms before Day 1. Any furniture still in the way on arrival costs us 2–4 hours of moving time. If you booked free furniture moving, you are fine — we handle it.
- Remove wall art and fragile items. Sanding vibration can knock picture frames off walls.
- Take down curtains and drapes. Dust clings to fabric and re-contaminates the floor.
- Plan pet and kid logistics. Pets cannot be in the work zone during the 4–5 day window. A boarding or grandparents stay is the cleanest solution.
- Schedule appliance work beforehand. If your fridge or stove needs to be disconnected, do it before Day 1, not in the middle of the project.
