How long refinishing takes
San Diego flooring guides published in 2026 put a full sand and refinish at 3 to 5 days and a screen and recoat at 1 to 2 days. The spread comes from four things: square footage, whether you are staining, which finish goes on top, and how many boards need repair before sanding starts. A 600 square foot living room with a clear water-based finish sits at the short end. A whole 1940s house with stain, stairs and a few replaced boards sits at the long end.
Those are working days. Add the cure time after the last coat before the room is back in full use, which runs from 3 to 5 days on the water-based products below and longer on oil-based. Tidal Flooring writes the day count and the furniture date into the estimate after measuring the floor, so you can plan around a date.
What happens each day
The sequence is the same on every job; only the hours per step change. A clear water-based finish on a sound floor compresses the steps below into three days. Stain, repairs and oil-based finish each add time.
- ◆Assess and protect. The crew checks moisture in the boards and the thickness of wood left above the tongue, confirms the stain sample on your floor, then masks doorways, vents and cabinets. The dust-contained sanders are connected and tested.
- ◆Rough sand. Coarse abrasive takes off the old finish and levels the boards. This is the loud day and the one that makes the most dust, which the containment system pulls at the drum.
- ◆Fine sand, repairs and filler. Finer grits remove the scratch pattern from the first pass. Loose boards are fastened, damaged boards are replaced, and gaps are filled where the wood is stable enough to hold filler. Edges and corners are hand-detailed.
- ◆Stain, if any. Stain goes on and must dry fully before anything covers it; this is the step that most often adds a day.
- ◆Sealer. The first coat locks in the color and raises the grain, and is buffed smooth once dry.
- ◆Topcoats. Two or three coats of finish, each dried and lightly abraded before the next. Manufacturer data for Bona's water-based finishes puts dry time at 2 to 3 hours per coat in normal conditions, so two coats often fit in one day.
When you can walk, move furniture and lay rugs
Dry and cured are different words. A floor is dry when you can touch it without marking it. It is cured when the finish has hardened all the way through and can take furniture legs, rolling chairs and a rug that traps moisture. The finish you choose sets the ladder.
Manufacturer data for two common water-based products: Bona Traffic HD dries in 2 to 3 hours per coat, can be walked on after 24 hours, is 80 percent cured after 1 day and fully cured after 3 days, and the data sheet says not to put area rugs back until it is fully cured. Bona Mega ONE is 75 percent cured after 24 hours and fully cured after 5 days. Both sheets note that high humidity and low temperature extend drying.
- ◆Socks: after 24 hours on a water-based finish (manufacturer data).
- ◆Shoes and light furniture: when the crew clears it, usually once the finish is most of the way cured. Get the day in writing.
- ◆Full furniture: after full cure, 3 days for Traffic HD and 5 days for Mega ONE. Lift, do not slide, and put felt pads on every leg.
- ◆Rugs: only after full cure, per the manufacturer. A rug laid early traps moisture against soft finish and can leave a mark that stays.
- ◆Oil-modified polyurethane: slower at every rung. The exact hours come from the product's own data sheet, so plan on the longer end and follow the written schedule from your crew.
Staying in the house: dust, odor and pets
Most families stay home during a refinish, with two adjustments. The rooms being sanded are off limits for the whole job, and the route from the front door to the bedrooms has to avoid them. A one-story home with hardwood in every room is the case where a few nights elsewhere makes sense.
Dust. Tidal Flooring sands with dust-contained equipment that captures most of the dust at the source. It is not zero. A fine film can still settle in rooms next to the work, so closing doors, covering electronics and turning off forced-air heating or cooling during sanding keeps it to a wipe-down.
Odor. Water-based finishes have low odor and air out within hours; the house is livable the same evening with windows open. Oil-based polyurethane carries a solvent smell for days and needs real ventilation, and people with asthma or small children usually choose to sleep elsewhere until the last coat has dried. Pets: keep them off the floor until the crew says it is walkable, since claws mark soft finish, and keep them out of the house on oil-based coating days.
Your prep checklist before the crew arrives
The crew's first morning goes faster, and the estimate stays accurate, when these are done the night before.
- ◆Clear the rooms: furniture, rugs, lamps and anything on the floor. Ask whether furniture moving is in your estimate or priced separately; do not assume.
- ◆Take down wall art and fragile shelf items in and next to the work area. Sanders vibrate.
- ◆Empty closets if their floors are being refinished, and clear the bottom of built-ins.
- ◆Plan the route and the pets. Decide where the family and the animals will be on sanding and coating days.
- ◆Turn off the HVAC when asked, and point out the electrical panel. Sanding equipment draws heavy power and may need a specific circuit; this is checked at the estimate.
- ◆Show the crew the trouble spots: squeaks, a soft board, the water ring under the old plant stand. Repairs are cheaper to plan than to discover.
- ◆Approve the stain on your floor, not on a chip. Samples go on a sanded patch so you see the real color on your wood.
What moves the schedule in San Diego
Two local factors show up again and again. The first is the coast. Marine-layer mornings in La Jolla, Point Loma, Coronado and Del Mar keep humidity high, and the manufacturer data for water-based finishes says high humidity and low temperature extend drying. A coat that would be ready for the next pass by lunch inland can push to late afternoon near the beach, which is how a 3 day job becomes a 4 day job. Crews plan coat timing around it; you plan the furniture date with a margin.
The second is the age of the floor. Point Loma, North Park, Mission Hills and Coronado have oak and fir floors from the 1920s to the 1950s that have been sanded before. Thin boards limit how aggressive the sanding can be. The usual surprises are carpet staples and tack strips, pet stains that run deep into the grain, old shellac or wax that has to come off before new finish will bond, and a few cracked or cupped boards. Each adds hours; a replaced board adds time to sand the patch flush. This is why the thickness check on day one matters: it tells the crew what the floor can take.
Screen and recoat: the 1 to 2 day alternative
If the finish is worn but the wood under it is not, you may not need a full refinish. A screen and recoat abrades the existing finish just enough for a new topcoat to bond, then applies one or two coats. There is no bare wood, no stain and far less dust. San Diego guides put it at 1 to 2 days, and Swell's 2026 planning range is $2 to $4 per square foot against $4 to $9 for a full sand and finish.
It only works when the old finish is intact. Gray or black boards, scratches through to the wood, cupping, and floors that were waxed or cleaned with oil soaps are not candidates, because the new coat has nothing sound to grip. The free in-home estimate includes the adhesion check that decides between the two. See the recoat page for how the test works, and the refinish-or-replace guide if the boards themselves are the problem.
