How long do I need to stay off hardwood floors after refinishing in NB?

You should stay off your hardwood floors in socks for at least 24 hours after the final coat of polyurethane, and avoid normal foot traffic for 48-72 hours. Full curing — when the finish reaches maximum hardness and durability — takes significantly longer, and New Brunswick's humidity conditions play a direct role in how quickly that happens.

The critical distinction is between dry time and cure time. Dry time is when the surface is no longer tacky to the touch — typically 4-8 hours for oil-based polyurethane and 2-4 hours for water-based polyurethane under ideal conditions. But the finish is still soft and vulnerable at this stage. Cure time is when the finish has chemically hardened to its full strength, and this takes much longer: 7-10 days for water-based polyurethane and 14-30 days for oil-based polyurethane. During this curing window, your floors need special care.

Here is a practical timeline for NB homeowners. 24 hours after the final coat: you can walk on the floors in clean socks only — no shoes, no bare feet (skin oils can mark uncured finish), and no pets. 48-72 hours: light foot traffic in socks or soft-soled indoor shoes is fine. 5-7 days: you can move lightweight furniture back, but place felt pads on all legs first. 14 days (water-based) or 30 days (oil-based): you can place area rugs back down — putting rugs on uncured finish traps solvents and can leave permanent marks or discolouration. Heavy furniture and appliances should wait the full cure period.

New Brunswick's Maritime climate directly affects these timelines. During the humid summer months (June through August), when indoor humidity can climb above 60% without air conditioning, both oil-based and water-based finishes cure more slowly. Your 24-hour dry time might stretch to 36-48 hours, and full cure time extends proportionally. Running a dehumidifier or air conditioner to keep indoor humidity between 40-50% speeds the process significantly. Conversely, during NB's dry winter heating season when indoor humidity drops to 20-30%, finishes can dry too quickly on the surface while remaining soft underneath — a condition called surface skinning that leads to wrinkling and peeling. Maintaining 35-45% humidity with a humidifier during winter refinishing helps the finish cure properly from bottom to top.

Temperature also matters. Polyurethane needs a minimum room temperature of 10-15 degrees Celsius to cure properly, and ideal conditions are 18-25 degrees Celsius. In NB homes where heat is turned down in unused rooms or where refinishing happens in shoulder-season conditions, keeping the space consistently warm speeds curing and produces a harder final finish.

During the curing period, do not wash the floors with water or cleaning products — dry dust mopping only for the first two weeks. Avoid dragging anything across the surface, and keep pet nails trimmed. Place walk-off mats at exterior doors once the finish is dry to the touch, because NB's grit, sand, and salt will scratch uncured finish far more easily than a fully hardened surface.

Planning around these timelines is important — if you have a household with kids and pets, discuss the schedule with your refinishing professional so you can arrange to stay out of the space during the critical first 48-72 hours.
