How to Care for an Engineered Oak Floor

Oak carries a reputation for being demanding. That reputation was earned by unsealed solid boards that needed regular sanding and polishing, and it has been kept alive since by suppliers of synthetic flooring who benefit from it.

A modern engineered board is a different object. Ours carry a UV cured lacquer finish, with the exception of Vuitton and Clair, which use a different finish system. The lacquer bonds to the timber, resists moisture, holds colour, slows UV fading and gives the hard, scratch-resistant surface you actually clean. In practice the floor asks for less than most vinyl.

Here is the whole routine.

Weekly

Vacuum with a soft-bristle attachment to lift dust, sand and grit. Check the wheels are clean and rolling freely, because a seized wheel is one of the more common causes of fine scratching. Grit is abrasive, so this step matters more than mopping.

Mop with a microfibre pad and a cleaner formulated for timber floors. Work with the grain, then dry with the mop until almost no moisture remains. The floor should be dry within two to three minutes. If it is not, the mop was too wet.

What to use, and what not to

Use only wood floor cleaners. General purpose cleaners leave residue that dulls the finish and is difficult to remove once it has built up. We recommend the Bona floorcare range, which is widely stocked through hardware stores.

Do not dilute it. Bona cleaners are formulated for use at full strength. Diluting reduces cleaning power, weakens the protective properties of the product and makes streaking considerably more likely.

Do not use a steam mop. Heat and moisture driven into a joint is the fastest way to damage a timber floor, and it will void the Warranty.

Wash microfibre pads regularly. A loaded pad redistributes dirt rather than removing it.

The full routine is set out in the After Care Guide, which we recommend passing to the client at handover.

Keeping the room stable

Timber responds to its environment, so the most effective maintenance happens before you pick up a mop.

Aim for relative humidity between 40 and 60 per cent, and temperature between 16 and 27 degrees. In a New Zealand home that usually looks after itself, but a dehumidifier or humidifier is worth having in genuinely damp or genuinely dry locations.

If the floor is over underfloor heating, the 27 degree surface limit applies, and commissioning should be gradual. That detail is covered in the Underfloor Heating Declaration and in our underfloor heating guide.

Sunlight

Direct sun causes heat build-up and, over time, uneven colour. Two habits handle it.

Leave rugs off for the first three months so the floor develops its colour evenly. After that, move rugs and freestanding furniture occasionally so no area is permanently masked. UV-treated glazing, blinds or curtains do the rest. We cover the mechanism in detail in does wooden flooring fade.

Everyday protection

• Lift furniture rather than dragging it, and fit felt pads to every leg.
• Deal with spills promptly and address leaks immediately.
• Use breathable mats at entrances. Rubber-backed mats trap moisture against the finish.
• Keep pet nails trimmed and put a mat at the door the dog uses.
• Check shoes for embedded stones before they cross the floor.

Independent results for how the surface handles common household substances are published as the KLUMPP Stain Resistance Test, which dates from 2015.

Deep clean, every two to four years

Regular cleaning does not reach everything. A professional with a wood floor scrubber will lift the film of dirt and grime that accumulates below the level a mop reaches. It is a noticeable difference, and it is not expensive relative to what it protects.

Recoating, every ten years or so

Eventually the protective coating shows wear. There are two responses, and they are different jobs.

Light sand and recoat. For minor scratching and general dulling, a professional lightly abrades the surface and applies a fresh matte coat. The floor is not taken back to bare timber.

Full sand and refinish. For discolouration, deep scratching or a floor that has simply had a long life, it is sanded to bare oak, re-stained if desired, and recoated. Each pass takes about 1mm. Nobody sands a floor to its last millimetre, because enough oak has to remain for the board to stay sound and the tongue and groove to hold, so 6mm gives four or five passes with a safe residual underneath. That is where the manufacturer's figure of approximately four to five comes from.

Damage to a single board does not require either. See repairing an oak floor.

Holiday homes

A house that sits empty for months is a harder environment than one in daily use, because nothing is regulating humidity or ventilation. A local caretaker checking in periodically is the simplest answer. A portable humidifier or an HRV system handles the rest.
